    Abstract: A display device includes a display panel, a first circuit board, a control unit disposed on the first circuit board, a second circuit board, and a coupling film which electrically couples the control unit and the second circuit board to each other. The coupling film includes a first coupling part including a first region attached to the first circuit board, and a second region overlapping the display panel when viewed in a thickness direction of the display panel, a second coupling part including a third region attached to the second circuit board, and a fourth region overlapping the display panel when viewed in the thickness direction of the display panel, and a third coupling part coupled to each of the second region and the fourth region to electrically couple the first coupling part and the second coupling part to each other.

    IPC: G09G3/20

    Abstract: A display apparatus includes a display panel displaying an image based on an input image data, a data driver outputting a data voltage to a data line, and a driving controller determining a driving frequency of the display panel based on the input image data. The driving controller includes a flicker value storage configured to store flicker values for grayscale values corresponding to the input image data, a voltage drop determiner configured to adjust a flicker value of the flicker values based on a voltage drop of the display panel, a still image determiner configured to determine whether the input image data is a still image or a video image, and a driving frequency determiner configured to determine the driving frequency of the display panel using the flicker value based on the input image data being the still image.

    Abstract: A method of obtaining overdriving data includes providing a first data voltage corresponding to a current line reference gray level to a second pixel for first and second data writing times for first and second pixels in a first frame, measuring first luminance based on the first data voltage, applying a second data voltage corresponding to a previous line reference gray level for the first data writing time in a second frame, providing a third data voltage of an overdriving voltage corresponding to a predicted overdriving gray level added to the first data voltage for the second data writing time in the second frame, measuring second luminance based on the third data voltage, and determining an overdriving value corresponding to a reference gray level pair of the current and the previous line reference gray level as the predicted overdriving gray level when the first and second luminance are the same.

    IPC: G09G3/3258 ,  G09G3/3291

    Abstract: A display apparatus includes a display panel, a gate driver, a data driver and a driving controller. The display panel displays an image based on input image data. The gate driver outputs a gate signal to a gate line of the display panel. The data driver outputs a data voltage to a data line of the display panel. The driving controller is configured to control an operation of the gate driver and an operation of the data driver, to determine a driving mode of the display apparatus among one of a normal driving mode and a low frequency driving mode, and to determine a driving frequency of the display panel based on the input image data. The driving controller includes a flicker value storage configured to store flicker values for a part of grayscale values among all of grayscale values of the input image data.
