Display substrate, preparation method thereof and 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, ...

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

[0003] In the prior art, a plurality of barrier columns 41 that are formed synchronously with the spacers and have the same shape as the spacers are usually closely arranged to make the barriers 4 arranged at the four corners of the sealant 3 to prevent the sealant 3 from The aspirated matter contaminates the display area 1 of the display panel, and the overall shape of each blocking column 41 in the barrier 4 is wedge-shaped, there will be a gap between the blocking column 41 and the top of the blocking column 41, and there will still be a sealant 3 from the gap precipitation, resulting in corner light leakage
