AUTOEMISSION CELL Russian patent published in 1996 - IPC

FIELD: electronic engineering; fluorescent-display autoemission electron sources. SUBSTANCE: autoemission cell has relatively parallel film anode and cathode with phosphor, and insulating layer, all mounted on common substrate. Emitting edge of cathode is cut into U-shaped teeth to form comb which are unequally spaced from anode and provided with resistors inserted in cathode film break. Film cathode is oval-shaped. EFFECT: improved reliability, service life, and operating stability in case of voltage fluctuations; enlarged functional capabilities. 4 cl, 2 dwg
