Arrangement For a Touch Sensitive Apparatus

摘要

An arrangement for a touch sensitive apparatus comprises a light transmissive panel having a front surface and an opposite rear surface defining an optical media for transmitting light signals via total internal reflection. A shield layer is arranged at the rear surface of the light transmissive panel and is substantially non-transparent to visible light from the front surface. A refractive layer is arranged between the light transmissive panel and the shield layer and allows a light signal to propagate by total internal reflection within the light transmissive panel. At least one aperture is arranged through the shield layer and the refractive layer and is configured to allow a light signal to pass through the aperture.;The shield layer, the refractive layer, and the aperture are arranged at the periphery of the light transmissive panel.
