ABSTRACT:
A charge coupled display device for providing a visual image in response to electrical signals applied thereto. The display device preferably utilizes a plurality of charge coupled lines each arranged and controlled so as to operate generally as a shift register, with each of the lines representing one line of the display. Each location in each charge coupled line is caused to contain a charge representative of the image intensity at that point by stepping the charges sequentially along the line from the side, putting in the desired charge for each point in the image. The charge coupled device utilizes buried channels, and upon proper pulsing of the charge coupled device electrodes and the PN junction at the interface of the buried channels, minority carriers are injected from the substrate into the layer of semiconductor material at the surface, which upon recombination with majority carriers, will create an emission at that point proportional to the charge that was stored in the charge coupled device location.
