How To Refurbish LED Display Screens?

To refurbish the LED display screen, the first step is to repair the fault point, then clean the LED display screen, remove surface debris, and start point by point correction. Point by point calibration utilizes optical instruments to collect brightness (or chromaticity) data for each LED display screen. Through calibration software, scientific analysis and calculation are carried out, and the corrected data is written into the control system to achieve uniformity in LED display screen brightness (or chromaticity). After correction, the LED display screen can maintain a brightness difference of 3% and a chromaticity difference of within 0.003. The corrected LED display screen can see a significant improvement effect, although it cannot avoid losing a certain amount of brightness, but compared to blurred screens and blurry screens, it has improved a lot.
