A liquid crystal display device includes a liquid crystal panel configured to display an image, a driver configured to drive the liquid crystal panel, a timing controller configured to control the driver, and a power supply configured to be supplied by an input voltage, supply a common voltage to the liquid crystal panel, and temporarily vary a compensation ratio of the common voltage when a pattern causing a drop of the input voltage is displayed by the display device.

A method of driving a display panel includes generating a reference gate signal delayed by a predetermined period from a gate signal applied to a gate line disposed in a first end area of the display panel, the first end area being an area in which a RC delay of a data line is the smallest, receiving an input gate signal applied to a gate line disposed in a second area of the display panel, the second area being an area in which the RC delay of the data line is the largest; and selectively controlling a delay time of each of the plurality of gate signals applied to each of the plurality of gate lines according to a result of comparison between the reference gate signal and the input gate signal.

The present disclosure discloses a gate driving method, a driving apparatus of a display panel and a display apparatus. The driving apparatus may be in two driving modes, i.e., a first mode and a second mode. In the first mode, due to a reduced number of gate lines to be driven when various frames of images are displayed, the power consumption can be reduced. In addition, due to the effect of persistence of vision of human eyes, better quality of display images can be ensured while reducing power consumption. In the second mode, as respective lines of gate lines are driven progressively when various frames of images are displayed, the display panel is enabled to have better quality of display images. By switching the driving apparatus between the first mode and second mode, a number of gate lines to be driven can be reduced so as to reduce power consumption.
