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.

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.

Abstract: A display apparatus includes a display panel having fan-out lines, data lines, a first dummy line, and a second dummy line. The fan-out lines are sequentially disposed along a first direction. The data lines are connected to the fan-out lines at first through nodes. The first dummy line is connected to one of the nodes. The second dummy line is connected to another of the nodes. A first data driver is configured to output data voltages to some of the fan-out lines based on a data signal. A second data driver is configured to output voltages to other fan-out lines based on the data signal. A timing controller is configured to compensate the data signal based on a voltage of nodes that the dummy lines are connected to.
