Abstract

The invention belongs to the technical field of manufacturing field emission displays, and in particular relates to a method for manufacturing a lower substrate of a triple-medium layer of a field emission display. The method comprises the following steps: 1) printing a grid electrode layer and a first light sensitive dielectric layer in turn on a glass substrate; 2) using a mask plate to perform exposure development on the first light sensitive dielectric layer and the grid electrode layer; 3) printing an etching type dielectric layer on the first light sensitive dielectric layer; 4) performing electrode medium co-firing on the first light sensitive dielectric layer, naturally cooling the first light sensitive dielectric layer to the room temperature and then taking out the first light sensitive dielectric layer; 5) printing a second light sensitive dielectric layer, drying the second light sensitive dielectric layer and then printing a cathode electrode layer; 6) using a cathode mask plate to cover the second light sensitive dielectric layer and the cathode electrode layer, and performing the exposure development; 7) performing a second electrode medium co-firing; and 8) using the cathode electrode layer and the second light sensitive dielectric layer as masks, and using a wet method to etch the etching type dielectric layer to finish the process of manufacturing the lower substrate. A pressure resistance test shows that the triple-medium in the method can bear at least 200 volts of voltage and cannot be broken down.

Description

technical field [0001] The invention belongs to the technical field of Field Emission Display, and in particular relates to a method for manufacturing a lower substrate cathode, grid and an insulating medium layer between the cathode and grid of a field emission display. Background technique [0002] Field emission display device (FED), as a new type of display device and display technology, is a flat panel display device whose luminescence principle is closest to that of cathode ray tube (CRT) among flat panel display devices, and is considered to be a real possibility to combine with plasma (PDP) and flat-panel displays that compete with liquid crystal display devices (LCD). However, there are still many technical problems that have not been effectively resolved, which limits the popularization of the application of FED in actual production and life. Among the many technical problems, the most critical is the production of the lower substrate, because the lower substrate ...
