1. An integrated display and input device comprising:

  • a display panel for displaying information to a user;

    a pixel array having a plurality of detectors for receiving electromagnetic radiation, each detector of the plurality of detectors operative to detect a change in the electromagnetic radiation caused by an object in propinquity to the display panel and provide an output corresponding to the change; and

    circuitry for receiving the output from each detector of the plurality of detectors, the circuitry operative to;

    determine at least one impingement point for the object relative to the pixel array corresponds to a location of at least one detector of the plurality of detectors when the output from the at least one detector indicates the change in the electromagnetic radiation exceeds a threshold;

    determine a position for the object with respect to the display panel based on the output from the at least one detector and the location of the at least one detector; and

    provide a non-imagewise input, including the position of the object, to utilization circuitry of the integrated display and input device.
