1. A display system, comprising:

  • a plurality of Light Emitting Diodes (LEDs) forming a display panel, at least some of the LEDs of the display panel operable in an emit mode, and at least some of the LEDs of the display panel operable in a sense mode;

    a driving circuit adapted to couple to one of the plurality of LEDs operable in the emit mode and structured to cause the one of the plurality of LEDs operable in the emit mode to emit light; and

    a sensing circuit adapted to couple to one of the plurality of LEDs operable in the sense mode and structured to cause the one of the plurality of LEDs operable in the sense mode to sense light energy.
