Thin film transistor liquid crystal display

Abstract

The invention provides a thin film transistor liquid crystal display which comprises a first polarizer, an array substrate, a colored filter substrate, a second polarizer and conductive glue. The array substrate is located above the first polarizer, the colored filter substrate is opposite to the array substrate, a liquid crystal layer is clamped between the colored filter substrate and the array substrate, the second polarizer is located above the colored filter substrate, the side edge of the second polarizer is cut into a special shape, and the conductive glue is arranged between the second polarizer and the colored filter substrate in a coating mode. The side edge of the second polarizer, the side edge of the conductive glue and the side edge of the colored filter substrate further comprise silver glue which is electrically coupled with the second polarizer. Compared with the prior art, the side edge of the second polarizer is cut into the special shape such as a corrugated shape, so that the contact area of the conductive silver glue and the second polarizer is increased along with increasing of the length of a curve on the side edge of the second polarizer, smaller grounded impedance is obtained, and a more reliable electrostatic discharge path is formed.

Description

technical field [0001] The invention relates to a liquid crystal display technology, in particular to a thin film transistor liquid crystal display. Background technique [0002] The liquid crystal display device mainly includes a color filter substrate, an array substrate, a liquid crystal layer, a frame and a printed circuit board (PCB). Generally, a black matrix and a photoresist are arranged on the color filter substrate, thin film transistors (ThinFilmTransistor, TFT) are arranged on the array substrate, and spacers are arranged in the liquid crystal layer. During the manufacture and use of liquid crystal display devices, it is easy to generate static electricity and accumulate on the color filter substrate. When the static electricity accumulates to a certain extent, an electrostatic field will be generated. This electrostatic field will interfere with the electric field of the liquid crystal molecules inside the liquid crystal panel. The display screen is abnormal. ...

AI Technical Summary

Problems solved by technology

However, when the conductive silver adhesive is broken, this solution often causes poor contact between the polarizer and the ground wire of the array substrate, so that the static electricity on the color filter substrate cannot be discharged in time, and in severe cases, the arrangement of liquid crystal molecules will be affected. effect, resulting in pixel light leakage

In addition, if the contact area between the conductive silver glue and the polarizer is too small, it will easily lead to poor conductivity, or the coating position will cause bubbles on the edge of the upper polarizer, etc.
