Abstract
A method of controlling an array of pixels in an active matrix display to a predetermined emission level is provided. The pixels are arranged in a plurality of rows and a plurality of columns, each pixel having an active matrix element. The method makes use of a plurality of sensors each having a measurable sensor parameter and at least one pixel driver. Light emission is varied from a plurality of pixels in a first row using the pixel driver and the active matrix elements in the pixels. Light emission is received from the pixels at the sensors and a measured value of the measurable sensor parameter is obtained responsive to the received light emission. For each of the plurality of pixels, a control signal is generated for the pixel to maintain constant emission from the light source at the predetermined emission level.
