Problems solved by technology

When producing TN-type TFT-LCD displays, as long as there are particles in the box, there is a risk of unstable bright spots, which is caused by the limitation of the design structure of the existing TN-type TFT-LCD displays.
[0005] The existing technical solution to improve the unstable and abnormal bright spots of TN-type TFT-LCD displays is to control the production line of TN-type TFT-LCD displays to prevent the color film substrate and array substrate of the TN-type TFT-LCD There are particles in the memory, but there is a bottleneck in the existing technical solutions: Even if the air cleanliness level of the production line is improved, inspection links are added to the production line, and the production process is improved, it is still impossible to guarantee that all products on the production line are in the state of 0 particles, as long as there are particles in the product , there is a risk of unstable bright spot anomalies

Abstract

The invention relates to a method for improving the unstable bright spot abnormity of a TN type TFT-LCD. The method comprises the step of coating a transparent electrode layer of a color film substrate of the TN type TFT-LCD with a polystyrene insulating layer.

Description

technical field [0001] The invention relates to the field of liquid crystal displays, in particular to a method for improving unstable and abnormal bright spots of a TN-type TFT-LCD display. Background technique [0002] A thin film transistor liquid crystal display (Thin Film Transistor Liquid Crystal Display, TFT-LCD) is a common flat panel display device at present, and is widely used. Usually, a TFT-LCD display is mainly composed of a color filter substrate (Color Filter, CF) and an array substrate sandwiching a liquid crystal. The circuit of the array substrate controls the deflection of the liquid crystal in the box, so that the light from the backlight is selectively transmitted for display work. . When the TFT-LCD display is powered on, the upper and lower voltages drive the liquid crystal in the cell to twist and deflect, forming a light-blocking and transparent controllable structure. The production process of the TFT-LCD display is to make the array substrate an...
