Display panel and making method and display device thereof

Abstract

The invention discloses a display panel and a making method and display device thereof. The problems that in the prior art, flicker, green images and the like occur when static electricity is eliminated are avoided, and the display effect and the product yield are improved. The display panel comprises an array substrate and a color film substrate which are arranged oppositely, the array substrate comprises a display area and a peripheral lead area, and the peripheral lead area comprises a grounding line; the color film substrate comprises a transparent conducting layer dorsad facing the side of the array substrate, the display panel further comprises a conductive adhesive arranged between the array substrate and the color film substrate, the orthographic projection of the conductive adhesive on the array substrate is located in the peripheral lead area, and the conductive adhesive is connected with the grounding line; the color film substrate further comprises one ore more connection holes which penetrate through the color film substrate and are formed in an area corresponding to the peripheral lead area of the array substrate, and the transparent conductive layer is connected with the conductive adhesive through the connection holes.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] Thin Film Transistor Liquid Crystal Display (TFT-LCD) is a commonly used flat-panel display at present. Liquid crystal display panels are widely used in modern digital information equipment due to their small size, low power consumption, no radiation, and high resolution. . [0003] In the production process of TFT-LCD, due to the reasons of equipment and personnel, static electricity cannot be completely avoided. Generally speaking, a layer of transparent conductive layer is sputtered on the back of the color filter substrate to eliminate static electricity. The role of static electricity. But so far, how to introduce the static electricity on the ITO conductive layer to the grounding end, each manufacturer adopts different methods. At present, the most common way is ...

AI Technical Summary

Problems solved by technology

[0005] However, this silver-coated glue conduction method has the following defects: First, due to the nature of the silver glue itself, it is very easy to oxidize, corrode, and even fall off, which leads to the disconnection between the transparent conductive layer on the back of the color filter substrate and the array substrate. The virtual connection or even disconnection between the wires will cause the static electricity on the back of the color film substrate to be eliminated, and obvious defects such as flickering will occur, which will affect the display effect and product yield. Secondly, due to the strong fluidity of the silver glue, it is easy to penetrate into the color film The film substrate and the array substrate are connected to other parts, resulting in defects, such as: silver glue penetrates between the color filter substrate and the array substrate, causing the black matrix to connect the transparent conductive layer on the back of the color filter substrate and the grounding wiring of the array substrate , so that the induced potential of the black matrix is ​​unbalanced, causing the periphery of the pixel to shine, and the macroscopic manifestation is the bad greenness of the screen.

[0006] To sum up, when the existing technology eliminates static electricity on the display panel, flickering, greenish screen and other defects will occur, which will affect the display effect and product yield.
