Problems solved by technology

Due to the exposure technology used in lithography, the size of the barrier is good, the productivity is high, and the mismatch problem is small. However, the low-melting glass powder in the sandblasting barrier slurry is usually Pb-B-Si system, which contains lead oxide. Therefore, It is difficult to avoid pollution to the human body and the environment. The development of lead-free glass paste to replace lead-containing paste has become the development trend of paste for plasma displays.

Abstract

Provided is a barrier rib paste of plasma display panels, which contains lead-free low melting glass powder with percentage by weight of 55-70%, alpha-Al2O3 powder percentage by weight of 5-15%, rutile type TiO2 powder percentage by weight of 1%-10% and organic carriers percentage by weight of 20%-25%. The invention provides a lead-free barrier rib paste which does not contain elements polluting environment aiming at the shortcoming that preparation of barrier ribs by blasting contains lead in paste, which results in pollution upon environment provides a lead-free barrier rib paste which doesnot contain elements polluting environment, thereby meeting requirements of development of environmental protection.

Description

technical field [0001] The invention relates to a medium slurry, in particular to a barrier rib slurry of a plasma display screen. Background technique [0002] Plasma display is a flat panel display device that uses gas discharge to emit light. The barrier structure in the plasma display screen forms tiny discharge cells. A large number of plasma discharge cells are arranged together to form a display screen. When a high voltage is applied between the upper and lower electrodes, the gas in the plasma tube chamber sealed between the two layers of glass generates ultraviolet light, thereby stimulating the red, green, and blue trichromatic phosphors in the barrier chamber to emit visible light, which is determined by the combination of brightness and color changes of these pixels. , producing vivid, bright, clean, sharp images in a variety of grayscales and colors. [0003] In the plasma display screen, the function of the barrier has two points: one is to ensure the discha...
