Problems solved by technology

like figure 1 and 2 As shown, under the premise that the original process equipment is not modified, after the sealant 3 (Seal glue) is applied, the sealant 3 in the four corners of the peripheral area 2 of the display substrate (Panel) is relatively large. Since the product frame is narrow, the large sealant 3 It is easy to touch the display area 1 (AA area) of the display panel. Even if it is not in contact, the suction of the sealant 3 will easily move into the display area 1. At this time, there will be corner light leakage defects, and this defect The ratio is more common in the actual product

Example Embodiment

[0024] Example 1:

[0025] combine image 3 and 4 As shown, this embodiment provides a display substrate, which includes: a display area 1 and a peripheral area 2 surrounding the display area 1, a sealant 3 is provided in the peripheral area 2, and the display substrate further includes: The retaining wall 5 at the corner of the sealant 3 and close to the display area 1 is an integral structure.

[0026] It should be noted here that the retaining wall 5 refers to a complete structure without gaps. The one-piece structure can be formed by splicing several graphics, but it must be ensured that there is no gap at the splicing position.

[0027] In the display substrate of this embodiment, the retaining wall 5 with an integral structure is used as the retaining wall 5 at the corner of the sealant 3, so it can well prevent the suction material at the corner of the sealant 3 from polluting the display area 1 of the display substrate, and at the same time seal the The glue 3 will...

Example Embodiment

[0034] Example 2:

[0035] This embodiment provides a method for preparing a display substrate, wherein the display substrate may be the display substrate described in Embodiment 1. The method for preparing the display substrate includes: forming a retaining wall 5 at the corners of the sealant 3 , preferably each corner, and at a position close to the display area 1 , wherein the retaining wall 5 is an integral structure.

[0036] Specifically, the display substrate may be a color filter substrate or a COA substrate. Hereinafter, taking the display substrate as a color filter substrate as an example, the method for preparing the display substrate of this embodiment will be described. The preparation method of the color filter substrate specifically includes:

[0037] A black matrix (BM; BLACKMATRIX) is formed on the base through processes such as coating, exposure, development, and baking, and a color filter is formed on the display area 1 of the base through processes such...

Example Embodiment

[0043] Example 3:

[0044] This embodiment provides a display device, wherein the display device includes the display substrate of Embodiment 1.

[0045] Of course, the display device in this embodiment can be any product or component with a display function such as a mobile phone, a tablet computer, a television, a monitor, a notebook computer, a digital photo frame, a navigator, and the like.

[0046] Certainly, the display device in this embodiment also has structures such as an outer frame of a conventional display device.

Abstract

The invention provides a display substrate, a preparation method thereof and a display device, belonging to the technical field of displays. The display substrate comprises a display region, a periphery region and a baffle wall, wherein the display region is surrounded by the periphery region, and sealing gum is arranged at the periphery region; the baffle wall is arranged at the position at the corner of the sealing gum, is close to the display region and is of an integrated structure. According to the display substrate provided by the invention, compared with obstacles which are synchronously formed by partitions and consist of multiple baffling pillars in the prior art, the baffle wall which is of an integrated structure is taken as a baffle, the stability and the uniformity of the height and the width of the baffle wall are relatively good, furthermore, the pollution caused by aspirates of the sealing gum to the display region of the display substrate can be relatively prevented, meanwhile, the sealing gum cannot overflow from the position of the baffle wall, and the light leakage of the sealing gum from the corner of the sealing glue can be effectively prevented.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a display substrate, a preparation method thereof, and a display device. Background technique [0002] Narrow bezel has always been a technology that terminal manufacturers are keen on, and it is also a goal that panel manufacturers have been pursuing. In addition to testing the layout and thinning of transistors, narrow bezel design is more of a challenge to product yield. like figure 1 and 2 As shown, under the premise that the original process equipment is not modified, after the sealant 3 (Seal glue) is applied, the sealant 3 in the four corners of the peripheral area 2 of the display substrate (Panel) is relatively large. Since the product frame is narrow, the large sealant 3 It is easy to touch the display area 1 (AA area) of the display panel. Even if it is not in contact, the suction of the sealant 3 will easily move into the display area 1. At this time, ...
