V. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to an auxiliary electrode for a plasma flat panel display, and more particularly to an auxiliary electrode for improving the writing speed of a plasma flat panel display.先前 [Previous technology] With the rapid development of multimedia technology, users have increasingly higher requirements for peripheral sound and light equipment. The traditional cathode ray tube (CRT) type display, due to its large size, has gradually fallen short of demand in the era of being light, thin, short and small. Therefore, many flat panel display technologies have been developed successively, such as Liquid Crystal Display (LCD), Plasma Display Panel (Plasma Display Panel, PDP), and field emission display ^ (Field Emission Display 'FED ) 'Has gradually become the mainstream of the future. Among them, plasma flat-panel display (PDP) has attracted great attention as a full-color display device, which has a large-sized display surface, which is particularly useful for large-sized televisions or outdoor display boards. This is because pDp has a high-quality display capability ' source, its self-emissive shape of light with a wide viewing angle <,-, and high-speed response. And because the production process is relatively simple, it is suitable for increasing the size. In color PDP, ultraviolet light (uit

1230964 V. Description of the invention (2) The discharge mode of PDP. Color PDP can be simply divided into two types: alternating current type (AC) and direct current type (DC). The AC-type PDP is covered with a protective layer on the electrodes, so that the AC-type PDP has a longer operating life and also has a higher display blackness. In terms of display effect, luminous efficiency and service life, AC type is also better than DC type PDP, so it is widely used by pDP manufacturers. Generally, a three-electrode structure is used in an AC-type PDP, including a common electrode, a scan electrode, and an address electrode. The three-electrode structure constitutes surface discharge, electricity, and electricity. By applying a voltage to the write electrode, switching or electrical maintenance is performed. Traditionally, the common electrode and the scanning electrode of the substrate on the side where the image is displayed are transmitted through visible light. At each transparent electrode = H there are-or two small non-transparent electrodes' commonly called (jus Electrode).
