Abstract: A display device includes a display panel that displays an image, a panel driver that drives the display panel, and a driving controller that controls driving of the panel driver. The driving controller compensates first image data corresponding to a first area of the display panel where a still image is displayed during at least a predetermined time period, in a first compensation method to generate first compensation image data for the first area, and compensates second image data corresponding to a second area of the display panel different from the first area in a second compensation method different from the first compensation method that uses a load calculated based on previous image data.

Abstract: A display device includes a controller, a panel driver, and a voltage generator. The controller generates a first control signal and generates image data and a second control signal in response to first and second image signals. The panel driver generates a driving signal in response to the image data and the first control signal to drive a display panel. The voltage generator generates a driving voltage to drive the display panel and changes a voltage level of the driving voltage in response to the second control signal. The first image signal corresponds to a second frame located before a third frame in which the driving voltage is changed. The second image signal corresponds to a first frame located before the second frame. The controller generates image data corresponding to the second frame in response to the first image signal and the second image signal.
