Abstract
A display panel for concurrent video output and eye position tracking. The display panel includes a substrate, a plurality of visible light emitting diodes (LEDs) positioned on a side of the substrate, and a plurality of light detectors positioned on the side of the substrate. The visible LEDs transmit quasi-collimated visible light propagating away from the side of the substrate. The light detectors capture invisible light propagating toward the side of the substrate, reflected from an eye of the user. In some embodiments, non-visible LEDs are formed on the side of the substrate. The visible LEDs, light detectors, and non-visible LEDs may be arranged to form pixels of the display panel. The quasi-collimated light emitted from the visible LEDs reduces spread into beam paths of the invisible light between the non-visible LEDs and the light detectors.
