Patent number: 10777162Abstract: A display apparatus includes a display panel, a timing controller, a data driver and a voltage generator. The display panel includes a switching element, a pixel electrode connected to the switching element, a common electrode, a storage electrode and a pixel electrode. The timing controller processes input image data according to a variable frame rate and generates a data signal having a variable frame length. The data driver converts the data signal into a data voltage and outputs the data voltage to the pixel electrode. The voltage generator may apply a common voltage to the common electrode and a storage voltage greater than the common voltage to the storage electrode, and/or apply the common voltage varied according to a grayscale value of the input image data. Embodiments may reduce or obviate a display defect caused by luminance differences between frames displayed at different frame rates.Type: GrantFiled: December 21, 2018Date of Patent: September 15, 2020Assignee: SAMSUNG DISPLAY CO., LTD.Inventors: Kang-Woo Kim, Beomjun Kim, Changjung Kim, Seongyeol Syn, Gwon-Heon Ryu
