ABSTRACT:
An image presentation device (100) with an associated optical light engine includes one or more semiconductor light emitting diodes or other such devices (122, 124, 126) that are combined to provide a source of light to a micro-display panel (150). Light integrators (128), preferably shaped to correspond to the shape of the light emitting devices, are located such that a portion of each terminal is positioned adjacent to or in direct contact with the light emitting surface of the semiconductor dies.
