Problems solved by technology

The disadvantage of this method is that there is one more high-temperature sintering process in the whole process of making the lower substrate. After sintering, it is easy to cause deformation of the glass, which makes the alignment deviation between the various graphics, resulting in inaccurate alignment, and also wastes the sintering furnace. energy

Embodiment Construction

[0008] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0009] see figure 1 , 2, 3, first, on the glass substrate 1 with the address electrode pattern 2, print a white barrier paste with a thickness of 180um-220um and a black barrier paste with a thickness of 20um-50um, and then print it at 130°C-160°C Dried down to form a white barrier layer 3 and a black barrier layer 4, and the total thickness of the white barrier layer 3 and the black barrier layer 4 is equal to the height of the dielectric layer and the barrier layer; see Figure 4 , 5, secondly, sintering the white barrier slurry layer 3 and the black barrier slurry layer 4 at 550°C-570°C; then, paste a layer of acid-resistant and alkali-resistant photosensitive resist on the sintered black barrier layer 4 Dry film or directly print or apply a photosensitive resist film to form a resist layer 5, and then use a barrier master to expose and develop the resis...

Abstract

The manufacture method for lower base in plasma display screen comprises: printing barrier slurry and drying on glass base with addressing electrode graph, then sintering; sticking one layer of acid-resistant un-alkali-resistant photosensitive etch-resistant dry film on sintered barrier layer or direct printing or coating one layer of photosensitive etch-resistant film to form etch-resistant layer; exposing and developing to the etch-resistant layer by barrier master plate to form barrier figure as mask for etching by hydrochloric acid solution according to require height; using alkali solution to peel the etch-resistant layer on top of barrier wall; then, coating red, green and blue fluorescent powder by silk-screen printing method. this invention reduces process and cost.

Description

technical field [0001] The invention belongs to the technical field of flat panel display, and in particular relates to a method for manufacturing a lower substrate of a plasma display screen. Background technique [0002] Color plasma display is a flat panel display that excites red, green, and blue phosphors to emit light through vacuum ultraviolet rays generated by gas discharge. It has the characteristics of light weight, small size, and wide viewing angle. It has strong competition in the current display technology field. force. [0003] Plasma display usually includes a front substrate and a rear substrate. Transparent electrodes, Bus electrodes, transparent media and magnesium oxide protective layers are fabricated on the front substrate, and addressing electrodes, dielectric layers, barrier ribs and phosphors are usually fabricated on the rear substrate. pink. At present, the manufacturing method of barriers mostly adopts the sandblasting method with high efficienc...
