摘要： A single gun (10) color cathode ray tube (CRT) having a screen consisting of alternating red, blue and green vertical phosphor strips (34, 36, 38) in groups of three, with strips of conductive or photovoltaic material (16, 22, 28) overlaying each phosphor strip, or placed between adjacent phosphor strips. The 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 (60) and then to a multiplexer (66) 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.
