THIN-PANEL PICTURE DISPLAY DEVICE

摘要

Picture display device of the thin-panel type, with a luminescent screen (1), electron source means and an addressing system (100) arranged between these means and the screen. Electrons are directed towards desired locations on the luminescent screen by means of the addressing system. A spacer plate (101) of electrically insulating material, with apertures for passing the electrons, is present between the addressing system and the screen. The spacer plate consists of a material having an electrical resistance R (in OMEGA cm) which complies with the requirement log R (250 DEG C) >/= 8.
