Image apparatus having recessed envelope for placement of electrode |
摘要 |
An image-forming apparatus comprises in a vacuum envelope an electron source including a plurality of electron-emitting devices and an image-forming member including a fluorescent layer and a high voltage anode layer disposed vis-a-vis the electron source. The envelope may preferably have a low resistance electroconductive member electrically connected to the ground by way of a low impedance ground connection line for by-passing large electric current which may occur upon electric discharge between the anode layer and the electron source and can possibly destroy the electron-emitting devices if flowing thereinto by way of the driving wires of the devices. The high voltage anode layer and/or the low resistance electroconductive member is drawn out from the inside of the envelope to a recess formed in the outer surface of the envelope and is electrically connected to external wiring in the recess.
