Abstract

Drive electronics is arranged to monitor the light output of each display element throughout the life of a display (336), either directly or by way of an electrical parameter of the display element, and to make adjustments to electrical drive waveforms of the display elements throughout the life of the display (336), in order to compensate for initial non-uniformity and subsequent differential ageing between the display elements.
