Abstract: A display device includes a display panel including a plurality of pixels respectively connected to a plurality of data lines and a plurality of scan lines, a data driving circuit for driving the plurality of data lines, a scan driving circuit for driving the plurality of scan lines, and a driving controller for receiving a control signal and an image signal and controlling the data driving circuit and the scan driving circuit such that an image is displayed on the display panel. The driving controller identifies a first region and a second region of an image to be displayed on the display panel based on the image signal and provides the data driving circuit with an image data signal obtained by compensating for the image signal to be provided to pixels adjacent to the second region among pixels corresponding to the first region as a compensation value.

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.
