Abstract

The invention provides an electro-static discharge (ESD) testing apparatus and an ESD testing method. The apparatus comprises a testing module (1), a gating module (2) connected with the testing module (1) electrically, and a display module (3) connected with the testing module (1) and the gating module (2) electrically. The testing module (1) consists of a plurality of output channels (from OUT (1) to OUT (N)) connected in parallel and a plurality of testing channels (from TP (1) to TP (M)) connected in parallel; and the multiple parallel output channels (from OUT (1) to OUT (N)) and the multiple parallel testing channels (from TP (1) to TP (M)) are connected in series. Gating of corresponding output channels can be carried out automatically by using the gating module (2) and ESD testing on a testing point can be carried out by the regulated times, so that the testing process is simplified and the testing efficiency is simplified. The display module (3) records and displays positions of the output channels after gating in real time. When the ESD testing is interrupted, an interrupted position can be found rapidly and accurately by using the display module (3) to carry out testing continuously, so that the relay function is realized.

Description

technical field [0001] The invention relates to the technical field of electrostatic discharge testing, in particular to an ESD testing device and an ESD testing method. Background technique [0002] Liquid Crystal Display (LCD) has many advantages such as thin body, power saving, and no radiation, and has been widely used, such as: LCD TV, mobile phone, personal digital assistant (PDA), digital camera, computer screen or Laptop screens, etc., dominate the field of flat panel displays. [0003] Thin Film Transistor Liquid Crystal Display (TFT-LCD) is one of the main types of flat panel display at present. The TFT-LCD controls the input of data signals through a thin film transistor switch, and then controls the screen display. [0004] Specifically, see figure 1 , the main driving principle of TFT-LCD is that the main board of the system is connected with the connector (connector) 100 on the printed circuit board 200 (Printed Circuit Board, PCB) through wires, R / G / B compre...
