    Abstract: A display device including a controller and a display panel. The controller receives original image data and output a display image signal. The display panel receives the display image signal and displays a display image corresponding to the display image signal. The controller includes an image shift controller and a memory. The image shift controller generates shifted image data by modulating the original image data to shift the display image sequentially along a preset shift path on the display panel. The memory stores a shift path value indicating a distance by which the display image has been shifted on the preset shift path. The image shift controller generates the display image signal by processing the shifted image data. When the display device is powered on, the image shift controller generates shifted image data corresponding to a shift path value stored in the memory.

    Abstract: A display device includes a display panel including a plurality of display areas; a driving circuit to control the display panel; a timing controller to control the driving circuit to display an image on the display panel; a storage medium to store a plurality of weight tables respectively corresponding to the plurality of display areas; and a load value generator to generate a first load value corresponding to a first data unit of input image data, and to apply a weight to the first load value based on a first weight table corresponding to a display area in which the first data unit is to be displayed, among the plurality of weight tables. The timing controller controls the driving circuit with reference to a weighted first load value.

    Abstract: A display device includes a pixel component including first pixels which emits light having a first color, and second pixels which emits light having a second color different from the first color, a sensing component which extracts, during a sensing period, first sensing data from the first pixels, and second sensing data from the second pixels, and a temperature determiner which senses a temperature of the pixel component using the first sensing data and the second sensing data. The temperature determiner senses, when the first sensing data is supplied to the temperature determiner, the temperature of the pixel component at least one time.
