ABSTRACT:
White opaque fixed films in a fixed section are arranged in a two-dimensional matrix. On each fixed film, a cyan transparent film, a magenta transparent film, and a yellow transparent film that constitute a pixel are placed. By electrostatic force, these transparent films are driven and placed under the fixed film of an adjacent pixel, thereby controlling the color of the pixel. To generate electrostatic force, the fixed film and transparent film are provided with electrodes and an insulating film is inserted between these two films. The consecutive reversing of the polarity of both electrodes enables the transparent film to move in parallel with the fixed section. To achieve half tone display and no power consumption in displaying a still picture, an electrostatic mechanical latch mechanism that stops the film still in motion is employed.
