A system for compensating for non-uniformities in an array of solid state devices in a display panel displays images in the panel, and extracts the outputs of a pattern based on structural non-uniformities of the panel, across the panel, for each area of the structural non-uniformities. Then the structural non-uniformities are quantified, based on the values of the extracted outputs, and input signals to the display panel are modified to compensate for the structural non-uniformities. Random non-uniformities are compensated by extracting low-frequency non-uniformities across the panel by applying patterns, and taking images of the pattern. The area and resolution of the image are adjusted to match the panel by creating values for pixels in the display, and then low-frequency non-uniformities across the panel are compensated, based on the created values.

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 lightfrom 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.
