Problems solved by technology
The above three fabrication methods of bus electrodes have disadvantages: Both the screen printing method and the photosensitive silver paste method need to go through a high-temperature sintering process at about 450°C to remove the organic solvent and adhesive in the conductive silver paste, and to make the paste in the paste The low melting point glass is fused with silver powder, so that the silver can be firmly attached to the substrate
High temperature sintering process has long production cycle and high cost
Compared with the screen printing method, the photosensitive silver paste method has higher precision, but the material utilization rate is low and the waste is large
The thin film photolithography process is more complicated, the production cycle is long, and the investment cost is high

[0024] The substrate is cleaned, and the substrate includes a base glass substrate 1 and a transparent conductive film 2 covered on its surface.
[0025] The photosensitive adhesive 3 is hot-pressed on the surface of the transparent conductive film 2, and the adhesive film should be smooth without air bubbles.
[0026] Exposure: spread the mask plate 4 with line graphics on the surface of the photosensitive adhesive 3 and press it tightly so that the photosensitive adhesive 3 and the mask plate 4 have no gap. Then use ultraviolet light 5 to irradiate mask plate 4 and photosensitive adhesive 3 vertically, ultraviolet light 5 can penetrate the transparent area on mask plate 4 and irradiate the corresponding parts of photosensitive adhesive 3, so that this part of photosensitive adhesive is cured to form a cured The photosensitive glue 6 ; the opaque area on the mask plate 4 can block the irradiation of the ultraviolet light 5 and keep the corresponding parts of the photosensitiv...

The production method of the Plasma Display Panel junction electrode is the production method of the alternating and direct current Plasma Display Panel accordant junction electrode during producing the alternating and direct current Plasma Display Panel. Its production method includes the following steps: a. spread the sensitization glue on the transparent conductive film covered on the surface of the basal lamina; b. exposure: spread the masking board with line drawing on the surface of the sensitization glue and irradiate the masking board and sensitization glue with ultraviolet light; c. developing: spray the processed basal lamina with the photographic developer and get rid of the petrified sensitization glue; d. etching: spray the developed basal lamina with etching solution; e. plating: plate the junction electrode on both sides of the transparent current-carrying electrode; f. stripping of photoresist: put the plated things into the stripping of photoresist solution, marinate it for several minutes, get rid of the petrified sensitization glue on the surface of the transparent current-carrying electrode and finish preparing the junction electrode.
Description
technical field [0001] The invention relates to a method for manufacturing bus electrodes of the AC and DC plasma display panels during the manufacturing process of the AC and DC plasma display panels, and belongs to the technical field of plasma display panels. Background technique [0002] In order to reduce the resistance of the transparent conductive electrode on the front substrate of the plasma display panel, a layer of bus electrode is usually made on the transparent conductive electrode, and a metal material with good conductivity is generally used. The conventional methods include screen printing method, photosensitive silver paste method and thin film photolithography. The screen printing method makes the required electrode pattern on a certain mesh screen by means of exposure and development, uses the conductive silver paste as the raw material of the bus electrode, and then prints the conductive silver paste on the screen printing machine through screen printing....
