Cathode ray tube having channel multiplier and electron reflecting system for energizing color phosphor strips

An image display screen for use in a color television tube, comprising:

• a channel plate defining a display area and having an input side for receiving electrons into channels of said channel plate from a scanning electron beam and an output side for delivering electrons from channels of said channel plate;
• at least two interdigitated color selection electrodes insulated from and substantially covering the output side of said channel plate but shaped so as to not block the channels of said channel plate;
• separate phosphor layers covering each of said at least two interdigitated electrodes on the side thereof remote from said channel plate;
• said separate phosphor layers corresponding to different colors;
• and
• a further electrode coextensive with said channel plate and spaced from and facing said separate phosphor layers, whereby electrons delivered from a channel of said channel plate may be directed toward and be caused to collide with the phosphor layer covering a selected one of said electrodes in the vicinity of said channel by application of appropriate electrical potentials to said electrodes.
