ABSTRACT:
A pixel circuit for an OLED element comprises first, second, third and fourth transistors wherein controllable conduction paths of the first and second transistors are connected for receiving a data signal current, and the control electrodes thereof are connected for receiving a select signal for being enabled thereby. The third and/or fourth transistors are connected for establishing a current in the OLED element responsive to the data signal current and the select signal. Capacitance may be provided by at least one of the transistors or by additional capacitance.
