Display panel, manufacturing method thereof and display device

Abstract

The invention provides a display panel which comprises an array substrate and a counter-covering substrate opposite to the array substrate. Spacers are arranged between the array substrate and the counter-covering substrate at intervals, and comprise a plurality of main spacers. M main spacers are arranged in the unit area of the peripheral area of the display panel, N main spacers are arranged in the unit area of the middle area of the display panel, and the M is larger than the N. Correspondingly, the invention further provides a control method of the display panel and a display device. Pressure borne by each spacer of the periphery area of the display panel can be reduced, and the problem that in the prior art, the spacers on the peripheral area of the display panel are damaged or an orientation layer on the spacers is damaged can be solved.

Description

Technical field [0001] The present invention relates to the field of display technology, and in particular to a display panel, a manufacturing method of the display panel, and a display device. Background technique [0002] In a liquid crystal display device, it usually includes an array substrate, a color filter substrate, and a liquid crystal layer disposed between the two. In order to maintain the stability and uniformity of the thickness of the liquid crystal layer, spacers need to be arranged between the array substrate and the color filter substrate. The object supports the panel structure formed by the array substrate and the color filter substrate. [0003] At present, the commonly used spacers are post spacers, and in order to have sufficient restoring force when the display panel is subjected to external pressure, the post spacers are usually divided into main column spacers and auxiliary column spacers The height of the main columnar spacer is greater than that of the a...

AI Technical Summary

Problems solved by technology

However, in the production process of the display panel, after the array substrate and the color filter substrate are boxed together, when thinning, secondary cutting and other processes are performed, the pressure on the peripheral area of ​​the display panel is greater than that on the middle of the display panel, which may cause the display Each main columnar spacer 1 in the peripheral area of ​​the panel is damaged. In addition, the alignment layer in contact with the main columnar spacer 1 may be damaged, thereby affecting the structure of the liquid crystal layer. At the same time, the main columnar spacer 1 or the above The impurities produced by the damage of the alignment layer may fall off into the liquid crystal layer and affect the display effect
