Abstract
A method and an apparatus for displaying information such as an image with an integrated circuit. In one embodiment, a two-dimensional array of infra red light emitting diodes are disposed on a front side of a flip-chip mounted integrated circuit. The infra red light produced by each one of the light emitting diodes travels from the front side of the integrated circuit through the semiconductor substrate to the back side of the integrated circuit. A plurality of up-converting phosphors are patterned on the back side of the integrated circuit to up-convert the infra red light to visible light. In one embodiment, the up-converting phosphors up-convert the infra red light to red, green and blue visible light to produce a color display, viewable from the back side of the flip-chip mounted integrated circuit.
