As a high-tech industry today, led display is an emerging media. With the progress of society, led display is constantly improving in quality and technology, and the rapid development of large-scale integrated circuits and computer technology, so how do we carry out quality technology? What about testing? That is to say, evaluate the quality and technology of the led display. Next, experts from Shenzhen Ai Siwei Optoelectronics Technology Co., Ltd. will tell us how to test and evaluate the quality and technology of LED displays?

Experts instructed to test and evaluate the quality of LED display screens from five aspects:

1. The consistency of the giant led screen display should be good, the brightness of the whole screen should be balanced, and there should be no obvious color blocks.

2. From the point of out of control: the indoor LED display is not more than 3/10000, and the outdoor LED display is not more than 3/10000, and it is discrete.

3. From the appearance point of view: there is no obvious scratch on the outer frame of the led display. The pixel tubes of the outdoor LED display screen should be installed in the same way, without loosening and cracking of the tube shell.

4. In terms of safety, there are no potential safety hazards and leakage current: the ground leakage current should not exceed 3.5mA, and the resistance point strength should not cause insulation breakdown, and the LED display should have warning signs at the fuse and switching power supply.

5. From the structural point of view: the LED display part can be made of steel, aluminum, wood and other materials, and the structure is required to be firm and beautiful.

In summary, the above five points explain how to test and evaluate the quality technology of LED display screens.
