Problems solved by technology

However, the disadvantage of this process is that it cannot form high-precision electrode patterns, and with the increase of printing times, the screen is prone to inelastic deformation, so that the electrode patterns cannot meet the precision requirements.
However, such molecular branching is complex, difficult to synthesize, and relatively expensive to produce.

Abstract

The invention provides electrode slurry for a plasma display. The electrode slurry comprises an organic matter component, silver powder and low melting-point glass powder, wherein the organic matter component comprises a copolymer skeleton of methyl methacrylate and methacrylic acid; part of carboxyl of the copolymer skeleton have a structure of unsaturated double bond by introducing propylen acyloxy; and all the rest of carboxyl of the copolymer skeleton is neutralized by aqua ammonia. The invention also provides application of the electrode slurry in manufacturing the plasma display. The electrode slurry formed by the invention can be stably stored for a long time and can develop by using pure water.

Description

technical field [0001] The invention relates to an electrode paste for a plasma display and the application of the electrode paste in the manufacture of a plasma display. The electrode slurry formed by the invention can be stored stably for a long time, and can be developed with pure water. Background technique [0002] In recent years, flat panel display technology has become increasingly mature. Large size, high definition and low power consumption are the development direction of flat panel displays. In particular, plasma flat panel displays have gradually become the trend of large-size flat panel displays due to their characteristics of high brightness, high contrast ratio, low cost, and ease of large-scale. The plasma display is mainly composed of two glass substrates, the middle is filled with Penning gas, and there are red, green and blue three-color phosphors in each grid-shaped display unit. There are transparent ITO electrodes on the front substrate, and there a...
