Application of photo sensitive pastes for PDP

Abstract

Although many kinds of thick film pastes are used at present for plasma display panels (PDPs), photosensitive pastes are often used instead of conventional printing methods due to the large size and finer patterning of PDPs. The characteristics of photosensitive paste, however, change depending on each of the drying, exposure, development and firing conditions. It is thus essential to examine the particular forming conditions required to obtain a stable patterned film. In this paper, we found the appropriate forming conditions by researching failure modes at the development and firing stages using photosensitive silver paste and black stripe paste. We also compared photosensitive pastes in terms of patterning efficiency with the conventional printing method, and studied advantages and disadvantages when applied to actual PDPs.
