ABSTRACT:
A light emitting diode matrix array is used as the light source of a picture projection system. Each cell of the LED matrix array has an assembly of one or more red, green and blue LEDs with metal lead structures to individually energize these LEDs. The lights emitted from the LED assembly is transmitted through one or more programmable liquid crystal plate or digital micro-mirror device to control the light transmission, and then merged together for projection as a pixel onto a screen.
