Color Consistency Enhancement of White Light-Emitting Diodes Through Substrate Design

We demonstrate a new kind of substrate structure to enhance the correlated color temperature (CCT) consistency of white light-emitting diodes through controlling the liquid morphology by the wetting theory. Based on this method, the effect of the coating phosphor volume variation on CCT can be effec...
