    Abstract: A display device includes four pixel arrays, a data driver, and a demultiplexer. The data driver is electrically connected to first and second data output lines. The demultiplexer electrically connects first and second data lines to the first data output line and electrically connects third and fourth data lines to the second data output line. The first to fourth pixel arrays are adjacent to the first to fourth data lines, respectively. Each of the first to fourth pixel arrays includes first and second color pixels. The first color pixels in the second pixel array are connected to the second data line, the second color pixels in the second pixel array are connected to the third data line, the second color pixels in the third pixel array are connected to the third data line, and the first color pixels in the third pixel array are connected to the second data line.

    Abstract: A display apparatus includes a display panel, a gate driver, a data driver, a driving controller and a power voltage generator. The display panel displays an image based on input image data. The gate driver outputs a gate signal to a gate line. The data driver outputs a data voltage to a data line. The driving controller drives display areas of the display panel in different driving frequencies. The power voltage generator outputs a data power voltage to the data driver. The driving controller outputs an output data enable signal including a writing period having an active signal and a holding period having an inactive signal for the respective display areas. The power voltage generator generates the data power voltage having a high power voltage level during the writing period and a low power voltage level in at least a portion of the holding period.

    Abstract: A display device includes a display panel which includes first to nth pixel areas arranged in a direction, where n is a natural number greater than or equal to 2, an emission control driver which provides an emission control signal having a plurality of emission cycles corresponding to a number of outputs of a gate-on voltage during a frame period to the first to nth pixel areas, a power supply which generates first to nth bias voltages respectively provided to the first to nth pixel areas, and a timing controller which controls timings when the first to nth bias voltages are supplied to the first to nth pixel areas in a way such that a kth bias voltage is provided with a delay of one emission cycle from a (k−1)th bias voltage, where k is a natural number greater than or equal 2 and less than or equal n.
