An active matrix display and a method for driving an active matrix display

A method for driving an active matrix display comprising a plurality of pixels (110), wherein each pixel (110) comprises a drive transistor (120) having a driver gate (122) and a calibration gate (129), is disclosed. The method comprises: receiving information of a desired image to be displayed; determining a compensated voltage for the driver gate (122) for each pixel (110) based on calibration data; and outputting the compensated voltage for the driver gate for each of the pixels. The calibration data comprises a set of individual calibration values applying to different pixels (110), wherein said compensated voltage compensates for differences between pixels affecting a relation of an intensity of light output by the pixel (110) as function of a difference between the voltage applied to the driver gate (122) and a threshold voltage of the drive transistor (120).
