摘要
A high dynamic range projector (HDRP) is configured with at least one spatial light modulator having red, green and blue digital light projector (DPL) chips, a light laser source including red, green and blue (RGB) light laser systems which are operative to illuminate respective DLP chips; and a central processing unit (CPU) coupled to the DLP engines and respective RGB light laser systems, wherein the CPU is operative to determine an optimal average power of each of the RGB light laser systems at a frame rate based on a desired contrast ratio.
