Abstract
Flexible translucent electroconductive plastic film electrodes are produced by perforating a normally nonconductive translucent plastic film, and then applying to both surfaces of the film thin layers of a conductive metal oxide such as indium-tin oxide. The conductive layers communicate through the perforations to form an electroconductive film electrode useful with an electroluminescent layer and a rear electrode to form lights, signs and similar electroluminescent laminates.
Claims20
A strong, flexible, translucent electroconductive plastic film electrode comprising a thin, normally non-electroconductive sheet of strong, flexible, translucent plastic film which is provided with a plurality of closely-spaced narrow openings through the thickness thereof and over the entire surface area thereof, said sheet being coated over the front and rear surfaces thereof with a continuous translucent layer Of an electroconductive composition which extends through said openings to produce electroconductive continuity between said front and rear surfaces and form said plastic film electrode.
A method for producing a strong, flexible, translucent electroconductive plastic film electrode comprising the steps of:
- (a) forming a plurality of closely-spaced, narrow openings through the thickness of and over the surface area of a normally non-conductive sheet of strong, translucent plastic film, and
- (b) coating the front and rear surfaces of said plastic film with a thin, translucent, continuous layer of an electroconductive composition which extends through said openings to produce electroconductive continuity between said front and rear surfaces and form said plastic film electrode.
