1. An integrated display and input device, comprising:
- a pixel array configured to provide a visually sensible output;
at least one sensor configured to sense at least a position of at least one object with respect to the pixel array when the at least one object has at least a predetermined degree of propinquity to the pixel array;
circuitry configured to receive an output from the at least one sensor and to provide a non-imagewise input that is representative of the position of the at least one object relative to the pixel array;
at least one IR illuminator for illuminating the at least one object when it has the at least a predetermined degree of propinquity to the pixel array; and
wherein the at least one illuminator is further configured to function as at least one backlighting illuminator associated with the pixel array.

31. A position sensing assembly comprising:
-
a plate defining a surface; at least one pixel array including a plurality of detector elements configured to detect electromagnetic radiation at a baseline level, the at least one pixel array being configured to sense a position of an object with respect to the surface according to locations of ones of the plurality of detector elements at which at least one of the amount of radiation detected and the change in the amount of radiation detected exceed a predetermined threshold, the at least one pixel array being configured to sense at least a position of at least one object with respect to the at least one pixel array when the at least one object has at least a predetermined degree of propinquity to the at least one pixel array; circuitry configured to receive an output from the at least one pixel array and to provide a non-imagewise input that is representative of the position of the at least one object relative to the at least one pixel array; and wherein the change in the amount of radiation detected results from ones of the plurality of detector elements detecting reflected light from the object in addition to detecting the radiation at the baseline level. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43)
