Color film substrate and liquid crystal panel

Abstract

The invention discloses a color film substrate and a liquid crystal panel. The color film substrate comprises a base substrate, a black matrix, a transparent conductive film layer and a metal layer; the base substrate comprises a display region and a non-display region; the black matrix and the transparent conductive film layer are oppositely arranged at both sides of the base substrate; the metal layer and the transparent conductive film layer are arranged at the same side; the metal layer is positioned in the non-display region of the base substrate, wherein the metal layer is used for being connected with an earth connection point. In the mode, according to the color film substrate and the liquid crystal panel which are disclosed by the invention, electrostatic charges on the color film substrate can be effectively led out, a better electrostatic shielding effect can be taken, and anti-static electricity capacity of the color film substrate is improved.

Description

Technical field [0001] The present invention relates to the technical field of liquid crystal display, in particular to a color film substrate and a liquid crystal panel. Background technique [0002] Liquid Crystal Display (LCD) is currently the most widely used flat panel display. It has gradually become a wide range of electronic devices such as mobile phones, personal digital assistants, digital cameras, computer screens or laptop screens. It has high resolution Rate color screen monitor. LCD often encounters high voltage electrostatic discharge environment (such as packaging, transportation, touch screen in dry environment, etc.). Electrostatic discharge can cause great damage to electronic components. When the product is not designed for anti-static, the LCD display will be abnormal. The pattern and wiring of the display will be displayed. It can be restored to normal display in a short period of tens of seconds, and it can take several minutes or even tens of minutes to r...

AI Technical Summary

Problems solved by technology

[0004] However, there are certain defects in the prior art method: when the local area of ​​the LCD is subjected to an instantaneous high electrostatic voltage and the ESD charge cannot be exported in time, the transparent conductive film layer will be broken down and damaged, and the edge will break and "blossom" Happening

When ESD charges exist again, the transparent conductive film layer cannot conduct, and ESD charges may damage other film layers in the LCD, or enter the liquid crystal panel (panel) through high-impedance materials (BM, etc.), causing static electricity to remain and affect The size of the electric field of the liquid crystal, resulting in the failure of normal display in a short period of time, or seriously affecting the display effect
