Patent ID: 7408202

Claim:
A system comprising: a light valve; and an illumination source optically coupled to the light valve, the illumination source having a solid-state light emitting device to emit light of a first color, including a first layer having a surface, and a first, second, and third current spreading segments, wherein each of the first, second, and third current spreading segments includes a rounded oscillating line formed of a series of arced segments, the rounded oscillating lines are substantially parallel to each other and extend from an electrical contact at least partially and non-linearly across the surface of the first layer; and optics optically coupled to the light valve and the solid-state light emitting device and configured to pass the light of the solid-state light emitting device onto the light valve, without using any optical integrator, in a manner such that the light valve is substantially illuminated, in its entirety, with light of the first color, wherein the light valve includes a plurality of pixels and each of the series of arced segments is configured such that a shadow corresponding to each of the arced segments that is imaged onto the light valve has a radius of no greater than forty pixels.
