Patent ID: 8421710

Claim:
A light source apparatus comprising: a metal substrate; an electrically insulating planarization film formed on the metal substrate; a plurality of reflective metal layers formed on the planarization film; a plurality of LED (light emitting diode) thin films arranged in a matrix having columns extending in a first direction and rows extending in a second direction perpendicular to the first direction, each of the plurality of LED thin films being bonded to a corresponding one of the plurality of reflective metal layers via intermolecular force; a plurality of first wires, each of the plurality of first wires being electrically connected to a corresponding one of first electrodes of the LED thin films; a plurality of second wires, each of the plurality of second wires being electrically connected to a corresponding one of second electrodes of the LED thin films via a corresponding one of the plurality of reflective metal layers; a first driver circuit for selectively electrically driving the LED thin films arranged in the rows via the plurality of first wires; and a second driver circuit for selectively electrically driving the LED thin films arranged in the columns via the plurality of second wires.
