摘要： A scan driver of an organic light emitting diode (OLED) display device includes a plurality of sequentially-connected stages each connected to a plurality of pixels through a plurality of first-scan lines and a plurality of second-scan lines. Each stage of the sequentially-connected stages includes a common driver and a sub-driver unit. The common driver is configured to concurrently provide a common first-scan signal to the first-scan lines of the stage in response to at least a first initialization signal and a second initialization signal. The sub-driver unit is configured to serially provide second-scan signals to the second-scan lines of the stage in response to a plurality of output enable signals, the first-scan signal, and one of the first initialization signal and the second initialization signal. An order of the serial providing of the second-scan signals to the second-scan lines is dynamically configurable based on the output enable signals.

摘要： A display apparatus includes a timing controller, a data driver and a display panel. The timing controller receives input image data at a first frequency substantially equal to a frame rate of an input image. The timing controller generates a data signal having the first frequency based on the input image data having the first frequency. The data driver converts the data signal into a data voltage. The display panel displays an image based on the data voltage.
