Method of making a transparent touch screen switch assembly

摘要: A touch-sensitive matrix switch assembly includes a pair of transparent insulating substrates having conductive row strips and column strips. The are separated by longitudinal extending channels, an spacer strip is deposited in each channel channel. mounted together with the conductors transversely respect to conductors. An air gap between provided engagement against space formed very small diameter glass or polymer particles which mixed adhesive volatile solvent. particle/adhesive mixture sprayed into channels through mask produce transparent, non-conductive deposit enlarged slightly out channel, thereby defining strip. In analog touch assembly, dots applied onto surface resistive sheet pneumatically sputtering coated adhesive.
