Method for making interactive information devices with spacer elements
Abstract:
An interactive information device for use as a touch panel, touch screen, digitizer panel, or pen-input device, and a method for making such a device includes a first, transparent, electrically conductive layer supported by the rigid substrate, a flexible, transparent substrate at least partially aligned with the rigid substrate and having a second, transparent, electrically conductive layer on a surface thereof, the second conductive layer being spaced from the first conductive layer. A plurality of transparent insulating spacer members/dots are positioned on one or both of the conductive layers to allow the conductive layers to engage when the flexible substrate is pressed. The spacer members/dots comprise polymeric material including at least some inorganic material, and more preferably, comprise organic-inorganic nanocomposites having an index of refraction optically matched to the transparent, electrically conductive layer on which they are positioned.
