Display panel with function of antistatic discharging

Abstract

The invention provides a display panel with the function of antistatic discharging. The display panel is characterized in that a first grounding wire avoids a large fan-out area of a first metal layer, so that antistatic discharging caused by the large static electricity during reliability testing of the product is avoided and thus the short-circuit occurrence between the first grounding wire anda fan-out line group of the first metal layer is avoided, so that the antistatic discharging capability of the display panel is improved.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to an anti-static discharge display panel. Background technique [0002] The generation of static electricity is inevitable in industrial production and will cause serious harm. Taking the electronics industry as an example, static electricity mainly causes failure or wrong action of electronic equipment in the form of electrostatic discharge (ESD), causing electromagnetic interference and unstable operation of electronic products, breakdown of integrated circuits and precision electronic components, Or promote the aging of electronic components and reduce the yield of production. [0003] In the product design of liquid crystal display panel (LCD), the protection design of electrostatic discharge is often used. The outermost periphery of the display panel is connected to the ground terminal (GND) of the driver chip (IC) through the ground terminal of the flexible circuit boar...

AI Technical Summary

Problems solved by technology

The bottom of the first ground line 13 has a large-area fan-out line 14 of the first metal layer, and the fan-out line 14 of the first metal layer and the first ground line 13 are only formed by a passivation layer (ILD) (attached (not shown in the figure) barrier, when the reliability test of the product generates a large amount of static electricity, ESD is prone to occur, resulting in a short circuit between the first grounding line 13 and the fan-out line 14 of the first metal layer

Since the fan-out lines 14 of the first metal layer are respectively connected to signal lines such as TP / CT / DMUX / CK / GAS / VGL of the flexible circuit board, ESD will cause a short circuit of these signal lines, thereby causing the display panel to display abnormally.
