摘要： A display apparatus includes first-kind data lines and second-kind data lines. Each of the first-kind data lines is connected to one of two pixels arranged in a k-th pixel row and a (k+1)th pixel row. Each of the second-kind data lines is connected to two pixels arranged in different pixel columns in the k-th pixel row and the (k+1)th pixel row. At least two first-kind data lines are consecutively arranged.

摘要： 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 column between a k-th data line and a (k+1)th data line. The pixels arranged in the k-th column are arranged in a plurality of groups, and each of the groups includes 2i first pixels connected to the k-th data line and 2i second pixels connected to the (k+1)th data line. Successive ones of the pixels in each group are connected to the k-th data line and the (k+1)th data line in alternating manner.

摘要： A display device includes a display panel, a driving controller, and a voltage generator. The display panel includes a plurality of pixels. Each of the pixels receives a driving voltage through a first voltage line. The driving controller receives an input image signal including first to third color signals and outputs a voltage control signal for controlling a voltage level of the driving voltage based on the first to third color signals. The voltage generator provides the driving voltage to the first voltage line and determines the voltage level of the driving voltage based on the voltage control signal. The driving controller determines first to third gate-source voltages respectively corresponding to the first to third color signals and outputs the voltage control signal based on the first to third gate-source voltages.

摘要： A display device includes a display panel, a luminance compensator, and a data driver. The display panel includes a plurality of pixels. The luminance compensator is configured to calculate a scaling factor based on a target current, a black image current, and a sensing current. The target current is calculated based on an input current input to the display panel. The sensing current is measured from the display panel. The data driver is configured to generate a data voltage based on input image data to supply the data voltage to the pixels. The data voltage has a voltage level adjusted based on the scaling factor.

摘要： 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.

摘要： A display apparatus includes a local dimmer, an image compensator, a display panel and a light source. The local dimmer is configured to generate a dimming signal representing a degree of dimming for a light source block based on input image data. The image compensator is configured to determine a grayscale gain based on input grayscale value of the input image data and the dimming signal and to compensate luminance of the input image data based on the grayscale gain. The display panel is configured to display an image based on the compensated input image data. The light source is configured to provide light to the display panel based on the dimming signal.

摘要： A display apparatus includes gate lines extending in a first direction, data lines crossing the first direction and having polarities of data voltages consecutively repeated every four data lines, and pixels which each comprise three sub-pixels. One of the three sub-pixels has a width in the first direction different from a width in the first direction of another sub-pixel of the three sub-pixels. Each of the three sub-pixels is connected to a corresponding gate line and a corresponding data line. The polarities of the data voltages applied to a first data line and a third data line are opposite and the polarities of the data voltages applied to a second data line and a fourth data line are opposite. The pixels arranged between two adjacent data lines among the plurality of data lines are alternately connected to the two adjacent data lines.
