    Abstract: A display device which includes a display panel that includes a first display area and a second display area, and a driving controller. During a multi-frequency mode, the driving controller drives the first display area by using a first driving frequency and drives the second display area by using a second driving frequency. During the multi-frequency mode, when the second driving frequency changes from a first frequency to a second frequency, the driving controller drives the first display area and the second display area during at least one frame by using a base frequency, drives the first display area and the second display area during at least one second frame by using an intermediate frequency between the base frequency and the second frequency, and then drives the first display area by using the first driving frequency and drives the second display area by using the second frequency.

    Abstract: A display device prevents breakage due to overheating of a data driver and a signal controller. The display device includes a display panel including a plurality of gate lines, a plurality of data lines and pixels connected to the gate lines and the data lines. A gate driver supplies a gate signal to the gate lines. A data driver supplies a data signal to the data lines. A signal controller controls the gate signal and the data signal. The signal controller includes a data converter converting a gray value of image data when a difference in the gray value of the image data of two adjacent pixels connected to the same data line among the plurality of data lines is greater than or equal to a first threshold value.
