A display device includes: a display panel comprising a display area configured to display an image, wherein the display area includes a measurement area including a plurality of sub-measurement areas, and each of the plurality of sub-measurement areas includes a plurality of pre-map areas; a data driver configured to provide data voltages to the display panel; a signal controller; and a common voltage generator configured to provide a common voltage to the display panel, wherein an afterimage reduction mode is driven to change a level of the common voltage provided by the common voltage generator when the determined pre-map areas are adjacent to each other.

Display device

A display apparatus includes a timing controller, a common voltage generator, a data driver, and a display panel. The timing controller determines a representative grayscale of each frame based on input image data and generates a common voltage control signal having a first digital value ratio ('DVR') value corresponding to a first frame, a representative grayscale of the first frame being included in a first grayscale range. The common voltage generator generates a first common voltage based on the common voltage control signal. The data driver generates a data voltage based on the input image data. The display panel displays an image corresponding to the first frame based on the data voltage and the first common voltage.
