Abstract
Apparatus and method for both displaying graphical output and for sensing, e.g., multi-touch input are provided. A light-emitting diode ('LED') matrix-array may be configured to both emit and sense light. The array may be driven in such a way so as to enable the array itself to act as the illumination source preferable for either reflective or scattering optical touch sensing. The need for additional opto-electronic components, or an external illumination source, is thus eliminated or at least reduced. Additionally, the matrix-arrays have large dimensions.
