Embodiment 1

[0030] A method for manufacturing a metal electrode on a front plate of a shadow mask type plasma display panel, the specific steps are as follows:

[0031] 1. Clean the common soda-lime glass substrate 1.

[0032] 2. Slurry preparation, put the black glass slurry 2 and white photosensitive silver slurry 3 into a clean mixing box and weigh them, put them into the stirring and defoaming machine, adjust the balance according to the weight of the slurry, and set the stirring and defoaming time After the slurry has been stirred and defoamed, it is taken out from the mixer and cooled to room temperature.

[0033] 3. A layer of black glass paste 2 is evenly coated on the front substrate through multiple printings by using screen printing technology, and the printing thickness of the black glass paste 2 is 18-40 μm.

[0034] The specific operation process of each printing is: the black glass paste 2 prepared in the previous process is evenly coated on a certain mesh screen, the prin...

Embodiment 2

[0046] In the above-mentioned embodiment 1, the cured paste with the electrode pattern is sintered under the firing conditions of 550°C and 40 minutes of heat preservation, which constitutes the second group of embodiments of the present invention.

Abstract

The invention discloses a manufacturing method for shadow mask type plasma display panel front substrate metal electrode, which takes general sodium-calcium glass as the shadow mask type plasma display board front substrate and black glass slurry excluding sliver particles as bottom layer isolating material to increase thickness of the black glass slurry coated on the glass substrate, to reduce sintering temperature of the electrode, and to prevent sliver irons from dispersing into the glass substrate and reacting with elements like Na, K and so on in the process of sintering, thus reaching the effect of etiolation of the panel, in the meantime, the shadow mask type plasma display panel front substrate metal electrode whose parameters like size, shape and resistance meet the design requirement is obtained. The invention replaces PD200 glass with higher price and special for the plasma display panel by the general sodium-calcium glass and replaces the black glass slurry comprising silver by the black glass slurry excluding the sliver particles, which are both beneficial for lowering the manufacturing cost of the shadow mask type plasma display panel front substrate metal electrode. The invention uses the black glass slurry as the bottom layer isolating material to promote contrast grade of the shadow mask type plasma display panel and intensify adhesive force between the electrode and the glass substrate.

Description

technical field [0001] The invention relates to a manufacturing technology of a plasma display, in particular to a method for manufacturing a metal electrode of a plasma display, in particular to a method for manufacturing a metal electrode of a front plate of a shadow mask type plasma display panel. Background technique [0002] Thick film photolithography has been widely used in the production of metal electrodes on the front plate of plasma display panel (PDP), and this method is also the main method for making metal electrodes on the front plate of shadow mask type plasma display panel. The process of using the thick film method to make the front plate metal electrode is: coating a layer of black glass paste on the glass substrate, after drying, coating the white photosensitive silver paste on the surface and drying, and then forming by exposure, development and other processes The electrode pattern is finally fired at a high temperature to decompose the resin and other ...
