Abstract: A display driver includes a still image detector configured to receive a compressed image bitstream at an input frame frequency from a host processor, and to detect a still image by comparing the compressed image bitstream of a current frame and the compressed image bitstream of a previous frame, a driving frequency changer configured to output the compressed image bitstream at a first output frame frequency equal to the input frame frequency when the still image is not detected, and to output the compressed image bitstream at a second output frame frequency lower than the input frame frequency when the still image is detected, and a decoder configured to generate original image data at the first output frame frequency and the second output frame frequency.

Abstract: A display device including: a controller including: a zone splitting block configured to divide input image data into a plurality of partial image data respectively corresponding to a plurality of partial panel zones of the display panel; a plurality of panel zone frequency deciding blocks configured to determine a plurality of driving frequencies for the plurality of partial panel zones by analyzing the plurality of partial image data, respectively; a non-driving period setting block configured to classify a plurality of frame periods into a driving frame period and a non-driving frame period based on a maximum driving frequency of the plurality of driving frequencies; and a scan driver control block configured to provide the scan driver input signal to the scan driver in the driving frame period, and to not provide the scan driver input signal to the scan driver in the non-driving frame period.

Abstract: A display device including a display panel which includes pixels connected to gate lines and data lines; and an image display control unit controlling an input image signal to be converted into a data signal and, thereby, display an image on the display panel. The image display control unit outputs the data signal so that a position of an image being displayed on the display panel is changed when the image signal is the same for a preselected time period and sets a next position change time period of the image according to a distance between an original position of the image and a changed position of the image.
