Abstract:
An active matrix display comprising:an active matrix circuit having an array of transistor circuits formed in a first plane, each transistor circuit being connected to a pixel electrode in an array of pixel electrodes of at least 75,000 pixels having an active area of less than 160 mm.sup.2 ;a counterelectrode panel extending in a second plane that is parallel to the first plane, such that the counterelectrode panel receives an applied voltage;a switching circuit connected to the counterelectrode panel that switches the applied voltage to the counterelectrode;a light transmitting material positioned over each pixel electrode such that actuation of a transistor circuit in the array alters an optical transmission property of the light transmitting material;a light source that sequentially flashes to illuminate the optical transmitting material; anda circuit that times actuation of the pixel electrodes to write an image, flashing of the light source to illuminate the image and switching of the applied voltage to the counterelectrode to destroy the image.
