Problems solved by technology

[0008] However, the range of the existing barrier wall 28 structure that can accept ultraviolet radiation is only the left and right side walls, so its luminous brightness is limited; in addition, the traditional elongated barrier wall 28 design is easy to generate ionized gas cross talk of discharge To the phenomenon of adjacent light-emitting regions 162, this will form the interference between the display units (cells), and then affect the display quality of the plasma display 10
[0009] U.S. Patent No. 6376987 discloses a new type of electrode design for an AC plasma display panel, which utilizes a discharge electrode (row electrode) with a continuous body portion at the position of the discharge gap (discharge gap) to avoid the discharge electrode The independent projecting portion (projecting portion) changes the discharge characteristics due to position errors, and can improve the shortcomings of the low discharge efficiency of the traditional linear discharge electrode
However, if an open circuit occurs in the design of the independent discharge electrode, point defects will be generated, resulting in a decline in the pass rate, and the independent discharge electrode requires high alignment accuracy, which may easily cause changes in the discharge characteristics. However, a discharge electrode with a continuous body portion will cause adjacent sub-pixel regions to interact with each other, thereby reducing the operating voltage range.

Abstract

Structure of faceplate includes a back plate, multiple auxiliary pixel areas, a front plate, and multiple maintain poles. Multiple closed interclude wall areas separate multiple auxiliary pixel areas arranged on the back plate in triangular arrangement mode of pixel. Multiple maintain poles including multiple auxiliary poles and multiple extension poles are setup at surface of the front plate faced to back plate. The extension poles are extended along first direction and parallel to each other. Discharging gap is formed in auxiliary pixel area between extended poles from auxiliary poles and adjacent extended poles from maintain poles. There is at least one relevant connection pole to connect each extended pole to adjacent extended pole.

Description

technical field [0001] The invention relates to an AC plasma display panel, in particular to a structure of a discharge electrode and a barrier wall of an AC plasma display panel. Background technique [0002] A plasma display (Plasma Display Panel, referred to as PDP) is a thin display, and its main feature is that it can be a super-sized, ultra-thin screen to save a lot of screen space. The light emitting principle of the plasma display is similar to that of a fluorescent lamp. Inert gas is injected into the vacuum glass tank, and the inert gas is pressurized by voltage to generate a plasma effect and emit ultraviolet rays. At this time, the ultraviolet rays are irradiated on the glass tank wall surface. Fluorescent material, which can make the fluorescent material excite red, green or blue visible light. In this way, the screen of a plasma display is composed of hundreds of thousands of units that can emit light by themselves, and each light-emitting unit contains small ...
