Method for producing non-contour barrier wall

Abstract

This invention relates to a processing method for non-contour baffle, which makes baffles contour longitudinally and laterally then prints a necessary thickness layer of baffle material on the contour baffles by a stencil in the same shape of either two of them to be dried, sintered to form a baffle shape in different heights longitudinally or laterally. The method increases the height of the longitudinal baffle to form a baffle in different heights directly by the printing method, which will not break the lateral baffle nor reduce its luminous area to secure its high resolution and brightness.

Description

technical field [0001] The invention relates to a method for manufacturing barrier ribs of a plasma display, in particular to a method for manufacturing barrier ribs with non-equal heights. 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. However, with the increasingly fierce market competition, the requirements for high resolution and high brightness of plasma displays are getting higher and higher. In order to improve the resolution and brightness of the plasma display, the production of its barrier ribs has been developed from the traditional strip barrier ribs to grid-like (or well-shaped) barrier ribs. However, the well-shaped barriers have caused great difficulties in the ex...

Problems solved by technology

However, the well-shaped barriers have caused great difficulty in the exhaust of the plasma display, and the gas is not easy to discharge, which seriously affects the quality of the screen.

In order to solve this problem, the existing methods are as follows: one is to make a groove in the center of the barrier wall in the horizontal direction, so as to facilitate the discharge of gas, but this will reduce the light-emitting area and weaken the brightness, and make a groove in the center of the barrier wall in the horizontal direction It is easy to cause damage to the barrier, which seriously affects the yield rate of PDP; the second is to use a unique photosensitive barrier slurry, through complex multiple exposure and development, to achieve the difference in the height of the vertical and horizontal barriers, so as to achieve a good row. The purpose of gas, but the cost is higher, the process is more complicated, and the photosensitive barrier slurry is unique to Panasonic, and other companies cannot obtain and use it.
