全彩色LED显示屏的均匀性包括亮度均匀性和色度均匀性两个方面。
Brightness and chroma are the two aspects of the uniformity problem for the full-color LED display panels.
如果LED亮度和波长不一致，做成大屏幕LED彩色显示屏后，会使观众产生斑点或刺眼的感觉，严重影响LED显示屏的质量，因此必须对LED单管进行分选。
It will affect quality and induce dazzling sight in large color-display if LED's wavelength and light intensity are not measured, so we must achieve auotmatic separation of LED.
有机电致发光器件具存低压驱动、高亮度、高效率以及能实现大面积彩色显示等优点。
