IMAGE DISPLAY DEVICE WITH GRAY SCALES CONTROLLED BY OSCILLATING AND POSITIONING STATES

摘要

An image display device, which uses a spatial light modulator (SLM), comprises a deflective modulation element, which is provided in the SLM, for deflecting illuminating light depending on the deflection state of the element itself, a data converting unit for converting at least N consecutive bits of binary data according to an image signal into non-binary data, and a controlling unit for controlling the deflective modulation element with the non-binary data.
