A driving method of a display device includes: generating output image data by the signal controller by either reducing vertical resolution of input image data of one frame by 1/k (k is a natural number) or receiving input image data with its vertical resolution reduced by 1/k and processing the input image data to generate output image data; generating a data voltage based on the output image data by the data driver to apply the data voltage to the data line; and applying gate-on voltage pulses to k adjacent gate lines by the gate driver corresponding to respective image data of the output image data, wherein the output image data corresponding to some pixel rows of the output image data are shifted to left or right by at least one pixel and are output to the data driver in a first frame.

An exemplary embodiment of the present disclosure provides a display device including: a substrate including a display area and a non-display area; a COF package overlapped with the non-display area of the substrate; a printed circuit board (PCB) overlapped with the COF package; a plurality of pixels disposed on the display area of the substrate; a plurality of data lines connected to the plurality of pixels; a first crack sensing line disposed on the non-display area of the substrate; a second crack sensing line that extends to be parallel to the first crack sensing line on the non-display area of the substrate and is connected to the first data line of the plurality of data lines; a first dummy wire that is disposed on the COF package and is overlapped with the first crack sensing line and the second crack sensing line; a first anisotropic conductive film disposed between the substrate and the COF package; a first test pattern and a second test pattern disposed on the PCB; a third test pattern that is disposed on the COF package and is overlapped with the first test pattern and the second test pattern; and a second anisotropic conductive film disposed between the COF package and the PCB.

Display device

A display device includes gate lines, data lines, pixels connected to the gate lines and data lines, a data driver, a gate driver, and a signal controller for controlling the data driver and gate driver. A method for driving the display device includes: compressing, by the signal controller, vertical resolution of input image data of each frame by k or receiving by the signal controller the compressed input image data; processing by the signal controller the compressed input image data to generate output image data; generating, by the data driver, data voltages based on the output image data and applying the data voltages to the data lines; and applying, by the gate driver, gate-on voltage pulses concurrently to k neighboring gate lines corresponding to the applied data voltages. Starting times of the gate-on voltage pulses of at least two of the k neighboring gate lines are different from each other.
