    Abstract: A display apparatus includes a display panel, a driving controller, and a data driver. The display panel is configured to display an image based on input image data. The driving controller is configured to determine whether the input image data include a display quality deteriorating pattern. The driving controller is configured to determine a first compensation value for compensating a first area disposed at a first side of a main area of the display quality deteriorating pattern and a second compensation value for compensating a second area disposed at a second side of the main area opposite to the first side of the main area, according to a position of the main area. The data driver is configured to apply a data voltage to the display panel using the first compensation value and the second compensation value.

    Abstract: A display device includes a display panel which includes a pixel including a driving transistor and a light-emitting element, and a sensing line connected to the pixel. A sensing driver senses a first sensing signal corresponding to mobility of the driving transistor through the sensing line, and processes the first sensing signal to output first sensing data. A driving controller receives the first sensing data from the sensing driver, generates mobility compensation data and kickback compensation data based on the first sensing data, and converts image data into compensation image data by the mobility compensation data and the kickback compensation data. A data driver converts the compensation image data into a data signal and provides the data signal to the pixel.

    Abstract: A display device with a timing controller is disclosed. In one aspect the display includes first and second gate drivers, first and second gate lines extending in first and second directions from the first and second gate drivers, data lines extending in a third direction, a display panel including pixels connected to the first and second gate lines and the data lines, data driving circuits each driving corresponding data lines in response to an output start signal and a data signal, and a timing controller. The timing controller sets an output timing of the data signals according to a distance in the first direction between the first gate driver and the data driving circuits when the first gate lines are driven and sets an output timing of the data signals according to a distance in the second direction between the second gate driver and the data driving circuits when the second gate lines are driven.
