Display panel

Abstract

A display panel comprises a display area and a non-display area. The display panel comprises a pixel array substrate, a color filtering substrate, at least one conductive structure and a display medium. The color filtering substrate comprises a first substrate, a black matrix layer, a color filtering layer and an electrostatic protection layer. The black matrix layer is located on the first substrate and defines a first opening in the display area. The color filtering layer comprises a color filtering pattern located in the first opening. The electrostatic protection layer is located at least between the black matrix layer and a part of the color filtering layer. The conductive structure is located between the pixel array substrate and the color filtering substrate and also located in the non-display area, wherein the electrostatic protection layer is further located between the black matrix layer and the conductive structure. The electrostatic protection layer is electrically connected with the conductive structure.

Description

technical field [0001] The present invention relates to a display panel, and in particular to a display panel with an electrostatic protection layer. Background technique [0002] At present, the market for LCD panels is developing toward high contrast, no grayscale inversion, high brightness, high color saturation, fast response, and wide viewing angle. Fringe Field Switching (FFS) liquid crystal display panel is one of the widely used display panels at present. It has low power consumption, high light transmittance, high brightness, fast response, no color shift and high color reproduction. and other characteristics. [0003] However, in the conventional FFS liquid crystal display panel, since the common electrodes and the pixel electrodes are disposed on the pixel array substrate, when the color filter substrate is subjected to electrostatic discharge (ESD), the display panel will suddenly malfunction. Instable phenomena such as abnormality, if serious, will cause damag...

Problems solved by technology

[0003]However, in the traditional FFS liquid crystal display panel, since the common electrode and the pixel electrode are arranged on the pixel array substrate, when the color filter substrate is subjected to electrostatic discharge ( When electrostatic discharge (ESD) acts, it will cause unstable phenomena such as sudden malfunction of the display panel, and in severe cases, it will cause damage to the electronic components in the electronic product due to the unbearable voltage or current of static electricity

Although it is possible to configure a transparent indium tin oxide (ITO) layer on the surface of the color filter substrate away from the pixel array substrate, and use silver glue to conduct static electricity to improve the ability of the display panel to resist ESD, the above method must Indium tin oxide layer can only be made by flipping the color filter substrate

Moreover, it is necessary to make conductive silver glue by manual dotting, so it is easy to cause problems such as difficult manufacturing process and increased cost.
