Problems solved by technology
[0007] (1) The pulse voltage is applied between the two electrodes to burn the slit, resulting in inconsistent position and width of the slit on the electron emission film, and there is a large deviation in the emission characteristics between the electron emission sources
[0008] (2) A pulse voltage is applied between the two electrodes to burn the slit, and there are some high-resistance substances in the middle of the slit, which may cause the failure of the electron emission source.
[0009] In view of the complex process of making electron emission sources in the above-mentioned SED display devices, the manufacturing steps are numerous, and the equipment is relatively expensive, a new method for manufacturing electron emission sources of surface conduction electron emission flat panel display devices is proposed.

Abstract
The invention relates to a manufacture method of a surface-conduction electron-emitting source of an SED (Surface-conduction Electron-emitter Display). The manufacture method is characterized by comprising the following steps of: a. manufacturing a transparent glass substrate; b. selecting a conduction electron-emitting film; c. processing the conduction electron-emitting film onto the transparent glass substrate; d. arranging device electrodes which are in contact with the film at two sides of the conduction electron-emitting film; and e. arranging an illumination beam source at the outer side of the transparent glass substrate without the film. The conduction electron-emitting source provided by the invention forms slits with nanoscale width required by electron emission after respectively illuminated by ultraviolet light or laser with specific wavelength and intensity, and the shapes of the slits are in random arrangement; and by adopting the surface-conduction electron-emitting source provided by the invention, local high-resistivity substances among the slits do not exist, therefore, the disabled probability of the electron-emitting source is reduced.
Description
technical field [0001] The invention relates to the surface conduction electron emission flat panel display device technology, in particular to a manufacturing method of a SED display surface conduction electron emission source. Background technique [0002] With the advent of large-scale flat-screen high-definition televisions and large-screen high-resolution displays for portable computers, flat-panel displays have gradually become the mainstream of displays, and have been extensively researched and developed. Among them, the Surface-conduction Electron-emitter Display (SED) proposed by Japan's Canon Corporation belongs to FED (Field Emission Display), but it has caused a lot of attention in the industry and society due to its high contrast, low power consumption, and fast screen response. focus on. [0003] The imaging principle of SED is similar to the traditional cathode ray tube (CathodeRayTube, CRT). The difference is that SED places the glass substrate coated with p...
