ABSTRACT:
A flat panel color display device is comprised of a two-dimensional array of stacks of colored membranes. Each membrane is comprised of a conductive film sandwiched between colored insulating films and integrated within a pellicle assembly which wends between pairs of adjacent colored fiber electrodes between which membrane stacks are juxtapositioned and around which membranes optionally wrap. Each colored membrane stack together with portions of the adjacent fiber electrodes defines one color pixel produced by the exposed surface colors of the membranes and the fiber electrodes. Any pixel or group of pixels of the display can display any color of the palette. Thin film transistor electronics are provided within a silicon coating on one fiber of each pair. Conductive traces on the pellicle assembly provide power, signal and interconnectivity between fiber electrodes and the pellicle assembly. Pixel color is established in accordance with input signal by supplying a voltage pattern to the membranes whereby they part revealing surfaces of a common color, membranes on either side of the part being repelled from each other and attracted together and to an adjacent fiber electrode. The display is neither self-luminous nor requires a dedicated light source but is viewable under ambient illumination. It's thin format enables picture-on-the-wall color television. In an optional configuration an included power source together with sample-and-hold electronics provides image storage following disconnection from signal and prime power. Reconnection to sources of power and synchronization allows recovery of the stored image as a data stream.
