Problems solved by technology

[0006] In view of this, in order to solve the above problems, the main purpose of the present invention is to utilize the adsorption layer adsorption to concentrate on the impure substances near the vent hole and in the air extraction-filling pipe during the air extraction process, so as to avoid improper control of the air extraction-baking steps. Or the impure substances remaining in the pores of the air extraction-gas filling pipe enter the display area through the subsequent gas filling or sealing steps to cause abnormal discharge characteristics of the plasma display unit, so as to further prevent the local area map of the plasma display device from appearing. uneven image quality

Embodiment Construction

[0038]The feature of the panel structure of the plasma display device of the present invention, which improves the discharge characteristics of the plasma display unit, is that an adsorption layer is formed in the area near the vent hole of the substrate and (or) the inner side of the air extraction-filling pipe. During the gas-filling and sealing steps, the impurity generated in the process of forming the display area, pumping-filling and sealing can be effectively concentrated and adsorbed outside the display area to keep the plasma The plasma display unit in the display unit is functioning normally.

[0039] Hereinafter, the panel structure of the plasma display device capable of improving the discharge characteristics of the plasma display unit of the present invention will be described in detail with reference to the drawings and taking the rear substrate of the plasma display device as an example.

[0040] First, see Figure 2. This figure shows a preferred embodiment of...

Abstract

Using adsorption layer to adsorb impurity substance centralized near venthole and inside sucking-filling gas pipe is main purpose of the invention, in order to prevent the said impurity substance from reentering into display area to create abnormal discharging characteristic caused by improper subsequent steps so as to guarantee even image quality.

Description

technical field [0001] The invention relates to a structure of a plasma display device, in particular to a structure of a plasma display device which improves the discharge characteristics of a plasma display unit. Background technique [0002] In recent years, various new flat panel displays (FPDs), such as liquid crystal displays (LCD), organic light emitting diodes (OLEDs) and plasma displays (plasma display panels, PDP), and there is a tendency to gradually replace the traditional cathode ray tube (cathode ray tube, CRT). Among them, the plasma display is a flat-panel display that emits light by means of gas discharge, and its biggest feature is that it is light, thin, easy to enlarge and has no viewing angle problem. [0003] Please refer to FIGS. 1A to 1C , which illustrate the packaging process of a conventional plasma display device. As shown in FIG. 1A, after the front substrate 14 and the rear substrate 12 of the plasma display device are assembled with an adhesi...
