Description
BACKGROUND
1. Field
Methods and apparatuses consistent with exemplary embodiments
relate to three-dimensional (3D) glasses which operate in
association with a 3D display apparatus in order to view a 3D
image, and a system for wireless power transmission.
2. Description of the Related Art
In recent years, display apparatuses able to provide not only
two-dimensional (2D) images but also stereoscopic 3D images have
been developed. In particular, a display apparatus for viewing
stereoscopic 3D images may be a glasses-type display apparatus
which uses special glasses or a non-glass type display apparatus
which does not require glasses.
A glasses-type display apparatus used with special glasses may use
a color filter method in which an image is separated into a
left-eye image and a right-eye image using complementary color
filters, a polarizing filter method which separates the image using
a light-shielding effect based on a combination of orthogonal
polarization elements, or a shutter glasses method in which the
left-eye and right-eye of a viewer are alternately blocked in
response to a sync signal in coordination with the projection of
the left-eye image and the right-eye image onto a display
screen.
In order to provide a stereoscopic 3D image, a display apparatus
using the shutter glasses method controls the left-eye glass and
the right-eye glass of a pair of 3D glasses to be alternately tuned
on or off in response to the sync signal transmitted from the
display apparatus.
In other words, power for driving the 3D glasses for viewing the 3D
image is needed. In order to supply power to the 3D glasses in a
related-art method, a disposable battery is inserted into the
glasses or the 3D glasses are charged using a universal serial bus
(USB) cable. The method requiring the user of a disposable battery
is inconvenient in that it requires the replacement of the battery
and may be expensive. Also, the method of charging the 3D glasses
using a USB cable inconveniently requires the use of the USB cable
every time the 3D glasses are charged, and it may spoil the beauty
of the 3D glasses.
Therefore, there is a demand for a method of wirelessly charging 3D
glasses with ease.

art are not described in detail since they would obscure the
embodiments with unnecessary detail.
FIG. 1 is a block diagram illustrating a system 100 for wireless
power transmission according to an embodiment. As shown in FIG. 1,
the system 100 for wireless power transmission includes a power
transmission apparatus 110 for transmitting power wirelessly and a
power reception apparatus 120 for receiving the power from the
power transmission apparatus 100 wirelessly.
The power transmission apparatus 110 converts electric energy
supplied from a power supply part into magnetic energy, and
transmits the converted magnetic energy to the power reception
apparatus 120 wirelessly through a resonance transmission part. The
power transmission apparatus 110 may be implemented as a cradle for
holding 3D glasses, a remote controller, a 3D display apparatus, or
another device as would be understood by one of skill in the
art.
In particular, the resonance transmission part included in the
power transmission apparatus 110 includes a transmission conductive
wire loop which is formed along an edge of the power transmission
apparatus 110 and a first resonance capacitor which is connected to
the transmission conductive wire loop. The power transmission
apparatus 110 will be explained in detail with reference to FIG. 2
and FIGS. 4A to 4C.
The power reception apparatus 120 receives the magnetic energy
transmitted from the power transmission apparatus 110 wirelessly
through a resonance reception part, and converts the received
magnetic energy into electric energy and stores the electric energy
in a battery. The power reception apparatus 110 may be implemented
as 3D glasses or a remote controller.
The resonance reception part of the power reception apparatus 120
includes a reception conductive wire loop which is formed along an
edge of the power reception apparatus 120 and a second resonance
capacitor which is connected to the reception conductive wire loop.
The power reception apparatus 120 will be explained in detail with
reference to FIG. 3 and FIGS. 5 to 7.
Hereinafter, a method for wirelessly charging of the system 100 for
wireless power transmission will be explained with reference to
FIGS. 2 and 3. FIG. 2 is a block diagram illustrating the power
transmission apparatus 110 according to an embodiment. As shown in
FIG. 2, the power transmission apparatus 110 includes a
transmission circuit part 111, a transmission feeder part 112, and
a resonance transmission part 115 including a first resonance
capacitor 113 and a transmission conductive wire loop 114.
The transmission circuit part 111 generates an alternating current
(AC) waveform of a high frequency using a direct current (DC)
voltage transmitted from a power supply part (not shown), and
generates a magnetic field. Also, the transmission circuit part 111
generates a magnetic field concentrated on a resonant frequency.
The transmission circuit part 110 generates the AC waveform of the
high frequency (MHz level) and excites the transmission feeder part
112.
The transmission feeder part 112 excites the resonance transmission
part 115 which is connected in an inductive coupling pattern,
thereby inducing generation of a magnetic field concentrated on a
specific frequency. The specific frequency may be 13.56 MHz. The
transmission feeder part 112 includes a feeder conductive wire loop
which induces an electric current in the resonance transmission
part 115.
The resonance transmission part 115 generates the magnetic field
concentrated on the specific frequency. The resonance transmission
part 115 includes the transmission conductive wire loop 114 which
is formed along the edge of the power transmission apparatus 110
and the first resonance capacitor 113 which is connected to the
transmission conductive wire loop 114. The transmission conductive
wire loop 114 may be a metal plate which consists of any one of Cu,
Al, and Steel Plated-Tin, Electrolytic (SPTE).
In other words, the resonance transmission part 115 serves as an LC
resonator so that the resonance transmission part 114 can change
values of a capacitor and an inductor and thus change the quality
factor (Q factor) and a resonant frequency.
As described above, the magnetic energy generated by the resonance
transmission part 115 of the power transmission apparatus 110 is
wirelessly transmitted to the power reception apparatus 120.
FIG. 3 is a block diagram illustrating the power reception
apparatus 120 according to an embodiment. As shown in FIG. 3, the
power reception apparatus 120 includes a resonance reception part
123 including a reception conductive wire loop 121 and a second
resonance capacitor 122, a reception pick-up part 124, a
rectification part 125, a DC to DC conversion part 126, and a

The resonance reception part 123 receives the magnetic energy
having the specific frequency. More specifically, the resonance
reception part 123 includes the reception conductive wire loop 121
which is formed along the edge of the power reception apparatus 120
and the second resonance capacitor 122 which is connected to the
reception conductive wire loop 121. The reception conductive wire
loop 121 may be formed using a printed circuit board (PCB) or a
film PCB.
The resonance reception part 123 is activated by the magnetic field
of the specific frequency generated in the resonance transmission
part 115 such that an electric current flows in the resonance
reception part 123.
The reception pick-up part 124 is inductive-coupled to the
resonance reception part 123 to receive the energy from the
resonance reception part 123. The reception pick-up part 124
includes a pick-up conductive wire loop in which the electric
current generated in the reception conductive wire loop 121 is
induced.
The rectification part 125 rectifies the AC voltage transmitted
from the reception pick-up part 124 to a DC voltage. The
rectification part 125 may include a bridge diode having four
diodes and a capacitor serving as a filter. Another circuit for
rectifying the AC to the DC may be used as the rectification part
125.
The DC to DC conversion part 126 adjusts an input voltage to be
constant since the DC voltage rectified by the rectification part
125 may not always be constant.
The charging part 127 charges the rectified constant voltage. The
charging part 127 may include a charging integrated circuit (IC)
and a battery for controlling a charging operation using the output
voltage of the rectification part 126. The battery may be a super
capacitor.
The power reception apparatus 120 may further include a wireless
communication part (not shown) for communicating with an external
apparatus. The power reception apparatus 120 may control a charging
operation of at least one of a resonance part including the
resonance reception part 123 and the reception pick-up part 124,
the rectification part 125 and the charging part 127 according to
control information received through the wireless communication
part.
The external apparatus may be a remote controller or a 3D display
apparatus. In other words, the power reception apparatus 120 may
stop or begin the charging operation according to control
information received from a remote controller or the 3D display
apparatus.
Also, the wireless communication part may be a Bluetooth
module.
As described above, the power reception apparatus 120 is wirelessly
charged by the magnetic field of the specific frequency so that
charging is more convenient for the user.
Hereinafter, various exemplary embodiments of the power
transmission apparatus 110 will be explained with reference to
FIGS. 4A to 4C.

However, this is merely an example, and the power transmission
apparatus 110 may have a different configuration from that of the
stand type cradle of FIG. 4A.
FIG. 4B is a view illustrating a case where the power transmission

apparatus 110 may have a different configuration from that of the
box type cradle shown in the second drawing of FIG. 4B.
Although the box type cradle has been described in FIG. 4B, the
technical idea of the present disclosure may be applied to the
power transmission apparatus 110 of a cylindrical cradle.
FIG. 4C is a view illustrating a case where the power transmission
apparatus 110 is a 3D display apparatus according to an embodiment.
In this embodiment, the power is transmitted wirelessly through the
3D display apparatus and the power reception apparatus 120 is
charged by the 3D display apparatus.
As shown in FIG. 4C, the transmission conductive wire loop 114 is
disposed in a frame of the 3D display apparatus and the first
resonance capacitor 113 may be disposed on an area of the frame of
the 3D display apparatus (for example, an upper middle area). The
transmission circuit part 111 and the transmission feeder part 112
may be disposed on an external apparatus or a lower support.
However, this is merely an example and the power transmission
apparatus 110 may have a different configuration from that of the
3D display apparatus of FIG. 4C.
Hereinafter, an embodiment in which the power reception apparatus
120 is 3D glasses will be explained with reference to FIGS. 5 to
6C.
FIG. 5 is a view illustrating a case in which the power reception
apparatus 120 is a pair of 3D glasses according to an embodiment.
The 3D glasses include a frame which includes a first lens holder
part 150, a second lend holder part 155, and a bridge part 160 to
connect the first lens holder part 150 and the second lens holder
part 155, and a temple 170. Although one temple 170 is illustrated
in FIG. 5, this is only for the convenience of explanation and it
is clear that another temple 170 may be included at the other side
of the 3D glasses.
As shown in FIG. 5, the reception conductive wire loop 121 and the
pick-up conductive wire loop 124 are mounted in the frame and
follow an edge of the frame. More specifically, as shown in FIG.
6A, the reception conductive wire loop 121 and the pick-up
conductive wire loop 124 may extend into the first lens holder part
150, the second lens holder part 155, and the bridge part 160.
Alternately, as shown in FIG. 6B, the reception conductive wire
loop 121 and the pick-up conductive wire loop 124 may be disposed
in only the first lens holder part 150. As shown in FIG. 6C, the
reception conductive wire loop 121 may be disposed in only the
first lens holder part 150, whereas the pick-up conductive wire
loop 124 may be extend into the first lens holder part 150, the
second lens holder part 155, and the bridge part 160.
However, these are merely an examples, and the reception conductive
wire loop 121 and the pick-up conductive wire loop 124 may be
mounted in the frame in a different manner from those illustrated
in FIGS. 6A to 6C.
As shown in FIG. 5, the second resonance capacitor 122 may be
mounted in the temple 170. However, this is merely an example and
the second resonance capacitor 122 may be mounted at any one of the
first lens holder part 150 and the bridge part 160.
Also, as shown in FIG. 5, the rectification part 125, the DC to DC
conversion part 126, and the charging part 127 may be disposed in
an earpiece portion of the temple 170. However, this is merely an
example and the rectification part 125, the DC to DC conversion
part 126, and the charging part 127 may be disposed in different
parts of the 3D glasses.
FIG. 7 is a view illustrating a case in which the power reception
apparatus 120 is a remote controller according to an embodiment. In
other words, the remote controller shown in FIG. 7 may be charged
using the magnetic energy wirelessly transmitted from the external
power transmission apparatus 110.
As shown in FIG. 7, the reception conductive wire loop 121 may be
disposed in a frame of the remote controller and the second
resonance capacitor 122 may be disposed in a part of the frame of
the remote controller (for example, a lower end portion). Also, the
pick-up conductive wire loop 124, the rectification part 125, the
DC to DC conversion part 126, and the charging part 127 may also be
included in the remote controller. However, this is merely an
example and the power reception apparatus 120 may have a different
configuration from that of the remote controller.
According to the various exemplary embodiments described above, the
power reception apparatus 120 such as the 3D glasses or the remote
controller is charged wirelessly without a cable so that charging
the power reception apparatus 120 such as the 3D glasses or the
remote controller is more convenient for a user.
The foregoing exemplary embodiments and advantages are merely
exemplary and are not to be construed as limiting the present
inventive concept. The exemplary embodiments can be readily applied
to other types of apparatuses. Also, the description of the
exemplary embodiments is intended to be illustrative, and not to
limit the scope of the claims, and many alternatives,
modifications, and variations will be apparent to those skilled in
the art.
