Organic light emitting display device including a plurality of scan driving circuits for driving scan signals corresponding to image signals and black image signals and method of driving the same
A light emitting display is configured to reduce or prevent motion blur by shortening a time that a black frame is displayed between image frames. One embodiment includes display region, a data driver, a scan driver, and a controller. The display region displays frames of images according to a data signal and a scan signal. The data driver transmits data for displaying first frames and second (black) frames between the first frames. The scan driver includes first and second scan driving circuits for transmitting scan signals, and a switch unit for selectively coupling the first and second scan driving circuits. The scan driver transmits scan signals sequentially during the first frames and transmits scan signals to at least two of the scan lines concurrently by driving the first and second scan driving circuits in parallel during the second frames. The controller transmits a driving control signal to control the switch.
