US Patent 10510812 Display-integrated infrared emitter and sensor structures

In one embodiment, an electronic display includes a first plurality of hexagon-shaped pixels and a second plurality of hexagon-shaped pixels that are coplanar with the first plurality of hexagon-shaped pixels. The first plurality of hexagon-shaped pixels each include an infrared (IR) emitter subpixel that is operable to emit IR light. The second plurality of hexagon-shaped pixels each include an IR detector subpixel that is operable to detect IR light. Each IR emitter subpixel and each IR detector subpixel includes an anode layer and a cathode layer. Each particular IR emitter subpixel includes an IR emissive layer located between the anode layer and the cathode layer of the particular IR emitter subpixel. Each particular IR detector subpixel includes an IR detector layer located between the anode layer and the cathode layer of the particular IR detector subpixel.
