    Abstract: A display device includes display panels, a data converter that renders input image data to convert the input image data corresponding to edge regions of the display panels adjacent to a boundary portion between the display panels into correction data, and a driving controller that receives the correction data and generates a control signal that drives the display panels based on the correction data. The data converter generates the correction data in which an image displayed in the edge region is shifted based on a difference between values of the input image data corresponding to the edge regions of the display panels adjacent to the boundary portion between the display panels adjacent to each other.

    Abstract: A display device includes a display panel including a first partial panel region and a second partial panel region, and a panel driver configured to drive the display panel. The panel driver determines a first driving frequency for the first partial panel region and a second driving frequency for the second partial panel region. When the first driving frequency and the second driving frequency are different from each other, the panel driver sets a boundary portion including a boundary between the first partial panel region and the second partial panel region, and determines a third driving frequency for the boundary portion to be between the first driving frequency and the second driving frequency.
