Abstract: A display includes a display area that emits light and a border region surrounding at least a portion of the light emitting region. A light guide plate is overlaying the display area. A lighting module is operatively interconnected with the light guide plate to provide light to the light guide plate and positioned within the border region, and a one camera module is operatively interconnected with the light guide plate to sense light from the light guide plate and positioned within the border region. The display determines a position of a touch on the light guide plate by determining a location of frustrated total internal reflection within the light guide plate as a result of the touch on the light guide plate.
