ABSTRACT:
An active matrix electroluminescent display device has an array of pixels (10), each pixel having a plurality of current-driven display elements (11a–d), for example comprising organic electroluminescent material, connected in a series arrangement with one another and with drive means (12) operable to control the current through the respective series arrangement. By sub-dividing each pixel in this way, the high voltage drops, that can occur along power supply lines, are reduced thus improving the uniformity of the light outputs from the display elements across the display area.
