1. A method of controlling light emission from a pixel circuit including a light emitting device (LED), a drive transistor to provide a programmable drive current to the light emitting device, a programming input, and a storage device to store a programming value from said programming input, the method comprising:
determining at least one time-dependent parameter of the pixel circuit, detecting a change in said determined time-dependent parameter, determining calibration data for the pixel circuit based on the detected change in the determined time-dependent parameter; storing said calibration data in a calibration memory; and adjusting the programming value to the pixel circuit based on the stored calibration data to at least partially compensate for said detected change in the time-dependent parameter.
