Process for preparing isolating wall of plasma display

Abstract

A process for preparing the barrier wall of plasma display includes such steps as first generating a number of electrodes at predefined positions on glass substrate, and forming a dielectric layer on each of them, generating several sand blast terminating layers on the dielectric layers corresponding to the said electrodes, and after coating a layer of isolating material, generating a sand resistant layer, sand blasting until the sand blast terminating layer is exposed to form several barrier walls, removing sand resistant layer and sand blast terminating layer, and sintering.

Description

technical field [0001] The present invention relates to a plasma display (plasma display panel; PDP), in particular to a method for manufacturing a barrier wall (rib) of the PDP. Background technique [0002] The plasma display is a flat panel display (FPD) that emits light through gas discharge, and its main features are light, thin, easy to enlarge, and has no viewing angle problem. [0003] Generally, a plasma display is composed of a front panel (front panel) and a rear panel (rear panel). The barrier wall of the plasma display is formed on the rear panel as the interval of the discharge space to define a small discharge space. , and prevent the mixing of RGB three-color phosphors. Below, refer to Figure 1A to Figure 1B , introduces the conventional fabrication method of the barrier rib. [0004] First, please refer to Figure 1A After an address electrode (address electrode) 12 is formed on the surface of the rear glass substrate 10, a dielectric layer 14 is covered...

AI Technical Summary

Problems solved by technology

[0006] In the manufacturing process of the above-mentioned traditional barrier rib 18a, although the dielectric layer 14 below the barrier rib 18a can protect the addressing electrode 12 from being damaged during the sandblasting process, but in order to manufacture the dielectric layer 14, it is necessary to add a High temperature sintering step, thus affecting the good rate of the product

In addition, since the height of the barrier wall 18a is about 100-200 microns, the sandblasting time required to remove unnecessary barrier material with sand is very long, so it is often difficult to uniform the width and profile of the bottom of the barrier wall 18a control, while affecting the efficiency of each discharge cell
