1. A display device for sensing the proximity of a touch, comprising:

  • an organic light emitting diode (OLED) display comprising OLED materials forming a plurality of nodes configured to emit light when drive circuitry provides a signal across the plurality of nodes at or above an illumination threshold; and

    measurement circuitry disposed proximate to the plurality of nodes, wherein the measurement circuitry is configured to sense the light reflected off of an object positioned over the OLED display and passed through the OLED materials, and wherein the measurement circuitry is further configured to provide a measurement signal responsive to the sensed reflected light.
