    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.

    Abstract: A method of repairing a display substrate includes electrically separating a defective pixel circuit from a pixel electrode and irradiating a laser beam on first and second intersection regions. The laser beam is irradiated on the first intersection region to weld a pixel connection part to a first repair line. The pixel connection part is connected to the pixel electrode at the first intersection region, and intersects the first repair line. The first repair line includes a first welding hole at the first intersection region. The laser beam is irradiated on the second intersection region to weld a dummy connection part of a dummy circuit to a second repair line. The second repair line intersects the dummy connection part at the second intersection region, and is separated from the pixel circuit. The second repair line includes a second welding hole at the second intersection region.
