Abstract
The invention relates to a pixel for an active matrix display comprising an organic light emitting diode (OLED) ( 19 - 23 ) and a driver circuit having a driver transistor that drives the light emitting diode ( 19 - 23 ) and having a capacitor, a current-carrying path of the driver transistor being connected in series with the light emitting diode ( 19 - 23 ) and at least indirectly between two poles of an operating voltage source. A transport layer ( 20 ) of the light emitting diode ( 19 - 23 ) is doped resulting in increased electrical conductivity of the transport layer ( 20 ) and is electrically connected to the drain contact ( 15 ) of the driver transistor.
