Patent ID: 8716724

Claim:
An optoelectronic projection device which generates a predefined image during operation, comprising a semiconductor body having an active layer that generates electromagnetic radiation and a radiation exit side and is an imaging element of the projection device, wherein to electrically contact the semiconductor body, a first contact layer and a second contact layer are arranged at a rear side of the semiconductor body, the rear side lying opposite the radiation exit side, and are electrically insulated from one another by a separating layer, partial regions of the first contact layer are led through openings in the second contact layer and through the active layer in a direction toward the radiation exit side, the semiconductor body is structured to form a pattern so that only a part of the semiconductor body is removed in first areas, the first are located between radiation emitting second areas and the pattern is generated during operation of the projection device by the radiation emitting second areas, the second contact layer is in the form of pixels, and at least one part of the predefined image arises as a result of projection of at least part of the pixels and of at least part of the pattern during operation of the projection device.
