Abstract: A method of driving a display device, which includes a plurality of segments, each including a plurality of pixels, includes comparing grayscales of first image data of a first frame with respect to a segment among the plurality of segments and grayscales of a second image data of a second frame after the first frame with respect to the segment, modulating the second image data to generate first modulated data when the grayscales of the first image data are equal to the grayscales of the second image data, and providing data voltages to the segment based on the first modulated data.

Abstract: A display device includes a first display part and a second display part each configured to display images. The second display part is configured to selectively operate in a first mode and a second mode. In the first mode of operation, the second display part displays an image at a first viewing angle. In the second mode of operation, the second display part displays the image at a second viewing angle smaller than the first viewing angle.

Abstract: A display apparatus includes a display panel, a gate driver, a data driver and a driving controller. The display panel includes an edge area having a rounded shape in a first state and having a flat shape in a second state. The gate driver applies a gate signal to a gate line of the display panel, the data driver applies a data voltage to a data line of the display panel, and the driving controller processes input image data according to the first state and the second state. The display panel includes a first display area having a first pixel density and a second display area having a second pixel density less than the first pixel density. The second display area corresponds to the edge area of the display panel.
