replaced by the wireless charging, and electronic devices are no
longer limited to the use of charging lines when charged.
Therefore, the hassle of using charging lines is avoided.
[0077] However, an additional wireless charging devices needs to be
provided for a conventional electronic device to wirelessly
charging the conventional electronic device, which results in the
increase of the thickness of electronic device, thus the appearance
of the electronic device is affected. To overcome the defect, a
touch screen, an electronic device, a wireless charging method and
a wireless charging system are provided according to the present
disclosure.
[0078] Before the introduction of the wireless charging of the
electronic device, the wireless charging technology is explained
first. The wireless charging technology utilizes near-field sensing
to transmit energy from a wireless charger to an electronic device
to be charged. The battery of the electronic device is charged by
the received energy and provides energy for the operation of the
electronic device. Since the wireless charger transmits energy to
the electronic device by inductive coupling, no wire connection is
required, and there is no conductive contact exposed. At present,
there are three kinds of wireless charging modes, which includes
electromagnetic induction charging, magnetic resonance charging and
radio-wave charging. Take the electromagnetic induction charging as
an example, the operating principle of the electromagnetic
induction charging is that an alternating current of a certain
frequency in a transmitting coil causes a current in the receiving
coil by electromagnetic induction in an alternating current
electromagnetic field, thus the energy can be transmitted from an
output end to an receiving end to perform the wireless
charging.
[0079] In the present disclosure, the wireless charging is
performed by using a touch screen, which is applied to an
electronic device. The electronic device includes but is not limit
to a computer, a mobile phone, a tablet computer, a personal
digital assistant (which is abbreviated as PDA) and an on-board
computer. In this way, the electronic device can be wirelessly
charged by using the touch screen directly without an additional
wireless charging device. FIG. 1 is a schematic diagram of a touch
screen 100 according to an embodiment. As illustrated in FIG. 1,
the touch screen 100 includes a touch sensor 10 and a touch chip
20. The touch sensor 10 is electrically connected to the touch chip
20. If the touch screen 100 is used for wireless charging, the
touch chip 20 controls the touch sensor 10 to form a receiving coil
or a transmitting coil for performing wireless charging. That is,
the formed receiving coil acts as a charged device for performing
wireless charging when coupled to an external transmitting coil, or
the formed transmitting coil acts as a charging device for
performing wireless charging when coupled to an external receiving
coil.
[0080] In a possible implementation, in addition to controlling the
touch sensor 10 to form the receiving coil or the transmitting
coil, the touch chip 20 further controls the touch sensor 10 to
form a touch matrix if the touch screen 100 is used for touch
control. In this way, the touch screen can not only realize touch
function by forming the touch matrix, but also realize wireless
charging by forming the receiving coil or the transmitting coil.
That is, in practice, in addition to touch function, the touch
screen can realize charging and power supply. The diversity in the
function brings convenience to users. Of course, the touch sensor
can be controlled by the touch chip 20 to switch from a touch
control state to a wireless charging state, or to switch from the
wireless charging state to the touch control state. As can be seen,
the touch screen can be flexibly switched between the touch control
state and the wireless charging state to meet the users' immediate
needs effectively.
[0081] On the basis of the touch screen illustrated in FIG. 1, the
touch screen 100 further includes a control switch 30, as
illustrated in FIGS. 2a, 2b and 2c. The control switch 30
illustrated in FIG. 2a is arranged on the touch sensor 10, which
results in a short connecting line between the touch sensor 10 and
the control switch 30 and a high integrated level of the touch
sensor 10. The control switch 30 illustrated in FIG. 2b is arranged
on the touch chip 20, which results in a short connecting line
between the control switch 30 and the touch chip 20 and a high
integrated level of the touch chip. The control switch 30
illustrated in FIG. 2c is arranged individually, i.e., the control
switch may be individually arranged on a flexible printed circuit
board of the touch screen. In this way, the control switch 30 can
be arranged flexibly. In practice, the control switch 30 can be
arranged on a chip other than the touch chip on the touch screen
and connected to the touch chip through wires, which is not limited
herein.
[0082] Continuing to refer to FIG. 2a to FIG. 2c, the control
switch 30 includes a first port 31 and a second port 32. If the
first port 31 is electrically connected to the touch sensor 10, the
touch sensor 10 forms the touch matrix. If the second port 32 is
electrically connected to the touch sensor 10, the touch sensor 10
forms the receiving coil or the transmitting coil. That is, when
the first port is electrically connected to the touch sensor, the
touch sensor is controlled to form the touch matrix, such that the
touch screen operates in the touch control state. When the second
port is electrically connected to the touch sensor, the touch
sensor is controlled to form the receiving coil, such that the
touch screen can act as a wireless charging receiving device for
performing wireless charging in combination with a wireless
charging transmitting device. Alternatively, when the second port
is electrically connected to the touch sensor, the touch sensor is
controlled to form the transmitting coil, such that the touch
screen can act as a wireless charging transmitting device to
wirelessly charge another electronic device. In practice, when the
coil formed by the touch sensor is connected to a transmitting
circuit, the transmitting coil is formed; and when the coil formed
by the touch sensor is connected to a receiving circuit, the
receiving coil is formed.
[0083] In a possible implementation, the touch sensor 10 is located
in a target area of the touch screen 100. The target area includes
an entire area of the touch screen 100 or a part of the entire area
of the touch screen 100, such as a middle area, an upper-half area,
a lower-half area, a left-half area, a right-half area or the
entire screen. Take the smart phone as an example, where the touch
sensor is located on the entire touch screen. Of course, the touch
sensor can be arranged manually by the user or automatically by the
electronic device. For example, the touch sensor can be arranged by
the user at a designated location of the touch screen based on an
actual demand, which is not limited herein.
[0084] Continuing to refer to FIG. 2a to FIG. 2c, the touch sensor
10 includes first conducting electrodes 11 and second conducting
electrodes 12, the first conducting electrodes 11 and the second
conducting electrodes 12 are arranged across each other at a
predetermined angle, where the predetermined angle is an acute
angle or a right angle, which is not limited herein. The
arrangement of the first conducting electrodes and the second
conducting electrodes includes but is not limited to any one of the
following.
[0085] In a possible implementation, the first conducting
electrodes and the second conducting electrodes are arranged on the
same surface of the same insulating material layer. The first
conducting electrodes and the second conducting electrodes are
arranged across each other at the predetermined angle on the same
plane. The first conducting electrodes and the second conducting
electrodes form capacitive nodes. The number of the first
conducting electrodes is m, the number of the second conducting
electrodes is n, and the first conducting electrodes and the second
conducting electrodes form an array of m times n, where each of m
and n is an integer greater than 1.
[0086] In a possible implementation, the first conducting
electrodes and the second conducting electrodes are respectively
arranged on top surfaces of two insulating material layers or
bottom surfaces of two insulating material layers. The first
conducting electrodes and the second conducting electrodes are
arranged across each other at the predetermined angle on different
planes. The first conducting electrodes and the second conducting
electrodes form capacitive nodes. The number of the first
conducting electrodes is m, the number of the second conducting
electrodes is n, and the first conducting electrodes and the second
conducting electrodes form an array of m times n, where each of m
and n is an integer greater than 1.
[0087] In a possible implementation, the first conducting
electrodes and the second conducting electrodes are respectively
arranged on two surfaces of the same insulating material layer. The
first conducting electrodes and the second conducting electrodes
are arranged across each other at the predetermined angle on
different planes. The first conducting electrodes and the second
conducting electrodes form capacitive nodes. The number of the
first conducting electrodes is m, the number of the second
conducting electrodes is n, and the first conducting electrodes and
the second conducting electrodes form an array of m times n, where
each of m and n is an integer greater than 1.
[0088] The insulating material includes at least one of resin and
inorganic glass. Of course, the insulating material can also be an
insulating material other than resin and inorganic glass, such as
polyterephthalate, polymethyl methacrylate, polycarbonate,
polyurethane and polystyrene, which is not limited herein.
[0089] In practice, the first conducting electrodes 11 and the
second conducting electrodes 12 may be made of a conducting
material of transparent indium tin oxide (which is abbreviated as
ITO). Of course, the first conducting electrodes 11 and the second
conducting electrode 12 may be made of other materials, such as
graphene, METAL-MESH, which is not limited herein. Each of the
first conducting electrodes 11 and the second conducting electrodes
12 may include at least one conducting electrode. The first
conducting electrodes 11 may be arranged at regular intervals, and
the second conducting electrodes 12 may be arranged at regular
intervals. Of course, the first conducting electrodes 11 and the
second conducting electrodes 12 may be arranged in other manners,
which is not limited herein. For example, on the same insulating
material layer, there are m (m>1) rows of the first conducting
electrodes 11 in the transverse direction and n (n>1) columns of
the second conducting electrodes 12 in the longitudinal direction,
to form an array of m times n. The first conducting electrodes and
the second conducting electrodes are arranged on the same surface
or two surfaces of the same insulating material layer, and form
capacitive nodes. As another example, there are m (m>1) rows of
the first conducting electrodes 11 arranged in the transverse
direction on the bottom surface of the two-layer insulating
material and n (n>1) columns of the second conducting electrodes
12 arranged in the longitudinal direction on a higher surface of
the two-layer insulating material. That is, m (m>1) rows of
conducting electrodes and n (n>1) columns of conducting
electrodes form an array of m times n. The first conducting
electrodes and the second conducting electrodes form capacitive
nodes. The shape of each of the first conducting electrodes and the
second conducting electrodes may be triangle, rectangular, round,
elliptic, or other shapes, which is not limited herein. The sizes
of each of the first conducting electrodes 11 and the second
conducting electrodes 12 may be set depend on actual demands, which
is not limited herein.
[0090] In practice, if the touch screen is used for wireless
charging, the m (m>1) rows of the first conducting electrodes 11
or the n (n>1) columns of the second conducting electrodes 12 on
the entire touch screen or a part of the entire touch screen are
connected end-to-end through the control switch under control of
the touch chip to form an S-shaped coil in an X or Y direction,
thereby forming a receiving antenna or a transmitting antenna. The
S-shaped coil in the X or Y direction can be used as a receiving
antenna or a transmitting antenna of the wireless charging device.
Of course, the receiving coil or the transmitting coil may have a
shape other than the S shape, which is not limited herein.
[0091] In practice, when the touch screen is used for touch
control, the first conducting electrodes and the second conducting
electrodes are connected into a touch control configuration by the
touch chip. The touch chip extracts touching information and
reports coordinate information corresponding to the touching
information to a system. When the touch screen is used for wireless
charging, the first conducting electrodes and/or the second
conducting electrodes are connected into a configuration of a
wireless charging receiving coil or transmitting coil by the touch
chip, i.e., the wireless charging receiving coil or transmitting
coil can be formed by the first conducting electrodes or the second
conducting electrodes, or a bigger wireless charging receiving coil
or transmitting coil can be formed by the first conducting
electrodes and the second conducting electrodes, then the touch
chip connects the wireless charging receiving coil or transmitting
coil into the system and monitors the wireless charging state of
the touch screen in a real time manner.
[0092] In practice, the first conducting electrodes may be sensing
(RX) electrodes, the second conducting electrodes may be driving
(TX) electrodes. Reference is made to FIG. 3, which is a schematic
diagram illustrating connection between the touch sensor and the
touch chip. A case where three RX electrodes and three TX
electrodes are provided is taken as an example. The control switch
is arranged on the touch sensor, three pins RX1N, RX2N and RX3N are
respectively arranged on the right ends of the three RX electrodes,
and three pins RX1P, RX2P and RX3P are respectively arranged on the
left ends of the three RX electrodes. A conductive wire RX1P
extended from the left end of the electrode RX1 is connected to a
RX1P terminal of the touch chip, and a conductive wire RX1N
extended from the right end of the electrode RX1 is connected to a
RX1N terminal of the touch chip. A conductive wire RX2P extended

the left end of the electrode RX3 is connected to a RX3P terminal
of the touch chip, and a conductive wire RX3N extended from the
right end of the electrode RX3 is connected to a RX3N terminal of
the touch chip. Three pins TX1P, TX2P, TX3P are respectively
arranged on the upper ends of the three TX electrodes, where a
conductive wire TX1P of the electrode TX1 is connected to a TX1P
terminal of the touch chip, a conductive wire TX2P of the electrode
TX2 is connected to a TX2P terminal of the touch chip, and a
conductive wire TX3P of the electrode TX3 is connected to a TX3P
terminal of the touch chip.
[0093] On the basis of the embodiment illustrated in FIG. 3, the
three sensing (RX) electrodes are taken as an example. FIG. 4 is a
schematic diagram illustrating connection between the touch sensor
and the control switch according to an embodiment. When a port "1"
of the control switch on the upper right side of FIG. 4 is
connected, the equivalent connection mode of the electrode RX1, the
electrode RX2 and the electrode RX3 is as illustrated on the lower
left side of FIG. 4. In this case, the electrode RX1, the electrode
RX2 and the electrode RX3 form a touch matrix, and operate in a
conventional touch control state, such that the touch screen has
the touch function. When the port "2" of the control switch on the
upper right side of FIG. 4 is connected, the equivalent connection
mode of the electrode RX1, the electrode RX2 and the electrode RX3
is as illustrated on the lower right side of FIG. 4. In this case,
the electrode RX1, the electrode RX2 and the electrode RX3 are
connected end-to-end to form an S-shaped receiving coil or
transmitting coil. Specifically, if the S-shaped coil is connected
to a wireless transmitting circuit, the transmitting coil is
formed, and the touch screen has a function of wireless power
supply, and if the S-shaped coil connects to a wireless receiving
circuit, the receiving coil is formed, and the touch screen has a
function of wireless charging.
[0094] On the basis of the embodiment illustrated in FIG. 3, the
three sensing (RX) electrodes are still taken as an example. FIG. 5
is a schematic diagram illustrating connection between the touch
sensor and the control switch according to another embodiment. When
a port "1" of the control switch on the upper right side of FIG. 5
is connected, the equivalent connection mode of the electrode RX1,
the electrode RX2 and the electrode RX3 is as illustrated on the
lower left side of FIG. 5. In this case, the electrode RX1, the
electrode RX2 and the electrode RX3 form a touch matrix, and
operate in the conventional touch control state, such that the
touch screen has the touch function. When a port "2" of the control
switch on the upper right side of FIG. 5 is connected, the
equivalent connection mode of the electrode RX1, the electrode RX2
and the electrode RX3 is illustrated on the lower right side of
FIG. 5. In this case, the electrode RX1, the electrode RX2 and the
electrode RX3 are connected end-to-end to form an S-shaped
receiving coil or transmitting coil, such that the touch screen has
the function of wireless power supply or wireless charging
correspondingly.
[0095] A case where three sensing (RX) electrodes and three driving
(TX) electrodes are provided is taken as an example, as illustrated
in FIG. 6, which is a schematic diagram illustrating connection
between the touch sensor and the control switch according to
another embodiment. The control switch is arranged on the touch
sensor. Three pins RX1N, RX2N and RX3N are respectively arranged on
the right ends of the three RX electrodes, and three pins RX1P,
RX2P and RX3P are respectively arranged on the left ends of the
three RX electrodes. A conductive wire RX1P extended from the left
end of the electrode RX1 is connected to a RX1P terminal of the
touch chip, and a conductive wire RX1N extended from the right end
of the electrode RX1 is connected to a RX1N terminal of the touch
chip. A conductive wire RX2P extended from the left end of the
electrode RX2 is connected to a RX2P terminal of the touch chip,
and a conductive wire RX2N extended from the right end of the
electrode RX2 is connected to a RX2N terminal of the touch chip. A
conductive wire RX3P extended from the left end of the electrode
RX3 is connected to a RX3P terminal of the touch chip, and a
conductive wire RX3N extended from the right end of the electrode
RX3 is connected to a RX3N terminal of the touch chip. Three pins
TX1N, TX2N, and TX3N are respectively arranged on the upper ends of
the three TX electrodes, and three pins TX1P, TX2P, and TX3P are

conductive wire TX1N extended from the lower end of the electrode
TX1 is connected to a TX1N terminal of the touch chip. A conductive
wire TX2P extended from the upper end of the electrode TX2 is
connected to a TX2P terminal of the touch chip, and a conductive
wire TX2N extended from the lower end of the electrode TX2 is
connected to a TX2N terminal of the touch chip. A conductive wire
TX3P extended from the upper end of the electrode TX3 is connected
to a TX3P terminal of the touch chip, and a conductive wire TX3N
extended from the lower end of the electrode TX3 is connected to a
TX3N terminal of the touch chip. When a port "1" of the control
switch on the upper right side of FIG. 6 is connected, the
equivalent connection mode of the driving electrodes TX1, TX2, TX3
and the sensing electrodes RX1, RX2 and RX3 is illustrated on the
lower left side of FIG. 6. In this case, the electrode TX1, the
electrode TX2, the electrode TX3, the electrode RX1, the electrode
RX2, and the electrode RX3 form a touch matrix, and operate in the
conventional touch control state, such that the touch screen has
the touch function. When a port "2" of the control switch on the
upper right side of FIG. 6 is connected, the equivalent connection
mode of the electrode TX1, the electrode TX2, the electrode TX3,

receiving coil or transmitting coil which is perpendicular to the
coil formed by the electrode RX1, electrode RX2 and electrode RX3,
such that the touch screen has the function of wireless power
supply or wireless charging.
[0096] Compared with FIG. 4 and FIG. 5, in FIG. 6, a coil is formed
by the RX electrodes connected end-to-end, and another coil is
formed by the TX electrodes connected end-to-end. The coil formed
by the RX electrodes is connected in series with the coil formed by
the TX electrodes to form a bigger receiving coil or transmitting
coil, such that a greater charging current can be provided.
[0097] In specific application scenarios, the structure of the
touch screen includes but is not limited to Glass-Film-Film (which
is abbreviated as GFF), Glass-Film Multi-point (which is
abbreviated as GFM), One Glass Solution (which is abbreviated as
OGS), ON-CELL, IN-CELL or Glass-Film (which is abbreviated as GF).
The process of wireless charging of the touch screen is described
in combination with specific embodiments in the following.
[0098] FIG. 7 is a schematic structural diagram of a touch sensor
in a touch screen according to an embodiment. The electrode RX1,
the electrode RX2 and the electrode RX3 of the touch sensor are
designed to have an S shape in the transverse direction, and are
connected end-to-end to form a bigger receiving coil or
transmitting coil. That is, a terminal RX1N of the electrode RX1 is
connected to a terminal RX2N of the electrode RX2, a terminal RX2P
of the electrode RX2 is connected to a terminal RX3P of the
electrode RX3, such that a bigger S-shaped receiving coil or
transmitting coil is formed for wireless charging.
[0099] FIG. 8 is a schematic structural diagram of a touch sensor
in a touch screen according to another embodiment. The electrode
RX1, the electrode RX2 and the electrode RX3 of the touch sensor
are designed to have an S shape in the longitudinal direction, and
are connected end-to-end to form a bigger receiving coil or
transmitting coil. That is, a terminal RX1N of the electrode RX1 is
connected to a terminal RX2N of the electrode RX2, a terminal RX2P
of the electrode RX2 is connected to a terminal RX3P of the
electrode RX3, such that a bigger S-shaped receiving coil or
transmitting coil is formed for wireless charging.
[0100] FIG. 9 is a schematic structural diagram of a touch sensor
in a touch screen according to another embodiment. The electrode
RX1, the electrode RX2 and the electrode RX3 are designed to have a
hollowed frame structure, and are connected end-to-end to form a
bigger receiving coil or transmitting coil. That is, a terminal
RX1N of the electrode RX1 is connected to a terminal RX2N of the
electrode RX2, a terminal RX2P of the electrode RX2 is connected to
a terminal RX3P of the electrode RX3, such that a bigger S-shaped
receiving coil or transmitting coil is formed for wireless
charging.
[0101] FIG. 10 is a schematic structural diagram of a touch sensor
in a touch screen according to another embodiment. The electrode
RX1, the electrode RX2, the electrode RX3, the electrode RX4, the
electrode TX1, the electrode TX2, the electrode TX3, and the
electrode TX4 of the touch sensor are designed to form a bridged
structure. The electrodes RX1, RX2, RX3 and RX4 in the X direction
and the electrodes TX1, TX2, TX3, TX4 in the Y direction are formed
on the same insulating material layer. The electrodes in any one of
the X direction and the Y direction are bridged to form a rhombus
array of m rows (m>1) or n columns (n>1) on the entire
screen. When the touch screen is in the wireless charging state,
the rhombic electrodes are connected end-to-end from left to right
to form the receiving coil or the transmitting coil for wireless
charging.
[0102] As illustrated in FIG. 11, which is a schematic structural
diagram of a touch sensor in a touch screen according to another
embodiment, each of the electrodes S1 to S8 of the touch screen is
designed to have a single-layer triangular structure. Paired
triangular electrodes are formed on the same insulating material
layer. N (N>1) pairs of triangular electrodes are formed on the
entire screen. When the touch screen operates in the touch control
state, the electrodes S1 to S8 act as both sensing electrodes and
driving electrodes for detecting self-capacitance. When the touch
screen operates in the wireless charging state, the triangular
electrodes are connected end-to-end from left to right to form a
receiving coil or transmitting coil for wireless charging.
[0103] As illustrated in FIG. 12, which is a schematic structural
diagram of a touch sensor in a touch screen according to another
embodiment, the electrodes SX1 to SX16 of the touch sensor are
designed to have an arrayed self-capacitive rectangular structure.
The rectangular structure is divided into n (n>1) smaller pieces
to form electrodes in an X direction and in a Y direction. When the
touch screen operates in the touch control state, the electrodes
SX1 to SX16 act as both sensing electrodes and driving electrodes
for detecting self-capacitance. When the touch screen operates in
the wireless charging state, the triangular electrodes are
connected end-to-end from left to right to form a receiving coil or
transmitting coil for wireless charging.
[0104] As illustrated in FIG. 13, which is a schematic structural
diagram of the touch sensor in a touch screen according to another
embodiment, each of the electrode TX1, the electrode TX2 and the
electrode TX3 of the touch sensor is designed to have a
double-layer 1T2R pattern structure. Similar to the conventional
GFF structure, the 1T2R pattern structure reduces the number of
traces on the frame, and the touch sensor can be controlled by the
touch chip to form the touch matrix. When the touch screen operates
in the wireless charging state, the electrodes are first connected
end-to-end from left to right, and then connected line by line from
top to bottom, to form the receiving coil or transmitting coil for
wireless charging.
[0105] The specific structures of the touch screen are described
above in detail. Reference is made to FIG. 14, which is a schematic
diagram of a wireless charging method according to an embodiment of
the present disclosure. The wireless charging method is applied to
an electronic device, which includes the touch screen described in
any one of the embodiments illustrated in FIGS. 1 to 13. The
wireless charging method includes the following steps 101 to
104.
[0106] In step 101, a wireless charging control instruction is
obtained.
[0107] The electronic device obtains the wireless charging control
instruction. The wireless charging control instruction may be
control information issued in response to the user's touch on the
touch screen, or may be gesture information, voice information,
graphic information or text information obtained by other ways,
which is not limited herein.
[0108] In step 102, the touch screen is controlled to form the
receiving coil in response to the wireless charging control
instruction.
[0109] If the wireless charging control instruction instructs the
touch screen to operate as the wireless charging receiving device,
the electronic device controls the touch screen to form the
receiving coil in response to the wireless charging control
instruction.
[0110] In step 103, it is determined whether the receiving coil is
coupled to a transmitting coil. The method proceeds to step 104 if
it is determined that the receiving coil is coupled to a
transmitting coil, and the procedure is ended if it is determined
that the receiving coil is not coupled to a transmitting coil.
[0111] In step 104, if the receiving coil is coupled to the
transmitting coil, the electronic device is wirelessly charged via
coupled coils.
[0112] In some possible implementations, the electronic device
further includes a display screen. After controlling the touch
screen to form the receiving coil in response to the wireless
charging control instruction, the display screen is controlled to
display a black screen. In this way, power is saved, and the
privacy of personal information can be protected.
[0113] In some possible implementations, after controlling the
touch screen to form the transmitting coil in response to the
wireless charging control instruction, the wireless charging method
further includes controlling the display screen to display a bright
screen and disabling the touch function of the touch screen. In
this way, although the touch screen is used for performing the
charge function, and the touch function is disabled, by keeping the
screen bright, the user can still obtain relevant display
information from the display screen, such that charging and
displaying can be performed simultaneously.
[0114] In some possible implementations, the touch screen is placed
to face the transmitting coil. In this way, the transmitting coil
covers the surface of the touch screen when the touch screen is
placed to face the transmitting coil, such that the privacy of
personal information can be protected. Of course, in practice, the
touch screen may be placed to face the transmitting coil at a
certain angle relative to the transmitting coil, or may be place in
other ways, which is not limited herein.
[0115] FIG. 15 is schematic diagram of a wireless charging method
according to another embodiment of the present disclosure. The
wireless charging method is applied to an electronic device, which
includes the touch screen described in any one of the embodiments
illustrated in FIGS. 1 to 13. The wireless charging method includes
the following steps 201 to 204.
[0116] In step 201, a wireless charging control instruction is
obtained.
[0117] In step 202, the touch screen is controlled to form the
transmitting coil in response to the wireless charging control
instruction.
[0118] In step 203, it is determined whether the transmitting coil
is coupled to a receiving coil. The method proceeds to step 204 if
it is determined that the transmitting coil is coupled to a
receiving coil, and the procedure is ended if it is determined that
the transmitting coil is not coupled to a receiving coil.
[0119] In step 204, if the transmitting coil is coupled to the
receiving coil, a target electronic device including the receiving
coil is wirelessly charged via coupled coils.
[0120] In some possible implementations, the electronic device
further includes a display screen. After controlling the touch
screen to form the transmitting coil in response to the wireless
charging control instruction, the method further includes
controlling the display screen to display a black screen.
[0121] In some possible implementations, after controlling the
touch screen to form the transmitting coil in response to the
wireless charging control instruction, the method further includes
controlling the display screen to display a bright screen and
disabling the touch function of the touch screen. In this way,
although the touch screen is used for performing the charge
function, and the touch function is disabled, by keeping the screen
bright, the user can still obtain relevant display information from
the display screen, such that charging and displaying can be
performed simultaneously.
[0122] In some possible implementations, the touch screen is placed
to face the receiving coil.
[0123] There are the same or similar contents between the
embodiment illustrated in FIG. 15 and the embodiment illustrated in
FIG. 14. Therefore, one can refer to the description of the
embodiment illustrated in FIG. 14 for detailed description of the
embodiment illustrated in FIG. 15, which is not repeated
herein.
[0124] FIG. 16 is a schematic structural diagram of an electronic
device according to an embodiment of the present disclosure. The

mediums 1630 that store applications 1642 or data 1644 (such as one
or more mass storage devices). The memory 1632 and storage mediums
1630 may be transient or persistent storage devices. The
applications stored in the storage mediums 1630 may include one or
more modules (which are not illustrated in FIG. 16), each module
may include a series of instructions for instructing operations of
the electronic device. Furthermore, the one or more processers 1622
may be configured to communicate with the one or more storage
mediums 1630, and execute the series of instructions in the storage
mediums 1630.
[0125] The electronic device 1600 may also include a display screen
1650, one or more power supplies 1626, one or more wireless or
wired network interfaces 1651, and/or one or more operating systems
1641.
[0126] The steps performed by the electronic device in the above
embodiments can be implemented based on the structure of the
electronic device illustrated in FIG. 16.
[0127] The one or more processers 1622 can make the electronic
device to execute the steps actually executed by the electronic
device in the embodiments illustrated in FIG. 14 and FIG. 15.
[0128] A computer storage media is provided according to an
embodiment of the present disclosure. The computer storage media is
configured to store computer software instructions used by the
above electronic device. The computer software instructions include
programs designed for the methods that are actually performed by
the electronic device in the embodiments illustrated in FIG. 14 and
FIG. 15.
[0129] A wireless charging system is further provided according to
an embodiment of the present disclosure. As illustrated in FIG. 17,
the wireless charging system 1700 includes a first electronic
device 1701 and a second electronic device 1702. The first
electronic device includes the touch screen according to any one of
the embodiments illustrated in FIGS. 1 to 13. One can refer to the
description of the touch screen according to the embodiments
illustrated in FIGS. 1 to 13 for detailed description of the touch
screen, which is not repeated herein. The second electronic device
1702 includes a transmitting coil, which is configured to be
coupled to the receiving coil formed by the touch screen of the
first electronic device 1701 to wirelessly charge the first
electronic device 1701. Specifically, the second electronic device
1702 can be a wireless charging base or other electronic device
which has the wireless charging transmitting function.
[0130] Continuing to refer to FIG. 17, in another implementation of
the wireless charging system, the touch screen of the first
electronic device 1701 forms the transmitting coil, the second
electronic device 1702 includes a receiving coil. The transmitting
coil formed by the touch screen of the first electronic device 1701
is coupled to the receiving coil of the second electronic device
1702 to wirelessly charge the second electronic device.
Specifically, the second electronic device can be any device which
is capable of being wirelessly charged by using an external
charging coil.
[0131] In practice, each of the first electronic device and the
second electronic device can be a terminal with the communication
function. The first electronic device sends a wireless charging
request message to the second electronic device, such that the
second electronic device forms the transmitting coil in response to
the wireless charging request message. The first electronic device
receives a wireless charging confirmation message sent by the
second electronic device, and controls the touch screen to form the
receiving coil in response to the wireless charging confirmation
message. The receiving coil is configured to be coupled to the
transmitting coil to perform wireless charging.
[0132] In practice, the first electronic device can also receive
the wireless charging request message sent by the second electronic
device, and control the touch screen to form the transmitting coil
in response to the wireless charging request message. The first
electronic device sends the wireless charging confirmation message
to the second electronic device, such that the second electronic
device forms the receiving coil in response to the wireless
charging confirmation message. The transmitting coil is configured
to be coupled to the receiving coil to perform wireless
charging.
[0133] In a specific application, a case where a wireless charging
transmitter is a charging base is taken as an example. When the
touch screen of the first electronic device is placed to face the
charging base, the first electronic device automatically searches
for a charging signal and decides whether to switch to the wireless
charging state, or decides whether to switch to the wireless
charging state based on the user's operation. Of course, when the
first electronic device is in a standby state, a sleep state or
another idle state, the first electronic device can also
automatically search for the charging signal. If there is a
charging signal, the first electronic device can automatically
switch to the wireless charging state, which is not limited
herein.
[0134] It may be clearly understood by those skilled in the art
that, for ease of describing and for simplicity, one can refer to
corresponding processes in the above method embodiment for an
