Abstract
A multi-functional active matrix display comprises a transparent front sheet, a semi-transparent layer of light emissive devices adjacent the rear side of the front sheet and forming a matrix of display pixels, and a solar cell layer located behind the light emissive devices for converting both ambient light and internal light7 from the light emissive devices into electrical energy, the solar cell layer including an array of electrodes on the front surface of the solar cell layer for use in detecting the location of a change in the amount of light impinging on a portion of the front surface of the solar cell layer.
