    摘要: A pixel cell in an active matrix display comprising a current driven emissive element such as an OLED (20) and a data input (17) for receiving an analogue data signal (Vin). The pixel has at least two drive elements (12, 14), each being connected to a power supply (16) and arranged to drive the emissive element in accordance with the data signal, and selecting means (22, 24) for providing, in response to a select signal (21, 23), the data signal to at least one of the drive elements (12, 14). Further, each drive element is adapted to drive the emissive element (20) in a different drive current range in response to a given data signal. Thereby, a required brightness range can be obtained while data voltages too close to the threshold voltage may be avoided.

    摘要: The invention relates to an electroluminescent display comprising a first display pixel and a second display pixel formed on a substrate. The display pixels comprise a first electrode deposited on or across the substrate, an electroluminescent layer and a second reflective electrode. The first and second display pixels are separated by a region comprising at least one insulating structure. The insulating structure is adapted to suppress the output of light at the second display pixel reflected at the second reflective electrode, which light is incident from at least the first display pixel and/or the substrate. The insulating structure reduces crosstalk of light between the first and second or further display pixel and can be easily integrated in the manufacturing process of the electroluminescent display.
