Abstract
A full-color light-emitting diode (LED) having a red LED die, a blue LED die, and a green LED die. The red LED die serves as a supporting material on which the blue LED die and the green LED die are separately mounted in such a manner that the red LED die is not completely covered to reserve a red-light emitting surface. In this way, the red, blue, and green LED die forms a double-layer full-color LED to facilitate the packaging operation, to ensure a more compact mixture of red, green, and blue lights and to achieve an exact wave-mixing effect for obtaining a full-color light.
