Abstract: A display device includes: a pixel part including a plurality of pixels; a first scan driver to provide a first scan signal to each of the pixels; and an initialization controller to control the first scan driver. Each of the pixels includes a pixel circuit including a plurality of transistors, and a light emitting element connected to the pixel circuit, an anode of the light emitting element is to be initialized to a first initialization voltage in response to the first scan signal having a gate-on level, and the initialization controller is to determine whether to provide the first scan signal having the gate-on level to each of the pixels for each frame.

Abstract: A display panel includes a display panel displaying an image including a moving image and a static image; a controller generating first image data to the first area in a first arrangement type, and generating second image data to the second area in a second arrangement type; a scan driver sequentially supplying scan signals to all of pixel rows of the first area during a first period of a first frame and sequentially supplying scan signals to a part of pixel rows of the second area exclusively during a second period of the first frame; and a data driver supplying data signals corresponding to the first image data to data lines during the first period, and supplying data signals corresponding to the second image data to the data lines during the second period.
