Abstract:
A pixel includes an organic light emitting diode and a pixel control circuit. The pixel control circuit includes a first transistor, a second transistor, and a third transistor. The first transistor controls an amount of current to the organic light emitting diode from a first power source based on a voltage applied to a first node. The second transistor is coupled between the first node and a data line and turns on when a scan signal is supplied to a scan line. The third transistor is coupled between the first power source and a second node that is a common terminal of first and second capacitors, which are coupled in series between the first node and the first power source. In operation, the third transistor turns on when a first control signal is supplied to a first control line.
