Referring to fig. 1, fig. 1 is a schematic side view of a baking apparatus according to an embodiment of the present disclosure.
The baking device provided by the embodiment of the application comprises a carrier 10 and a plurality of lamp pins 20, wherein the plurality of lamp pins 20 are all arranged on the carrier 10. It should be noted that the structure of the baking device is not limited to this, for example, the baking device may also include a lamp, etc. The baking apparatus may be an Alignment ultraviolet baking Oven (LC Photo-Alignment UV Oven, UVO). The dominant wavelength of the ultraviolet light may be 200nm to 400nm, or 100nm to 1000nm, for example, the dominant wavelength may also be 313nm, 312nm, 314nm, or 317 nm.
The carrier 10 may be a polyhedron structure, a pentahedron structure, a hexahedron structure, a heptahedron structure, and the like, such as a rectangular parallelepiped structure. The carrier 10 may have another structure.
In some embodiments, the carrier 10 may have a plurality of support legs, by which support may be achieved. Of course, the carrier 10 may be provided without support legs.
In some embodiments, the carrier 10 has a carrying surface 100, and the carrying surface 100 can be located below, above, or at the side of the carrier 10. Wherein the upper side of the carrier 10 and the lower side of the carrier 10 are in opposite directions. With the carrier 10 above and away from the carrier support location. Wherein the side of the carrier 10 may be disposed vertically above the carrier 10 or may be disposed obliquely above the carrier 10.
The carrying surface 100 can carry an object, for example, the carrying surface 100 can fix a plurality of lamp pins 20. A plurality of lamp pins 20 may be spaced on the carrying surface 100. Wherein one end of the lamp pin 20 is fixed on the carrying surface 100, and the end of the lamp pin 20 fixed on the carrying surface 100 can be defined as a fixed end. And the other end of the lamp pin may be defined as the top end of the lamp pin 20. It is understood that the top end of the lamp pin 20 is disposed opposite to the fixed end of the lamp pin 20.
In some embodiments, the carrying surface 100 has a light reflecting area 101. The light reflecting region 101 may be formed directly on the mounting surface 100, and the light reflecting region 101 may be formed on the mounting surface 100 by machining, injection molding, or the like. The retroreflective region 101 may also be formed by one or more retroreflective structures secured to the support surface 100, such as one or more retroreflective panels secured to the support surface 100 to form the retroreflective region 101. The reflective plate may be a diffusive reflective plate or a specular reflective plate. The light reflecting area 101 may reflect the received light, and in some embodiments, the light reflecting area 101 may emit the received light in a predetermined direction.
In some embodiments, the light reflecting region 101 surrounds a plurality of lamp pins 20, and the light reflecting region 101 can reflect light received by the light reflecting region to the periphery of the lamp pins 20. The predetermined direction is a direction toward the periphery of the lamp pin 20 or a direction toward the top of the lamp pin 20. The display panel may be baked toward the carrying surface 100. For example, the carrying surface 100 faces downward, or the carrying surface 100 faces the direction supported by the carrier 10. The display panel may be baked under the supporting surface, or between the supporting surface 100 and the position supported by the carrier 10. It should be noted that the supporting surface 100 may be located above the carrier, and the display panel may be placed on the supporting surface 100 for baking.
In the actual baking process, the light can be reflected toward the position of the lamp pin 20 through the light reflection region 101, so as to increase the light intensity at the position of the lamp pin 20 and improve the uniformity of the baked display panel.
Referring to fig. 2, fig. 2 is a first schematic top view of a baking apparatus according to an embodiment of the present disclosure.
The plurality of lamp pins 20 include a plurality of first lamp pins 201 and a plurality of second lamp pins 202, the plurality of first lamp pins 201 are arranged at intervals in the first direction L1, and the plurality of second lamp pins 202 are arranged at intervals in the first direction L1. The plurality of first lamp pins 201 and the plurality of second lamp pins 202 are oppositely arranged in the second direction L2, and an oppositely arranged first lamp pin 201 and a second lamp pin 202 form a group.
A first lamp pin 201 and a second lamp pin 202 arranged oppositely can fix a lamp 203. The lamp 203 is used for emitting other light such as ultraviolet rays. The interfaces of the first lamp pins 201 and the interfaces of the second lamp pins 202 are arranged oppositely, so that one end of the lamp tube 203 is connected with the interfaces of the first lamp pins 201, and the other end of the lamp tube 203 is connected with the interfaces of the second lamp pins 202. The lamp 203 can be powered by the first lamp pin 201 and the second lamp pin 202, so that the lamp 203 emits light, and the display panel is baked.
Wherein the first direction L1 and the second direction L2 are different, and the first direction L1 and the second direction L2 may form an included angle greater than zero degrees and smaller than 180 degrees, for example, the first direction L1 and the second direction L2 are perpendicular to each other to form an included angle of 90 degrees, as shown in fig. 2. When the first lamp pin 201 is mainly used as a reference, the second direction L2 extends along the first lamp pin 201 toward the second lamp pin 202. When the second lamp pin 202 is mainly used as a reference, the second direction L2 extends along the second lamp pin 202 toward the first lamp pin 201.
The light reflecting area 101 includes a first light reflecting area 1011 and a second light reflecting area 1012, the first light reflecting area 1011 surrounding the plurality of first lamp pins 201. The second light reflecting area 1012 surrounds the plurality of second lamp pins 202. The first light reflecting region 1011 and the second light reflecting region 1012 are spaced apart from each other, and the space formed by the first light reflecting region 1011 and the second light reflecting region 1012 is located between the plurality of first lamp pins 201 and the plurality of second lamp pins 202. The first light reflecting region 1011 and the second light reflecting region 1012 form a space at a position intermediate the plurality of first lamp pins 201 and the plurality of second lamp pins 202. The first light-reflective region 1011 and the second light-reflective region 1012 are equally sized.
Furthermore, the first light-reflecting region 1011 and the second light-reflecting region 1012 do not surround the first lamp base 201 and the second lamp base 202.
On the other hand, there is a spaced area between the first light-reflecting area 1011 and the second light-reflecting area 1012. The central axis of the lamp 203 is taken as a reference, and the central axis of the spacing region coincides with the central axis of the lamp 203. The spacing region is divided by a central axis into two sub-spacing regions, wherein the two sub-spacing regions are equal in width.
In the actual baking process, the display panel is placed above the supporting surface 100 and the lamp 203 or the display panel is placed below the supporting surface 100 and the lamp 203. The display panel is baked by the light emitted from the lamp 203, and since the positions of the plurality of lamp pins 20 do not emit light, the portion of the display panel on the top of the lamp pins 20 is baked with a weaker light than the middle position.
Therefore, the light reflecting area 101 reflects light, so that the light at the position of the lamp pin 20 can be increased, and the uniformity of the baking device in baking the display panel is improved. On the other hand, the non-uniformity of the display panel display caused by the black spots generated by the non-uniformity of the light receiving of the display panel is reduced.
Referring to fig. 3, fig. 3 is a schematic light ray diagram of a light reflection area of a baking device according to an embodiment of the present disclosure.
In some embodiments, because the light emitted by the tube 203 is diffused all around. When a portion of the light is emitted to the first reflection region 1011 and the second reflection region 1012, the light can be reflected to the first lamp pin 201 and the second lamp pin 202, so that the non-light-emitting region where the first lamp pin 201 and the second lamp pin 202 are located can have the light to irradiate the display panel 30. In addition, if a portion of the display panel 30 is located at the first lamp pin 201 and the second lamp pin 202 during baking, and because light at the first lamp pin 201 and the second lamp pin 202 is weak, the portion of the display panel 30 at the first lamp pin 201 and the second lamp pin 202 may receive weak light during baking of the display panel 30. The display panel 30 receives a portion of the stronger light and a portion of the weaker light, resulting in uneven illumination of the display panel 30. Since the illumination of the baking device is not uniform, a portion of the display panel 30 receiving weak light is prone to generate black dots during the display process, resulting in display non-uniformity.
Therefore, the light emitted from the lamp tube 203 passes through the first and second light reflecting regions 1011 and 1012 or the plurality of light reflecting regions 101, and reflects the light to the periphery or top position of the first and second lamp pins 201 and 202, so that the light at the first and second lamp pins 201 and 202 is enhanced, as shown in fig. 3. Then, since the light at the first lamp pins 201 and the second lamp pins 202 is enhanced, uniformity of the baking apparatus when baking the display panel 30 is improved, and display uniformity of the display panel 30 is also improved, thereby reducing the occurrence of black spots during the display process.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a light reflection area of a baking apparatus according to an embodiment of the present disclosure.
The light reflection area 101 may be a roughness structure 11. The roughness structure 11 may reflect the received light signal to the surrounding or top position of the lamp pin 20. The light-reflecting region 101 is not limited to the roughness structure 11, and may be formed of a light-reflecting sheet, a light-guiding sheet, or the like.
Wherein, the roughness structure 11 can be a plurality of concavely arranged grooves 111 and a plurality of convexly arranged bumps 112. Wherein, a plurality of grooves 111 are arranged at intervals, for example, a plurality of grooves 111 are arranged at equal intervals. The bumps 112 are spaced apart from each other, for example, the bumps 112 are spaced apart from each other. In some embodiments, the plurality of bumps 112 and the plurality of grooves 111 may be arranged side by side with each other, such as: the plurality of bumps 112 are far away from the second pins 202, and the plurality of grooves 111 are far away from the first pins 201. The plurality of bumps 112 and the plurality of grooves 111 may also be disposed in a staggered manner, for example, one or more grooves 111 are sandwiched between the plurality of bumps 112, or one or more bumps 111 are sandwiched between the plurality of grooves 111. The number of the grooves 111 may be greater than that of the bumps 112 or the number of the bumps 112 may be greater than that of the grooves 111, and the application is not limited herein. The arrangement of the plurality of grooves 111 and the plurality of bumps 112 is not limited to the structure of fig. 6. For example, the roughness structure 11 may be a groove 111 connected to a bump 112, and taking a circle as an example, a half of the circle is a groove and a half is a bump. The arrangement can refer to the above contents, and is not described herein.
In some embodiments, the plurality of grooves 111 may have an arc-shaped structure, or the sidewalls of the grooves 111 may be inclined, which may reflect the received light signal to the surrounding or top position of the lamp pin 20. The plurality of bumps 112 may have an arc-shaped structure, or the surface of the bump 112 may be inclined, which reflects the received light signal to the surrounding or top position of the lamp pin 20.
Wherein the roughness 11 reflects light through the grooves 111 and the bumps 112. The light emitted from the lamp tube 203 is reflected by any point in the groove 111. The light emitted from the lamp tube 203 may also be reflected by any point of the convex portion of the convex point 112. Therefore, the light emitted from the lamp tube 203 can be totally reflected by the rough structures 11, thereby preventing some structures which cannot reflect light from being incapable of reflecting light. Light is emitted to the surrounding or top position of the lamp pin 20.
Referring to fig. 5, fig. 5 is another schematic structural diagram of a light reflection area of a baking apparatus according to an embodiment of the present disclosure.
The roughness structure 11 may include a plurality of protrudingly disposed bumps 112. The salient points 112 may be arc-shaped structures, which can reflect light to the periphery or the top of the lamp pins 20, and specific reference may be made to the above contents, which are not described herein again.
Referring to fig. 6, fig. 6 is a schematic view of another structure of the light reflection area of the baking apparatus according to the embodiment of the present application.
The roughness structure 11 may comprise a plurality of concavely arranged grooves 111. The groove 111 may be an arc-shaped structure, and may reflect light to the periphery or the top of the lamp pin 20.
It should be noted that the light-reflecting region 101 according to the embodiment of the present application is not limited thereto, and the light-reflecting region 101 may further include a plurality of sub light-reflecting regions 1010.
Referring to fig. 7, fig. 7 is a second schematic top view of a baking apparatus according to an embodiment of the present disclosure.
The light reflection region 101 includes a plurality of sub light reflection regions 1010, the number of the sub light reflection regions 1010 is equal to the number of the plurality of lamp pins 20, and one sub light reflection region 1010 surrounds one lamp pin 20. That is, one of the plurality of sub light reflecting areas 1010 surrounds a lamp pin 20. One of the plurality of sub light reflecting areas 1010 surrounds one of the second lamp pins 202. For example, the number of the lamp pins 20 is 20, and the number of the sub-reflecting regions 1010 is 20. And the number of the first lamp pins 201 is 10, the number of the sub-reflecting regions 1010 surrounding the first lamp pins 201 is 10. The number of the second lamp pins 202 is 10, and the number of the sub-reflecting regions 1010 surrounding the second lamp pins 202 is 10. And so on.
The number of the sub-reflecting regions 1010 may be different from the number of the lamp pins 20. For example, the number of the sub light reflecting regions 1010 is half of the number of the lamp pins 20, two sub light reflecting regions 1010 are disposed between every two adjacent lamp pins 20, and one lamp pin 20 is spaced between every two adjacent sub light reflecting regions 1010. The light is reflected by the sub-reflecting regions 1010 to the periphery or the top position of the lamp pin 20 between two adjacent sub-reflecting regions 1010.
Referring to fig. 8, fig. 8 is a third schematic top view of the baking apparatus according to the embodiment of the present application.
The support surface 100 may have a matte finish area 40. The light extinction area 40 may absorb light to reduce the intensity of the light at the location of the light extinction area 40. In some embodiments, the extinction region 40 may be absorptive of ultraviolet light or other light.

The light extinction areas 40 may be formed directly on the support surface 100, and the light extinction areas 40 may be formed on the support surface 100 by machining, injection molding, or the like. The matte regions 40 may also be formed by one or more matte structures secured to the support surface 100, such as one or more matte plates secured to the support surface 100 to form the matte regions 101. The extinction plate can be a black metal plate extinction. The light extinction area 40 may absorb light or absorb light that is reflected to the periphery or top position of the lamp tube 203.
Wherein, a light extinction area 40 is arranged between the first lamp pin 201 and the second lamp pin 202.
It should be noted that the brightness of the middle position of the plurality of lamps 203 is stronger than the light intensity of the surrounding or top position of the first lamp pin 201 and the second lamp pin 202. In order to make the display panel 30 receive light uniformly, a part of light having a large illumination intensity is absorbed by the extinction area 40 so as to be consistent with light around or at the top of the first lamp pin 201 and the second lamp pin 202. The display panel 30 is uniformly exposed to light while the display panel 30 is baked, thereby preventing display unevenness of the display panel 30 after baking.
On the other hand, referring to fig. 9, fig. 9 is a fourth schematic top view of the baking apparatus according to the embodiment of the present application.
The extinction region 40 may include a plurality. And one light extinction area 40 is located between two adjacent first lamp pins 201 or between two adjacent second lamp pins 202. Or between two adjacent first lamp pins 201 and between two adjacent second lamp pins 202.
Referring to fig. 10, fig. 10 is a fifth schematic top view of the baking apparatus according to the embodiment of the present application.
The plurality of lamp pins 20 have a light extinction region 40 disposed therebetween. The extinction area 40 is located between the first light-reflective area 1011 and the second light-reflective area 1012. The light-extinction region 40 can absorb light reflected by the first light-reflective region 1011 and the second light-reflective region 1012. The first and second light reflecting areas 1011, 1012 may reflect light, thereby enhancing light at the top of the first and second lamp pins 201, 202. The extinction area 40 and the first and second light reflection areas 1011 and 1012 cooperate with each other to maximize the enhancement of light and to exhibit uniformity, thereby improving the uniformity of the baking apparatus when baking the display panel 30.
Referring to fig. 11, fig. 11 is a sixth schematic top view of the baking apparatus according to the embodiment of the present application.
The toasting device further comprises a plurality of third lamp pins 204 and a plurality of fourth lamp pins 205. Wherein the plurality of third lamp pins 204 are arranged at intervals along the first direction L1. The plurality of fourth lamp pins 205 are arranged at intervals along the first direction L1. The plurality of third pins 204 and the plurality of fourth pins 205 are oppositely arranged in the second direction L2, and an oppositely arranged third pin 204 and a fourth pin 205 form a group. The third plurality of lamp feet 204 are surrounded by the first light reflecting area 1011. A plurality of fourth lamp pins 205 are surrounded by a second light reflecting area 1012. A third lamp pin 204 is located between two adjacent sets of the first lamp pin 201 and the second lamp pin 202.
Here, when the third lamp pin 204 is mainly used as a reference, the third direction L3 extends along the third lamp pin 204 to the fourth lamp pin 205. The third direction L3 extends along the fourth lamp pin 205 toward the third lamp pin 204 when the fourth lamp pin 205 is mainly referred to.
It should be noted that the third lamp pin 204 and the second lamp pin 205 fix a lamp 203. The light tube 203 is used for emitting ultraviolet light or other light.
The extinction area 40 is located between the first light-reflecting area 1011 and the second light-reflecting area 1012, and the extinction area 40 is located between the second plurality of lamp pins 202 and the third plurality of lamp pins 204. The extinction region 40 includes a first extinction region 41 and a second extinction region 42. The first and second light extinction regions 41 and 42 are disposed at intervals from each other. The second light pin 202, the first light extinction area 41, the second light extinction area 42, and the third light pin 204 are arranged in sequence.
In some embodiments the first light-reflective area 1011 and the second light-reflective area 1012 are both 70mm wide. The first and second light-extinction areas 41, 42 are each 10 mm. In addition, a spacing region is formed between the first extinction region 41 and the second extinction region 42, and the spacing region is used for routing.
During the actual baking process, an overlapping region of the lamp pins 20 is formed between the third plurality of lamp pins 204 and the second plurality of lamp pins 202. The overlapping region causes a weak light in the overlapping region because there is a non-light-emitting region where the third lamp pin 204 is located and a non-light-emitting region where the second lamp pin 202 is located. Wherein the third lamp foot 204 is surrounded by the first light reflecting area 1011. The fourth lamp foot 1012 is surrounded by a second light reflecting area 1012. When the lamp tube 203 emits light, the light is reflected to the second lamp pin 202 and the third lamp pin 204 through the first light reflecting region 1011 and the second light reflecting region 1012. Finally, the light in the overlapped area is strengthened. I.e. light enhancement at the second lamp pin 202 and the third lamp pin 204.
However, since the light distribution is divergent, when the light is reflected by the first light reflecting region 1011 and the second light reflecting region 1012, a part of the light is emitted to the overlapping region, i.e., the overlapping region of the lamp tube 203. Because the light in the overlapping area of the lamp tube 203 is stronger by itself, and the light reflected from the first light reflecting area 1011 and the second light reflecting area 1012 easily causes the light in the overlapping area of the lamp tube 203 to be stronger than the light at the second lamp pin 202 and the third lamp pin 204. The first and second light extinction areas 41 and 42 are placed in the overlap area. The extinction area 40 absorbs a portion of the reflected light so that the light at the overlapping area of the lamp tube 203 coincides with the light at the second lamp pin 202 and the third lamp pin 204.
It can be seen that the light of the baking device can be made to be consistent when the baking device is used for baking the display panel 30. The display panel 30 is uniformly illuminated during baking, so that the uniformity of the baking device during baking the display panel 30 is improved, the uniformity of the display panel 30 during displaying is improved, and the condition that the displayed image is not clear due to black spots is prevented.
Referring to fig. 12, fig. 12 is a schematic light ray diagram of a baking device according to an embodiment of the present disclosure.
As can be seen from the light ray diagram of the baking apparatus, the first light reflecting area 1011 and the second light reflecting area 1012 reflect the light rays emitted from the lamp tube 203 to the top ends of the third lamp pin 204 and the second lamp pin 202. The first light extinction area 41 and the second light extinction area 42 absorb the reflected light, so that the overlapping area of the lamp tube 203 and the light at the third lamp pin 204 and the second lamp pin 202 can be consistent even if the light in the baking device is uniform.
In some embodiments, for example, the light around or at the top of the second lamp pin 202 and the third lamp pin 204 is 1, and the light at the lamp tube 203 is 2. If the light is reflected by the first and second light reflecting regions 1011 and 1012 to the surroundings or the top position of the second and third lamp pins 202 and 204 is 0.8, the light of the second and third lamp pins 202 and 204 plus 0.8 is 1.8, and 1.8 approaches 2. The light around or at the top position of the second lamp pin 202 and the third lamp pin 204 is increased. In addition, the 0.8 light can be reflected to the periphery of the lamp tube 203. Therefore, the first extinction area 41 and the second extinction area 42 absorb 0.6 of the light, and the light around the lamp tube 203 is 2.2, and 2.2 approaches 1.8. Therefore, the light in the baking device is uniform, and the uniformity of the display panel 30 during baking is improved.
The embodiment of the application also provides a display panel, and the display panel is placed into the baking device to be baked so as to improve the display uniformity of the display panel.
The embodiment of the application also provides a baking method of the display panel, and provides an intermediate. The intermediate is a thin film transistor liquid crystal display.
