Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to an electric propeller flat panel display (PDP), and a farewell to the address electrode structure ... the writing and speed of a light-emitting unit Don't talk about [prior art]

Due to the rapid development of multimedia, users have increasingly demanded the surrounding sound and light equipment. The cathode ray tube or Cathode Ray Tube (CRT) type display commonly used in the past is

In the era of lightness, thinness, shortness, and smallness, it is no longer enough. In recent years, many flat-panel display technologies have been developed, such as liquid crystal displays (LCDs) and plasma flat-panel displays ( Plasma Display Panel (PDP), and Field Em1SS100n Display (FED), have gradually become the main focus of future displays. Among them, the plasma flat-panel display (PDp) is used as a full-color display device, which has a large display area, especially for large-sized display panels, or outdoor display panels. This is because pDp has a high diurnal quality = :, which is derived from its self-emission form of light with a wide viewing angle and high-speed response. And because the production process is relatively simple, it is suitable for large-scale display

The 4 items are produced by the gas generation of ultraviolet rays, which stimulates the phosphor to emit light. Depending on the discharge mode of the PDP, there are two types of color PDP knives: alternating current (AC) and direct current (DC). In the AC type PDP 589652 V. Description of the Invention (2), the electrode is covered with a protective layer, which makes the AC type pDp have a longer service life and a higher display brightness. Therefore, in terms of display effect, efficiency, and service life, AC-type acids are generally better than DC-type capacitors. 4 3 ΐ 3 Lightning type: PV uses a three-electrode structure (including a common electrode, a scanning electrode) and an address electrode. The 1-electrode structure is an electric form, and is switched and held by applying a voltage to the address electrode. In particular, the two-view η "electrode" system formed on the image display side is composed of a transparent electrode. Through the use of a transparent non-transparent electrode on the === electrode, 半导体 二 ιτ = "transparent electrode material is a semiconductor, typically made of indium tin compared to the 'lightning selection of the transparent electrode' ^ is a plus / /, Day and Girl 6 are relatively low, so they must be transparent.

At this time, ions = the electrons of the rolled body are accelerated 'and ionized into high-speed neutral particles. The neutral particles are generated into vacuum ultraviolet rays and the discharge gas becomes electrical Paste. However, in the traditional structure, the design is designed to avoid the electric shock of the address. The shape is designed to be the same width, and ^} The load on the writing side is too large, and the electrode width must be made;;, not too wide, This causes the writing speed too], ίΚ; the wire ... can withstand a smaller current, a higher probability of disconnection: as early as possible

[Summary of the invention The design of the main wire of the present invention In the discharge of another element of the present invention, because the addressing electric product is large, and the large load is too large, the present invention can also provide a design, that is, a wire and only this phase It forms a pole, which has two adjacent faces only near the light emitting single plus the writing speed, which can avoid the occurrence of a local area on the writing side where two wires are used, and the abutment of the two poles The only purpose is to provide a kind of addressing electricity, and thus the current resistance of the electrode. One purpose is to provide an addressing electrode that connects two wires in the center, except that the electrode only maintains a small area in the area approaching the X electrode and the γ electrode. One purpose is to provide an address electrode to avoid the occurrence of disconnection. A high-efficiency addressing electrode structure. Each addressing electrode includes two regions that are close to the X-electrode and Y-electrical connection areas of the light-emitting unit.
