Light emitting diode capable of generating different light colors over single wafer

Abstract

A wafer substrate, a light emitting diode (LED) light-emitting layer, a circuit layer and an excitation material layer are included. The LED light-emitting layer includes at least two light-emitting regions, independently distinguished. The circuit layer includes at least two circuit structures that correspond to the at least two light-emitting regions in quantity and are independently controlled. The excitation material layer includes at least one photo-luminescence material, at least one of the at least two light-emitting regions is provided with different photo-luminescence materials, and at least one of the at least two light-emitting regions is not provided with the photo-luminescence material. Accordingly, in the present invention, at least two light colors can be formed over a single wafer substrate through the at least two independently-controlled circuit structures and providing the different photo-luminescence materials.
