Description

Technical Field

[0001] The utility model relates to a liquid crystal material display technology, in particular to an array substrate, a color film substrate and a liquid crystal material display module. Background Art

[0002] At present, the liquid crystal material display module includes a relatively laminated array substrate and a color filter substrate. When designing and manufacturing the substrate, the film thickness outside the display area of ​​the array substrate and the color filter substrate is lower than the film thickness inside the display area. The periphery of the display area often causes display abnormality due to insufficient support when pressed. In order to maintain the uniformity of the cell thickness, PS (polystyrene material) is often added outside the display area of ​​the array substrate and the color filter substrate to enhance the support effect of the cell thickness.

[0003] A driver chip is bound to the array substrate. The driver chip and the array substrate have different expansion coefficients. In a high temperature environment, due to the different expansion coefficients, the driver chip and the array substrate expand inconsistently, resulting in stress between the driver chip and the array substrate, causing the array substrate to deform near the driver chip. The convex part of the deformed array substrate lifts up the PS outside the display area, thereby squeezing the liquid crystal material, and the liquid crystal material accumulates at the concave part of the deformed array substrate, eventually causing display abnormality, specifically, whitening near the two ends of the driver chip. Utility Model Content

[0004] In order to solve the above-mentioned deficiencies of the prior art, the utility model provides an array substrate or a color filter substrate, which can avoid display MURA caused by deformation between the driving chip and the array substrate.

[0005] The utility model discloses a liquid crystal material display module, which comprises the above-mentioned array substrate or color film substrate.

[0006] The technical problem to be solved by the utility model is achieved through the following technical solutions:

[0007] An array substrate comprises a display area and a non-display area, wherein a PS is arranged in the non-display area and surrounds the periphery of the display area; a driver chip is bound to the non-display area, and the driver chip has a first end and a second end opposite to each other; the PS is provided with a first hollow area and a second hollow area on a side facing the driver chip, wherein the first hollow area corresponds to the first end of the driver chip, and the second hollow area corresponds to the second end of the driver chip.

[0008] Furthermore, the array substrate further comprises a first substrate and a TFT array layer, the TFT array layer is arranged on one side surface of the first substrate, and the PS is arranged on one side surface of the TFT array layer facing away from the first substrate.

[0009] Furthermore, the first substrate is a glass substrate.

[0010] Furthermore, the orthographic projection points of the first end and the second end of the driving chip on the PS fall in the middle of the first hollowed-out area and the second hollowed-out area respectively.

[0011] A color film substrate is used to be bonded to an array substrate, wherein a driver chip is bound to the array substrate, and the driver chip has a first end and a second end opposite to each other; the color film substrate comprises a display area and a non-display area, a PS is arranged in the non-display area, and the PS surrounds the periphery of the display area; the PS is provided with a first hollow area and a second hollow area on a side facing the driver chip, the first hollow area corresponds to the first end of the driver chip, and the second hollow area corresponds to the second end of the driver chip.

[0012] Furthermore, the color filter substrate further includes a second substrate and an RGB color filter layer, the RGB color filter layer is arranged on one side surface of the second substrate, and the PS is arranged on one side surface of the RGB color filter layer facing away from the second substrate.

[0013] Furthermore, the second substrate is a glass substrate.

[0014] Furthermore, the orthographic projection points of the first end and the second end of the driving chip on the PS fall in the middle of the first hollowed-out area and the second hollowed-out area respectively.

[0015] A liquid crystal material display module comprises a relatively bonded array substrate and a color film substrate, wherein the array substrate and the color film substrate are bonded and fixed by a sealant, wherein the sealant surrounds the periphery of the display area, and liquid crystal material is arranged in a sealed space enclosed by the array substrate, the color film substrate and the sealant; the array substrate is the above-mentioned array substrate, or the color film substrate is the above-mentioned color film substrate.

[0016] Furthermore, the PS is located inside the sealant.

[0017] The utility model has the following beneficial effects: the array substrate or color film substrate of the utility model performs partial hollowing processing on the side of the PS facing the driving chip to form a first hollowing area corresponding to the first end of the driving chip and a second hollowing area corresponding to the second end of the driving chip; in a high temperature environment, due to the different expansion coefficients between the driving chip and the array substrate, the stress of the driving chip on the array substrate causes the array substrate to deform near the first end and the second end of the driving chip, wherein the deformation of the array substrate near the first end of the driving chip is transmitted to the first hollowing area, and the deformation of the array substrate near the second end of the driving chip is transmitted to the second hollowing area, and since the PS does not exist in the first hollowing area and the second hollowing area, the deformation of the array substrate will not cause the PS to squeeze the liquid crystal material in the display area, thereby ensuring the display effect of the liquid crystal material display module.
