Patent number: 11682336Abstract: A display apparatus includes a display panel, a driving controller and a data driver. The driving controller processes input image data according to a variable input frequency and generates a data signal having a varied frame length. The data driver converts the data signal into a data voltage and outputs the data voltage to the display panel. The driving controller determines a variable frequency mode and generates an asymmetric data signal including a positive data signal and a negative data signal which are asymmetric with respect to a common voltage for a same grayscale value in the variable frequency mode.Type: GrantFiled: March 11, 2021Date of Patent: June 20, 2023Assignee: SAMSUNG DISPLAY CO., LTD.Inventors: Tae Hyeong An, Hoi Sik Moon, Yoon Gu Kim, Jin Pil Kim, Jae Sung Bae, Nam Jae Lim, Ik Hyun Ahn, Seung Young Choi
