    摘要: A single gun projection cathode ray tube (CRT) which permits the generation of high brightness image output. The crux of the invention is the provision, in the CRT, of an optically reflecting high thermal conductivity metal plate-like member positioned in the path of the electron beam, the surface of the metal plate-like member, which is directed toward both the electron gun and the faceplate of the CRT, being coated with a monochrome phosphor and being cooled by external means. The CRT is capable of producing monochrome images which are reflected by the phosphor-bearing surface of the metal plate-like member toward the faceplate of the CRT and, upon passing through the faceplate, may be projected directly onto a display screen. Alternatively, the CRT can produce projected field sequential color images when it is used either with a synchronized color wheel or with a synchronized liquid crystal shutter color filter interposed between the metal plate-like member of the CRT and the associated display screen.

    摘要: A single gun color cathode ray tube (CRT) having a screen consisting of alternating red, blue and green vertical phosphor strips in groups of three, with strips of conductive or photovoltaic material overlaying each phosphor strip, or placed between adjacent strips. The same color conductive strips are connected in parallel in three arrays, and connected to three individual trigger buses. The conductive lines are connected to a positive bias voltage such that when the electron beam within the CRT strikes a conductive strip, a pulse is generated and fed to the corresponding trigger bus. As the single electron beam scans the screen, trigger pulses are generated in the conductive strips and are fed to a trigger pulse amplifier and then to a multiplexer and used as control signals. The multiplexer in turn gates the color video signals from a remote source, such as a workstation or television set, such that the corresponding video signal for that color is modulating the beam as the electron beam strikes a phosphor strip corresponding to that color.
