Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] As shown in the figure, a method for improving the bonding alignment accuracy of a shadow mask type plasma display screen includes the following steps:

[0028] (a). When binding the shadow mask plasma display screen, set the temperature of the pressure head of the automatic alignment binding machine to ensure that the actual temperature of the pressure head is 200℃≥T c ≥180°C, 200°C and 180°C are the limit temperature for binding, 200°C is the upper limit temperature for binding, and 180°C is the lower limit temperature for binding;

[0029] (b). After the automatic alignment binding machine completes the binding, it detects that when it is detected that the substrate electrode 1 on the substrate 3 and the flexible circuit board electrode on the flexible circuit board, that is, the FPC electrode 2, are aligned accurately, it will also That is t...

Abstract

The invention provides a method for improving binding alignment accuracy of a shadow mask plasma display panel, which realizes effective control over FPC expansion extent through measurement adjustment on binding temperature and binding time within a range required by raw material, so that FPC electrodes (2) with different heating expansion efficiencies can be accurately matched with a substrate electrode (1) respectively. The method improves yield and working efficiency of the shadow mask plasma display panel SMPDP, so that the sealing yield of the shadow mask plasma display panel can reach over 99 percent, and large-scale production of the shadow mask plasma display panel becomes possible. The method improves the adaptability of equipment to materials, lowers requirement to materials, and has the advantages of improving stability and adjustability binding process, and improving yield and working efficiency of the shadow mask plasma display panel.

Description

technical field [0001] The invention relates to an alignment method in the bonding process of a shadow-mask plasma display screen, in particular to a method of pressing and bonding substrate electrodes and flexible circuit board electrodes, that is, FPC electrodes, during the manufacturing process of a shadow-mask plasma display screen. The manufacturing method is specifically a method for improving the bonding alignment accuracy of the shadow mask plasma display screen during the bonding process of the shadow mask plasma display screen. Background technique [0002] The plasma flat-panel display that emerged in the early 1990s has attracted widespread attention for its advantages of digitization, large screen, high resolution, high definition, wide viewing angle, thin thickness and light weight. [0003] At present, the existing plasma flat-panel display PDP adopts three-electrode AC plasma flat-panel display AC-PDP, and the three electrodes are distributed on the front and...
