摘要： A display apparatus includes a liquid crystal panel including gate lines, data lines, and pixels, a gate driver, a data driver, and a timing controller. The pixels include first and second pixels. The first and second pixels are arranged in pixel rows adjacent to each other, arranged in different pixel columns, connected to the same gate line, display the same color, and receive data voltages having different polarities from each other. The image data include first pixel data displayed in the first pixels and second pixel data displayed in the second pixels. When the first pixel data have a first grayscale value and the second pixel data have a second grayscale value different from the first grayscale value, the timing controller modulates the first and second pixel data to allow the first and second pixel data to have a grayscale value between the first and second grayscale values.

摘要： A display device includes a degradation compensator, a controller, a data driver, and a display panel. The degradation compensator generates a first fitting function and a second fitting function based on image data, generates a compensation function through a harmonic mean of the first and second fitting functions, and generates a compensation value based on the compensation function. The controller receives the compensation value, and generates input image data to which the compensation value is applied. The data driver receives the input image data to which the compensation value is applied, and converts the input image data into a data voltage. The display panel includes pixels, in which each of the pixels includes a pixel circuit which receives the data voltage and a light-emitting element electrically connected to the pixel circuit.

摘要： A display device includes a display panel, a plurality of sensors, a signal control unit, and a backlight unit. A plurality of dimming regions is defined in the display panel. The signal control unit determines a plurality of representative luminance values corresponding to the plurality of dimming regions based on image data signals received from an external device and illuminance values of an external light measured by the plurality of sensors. The backlight unit provides lights having the representative luminance values to the display panel.

摘要： According to an embodiment, a display apparatus includes gate lines extending in a first direction, data lines extending in a second direction crossing the first direction, and pixels connected to the gate lines and the data lines. The pixels include pixels arranged in a k-th row and pixels arranged in a (k+1)th row disposed adjacent to the pixels arranged in the k-th row in the second direction. An (i+1)th gate line is disposed between the pixels in the k-th row and the pixels in the (k+1)th row. A first pixel arranged in a g-th column among the pixels arranged in the k-th row and a second pixel arranged in the g-th column among the pixels arranged in the (k+1)th row are connected to a j-th data line. The pixels arranged in the k-th row are alternately connected to an i-th gate line and the (i+1)th gate line.
