Abstract

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