Abstract
A light modulator pixel unit and a method for manufacturing the same are provided. The light modulator pixel unit includes top, movable and bottom electrodes. Under control of a control circuit, the movable electrode may shift to first, second and third positions corresponding to modulations of first, second and third monochromatic lights, respectively. When the movable electrode is at a certain position, the incident light corresponding to the position may be divided into two parts, one is reflected by the top electrode, and the other one may bypass the top electrode and be reflected by the movable electrode. The two parts may interfere destructively. The light modulator pixel unit of the present invention can control monochromatic lights of three special wavelengths by time division, and enable color control and gray control. The unit is applicable in the field of projection display and panel system.
