rotated to rise the flexible substrate 13 along therewith so as to
separate it from the glass substrate 11. During the separation,
since a portion of the driver IC 14 on the flexible substrate 13 is
raised up, the component and the like are liable to be damaged due
to the excessively large stress subjected by the flexible substrate
13 when the roller 15 presses.

[0022] Embodiments of the present invention provide an apparatus of
separating a flexible substrate from a glass substrate, and an
equipment of manufacturing the flexible substrate, which are used
for realizing that the driver ICs on the flexible substrate are not
subjected to a press from the roller during a separation of the
flexible substrate from the glass substrate, thereby avoiding
damage to the flexible substrate during the separation.
[0023] Referring to FIG. 2, an embodiment of the present invention
provides an apparatus of separating a flexible substrate from a
glass substrate, which comprises a cylinder-shaped roller 15 and a
control unit (not shown) connected to the roller for controlling
the rotation of the roller so as to separate the flexible substrate
from the glass substrate by the roller. The apparatus further
comprises a depressed area 16 provided on the cylindrical surface
of the roller 15. The depressed area 16 is configured to allow a
driver IC 14 on the flexible substrate 13 to be received by the
depressed area 16 during the rotation of the roller 15, so as to
prevent the roller 15 from contacting with the raised components,
such as the driver IC 14, on the flexible substrate 13.
[0024] According to an embodiment of the present invention, a
control unit (not shown) is provided to be connected to the roller
15 for driving a rotation of the roller 15, so as to separate the
flexible substrate 13 from the glass substrate 11 by means of the
roller 15. The control unit can be an apparatus, such as an
electric motor. The depressed area 16 is configured to prevent the
roller 15 from contacting with the driver IC 14 on the flexible
substrate 13 during the rotation of the roller 15.
[0025] According to embodiments of the present invention, the
roller 15 is provided with one or more depressed areas 16
thereon.
[0026] According to an embodiment of the present invention, when
the flexible substrate 13 is provided with a plurality of driver
ICs 14 thereon, corresponding to every driver ICs 14, a depressed
area 16 is provided on the roller 15, respectively.
[0027] According to an embodiment of the present invention, the
depressed area 16 provided for each of the driver ICs 14 has a
dimension which is matched with that of the corresponding driver IC
14.
[0028] According to an embodiment of the present invention, the
depressed area 16 has a dimension which is larger than that of the
driver IC 14.
[0029] According to an embodiment of the present invention, when
the flexible substrate 13 is provided with a plurality of driver
ICs 14 thereon and the plurality of driver ICs 14 are located in a
same line, the roller 15 thereon is provided with one depressed
area 16 corresponding to a location of this line, and the depressed
area 16 is configured to prevent the roller 15 from contacting with
the plurality of driver ICs 14 located in this line during the
rotation of the roller 15. In this way, the roller is provided with
one depressed area thereon, which avoids the trouble of arranging a
plurality of depressed areas corresponding to every driver ICs,
respectively, thereby the manufacturing process is simplified.
[0030] According to an embodiment of the present invention, the
depressed area 16 provided on the roller 15 is in a cuboid-shape
with dimensions that the width is about 2 mm, the depth is about 2
mm, and the length is no less than the length occupied by the
plurality of driver ICs 14 in a same line.
[0031] According to an embodiment of the present invention, as
shown in FIG. 3, the cylinder of the roller 15 includes a first
section 1, a second section 2, and a third section 3 provided with
the depressed area 16. In combination with FIG. 4, the third
section 3 is movably connected between the first section 1 and the
second section 2, and is rotatable around an axis 5 of the
cylinder. Since the position where the driver IC 14 is located on
the flexible substrate 13 is varying with the size of the flexible
substrate 13, during the roller 15 is rotated to drive a separation
of the flexible substrate 13 from the glass substrate 11, the
driver IC 14 on the flexible substrate 13 is received by the
depressed area 16 by means of the rotation of the third section 3,
so that the separating apparatus as provided by the embodiment of
the present invention is applicable for flexible substrates 13 of
different sizes.
[0032] As shown in FIG. 4, the fastening of the first section 1 and
the second section 2 with the third section 3 on the
cylinder-shaped roller 15 can be made by inserting a jackscrew 4
from side faces of the first section 1 and second section 2. It
should be noted that the roller structure is merely one of the
conceived achievable manners and the present invention is not
limited in such a structure.
[0033] An equipment of manufacturing the flexible substrate,
comprising the described apparatus.
[0034] The weak contact interface 12 as shown in FIG. 2 is a
contact interface between the flexible substrate 13 and the glass
substrate 11.
[0035] Referring to FIG. 5, an embodiment of the present invention
provides a method of separating a flexible substrate from a glass
substrate, comprising steps:
[0036] S1, fastening one end of the flexible substrate onto a
cylinder-shaped roller provided with a depressed area, and
[0037] S2, rotating the roller by a control unit to rise the
flexible substrate along with the roller so as to achieve a
separation of the flexible substrate from the glass substrate.
[0038] The control unit cooperates to control the rotation of the
roller, thereby separating the flexible substrate from the glass
substrate by means of the roller. The control unit can be an
apparatus, such as an electric motor.
[0039] When the roller is rotated to the position of a driver IC
provided on the flexible substrate, the driver IC is received by
the depressed area provided on the roller so that the driver IC is
not subjected to a press from the roller, thereby avoiding damage
to the flexible substrate during the separation.
[0040] The roller includes a first section, a second section, and a
third section provided with the depressed area. The third section
is movably connected between the first section and the second
section, and is rotatable around an axis of the cylinder. Since the
position where the driver IC is located on the flexible substrate
is varying with the size of the flexible substrate, during the
process in which the roller is rotated to drive a separation of the
flexible substrate from the glass substrate, the driver IC on the
flexible substrate is received by the depressed area by means of a
rotation of the third section, so that the separating apparatus
provided by the embodiment of the present invention can be
applicable for flexible substrates of different sizes. In this way,
since the position where the driver IC is located on the flexible
substrate is varying with the size of the flexible substrate, the
driver IC on the flexible substrate can be received by the
depressed area by means of a rotation of the third section, so that
the separating apparatus can be applicable for flexible substrates
of different sizes and with driver ICs provided on different
locations.
[0041] The fastening of the first section and the second section
with the third section on the cylinder-shaped roller can be made by
inserting a jackscrew from side faces of the first section and
second section. It should be noted that the roller structure is
merely one of the conceived achievable manners and the present
invention is not limited in such a structure.
[0042] According to an example, the roller is provided with one or
more depressed areas thereon. In this way, it can prevent the
roller from contacting with the driver IC(s) on the flexible
substrate and from damaging the raised component(s), such as the
driver IC(s).
[0043] According to an example, when the flexible substrate is
provided with a plurality of driver ICs thereon, corresponding to
every driver ICs, the roller is provided with a corresponding
depressed area thereon, respectively. In this way, when the roller
is rotated to the positions of the driver ICs, the plurality of
driver ICs are received by the corresponding depressed areas
without subjecting to a press from the roller, thereby avoiding
damage to the flexible substrate during the separation.
[0044] According to an example, the depressed area has a dimension
which is matched with that of the corresponding driver IC. In this
way, the dimension of the depressed area is just corresponding to
the dimension of the driver IC, which allows the driver IC to be
received by the depressed area when the roller is rotated to the
position of the driver IC. According to an example, the depressed
area has a dimension which is larger than that of the driver IC, so
that the driver IC can be received by the depressed area when the
roller is rotated to the position of the driver IC.
[0045] According to an example, when the flexible substrate is
provided with a plurality of driver ICs thereon and the plurality
of driver ICs are located in a same line, the roller thereon is
provided with one depressed area corresponding to a location of
this line and the depressed area is configured to prevent the
roller from contacting with the plurality of driver ICs located in
this line during the rotation of the roller.
[0046] According to an example, the depressed area provided on the
roller is in a cuboid-shape with dimensions that the width is about
2 mm, the depth is about 2 mm, and the length is no less than a
length occupied by the plurality of driver ICs in a same line. In
this way, the dimension of the depressed area is just corresponding
to the dimension of the plurality of driver ICs in this line, which
allows the driver ICs in a same line to be received by the
depressed area when the roller is rotated to the location of driver
ICs.
[0047] Embodiments of the present invention provide depressed area
on the roller for allowing the driver IC on the flexible substrate
to be received by the depressed area during the rotation of the
roller, which prevents the roller from contacting with the driver
IC on the flexible substrate, so that the driver IC on the flexible
substrate is not subjected to a press of the roller during the
separation of the flexible substrate from the glass substrate. In
such a way, damage to the flexible substrate during the separation
is avoided.
[0048] It is understood that the described above are just exemplary
implementations and embodiments to explain the principle of the
present invention and the invention is not intended to limit
thereto. An ordinary person in the art can make various variations
and modifications to the present invention without departure from
the spirit and the scope of the present invention, and such
variations and modifications shall fall in the scope of the present
invention.
