In one embodiment, a touch sensor comprises a beamsplitter operable to reflect a first portion of light incident on the beamsplitter and transmit a second portion of light incident on the beamsplitter, a substrate, and one or more lines of conductive material disposed on the substrate, the lines of conductive material disposed between the first substrate and the beamsplitter.

Reduction of touch sensor pattern visibility using beamsplitters

In one embodiment, an apparatus may include a first mesh of conductive material covering an area corresponding to at least a portion of the touch sensor. The first mesh includes a number of mesh cells. Each of the mesh cells has a number of vertices. Each of the vertices has a substantially randomized location within an inner portion of one of a number of polygons. The polygons collectively and contiguously covers the area corresponding to at least a portion of the touch sensor. One or more dimensions of the polygons is based at least in part on a pre-determined distance threshold between one or more pairs of opposing vertices. The apparatus also includes a computer-readable non-transitory storage medium coupled to the touch sensor and embodying logic that is configured when executed to control the touch sensor.

Generic randomized mesh design

In one embodiment, an apparatus includes a substrate including material having a low birefringence. One or more electrodes of a touch sensor are disposed on the substrate.

Low-birefringence substrate for touch sensor

According to one embodiment, an apparatus comprises a substrate, a touch sensor, and a cover lens. The touch sensor is disposed on the substrate. A conductive mesh forms portions of the touch sensor, and the conductive mesh comprises fine lines of metal. The cover lens is coupled to the touch sensor and is at most 0.4 mm thick. The cover lens comprises plastic.
