Detailed Description
As described in the background art, the color filter substrate of the prior art is prone to display unevenness. The cause of the display unevenness is analyzed in conjunction with fig. 1 to 3.
Fig. 1 is a schematic structure diagram of a liquid crystal display panel.
Referring to fig. 1, a liquid crystal display panel includes: an outer frame glue 110 located at the perimeter of zone a surrounding zone B and an inner frame glue 120 located at the perimeter of zone B.
Referring to fig. 2, fig. 2 is a schematic cross-sectional structure of the lcd panel shown in fig. 1 along a tangential direction of M-N, including: a color filter substrate 131; a thin film transistor array substrate 132; the frame glue 110 is positioned between the color filter substrate 131 and the thin film transistor array substrate 132; a liquid crystal 150 filled in a cavity (not shown) formed by the color filter substrate 131, the thin film transistor array substrate 132, and the outer frame glue 110; a main spacer layer 141 on the color filter substrate 131; a sub-spacer layer 142 on the color filter substrate 131.
Referring to fig. 3, fig. 3 is a schematic cross-sectional structure of the lcd panel shown in fig. 1 along a tangential direction of M1-N1, including: a color filter substrate 131; a thin film transistor array substrate 132; the sealant 120 is disposed between the color filter substrate 131 and the thin film transistor array substrate 132.
In the above structure, the area a is a display area, the area B surrounded by the area a is used for setting a camera, the outer frame glue 110 located at the periphery of the area a is used for sealing the area a, and the inner frame glue 120 located at the periphery of the area B is used for sealing the area B. The main spacer layer 141 and the auxiliary spacer layer 142 play a supporting role, and when the liquid crystal display panel is subjected to a large external pressure, the main spacer layer 141 can shrink to a certain extent, thereby playing a supporting role. When the external pressure applied to the liquid crystal display panel is further increased, the auxiliary spacer layer 142 can play a role in supporting, so that the thickness of the region a maintains better uniformity, which is beneficial to improving the display effect of the liquid crystal display panel.
However, the periphery of the region B for disposing the camera is sealed by the inner frame glue 120. The inner frame glue 141 is fixed in height due to the small elasticity of the material of the inner frame glue 120. Therefore, when the liquid crystal display panel receives a larger external pressure, the height change of the inner frame glue 141 is smaller, the main spacer layer 141 and the auxiliary spacer layer 142 located on the area a are more elastic, the heights of the main spacer layer 141 and the auxiliary spacer layer 142 can be changed along with the received external pressure, and the area a surrounds the area B, so that a significant gradient change, i.e., uneven display, exists between the thickness of the area B and the thickness of the area a, and the display effect of the liquid crystal display panel is improved.
The thickness refers to a distance between the color filter substrate 131 and the thin film transistor array substrate 132.
To solve the technical problem, an embodiment of the present invention provides a color filter substrate, including: the camera comprises a substrate, a display module and a display module, wherein the substrate comprises a camera area and a display area surrounding the camera area, an isolation area is arranged between the camera area and the display area, and the isolation area surrounds the camera area; a matrix layer on the isolation region, and a first spacer structure on the matrix layer, the first spacer structure having a first modulus of elasticity; the color filter structure comprises a plurality of color filter structures positioned on the display area and a second interval structure positioned on the color filter structure, wherein the second interval structure has a second elastic modulus, and the difference value of the first elastic modulus and the second elastic modulus is within a first preset range. The color filter substrate can effectively improve the problem of uneven display.

The third spacer structure 250 includes one turn of the third spacer layer 251 or multiple turns of the third spacer layer 251.
In this embodiment, the third spacer structure 250 includes two turns of the third spacer layer 251, and the third spacer layer 251 surrounds the camera region a.
In another embodiment, the third spacer structure is a ring of third spacer layers, and the third spacer layers surround the camera region.
In yet another embodiment, the third spacer structure comprises N (N is greater than 3) turns of a third spacer layer, each turn of the third spacer layer surrounding the third region, and N turns of the third spacer layer being concentrically arranged.
In this embodiment, one turn of the third spacer layer 251 in the third spacer structure 250 is an integral structure surrounding the camera area a, and one turn of the third spacer layer 251 includes a plurality of third spacers 255 that are separated from each other.
In other embodiments, each turn of the third spacer layer in the third spacer structure may further include a plurality of third spacers that are separated from each other; or an integral structure of the third spacer layer surrounding the camera head region for each turn in the third spacer structure.
Note that, when the third spacer structure 250 is a plurality of third spacer layers 251, the plurality of third spacer layers 251 are separated from each other.
In this embodiment, the color filter substrate further includes: a fourth spacer structure 260 located on the camera area a, the fourth spacer structure 260 having a third elastic modulus.
Since the color filter substrate further includes: a fourth spacing structure 260 located on the camera area a. When the color filter substrate is subjected to external pressure, the fourth spacer structure 260 can change with the external pressure due to the third elastic modulus of the fourth spacer structure 260, so that the thickness of the camera area a can be contracted to a certain extent. And the difference value between the third elastic modulus and the first elastic modulus is within a second preset range, so that the thickness variation value of the camera region A and the thickness variation value of the isolation region C are within a smaller range, obvious gradient variation between the thickness of the isolation region C and the thickness of the camera region A is avoided, and the color filter substrate can be improved to display uniform effects.
The difference value between the third elastic modulus and the first elastic modulus is within a second preset range; the second preset range is 0-5%.
The color filter substrate further includes: a liquid crystal layer (not shown) filled between the color filter structures 220 and between the second spacing structures 240.
It should be noted that, when the top surface of the first spacer structure 230 is higher than the top surface of the fourth spacer structure 260, the first spacer structure 230 includes at least one first spacer layer 231 as a unitary structure.
In this embodiment, the top surface of the first spacer structure 230 is higher than the top surface of the fourth spacer structure 260, the first spacer structure 230 includes two circles of the first spacer layers 231, and each circle of the first spacer layers 231 is an integral structure, so that the first spacer structure 230 can play a role in isolation, and the liquid crystal layer in the display area cannot enter the camera area a through the isolation area C, which causes pollution to the camera area a, and further can improve the performance of the color filter substrate.
In other embodiments, the first spacer structure top surface may also be lower than the fourth spacer structure top surface. Because the fourth interval structure is located on the camera area, when the top surface of the fourth interval structure is higher than that of the first interval structure, the fourth interval structure can play a role in isolation, so that a liquid crystal layer in a display area cannot enter the camera area, pollution is caused to the camera area, and the performance of the color filter substrate can be improved.
In this embodiment, a portion of the fourth spacer structure 260 is also located on the surface of the matrix layer 210.
Although the present invention is disclosed above, the present invention is not limited thereto. Various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the invention, and the scope of the invention should be assessed accordingly to that of the appended claims.
