Angularly-selective sensor-in-pixel image detection
Abstract:
A display system configured for multi-touch input is provided. The display system comprises a display surface, a local light source to illuminate the display surface with infrared light, and an image-producing display panel. The image-producing display panel comprises a plurality of image sensor pixels positioned within a sensor layer of the image-producing display panel. The image-producing display panel further comprises an angularly-selective layer positioned between the display surface and the sensor layer, wherein the angularly-selective layer is configured to transmit light having a first range of incidence angles with the surface normal of the angularly-selective layer to a first sensor pixel of sensor layer, and to reflect light having a second range of incidence angles from a second sensor pixel of the sensor layer, where the second range is greater than the first range of incidence angles with respect to a surface normal of the sensor layer.
