A penetron color display tube including a channel plate electron multiplier disposed between a low energy electron-beam-producing means and a luminescent screen. The screen is formed from repetitive groups of phosphor elements for luminescing in different colors. Each group includes a first phosphor element having a single layer of material for luminescing in a first color, such as blue, and a second phosphor element having two layers of material for luminescing in second and third colors, such as red and green. The channel plate electron multiplier includes a multiplicity of electron-multiplying channels for emitting individual electron beams when the low energy electron beam is directed into the channel's input. At the output of each channel is electrode means for selectively directing the emitted electron beam toward either the first or the second phosphor element in a group, and accelerating means for selectively accelerating the emitted electron beam to a predefined energy level to excite the selected layer in the group.
