Abstract: A display device includes a driving controller controlling a data driving circuit and providing a clock signal and a driving voltage in response to an image signal and a control signal received from an external source. The driving controller restores a data enable signal having a display period and a blank period in one frame on the basis of the control signal and sets a voltage level of the driving voltage applied to the gate driving circuit in accordance with a duration of the blank period. During a sequence of frames having a changing frame rate, the driving voltage for each respective frame may be set based on the duration of each respective blank period.

Abstract: A display device includes a display panel, and a timing controller which includes a memory unit and an image data conversion unit where when a mode selection signal includes information about a first mode at an (n+1)th frame (n is a positive integer), the memory unit maintains a first frame image data stored before the (n+1)th frame among an image data, when the mode selection signal includes information about a second mode, the memory unit stores second frame image data inputted during the (n+1)th frame among the image data, and the image data conversion unit rearranges pixel data included in the data stored in the memory unit among the first frame image data and the second frame image data, and outputs converted image data.
