Construction of surface conductive field emission electronic source conductive film

Abstract

The invention discloses a conducting film structure of a surface conduction field emission electron source, namely, a conducting film of an electron source is formed by a multilayer composite film which is formed by a palladium oxide film (PdO) and an amorphous carbon film, the electron transmitting performance of the conducting film can be improved by using the good electron emission stability of the palladium oxide film and the lower effective work function, the large carrier mobility, the high breakdown voltage, the wide forbidden bandwidth and the high heat conduction coefficient of the amorphous carbon film, and consequently, the emission current density and the electron emissivity of the field emission electron source are increased.

Description

Structure of Conductive Film for Surface Conduction Field Emission Electron Source technical field The invention belongs to the field of flat panel display device manufacturing, and relates to a structure of an electron emission source, in particular to a layer structure of a conductive film of a surface conduction electron emission source that can be used in a field emission display device. Background technique Surface-conduction Electron-emitter Display (SED) is an advanced flat panel display device newly developed in recent years. No matter in terms of contrast, gray scale, color and dynamic image display quality, etc., or in terms of power consumption and thickness, SED is better than the current mainstream liquid crystal display (LCD) and plasma display (PDP), and is considered to be the successor The next generation of flat panel display devices after LCD and PDP. SED is a high-vacuum display device. It consists of a front glass substrate, a rear glass substrate, a...

Problems solved by technology

The advantage of the SED using palladium oxide as the conductive film is that the stability of electron emission is good, but the disadvantage is that the emission current density and electron emission rate are low, resulting in low brightness of the SED
