  • Patent number: 10497329
    Abstract: A display device and a method of driving the same. The display device includes a display panel on which a plurality of data lines and a plurality of gate lines intersect each other to form a matrix, with a number of pixels being defined at intersections of the plurality of data lines and the plurality of gate lines. A data driver is connected to the plurality of data lines. A gate driver is connected to the plurality of gate lines. A timing controller controls the display panel to operate in a driving mode that changes depending on image signals.
