Abstract
A flat CRT apparatus has a set of vertical scanning deflection electrodes arrayed down one flat inner face of the CRT, spaced apart from an opposing face having a photo-emissive layer formed thereon, and an electron gun for emitting a single flat electron beam or a row of narrow line electron beams into the space between the scanning electrodes and the photo-emissive layer. Vertical scanning of a raster display is executed by scanning voltages sucessively applied to the scanning electrodes, with the deflected electron beams thus obtained being then horizontally swept in common by a horizontal deflection electrode, so that each electron beam is utilized to display a large number of picture elements of each horizontal scanning line of the display picture.
