Displays with optical edge sensors

A display, comprising:

• a substrate layer;
• active area pixels on the substrate layer configured to display an image in an active area that is free of light sensing circuitry;
• a capacitive touch sensor overlapping the active area configured to gather touch input over the active area;
• an optical sensor that has infrared light-emitting pixels on the substrate layer and infrared light-sensing pixels on the substrate layer, wherein the optical sensor is in a border region that runs along a peripheral edge of the active area and is configured to gather touch input over the border region;
• and
• display control circuitry formed along an edge of the substrate layer and coupled to the active area pixels, the infrared light-emitting pixels, and the infrared light-sensing pixels via corresponding parallel signal lines.

A display, comprising:

• a substrate;
• and
• an array of pixels formed in rows and columns on the substrate, each pixel in the array comprising thin-film circuitry on the substrate, wherein the array of pixels comprises:
• active area pixels on the substrate that are configured to display an image in an active area that is free of light sensing circuitry;
• and
• light-sensing pixels on the substrate that extend along a border region running along a peripheral edge of the active area and that sense light indicative of user input outside of the active area, wherein the light-sensing pixels at least partly form an optical sensor in the border region and wherein the border region does not have pixels that display images.
