Abstract
An active matrix electroluminescent display device comprises an array of display pixels (10) which each include a current-driven electroluminescent display element (20) connected to a driving device (22) controlling the current flowing through the display element in a drive period according to a voltage stored on a capacitance (36) and determined by a data signal applied in a preceding address period. In order to compensate for ageing effects in the display element, electro-optic devices (45, 40) are included in the pixel for adjusting the voltage stored on the capacitance in dependence on the light output of its display element during the address period.
