Abstract: 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.

Abstract: A display apparatus includes a display panel, a driving controller and a data driver. The display panel is configured to display an image. The driving controller is configured to generate a compensated image data for compensating a decrease of a luminance of an edge portion of the display panel based on input image data. The data driver is configured to output a data voltage to the display panel based on the compensated image data. The driving controller is configured to generate the compensated image data by comparing a maximum value among subpixel grayscale values of the input image data to which a luminance compensating coefficient is applied and a maximum grayscale value of the input image data. The luminance compensating coefficient is configured to be determined according to a location in the display panel.

Abstract: A display device includes: a first display panel; a second display panel facing the first display panel and including an optical sensor; an electro-optical active layer positioned between the first display panel and the second display panel; and a sensing gate driver including a first sensing gate driver and a second sensing gate driver, the sensing gate driver configured to transmit a sensing gate signal to the optical sensor, in which a first sensing gate off voltage applied to the first sensing gate driver is substantially the same as a second sensing gate off voltage applied to the second sensing gate driver.
