    Abstract: A display device includes data lines, scan lines, and pixels. Each of the pixels includes an organic light emitting diode, a first transistor (OLED), and a second transistor. The first transistor is electrically connected to an anode of the OLED. The second transistor is electrically connected to the first transistor, a scan line among the scan lines, and a data line among the data lines. The second transistors of the pixels may receive instances of a reference voltage from the data lines during a first period of a frame. The second transistors of the pixels may simultaneously receive instances of a turn-on scan signal from the scan lines during the first period of the frame. Cathodes of the OLEDs of the pixels may receive instances of a turn-off voltage for the OLEDs to turn off during the first period of the frame.

    Abstract: A display device is disclosed that includes a pixel component configured to output an image based on a first driving frequency, a scan driver configured to sequentially provide a scan signal to each pixel row in each frame based on the first driving frequency, and a driving controller configured control the scan driver such that, in the case where image data includes data corresponding to a static image, a display area is divided into a first area for the static image, and a second area for a video, and the first area is driven at a second driving frequency, and the second area is driven at a third driving frequency. The driving controller may control the scan driver such that a driving frequency corresponding to the first area is reduced to the second driving frequency, and a driving frequency corresponding to the second area is increased to the third driving frequency.
