china factory customize high quality test fixture cog test jigs for lcd oled test

• The COG (Chip On Glass) screen testing fixture is a device specifically designed for testing COG structured display screens. COG technology refers to the process of directly binding driver ICs onto glass substrates, which is commonly used in liquid crystal displays (LCDs) and organic light-emitting diode displays (OLEDs) to achieve thinner and more compact screen designs.

• The LCD screen test fixture comprises a test bench, a test circuit board arranged on the test bench, and a clamping mechanism rotationally arranged on the test bench,. During the test, the flip clamping mechanism is used to clamp the test LCD screen and the test circuit board to realize the electrical connection test.

The test method of the LCD screen test fixture includes the following steps:

1 )The clamping plate of the clamping mechanism is turned over and opened on the test bench;

2) The LCD screen to be tested is placed on the test bench, the circuit board of the LCD screen to be tested is correspondingly placed on the test circuit board, and the contacts on the circuit board of the LCD screen to be tested are one by one corresponding to the test points on the test circuit board

3)The clamp plate is turned over and covered on the test bench and pressed on the top of the circuit board of the LCD screen to be tested and the test circuit board;

4)The contact of the circuit board of the LCD screen to be tested and the measuring point on the circuit board to be tested are connected by clamping the clamping plate, and the test signal is transmitted to realize the test work.
