Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] The preparation method of the front substrate of the plasma display screen of the present invention is carried out according to the following steps:

[0032] Firstly, the transparent electrodes are omitted, and bus electrodes with holes or T-shaped bus electrodes are used, and the electrode patterns of the bus electrodes with holes or T-shaped bus electrodes are photo-etched on the front glass substrate 30;

[0033] When a perforated bus electrode is used

[0034] Firstly, the annealed front glass substrate 30 is cleaned, printed with photosensitive paste, dried, exposed with the motherboard A carrying the decomposed bus electrode pattern, and then developed and fired. The electrode pattern of the motherboard A is composed of The rectangular perforated bus x-electrode 321A pattern and the zigzag perforated bus y-electrode 331A pattern...

Abstract

A method for preparing front base plate of plasma display screen includes photoetching electrode pattern of collecting electrode with hole or T form collecting electrode on front glass base plate, applying a photoetching method to prepare black bar on front glass base plate set with electrode pattern, coating dielectric layer and evaporating protective layer on collecting electrode pattern prepared with black bar.

Description

technical field [0001] The invention belongs to the technical field of flat panel display of plasma display screens, and in particular relates to a method for manufacturing a front substrate in a plasma display screen. Background technique [0002] In recent years, a surface discharge AC type plasma display panel (referred to as a PDP), which is a large and thin color image display device, has gradually become a popular consumer product for home use. [0003] Due to the need to ensure the pixel aperture ratio and the lowest discharge ignition voltage, the three-electrode surface discharge color AC plasma display depends on the transparent electrode ITO film layer during discharge, but the transmittance of the sputtered transparent electrode ITO film Good and conductive thin film layers are more expensive. [0004] In order not to affect the pixel aperture ratio and ensure the lowest discharge ignition voltage, it is necessary to make the bus bus electrode meet a certain wid...
