  • OPTICAL MODULATORS INCLUDING INCORPORATED INTO MOBILE TERMINAL PROJECTOR
    Publication number: 20110085092
    Abstract: A mobile terminal includes an optical modulation projector. The mobile terminal also includes a control system, a projection control unit, and an optical modulation system. The control system outputs a projection control signal and image data. The projection control unit receives the image data from the control system, and generates and outputs a drive control signal depending on the image data received. The optical modulation system generates and modulates light and generates an image in response to the drive control signal and then scans the image for projecting onto a screen.

  • APPARATUS AND METHOD FOR ADJUSTING COLOR CHARACTERISTICS OF DISPLAY SYSTEM USING DIFFRACTIVE OPTICAL MODULATOR
    Publication number: 20080024528
    Abstract: The present invention relates to an apparatus and method for adjusting the color characteristics of a display system using a diffractive optical modulator, which can respond to a user's request to vary color characteristics so as to actively respond to variation in the brightness of external light, etc., and can adjust the overall brightness of an image while maintaining white balance without incurring the loss of gray levels.
