Problems solved by technology

[0009] In view of this, in order to solve the above-mentioned problems, the main purpose of the present invention is to configure a pumping and filling buffer layer between the display area and the vent hole, so that the impurities generated during the pumping-filling or sealing the tube are concentrated Between the pumping and filling buffer layer and the sealing wall, an adsorption layer is used to absorb it, thereby preventing impurities from causing abnormal discharge characteristics of the plasma display unit, and preventing uneven image quality in local areas of the plasma display

Embodiment Construction

[0027] The plasma display device with uniform discharge characteristics of the present invention is characterized in that an air suction and filling buffer layer is formed, and the air suction and filling buffer layer is disposed between the display area and the vent holes of the second substrate, and An adsorption layer is arranged on the first substrate. When the relationship between the pumping and filling buffer layer and the adsorption layer conforms to the structure of the plasma display device of the present invention, it can be effectively used in the manufacturing process of the plasma display device. The impurity generated in the process of pumping, filling and sealing the tube is concentrated and adsorbed outside the display area to maintain the normal operation of the plasma display unit in the plasma display device. Hereinafter, the plasma display device with uniform discharge characteristics according to the present invention will be described in detail with referenc...

Abstract

The invention discloses a plasma display device with uniform discharging property, mainly setting a gas exhausting / filling buffer layer between the display area and the venthole, which makes impurities produced during gas exhausting / filling or tube sealing course collected between the buffer layer and the sealed wall, and using absorption layer to absorb these impurities, further avoiding them from resulting in abnormality of discharging property of the plasma display unit, so as to prevent the phenomenon of nonuniform picture quality in its partial areas.

Description

Technical field [0001] The present invention relates to a plasma display device, in particular to design a plasma display device with uniform discharge characteristics. Background technique [0002] In recent years, various new flat panel displays (FPD) have been continuously developed and designed, such as liquid crystal displays (LCD), organic light emitting diodes (OLED), and plasma displays. The trend to replace the traditional cathode ray tube (CRT). Among them, a plasma display is a flat-panel display that generates light by gas discharge, and its biggest feature is that it is light, thin, easy to enlarge, and has no viewing angle problems. [0003] The plasma display panel mainly uses the method of accumulating electric charge by the electrode discharge to display the picture. Because of its large screen, high capacity and the ability to display full-color images, the plasma display panel technology has gradually been studied and The development of a large flat display pan...
