ABSTRACT:
A rear-projection display for providing uniform brightness to images projected onto a screen. An auxiliary mirror, which allows a portion of incident light to pass therethrough and reflects another portion of the light, is disposed between a light source and an image display such that only a portion of the light from said light source is incident upon said auxiliary mirror. A main reflection mirror reflects light emitted from the light source and directs the light through an image display. The reflected light from the auxiliary mirror is incident on the main mirror.
