preparation example Construction

[0025] In a typical implementation of the present invention, a method for preparing a display electrode in a plasma display screen includes the following steps: printing a paste containing a first metal material on a glass substrate to form a first electrode part; The glass substrate with the first electrode part is immersed in the second metal solution, and the second electrode part is formed on the surface of the first electrode part; the chemical activity of the second metal is smaller than that of the first metal.

[0026] The display electrode in the plasma display screen provided by the present invention and the preparation method thereof, by using the low-cost first metal paste instead of the silver paste for printing, drying, exposure, development, sintering and other processes, greatly save the use of silver, effectively cut costs. And wrap the second metal similar to Ag on the outside of the first metal paste layer to form the second electrode layer through the repla...

Abstract

The invention discloses a display electrode of a plasma display panel and a production method of the display electrode. The production method of the display electrode of the plasma display panel includes steps: printing paste containing a first metal material onto a glass substrate to form a first electrode portion; and impregnating the glass substrate with the first electrode portion into second metal solution to form a second electrode portion on the surface of the first electrode portion, wherein the chemical activity of the second metal is lower than that of the first metal. Silver paste is substituted by the low-cost first metal paste for printing, drying, exposing, developing, sintering and the like, so that silver is greatly saved, and cost can be reduced effectively. The second metal similar to the silver is wrapped outside the metal paste layer to form the second electrode layer under the replacement reaction, and accordingly electrical conductivity is improved, the display electrode can be thinned, the thickness of front plate dielectric is reduced indirectly, and luminous efficiency is improved.

Description

technical field [0001] The invention relates to the field of plasma display screens, in particular to a display electrode in a plasma display screen and a preparation method thereof. Background technique [0002] In the PDP manufacturing process, the mainstream manufacturing process of display electrodes is to use electrode paste composed of silver particles and glass powder, form a layer of film through printing and coating processes, and then undergo drying, exposure, development, film stripping, sintering and other processes. to form display electrodes. However, the display electrodes formed by this traditional process have two disadvantages. [0003] First, the waste of silver is serious. Some silver will be wasted during printing, and a large amount of silver will be wasted during development. Even if it is recycled, there is still a lot of waste, and silver recycling and reprocessing also require a lot of cost. [0004] The second is that in the traditional process, ...
