Light-emitting backlight source with non-connected same-recess staggered double-sided cathode chamfer single-tip gating structure

Abstract

The invention discloses a light-emitting backlight source of a non-joint same-recess staggered double-sided cathode chamfer single-tip gating structure, which comprises a vacuum sealing body and a getter accessory element positioned in the vacuum sealing body, and is characterized in that the vacuum sealing body consists of a front hard transparent glass plate, a rear hard transparent glass plateand a narrow glass frame strip; an anode etching film cushion layer, an anode continuous straight silver layer and a thin light-emitting layer are arranged on the front hard transparent glass plate, the anode etching film cushion layer is connected with the anode continuous straight silver layer, and the thin light-emitting layer is manufactured on the anode etching film cushion layer; and the rear hard transparent glass plate is provided with a non-connected same-recess staggered double-sided cathode chamfer single-tip gating structure. The light-emitting backlight source has the advantages of being good in light-emitting uniformity and high in light-emitting brightness.

Second, the electron emission efficiency of the carbon nanotube cathode is relatively low

In the carbon nanotube cathode, only a small number of carbon nanotubes can normally emit electrons, which is not enough to form a large cathode current for a luminescent backlight, and most of the carbon nanotubes do not emit electrons, forming a de facto The failure of the cathode also wastes and takes up valuable carbon nanotube fabrication area
