Abstract

The invention provides a field emission display device, which includes an anode structure and a cathode structure oppositely arranged. The anode structure includes an anode substrate, an anode layer, a plurality of dielectric patterns and a plurality of light emitting patterns. The cathode structure includes a cathode substrate facing the anode substrate, a plurality of cathode patterns and a plurality of field emission sources, wherein each field emission source corresponds to each light emitting pattern of the anode structure. In the field emission display proposed by the present invention, the dielectric pattern in the anode structure can cause the distortion of the potential line, so that the local electric field at the edge of the dielectric pattern can be enhanced to attract electrons emitted by the field emission source, so the uniformity of electron emission can be effectively improved . In addition, because the invention has a simplified cathode structure, the field emission source can be prevented from being damaged during the manufacturing process.

Description

technical field [0001] The invention relates to a field emission display, in particular to a field emission display which can improve the uniformity of electron emission and prevent the field emission source from being damaged during the manufacturing process. [0002] Background technique [0003] Field emission display is the next-generation emerging technology with the most development potential after cathode ray tube display and liquid crystal display. Compared with the existing display technology, the field emission display has the advantages of low driving voltage, no viewing angle limitation, wide operating temperature range, high brightness, high contrast and color saturation, etc., especially the carbon nanotube field emission display, which has become more and more popular in recent years. more attention. [0004] [0005] Generally speaking, a field emission display includes an anode substrate coated with a fluorescent material and a cathode substrate provided ...
