This should be considered from the early stage of the design. Firstly, the quality of the LED lamp core in the screen is better, preferably from Europe, America or Japan. Secondly, the heat dissipation should be solved, and the maximum temperature of the LED lamp core should not exceed the specified value, with a certain margin. Finally, the driver circuit should be given a certain amount of margin, and it is better not to let the LED work in the full power state, leaving the appropriate current / voltage margin helps to extend the life of the LED lamp core.

the other aspects are the packaging technology of LED and the material selection of light transmission layer on the surface. Some materials age very fast, resulting in poor light transmission, and the surface looks similar to the light attenuation of LED. You need to disassemble it to find out what adjustment to use. In addition, if you test it yourself, the screen itself is defective. The LED liquid crystal should be the display ad board or the data line inside, Usually called screen line, LCD screen itself is no problem.
