To increase the brightness and/or the life-time of a display, an anode voltage signal may be controllably adjusted during operation of the display. The method may involve, receiving at least one of image signals and external control signals, determining an anode current value for anode current flowing through the anode electrode based on the received at least one of the image signals and the external control signals, comparing the determined anode current value with a reference current value and outputting a comparison result, and adjusting an anode voltage signal to be supplied to the anode electrode based on the comparison result.
