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: Provided is a display device comprising at least one sensing pixel including a sensing pixel circuit, a sensing unit including sensing circuit, and a temperature output unit to calculate a temperature of the display panel based on the sensing data. The sensing data is generated from a sensing pixel including a driving transistor in which a current generated according to temperature varies, and a temperature is measured from the sensing data.
