Abstract:
A vacuum fluorescent display is disclosed having a grid plate substantially coplanar with the anode and which is controllable with conventional metal oxide semiconductor devices. Each digit of the display includes a segmented anode structure substantially surrounded by a control electrode or grid plate. At least one cathode is disposed adjacent the anode segments and control electrode such that the distance between the cathode and the control electrode is less than the distance between the cathode and any of the anode segments. Utilizing such a structure, a voltage on the order of about -5 volts on the control electrode is effective to cut off luminescence from any of the anode segments of that digit.
Abstract:
A display device includes color filters and electronically aligned photo-emissive elements. The display device is achieved with a matrix of pixels. Each pixel includes a plurality of sub-pixels that are organized within the pixel in one or two directions. Each sub-pixel includes a color filter arranged facing a plurality of photo-emissive elements, an opaque area separating the color filters. In each of the organization directions of the pixel, the photo-emissive elements have a repetition pitch that is two times smaller than the pitch of the color filters. The size of each color filter is smaller than or equal to the size of the photo-emissive element in the organization direction. The display device includes a supply control circuit of the photo-emissive elements that selects the photo-emissive elements situated facing the color filter of each pixel.
