    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 apparatus includes first pixels, second pixels, a gate driver, and a data driver. The first pixels receive data voltages in response to gate signals. The second pixels are alternately arranged with the first pixels in row and column directions and receive the data voltages in response to the gate signal. The gate and data drivers provide the gate and data signals, respectively, to the first and second pixels. Dual-gate signals each including two sub-gate signals having a same phase as each other are sequentially applied to the first and second pixels in the unit of two rows of odd-numbered rows and in the unit of two rows of even-numbered rows as the gate signals in a three-dimensional mode.
