Abstract

The invention discloses an electrostatic discharge test system and test method of a display panel. The electrostatic discharge test system of the display panel includes an electrostatic discharge generator, a gating module, and m parallel output channels, wherein the gating module is electrically connected with the electrostatic discharge generator; and the first end of each output channel is connected in series with the electrostatic discharge generator, and the second end of each output channel is connected with a to-be-detected point of the display panel, an electrostatic discharge test isperformed on the to-be-detected point connected with the corresponding second end. With the electrostatic discharge test system and test method of the display panel of the invention adopted, the automated electrostatic discharge test of a plurality of to-be-detected points of the display panel can be realized; the manual operation of relevant staffs can be replaced; manpower can be saved; workingtime can be shortened; and measurement results have high reliability.

Description

technical field [0001] The invention relates to the field of liquid crystal panel display, in particular to an electrostatic discharge testing system and testing method of a display panel. Background technique [0002] TFT-LCD (Thin Film Transistor Liquid Crystal Display, Thin Film Transistor Liquid Crystal Display) has become an important display device in modern video products. The main driving principle of TFT-LCD is that the main board of the system connects the three primary color reduction signals, control signals and power with the connector on the printed circuit board through wires, and after the data is processed by the timing controller on the printed circuit board, the source drive circuit (Source -Chip on Film, S-COF) and gate drive circuit (Gate-Chip on Film, G-COF) are connected to the display area of ​​the display panel, so that the TFT-LCD can obtain the required power and signals. [0003] With the continuous improvement of users' requirements for product ...
