Abstract
A disclosed display device includes a display panel with a plurality of pixels and a plurality of signal lines respectively connected to the pixels, and a panel driving circuit to drive the signal lines. The display device further includes a timing controller to receive a first panel self-refresh (PSR) signal and an input image data from a host system, to sense whether the input image data has a preset video format based on the first PSR signal and, if the input image data is sensed to have the preset video format, to control the panel driving circuit to perform normal driving of the signal lines at a first frame frequency in a first group of frames and interlaced low-speed driving of the signal lines at a second frame frequency lower than the first frame frequency in a second group of frames to display the input image data.
