Patent number: 11586334Abstract: A display device includes a display portion, a display driver, a touch sensing portion, and a touch driver. The display portion includes data lines, scan lines, and pixels connected to the data lines and the scan lines. The display driver provides data signals to the data lines and sequentially provides scan signals to the scan lines. The touch sensing portion includes sensing electrodes. The touch driver senses a touch input based on a change of a capacitance between the sensing electrodes and calculates a movement speed of the touch input. When the movement speed of the touch input is greater than a reference speed, a first period in which the scan signals and the data signals are provided is reduced in a frame period in which a frame image is displayed.Type: GrantFiled: May 3, 2021Date of Patent: February 21, 2023Assignee: SAMSUNG DISPLAY CO., LTD.Inventors: Ho Seok Son, Myoung Ho Kwon, Jeong Kug Lee
