    摘要： The display comprises an array of pixel circuits each comprising an emitter 1 in series with a current modulation transistor, and at least one address circuit, which integrates, for each column, a differential amplifier and a passive element preferably a resistive element, which cooperate with the current modulation transistors so as to form, during address phases in which the emitters are switched “out of the circuit”, a voltage-programmable current generator. After the address phases, thanks to a suitable switch, the emitters are switched “into the circuit” and supplied with the preprogrammed current. Such a display allows the image display quality to be inexpensively improved.

    摘要： Diode for which one of the conducting layers presents a suitable surface resistance so that when a power supply voltage is applied between a connection element and this conducting layer and the other conducting layer, a potential distribution is generated at the surface of this resisting conducting layer which is able to cause light to be emitted by a portion of the surface of the organic light emitting layer which is proportional to this power supply voltage. This diode is advantageously used to visualise the signal value.
