ABSTRACT:
A front glass sheet having a viewing window and conventionally received within a casing of a solid state wristwatch, is made of electrically conductive glass material which manifests conductivity per se, for serving as one of the principal components of a touch sensitive electrode assembly. In one preferred form, the front glass sheet is made of amorphous (glass) semiconductor such as chalcogenide glass of resistivity less than several hundred K.OMEGA. cm.
