Plasma display screen barrier wall slurry

Abstract

A plasma display barrier wall pulp is mixed from 80-90 wt per cent photo sensitive pulp 10-20 wt per cent liquid crystal material. Due to liquid crystal being no electric current, its molecule parallel array each other, it capable of being used as switch for stopping light or allowing light passing, said invention adding photosensitive pulp in liquid crystal, to make light transmitting perpendicular to base plate direction in making barrier process, thereby avoiding pulp particle induced photo - scattering phenomena to obtain once smear once completely exposing target.

Description

technical field [0001] The invention belongs to the technical field of gas discharge, and in particular relates to a plasma display barrier slurry. Background technique [0002] Plasma display is a gas discharge light-emitting display device. It produces vacuum ultraviolet light through the discharge of an inert gas in a small space, and irradiates red, green, and blue three primary color phosphors to emit light to achieve color display. The function of the barrier is to To form and maintain the discharge space, prevent the series of electricity and light, so the manufacturing technology of high-precision barrier ribs is essential. In order to make the ultraviolet rays generated by the plasma discharge between the upper and lower electrodes better make the phosphor emit light, it is required that the barrier ribs have a uniform shape and size, a high aspect ratio, and sufficient mechanical strength. [0003] With the development of plasma display technology, there are sever...

Problems solved by technology

However, each method has its disadvantages: the sandblasting method has low material utilization rate, complicated process, and the pollution of sand particles; the screen printing method has problems such as inconsistent alignment and uneven height, and the process is complicated, making it difficult to achieve fineness The photosensitive paste method is to spray the photosensitive paste on the substrate, dry it, expose it through Mask, develop it, and finally form the barrier rib pattern

However, due to the serious light absorption and scattering caused by the particles in the slurry, it is difficult to obtain a thick film with one exposure, so it usually needs to be developed after several exposures, so there are also disadvantages of complex process and difficult alignment
