Problems solved by technology

[0005] 1. In order to prevent optical crosstalk, some areas of the discharge electrodes on the upper substrate do not participate in the discharge, which reduces the space utilization of the discharge surface and is not conducive to the improvement of brightness
[0006] 2. The fluorescent powder in the non-discharge area that does not participate in the discharge is not fully utilized due to the small ultraviolet radiation generated by the discharge.
On the contrary, the phosphor under the discharge area has been bombarded by ions and photons, and the deterioration is serious, which affects the life of the PDP
[0007] 3. Since there is always a part of the space that does not participate in the discharge, the improvement of resolution is limited
This connection method cannot guarantee that the non-discharge gap will not discharge, which is not conducive to improving the contrast

Abstract

An AC surface discharge type plasma display screen with dual discharge spaces is composed of upper and lower base plates. The scanning electrodes and maintaining electrodes on upper base plate are parallelly and alternately arranged. A discharge unit is formed by a scanning electrode, its adjacent two maintaining electrodes and an addressing electrode on the lower base plate. An image frame is displayed by two fields so as to realize the whole screen under the discharged zone in the display process of one frame. Its advantages are high luminous efficient and brightness, low cost of driver, and long service life.

Description

1. Technical field [0001] The invention relates to an AC surface discharge type plasma display screen with double discharge spaces. 2. Background technology [0002] Existing conventional AC surface discharge plasma display screens include three-electrode structure, four-electrode structure and five-electrode structure. In these structures, the structures of the lower substrate are all the same or similar, and the lower substrate includes a lower substrate glass, parallel address electrodes formed on the lower substrate glass, and a lower substrate glass plate provided with the parallel address electrodes. A dielectric layer formed on the dielectric layer, a barrier rib parallel to the address electrodes formed on the dielectric layer for separating adjacent discharge spaces and maintaining the height of the discharge space, and a photochromic coating is applied between the adjacent barrier ribs Phosphor powder; the upper substrate includes an upper substrate glass, a scan ...
