ABSTRACT:
An electrostatically actuated color video display is disclosed which can be illuminated by backlighting transmitted through the display and by reflected ambient light to have good visibility in both bright daylight and in subdued or dim light. To display full-color dynamically changing images from an electronic video signal the functions of creating the image and of generating color light rays for use in the image are separated. A preferred embodiment employs a pixellated color screen having rectangular cells of alternate red, green, blue and a somewhat opaque white color and a shuttering mask comprising an array of selectively actuatable light-modulating capacitors with black movable electrodes that when retracted are in registration with and present an open light path to individual color screen cells and when extended present a continuous black screen appearance.
