Abstract

The invention discloses a light-emitting backlight source of an annular vertical separation double-different-surface cathode rear dragging oblique curve gating structure. The source comprises a vacuumsealing 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 plate and a glass narrow frame strip; the front hard transparent glass plate is provided with an anode low-material film block layer, an anode mutual-extension printing line layer anda thin light-emitting layer, the anode low-material film block layer is connected with the anode mutual-extension printing line layer, and the thin light-emitting layer is manufactured on the anode low-material film block layer; and the rear hard transparent glass plate is provided with an annular vertical separation double-different-surface cathode rear dragging oblique curve gating structure. The light-emitting backlight source has the advantages of being excellent in light-emitting intensity uniformity and high in light-emitting brightness.

Description

technical field

[0001] The present invention belongs to the fields of integrated circuit science and technology, nanometer science and technology, microelectronic science and technology, plane display technology, optoelectronic science and technology, vacuum science and technology, and semiconductor science and technology. It relates to the manufacture of a planar light-emitting backlight source, in particular to the manufacture of a planar light-emitting backlight source with a carbon nanotube cathode, in particular to a light-emitting backlight source and its production process. Background technique

[0002] Carbon nanotubes are hollow tubular substances with excellent properties, and are also suitable cathode materials for vacuum components. Due to its extremely high heat resistance, carbon nanotubes can provide cathode electrons for a long time without being burned; due to their good electron emission performance, carbon nanotubes can provide suitable large cathode curr...
