According to another aspect of the invention, the present invention provides a kind of electrode and the PDP that comprises this electrode that uses method for preparing.
Disclosure of an invention
Below, will be elaborated to the present invention.
According to the present invention, above-mentioned electrod composition is coated on the prebasal plate and metacoxal plate of PDP through lithographic printing, thereby can repeat to form fine pattern, and said pattern is subsequently through forming electrode such as heat treatments such as calcinings.Thereby, with reference to accompanying drawing, imprint lithography is described at first.
Imprint lithography of the present invention (offset process) was divided into for two steps, i.e. shifting process (offprocess) and typography (set process).Before shifting process, composition 14 of the present invention is loaded in the gravure roll 11 that is formed with the dark fine pattern with 50～150mm live width of 10～50mm, strike off technology for wiping the composition that overflows from gravure roll off with metallic spatula 12 then.Subsequently, carry out shifting process: blanket roll 15 is continued nip drum on the gravure roll that composition is housed 11, make above-mentioned composition be transferred on the surface of the blanket roll 15 that forms by silicon rubber from the groove of gravure roll 11.
Then, carry out typography: blanket roll 15 nip drum on glass substrate 17 that will process by silicon rubber, with composition from the surface transfer of silicon rubber blanket to glass baseplate surface.
The present invention aims to provide and is applicable to lithographic electrod composition; Thereby in imprint lithography; Composition in the groove of gravure roll is transferred on the silicon rubber blanket equably and not produce pattern outstanding or lines are damaged; The composition that is transferred to subsequently on the silicon rubber blanket preferably is transferred on the glass substrate with the form of fine electrode pattern, and does not remain on the blanket.
At last, the present invention is used for lithographic electrod composition and comprises: a) electric conducting material of 50～95wt%, the b) organic binder bond of 1～20wt%, and c) glass dust of 1～20wt%, all the other are solvent.
