    Abstract: A display device includes a display panel including a plurality of pixels, a current sensor that senses a sensing current that flows through the pixels, and a data compensator. The data compensator calculates a target current from an image frame of input image data using a current deviation for each position of the image frame and a current contribution ratio for each color of the image frame, and that generates a scale factor by comparing the target current and the sensing current. The display device further includes a timing controller that generates output image data by scaling grayscale values of the input image data using the scale factor; and a data driver that provides a data signal corresponding to the output image data to the pixels.

    Abstract: A display device includes a display panel and a display panel driver. The display panel includes pixels. The display panel driver determines an average image load of input image data, determines an operation mode based on a grayscale value of the input image data and the average image load as a first operation mode or a second operation mode, applies a first scale factor to the input image data in the first operation mode, applies a second scale factor different from the first scale factor to the input image data in the second operation mode, and drives the display panel.

    Abstract: 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.

    Abstract: 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.

    Abstract: A display device includes pixel patterns to display an image. Each pixel pattern is repetitively arranged in row and column directions, including primary pixels, first complex pixels and second complex pixels. Each primary pixel is composed of two primary color sub-pixels configured to provide two primary colors of three primary colors, wherein the three primary colors comprise red, green and blue. Each first complex pixel is composed of one primary color sub-pixel configured to provide a remaining primary color of the three primary colors and a first non-primary color sub-pixel configured to provide a first color selected from non-primary colors, wherein the non-primary colors are different from the three primary colors. Each complex pixel is composed of one primary color sub-pixel configured to provide the remaining primary color and a second non-primary color sub-pixel configured to provide a second color selected from the non-primary colors.
