  • Publication number: 20240096301
    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.
