Due to the characteristics of LED light-emitting chips and the manufacturing process, the uniformity of LED screens has always been a problem that is difficult to solve in the industry; moreover, due to the discrete type of chip aging, many of them have been used for two, three years, or even half a year. The LED display shows serious spots, color blocks, mosaics and other "fuzzy" phenomena.

What kind of LED display can be refurbished?

Of course, not all LED screens can be refurbished by point-by-point correction. For example, large areas of dead lights, power failures and other problems caused the screen to fail to light up normally. If you encounter those problems, you must first fix all the fault points. Only then can the old screen be refurbished.

How to refurbish the LED display?

To refurbish the old screen, it is necessary to repair the fault point first, clean the entire screen to ensure that the LED display is kept in a good state, and then you can start to do point-by-point calibration. Point-by-point correction is to use optical instruments to collect the brightness (or chromaticity) data of each lamp of the LED display, scientifically analyze and calculate it through the correction software, and write the corrected data into the control system to achieve the brightness of the LED display. (Chromaticity) The process of unification.
