    Abstract: An organic light-emitting diode display is disclosed. In one aspect, the display includes a scan line formed over a substrate, a data line formed over the substrate, and a driving voltage line configured to receive a driving voltage. The data line and driving voltage line cross the scan line and are electrically insulated from the scan line. A switching transistor is electrically connected to the scan line and the data line and includes a switching drain electrode. A driving transistor includes a driving source electrode electrically connected to the switching drain electrode and a driving gate electrode including a first storage electrode. A storage line includes a second storage electrode overlapping the first storage electrode. An OLED is electrically connected to the driving transistor, the second storage electrode including an extension at least partially overlapping the data line.

    Abstract: A display includes a plurality of pixels in a non-quadrangular display area and a plurality of first driving circuits and a plurality of second driving circuits in a peripheral area of the display area. Each of the pixels is connected to a first signal line in a first direction and a second signal line in a second direction crossing the first direction. Each of the first driving circuits outputs a first signal to the first signal line of a corresponding one of the pixels. Each of the second driving circuits outputs a second signal to the second signal line of a corresponding one of the pixels. The number of second driving circuits between neighboring first driving circuits is different depending on a position in the peripheral area.

    Abstract: The present disclosure relates to a display apparatus enhancing a display quality and a method of driving the display apparatus. The display apparatus comprises a display panel and a power voltage generator. The display panel comprises a plurality of pixels. The power voltage generator is configured to output a first initialization voltage, a second initialization voltage, a first power voltage, and a second power voltage less than the first power voltage to the plurality of pixels. The power voltage generator is configured to output the second initialization voltage substantially equal to the second power voltage in response to an emergency shutdown signal.
