Why does the full-color LED display show chromatic aberration? _Full color LED display manufacturer|Huaze Optoelectronics
The current outdoor full-color LED display can fully cope with harsh outdoor environments such as hot summers, cold winters, sandstorms, and terrible thunderstorms. The advantages of full-color LED displays in all aspects can bring the greatest benefits to businesses. change. But why are there still many full-color LED displays with chromatic aberration? It is worth noting that the inconsistency of the brightness of the full-color LED display is the root cause of the blurred screen. It cannot be corrected with the post-correction equipment, and it can only be achieved during the manufacturing process of the full-color LED display manufacturer. Therefore, if you purchase a screen with inconsistent brightness, please contact your service provider or manufacturer for a solution. The drive element is generally a constant current drive chip, such as MBl5026 and so on. These chips contain 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 a full-color LED display screen to have a brightness error of 25% between pixels. If the LED tube used is not the same grade and type of product, the brightness error will rise to more than 40%. The light-emitting element is the LED light-emitting tube, and it is inevitable that the brightness is inconsistent during the production process. The countermeasure adopted by the full-color LED display manufacturer is to divide it after the production is completed. The smaller the brightness difference between the two adjacent files, the better the consistency, but the lower the yield and the higher the inventory will be more serious. . Therefore, each manufacturer controls the brightness difference between two adjacent gears to about 20%. Huaze Optoelectronics full-color LED display manufacturer reminds everyone: When buying a full-color LED display, you must carefully choose the product brand and business you are buying, and you need to understand the after-sales service of the business. Only in this way can you Guarantee the normal operation of the user's full-color LED display.
