ABSTRACT OF THE DISCLOSURE This disclosure depicts cathodo-luminescent devices and luminescent panels employing X-Y matrices of such devices as the display elements. The cathodo-luminescent devices are depicted as each comprising a two-section cell containing an ionizable gas at very low pressure. The first section comprises an electron-multiplier serving as a controllable source of free electrons. Free electrons are drawn from the electron- multiplier and accelerated in the second section to high energies whereupon they collide with a light-emissive phosphor screen. Other structures including means for modulating the flow of electrons to the screen are disclosed.
