摘要： Additional control flexibilities to generate more gray scales for an image display system is achieved by controlling the intensity distribution of the light projection from a light source to a deflecting mirror to further coordinate with the control of the intermediate states of the deflecting mirror. The control light source intensity distribution can provide incident light with wide varieties of intensity distributions including non-uniform, symmetrical and non-symmetrical, different distributions of polarizations, various cross sectional shapes of the incident lights and other combinations of all of the above variations. More stable and better control of gray scale control is also achieved by optimizing the intensity distributions of the incident light to produce the best visual effects of the image display.

摘要： A micromirror device, which makes an image display with digital image data, comprises pixel elements which are arranged in the form of a matrix and each of which modulates incident light by using an ON state for deflecting incident light to projection optics, an OFF state for deflecting incident light to a direction different from the projection optics, and an oscillation state where a mirror oscillates between the ON and the OFF state, and a timing controller for performing a timing control for loading the image data into the pixel elements arranged in the form of the matrix. Each of the pixel elements has a mirror, and at least one memory cell. The pixel elements arranged in the form of the matrix are grouped into a plurality of subsets. The timing controller performs a timing control for loading the image data at independent timing for each of the plurality of subsets.
