Abstract

FIELD: information displaying devices. SUBSTANCE: device has vacuum housing, controlled emitter of electrons and anode which is covered with current-conducting layer, for example, with aluminum, and over it with luminophor. Area of cur-conducting layer covers only part of anode. Another part of anode which is not covered with luminophor is shaped as grid which holes embraces islands of luminophor. Device may be used in design of middle-voltage cathode- luminescent light sources as well as aggregated very-large color TV screens and other information systems which use such light sources. EFFECT: increased efficiency.

Изобретение относится к информационной технике и может быть использовано для создания высокоэффективных средневольтовых катодолюминесцентных светоизлучателей и на их основе наборных телевизионных цветных экранов-гигантов, а также других информационных систем. Сущность изобретения заключается в том, что в катодолюминесцентном светоизлучателе, содержащем в вакуумной оболочке управляемый эмиттер электронов и анод, покрытый токопроводящим слоем, например алюминием, а поверх него люминофором, площадь токопроводящего слоя на аноде покрыта люминофором частично, причем другая часть площади, не покрытая люминофором, выполнена в виде сетки, охватывающей своими окнами ячеек островки люминофора.The invention relates to information technology and can be used to create high-performance medium-voltage cathodoluminescent light emitters and based on them typesetting television color giant screens, as well as other information systems. The essence of the invention lies in the fact that in a cathodoluminescent light emitter containing a controlled electron emitter and an anode in a vacuum sheath, covered with a conductive layer, for example aluminum, and above it with a phosphor, the area of the conductive layer on the anode is partially covered by the phosphor, and the other part of the area not covered by the phosphor , made in the form of a grid, covering its windows of the cells of the phosphor islands.
