摘要： A display device includes a display panel including gate lines, data lines, and pixels each connected to a corresponding gate line and a corresponding data line, a gate driver configured to drive the gate lines, a data driver configured to drive the data lines, and a timing controller configured to generate control signals to control the data driver and to apply a vertical synchronization start signal including a first pulse, a second pulse, a first gate pulse signal, and a second gate pulse signal to the gate driver. The gate driver applies gate driving signals to the gate lines to pre-charge the pixels in response to the first pulse of the vertical synchronization start signal and the first gate pulse signal, and to main-charge the pixels in response to the second pulse of the vertical synchronization start signal and the second gate pulse signal.

摘要： 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.

摘要： A display panel driver includes a timing controller and a data driver. The timing controller generates a data signal based on an input image data. The data driver receives the data signal, converts the data signal into a data voltage and outputs the data voltage to a display panel. The data signal includes positive data and negative data. The data driver includes a data skew compensating circuit which samples the positive data using the negative data and compensates a skew of the data signal.

摘要： A display device includes: a display panel including gate lines, a data lines crossing the gate lines, and pixels connected to the data lines and the gate lines; a data driver configured to drive the data lines; a gate driver configured to drive the gate lines in synchronization with a vertical sync start signal; and a timing controller configured to control the data driver and the gate driver in response to an image signal and a control signal inputted thereto from an outside, where the timing controller outputs the vertical sync start signal to the gate driver, and changes a frequency of the vertical sync start signal when an image signal of a current frame is identical to an image signal shifted from an image signal of a previous frame in a first direction.
