1. A liquid crystal on silicon (LCOS) device, comprising:
a liquid crystal on silicon (LCOS) module with a thermal sensor disposed on a circuit board;
a compensator with a rotatable device disposed on a top of said LCOS module; and
a processing device formed on said circuit board and being responsive to a color-specific response trend of thermal signals to control rotation angles of said compensator according to said thermal signals received from said thermal sensor.
