Embodiment 1

[0018] figure 2 A schematic longitudinal sectional view of the structure of an AC gas discharge display screen according to an embodiment of the present invention is shown. Such as figure 2 As shown, the AC gas discharge display screen includes an upper substrate 201 and a lower substrate 202. The upper substrate 201 includes: a sustain electrode X 207 and a scan electrode Y 208. In the above AC gas discharge display screen, the scan electrode Y 208 and the adjacent The two sustain electrodes X 207 form a discharge gap, and the sustain electrodes X 207 are disposed on the top of the barrier rib 203 and directly above the barrier rib 203 . Wherein, the barrier ribs 203 are disposed on the lower substrate 202 , the lower substrate 202 further includes a lower dielectric 204 , and the upper substrate 201 further includes an upper dielectric 205 and a dielectric protection film 206 .

Embodiment 2

[0027] Figure 4 It shows a schematic longitudinal sectional view of the structure of an AC gas discharge display screen according to a preferred embodiment of the present invention. Such as Figure 4 As shown, the difference between Embodiment 2 and Embodiment 1 lies in that the sustain electrode X 207 in Embodiment 2 has a larger cross-sectional width and has a light-transmitting hole. The use of the sustain electrode X 207 with a light-transmitting hole is also to overcome the problem that when the bus electrode is too thin, it is easy to cause an increase in resistance, and the bus electrode is too thick to cause a decrease in light efficiency. When the width is large, the light effect will not be reduced. Figure 5 shows a top view of sustain electrode X 207, as Figure 5 As shown, there are a plurality of light-transmitting holes on the sustain electrode X 207 .

[0028] From the above description, it can be seen that the above embodiments of the present invention ha...

Abstract

The invention provides an alternating current gas discharge display screen. The display screen comprises an upper substrate and a lower substrate, wherein the upper substrate comprises sustain electrodes X and a scanning electrode Y. The display screen is characterized in that the scanning electrode Y and the two adjacent sustain electrodes X form a discharge gap; and the sustain electrodes X arearranged on the top of a barrier and is positioned over the barrier. The display screen reduces the working procedures for manufacturing transparent electrodes, and reduces the cost; and the sustain electrodes have smaller sectional areas, or are provided with loopholes, which improves the light transmission degree and light efficiency.

Description

technical field [0001] The invention relates to the field of manufacturing color display screens, in particular to an AC gas discharge display screen. Background technique [0002] In the design and manufacture of existing plasma display screens, the number of sustain electrodes X and scan electrodes Y in the XX-YY electrode structure is usually designed to be the same, and the electrode pairs of adjacent units are arranged according to X-XY-YX-XY-Y Arranged and paired, and each electrode is a double-layer electrode composed of a transparent electrode containing ITO (Indium Tin Oxides, indium tin oxide) and a bus (BUS) electrode. The schematic diagram of its longitudinal section is shown in figure 1 shown. [0003] In the prior art, because the electrode adopts a double-layer electrode structure composed of transparent electrodes and BUS electrodes, the manufacturing process and cost are increased, and the manufacturing process requirements for the BUS electrodes are relati...
