ABSTRACT:
The present invention discloses resistive touch sensors that incorporate microstructured conductive layers. When local electrical contact is made between the microstructured conductive layer and an opposing conductive layer due to a touch input, the resulting signal can be used to determine the location of the touch. The microstructures can be used to penetrate a solid, deformable filler material disposed between the conductive layers, for example to provide more transmission of light through the sensor. The microstructures can also provide additional functionalities such as z-axis sensitivity, image direction, light control, light extraction, and so forth.
