Problems solved by technology

[0007] Phosphors are only excited by the inertia of the electrons hitting the metal back film, resulting in poor efficiency; if you want to increase the brightness, you need to apply high voltage to strengthen the force of the electrons
[0008] Since the side viewed by the user is the opposite side of the phosphor excited by electrons, the brightness performance will be poor
[0009] Need greater electron impact force, so the product life is shorter

Embodiment Construction

[0030] Please refer to FIG. 5 , which is a cross-sectional view of the improved structure of the surface conduction electron emission display (SED) of the present invention, which is only part of the structure for illustrative purposes. In Fig. 5, the surface conduction electron emission display 5 comprises a front glass substrate 50, a plurality of transparent electron emission sources 52 arranged on one side of the front glass substrate 50, and a rear glass substrate 54; The metal plate 56 on one side of the rear glass substrate 54, and a plurality of RGB phosphors 58 are evenly distributed on the metal plate 56, and the plurality of transparent electron emission sources 52 are facing the A plurality of RGB phosphors 58 .

[0031] In the present invention, the transparent electron emission source 52 is provided with a very fine covering layer of palladium or palladium oxide on the very close region drawn on the transparent conductor (such as indium tin oxide (ITO)), The cov...

Abstract

The invention relates to an improved structure of a surface conducting electron emission display. The improved structure comprises a front glass base plate; a plurality of transparent electron emission sources arranged at one side of the front glass base plate; a rear glass base plate; a metal plate arranged at one side of the rear glass base plate and a plurality of fluorophors evenly distributed on the metal plate; wherein the transparent electron emission sources are opposite to the fluorophors; therefore the purposes that the brightness of the display is high, the service life is long, no radiation exists and the power is saved are achieved.

Description

technical field [0001] The invention relates to an improved structure of a surface conduction electron emission display (SED), in particular to an improved structure of a surface conduction electron emission display with inverted transparent electrodes. Background technique [0002] Recently, Surface-conduction Electron-emitter Display (SED) display technology has attracted the attention of the industry. Its imaging principle is similar to that of traditional picture tubes, and it also uses phosphor materials that electrons hit the screen to display images ( As shown in Figure 1), while the traditional picture tube (CRT) uses an electron gun to emit electron beams, and then uses control electrodes to guide the direction of the electron beams to excite fluorescent imaging, while the technology of surface conduction electron emission displays (SED) uses electron beams The beam is changed into individual excitation electronic components, and one excitation component corresponds...
