Device for reducing power consumption in display system using diffractive optical modulator

摘要

Disclosed herein is a device for reducing power consumption in a display system using a diffractive optical modulator. The device includes a video input unit for receiving video signals, a noise elimination unit for eliminating noise from the video signals and then outputting noise-free video signals when the video signals are input from the video input unit, a drive signal control unit for outputting drive control signals for driving the diffractive optical modulator in response to the video signals input from the noise elimination unit, and a drive integrated circuit for outputting drive signals for driving the diffractive optical modulator and thus generating video images when the drive control signals of the diffractive optical modulator are input from the drive signal control unit.
