- A display device according to an embodiment of the present invention can comprise a display panel, a power delivery network, an image controller and a PDN controller. The display panel can comprise aplurality of sub-panels. The power delivery network can be controlled by a control signal, deliver a voltage determined by the control signal to each of the plurality of sub-panels, and generate stateinformation for determining the control signal. The image controller can receive and store frame image data, determine the number of frames to be integrated on the basis of a window size, and generate integrated image data by integrating frame image data of the determined number of frames into a single image. The PDN controller can generate a control signal and a size adjustment signal on the basis of the state information and the integrated image data, provide the generated image signal to the power delivery network, and provide the generated window adjustment signal to the image controller.The size adjustment signal can adjust the window size.
