Method for producing upper and lower base plate electrode of plasma display screen

Abstract

This invention provides a manufacturing method for up and down base plate electrodes of a plasma display screen including a glass upper base plate and a glass lower base plate, in which, a transparent electrode, a BUS electrode, a black strip, an upper transparent medium layer and a Mgo medium protection layer are orderly designed on the upper base plate and an ADD electrode, lower medium layer, a baffle and red, green and blue fluorescent powder are orderly set on the lower base plate. The photoetching technology is applied to form the display electrode and the addressing electrode, which intentionally enlarges the pattern of the electrode to let the edges of the electrode connect in short circuit then cuts off unnecessary edges with laser to eliminate the edge effect.

Description

technical field [0001] The invention belongs to the field of gas discharge, and in particular relates to a method for manufacturing upper and lower substrate electrodes of a plasma display screen. Background technique [0002] In the past, screen printing was used to directly form graphics for making electrodes, or photosensitive electrode paste was used to directly form graphics through printing, exposure, and development. However, during the fabrication process of the electrodes, the surrounding edges are slightly thicker than the overall thickness due to printing (ie edge effect), resulting in insufficient exposure of the edges under normal exposure conditions, resulting in insufficient development, and may lead to short circuits between electrodes. At the same time, due to the inconsistent contact between each lead terminal and the shorting rod of the aging machine during aging, the voltage applied to each electrode during aging is inconsistent, and finally the white fie...

Problems solved by technology

However, during the production process of the electrode, the surrounding edges are slightly thicker than the overall thickness due to printing (that is, the edge effect), which leads to insufficient exposure of the edges under normal exposure conditions, resulting in insufficient development, and may cause short circuits between electrodes.

At the same time, due to the inconsistent contact between each lead terminal and the shorting rod of the aging machine during aging, the voltage applied to each electrode during aging is inconsistent, and finally the white field of the display is uneven due to the memory effect of the display.
