Abstract: A scan driver includes scan signal outputting circuits, at least one of the scan signal outputting circuits includes a driving circuit and a buffer circuit. The driving circuit includes driving transistors. The driving circuit provides first and second driving signals to first and second driving nodes, respectively by turning on or off the driving transistors in response to clock signals and a scan input signal. The buffer circuit includes buffer transistors. The buffer circuit outputs a scan signal at an output node by turning on or off the buffer transistors in response to the first and second driving signals. The at least one of the scan signal outputting circuits performs a back-biasing voltage applying operation on at least one of the driving transistors and the buffer transistors when the driving transistors and the buffer transistors are turned on or off.

Abstract: A pixel includes a driving circuit, a first organic light emitting diode, a second organic light emitting diode, and a self-repair circuit. The driving circuit supplies current based on a data signal supplied through a data line. The first organic light emitting diode is coupled to the driving circuit through a first current path. The second OLED is coupled to the driving circuit through a second current path. The self-repair circuit interrupts the first current path and supplies the current to the second current path when the first organic light emitting diode has a defect.

Abstract: A pixel for an organic light emitting diode (OLED) display is disclosed. One inventive aspect includes an organic light emitting diode, a first transistor, a first capacitor, a second transistor and a second capacitor. The first transistor is configured to control an amount of current flowing from a first power source to a second power source via the organic light emitting diode in response to a voltage of a first node. The first capacitor is connected to a data line and has a first terminal. The second transistor is connected to a second terminal of the first capacitor and a second node and is configured to be turned on when a scan signal is supplied to a scan line. The second capacitor is connected to the second and first nodes.
