ABSTRACT:
A mixed-color light emitting diode (LED) apparatus may be made by forming a pixellated array of LEDs on a substrate, and then placing phosphors over at least some of the LEDs. The phosphors are chosen to convert light emitted by the LEDs to one or more different colors. The LEDs may be lithographically printed on the substrate, and the phosphors may be lithographically printed on the LEDs.
