The phenomenon of "mosaic" in full color LED display screens has always been a problem that troubles LED display screen manufacturers. Its manifestation is the inconsistency in the brightness of the display surface in different regions. From the perspective of the phenomenon, the "mosaic" phenomenon of LED display screens is manifested as poor brightness of the display surface, that is, poor uniformity. The poor uniformity of LED display screens includes two aspects: poor brightness uniformity and poor chromaticity uniformity.

The fundamental cause of mosaic production is the consistency defects of the lamp tube itself and its use.
