More Information
Summary:Input device backlighting techniques are described. In one or more implementations, an input device includes a light guide configured to transmit light, a sensor assembly having a plurality of sensors that are configured to detect proximity of an object as a corresponding one or more inputs, a connection portion configured to form a communicative coupling to a computing device to communicate the one or more inputs received by the sensor assembly to the computing device, and an outer layer. The outer layer has a plurality of indications of inputs formed using openings in the outer layer such that light from the light guide is configured to pass through the openings to function as a backlight. The outer layer also has a plurality of sub-layers arranged to have increasing levels of resistance to transmission of the light from the light guide, one to another.
