    Abstract: A display device includes a display panel including a plurality of pixels, an image data corrector configured to generate a corrected image data by adjusting an image data and a data driver providing data signals to the plurality of pixels based on the corrected image data. The image data corrector divides the display panel into a plurality of unit areas, and adjust the image data for a unit area among the plurality of unit areas by using a full image load for the entire display panel, a first image load for the unit area, and a second image load for peripheral unit areas surrounding the unit area among the plurality of unit areas.

    Abstract: A gate driving circuit includes driving stages for providing gate signals to gate lines of a display panel. A k-th driving stage a k-th driving stage (k being equal to or greater than 2) among the driving stages includes a gate output unit configured to output a clock signal as a k-th gate signal in response to a voltage of a first node, a carry output unit configured to output the clock signal as a k-th carry signal in response to the voltage of the first node, a control unit configured to control a voltage level of the first node in response to a (k−1)th carry signal, a first discharge unit configured to discharge the k-th carry signal to a voltage level in response to the (k−1)th carry signal, and a second discharge unit configured to discharge the k-th carry signal to a voltage level in response to a discharge signal.

    Abstract: A display device includes: a display panel; and a frequency controller which receives an image data signal and an input frequency information and outputs the image data signal and a timing control signal. The frequency controller includes: an image processor which receives the image data signal; a frame memory which stores the image data signal; an output frequency determining unit which receives the input frequency information and determines an output frequency based on a variation amount of the input frequency; and an image output unit which receives the image data signal from the image processor, receives an output frequency information from the output frequency determining unit, and outputs the image data signal and the timing control signal. When an input frequency varies, the output frequency determining unit determines the output frequency based on the following equations: K =  FREQ - P_FREQ M_FREQ  × SLOPE + OFFSET , and FREQ ′ = FREQ × K + P_FREQ × ( 1 - K ) .

    IPC: G09G3/36

    Abstract: A display apparatus includes a timing controller, a data driver and a display panel. The timing controller generates a mode selection signal and output image data in response to input image data. The data driver generates first through N-th data voltages in response to the mode selection signal and the output image data and applies the first through N-th data voltages to first through N-th data lines. The display panel is connected to the first through N-th data lines. During the first operation mode, each of a polarity pattern of first through M-th data voltages and a polarity pattern of (M+1)-th through N-th data voltages repeats a first polarity pattern. During the second operation mode, the polarity pattern of the first through M-th data voltages repeats the first polarity pattern, and the polarity pattern of the (M+1)-th through N-th data voltages repeats a second polarity pattern.
