Light-emitting backlight source of staggered double-hollow-ring-surface cathode delta-shaped three-arc gating structure

Abstract

The invention discloses a light-emitting backlight source of a staggered double-hollow-ring-surface cathode delta-shaped three-arc gating structure. The light-emitting backlight source comprises a vacuum sealing body and getter accessory elements located in the vacuum sealing body. The vacuum sealing body is composed of a front hard transparent glass plate, a rear hard transparent glass plate anda narrow glass frame strip. An anode bottom electric film layer, an anode curved silver wiring layer and a thin light-emitting layer are arranged on the front hard transparent glass plate, the anode bottom electric film layer is connected with the anode curved silver wiring layer, and the thin light-emitting layer is manufactured on the anode bottom electric film layer; and the staggered double-hollow-ring-surface cathode delta-shaped three-arc gating structure is arranged on the rear hard transparent glass plate. The light-emitting backlight source has advantages that a manufactured structureis reliable and light-emitting gray scale adjustable performance of the light-emitting backlight source is good.
