Active matrix display and method for driving an active matrix display

A method for driving an active matrix display comprising a plurality of pixels, wherein each pixel comprises a drive transistor having a driver gate, is disclosed. The method comprises: receiving information of a desired image to be displayed; determining a compensated voltage for the driver gate for each pixel based on calibration data, wherein the calibration data comprises a set of individual calibration values applying to different pixels, and wherein the compensated voltage compensates for differences between pixels affecting a relation of an intensity of light output by the pixel as function of a difference between the voltage applied to the driver gate and a threshold voltage of the drive transistor; and outputting the compensated voltage for the driver gate for each of the pixels.
