Abstract

The liquid crystal on silicon (LCoS) display includes a polarization beam splitter (PBS), a light source, a LCoS panel and a gain control circuit. The PBS has a first side and a second side. The light source is disposed at the first side of the PBS. The gain control circuit receives brightness values. Each of the brightness values has a coordinate which is based on a coordinate axis extending from the first side of the PBS to the second side. The coordinate of a first brightness value is less than the coordinate of a second brightness value. The gain control circuit determines gains according to the coordinates, and adjusting the brightness values according to the gains, in which the gain of the first brightness value is less than the gain of the second brightness value.
