FIELD-EFFECT EMISSIVE DISPLAY Russian patent published in 2001 - IPC

FIELD: vacuum electronics; flat cathode-luminescent displays. SUBSTANCE: display incorporating insulating substrate and autoemission cells with phosphor-covered electron collectors has these autoemission cells made in the form of oscillatory circuits. At least one autoemission cell is made in the form of parallel oscillatory circuit. At least two autoemission cells differ in resonance frequency. Autoemission cells of same resonance frequency are grouped so that applying control signal at frequency coinciding with resonance frequency of cell ensures display of information image such as alphabet character. EFFECT: enhanced operating reliability; simplified design of addressing system. 3 cl, 1 dwg
