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.

Method of driving display panel and display apparatus

A liquid crystal display includes a liquid crystal panel that displays an image signal, a backlight unit supplying light to the liquid crystal panel, and a backlight control circuit to scan the backlight unit. The backlight control circuit supplies a pulse width modulation signal to rows of the backlight unit, which are adjacent to rows being scanned, such that the rows adjacent to the rows being scanned have a brightness lower than a brightness of the rows being scanned.

An apparatus for providing grayscale voltages and a display device using the same are provided. The display device includes a grayscale voltage provider that provides grayscale voltages using a first reference voltage and a second reference voltage in accordance with a selection signal. A data driver applies data voltages to data lines using the grayscale voltages and an image signal. A gate driver successively provides a gate-on voltage to the gate lines. A display panel displays an image for each frame using the data voltages and the gate-on voltage.
