Causes of chromatic aberration failure of LED full-color screen

What is the cause of the color failure of the LED full-color screen? Shenzhen Liansen Optoelectronics has summarized the following points with years of LED display research and development experience:
1. -emitting element
LED full-color display light-emitting elements, namely LED LED Light module-emitting tubes, inconsistent brightness in the production process is inevitable. However, the countermeasure adopted by LED electronic display manufacturers is to divide them after production is completed. The smaller the brightness difference between two adjacent files, the better the consistency, but the more severe the appearance of low yield and high inventory. Therefore, all manufacturers control the brightness difference between two adjacent gears at 20%.
2. Drive components
LED full-color display drive components are usually constant current drive chips, such as MBl5026 and so on. These chips include 16 constant current drive outputs, which can be used to set the current output value. The error of each output of the same chip is controlled within 3%, and the output error of different chips is controlled within 6%. It is normal for the LED full-color display to show a brightness error of 25% between pixels. If the LED tube used is not the same level and type of full-color LED display, the brightness error will rise to more than 40%.
3. The display screen is mixed with materials during the production process, and different batches of dot matrix are used.
This is an global standard which acts as a form of promise that Demo Photoelectric Technology (Wuxi) Co., Ltd. manufatures according to the finest quality standards.
To reduce your production costs, get your and ac led modules from Demo Photoelectric Technology (Wuxi) Co., Ltd.,you will get high quality warranty at favorable price in return. Visit Demo Led Module.
