DEFORMABLE MICROMIRROR DEVICE

摘要

A micromirror device, which makes an image display with digital image data, comprises pixel elements each of which makes pulse width modulation for incident light depending on the deflection state of light and which are arranged in the form of a matrix. Each of the pixel elements has a mirror, and at least one memory cell comprising a transistor and a capacitor. In such a micromirror device, the total value of the propagation delay time of a ROW line, which connects all of transistors of memory cells arranged successively in a ROW direction, and the switching time of each transistor is smaller than the driving interval of the ROW line driven in the minimum display duration of the micromirror device.
