Abstract:
1. A display device comprising: a display panel that has a plurality of pixels that are divided by a plurality of gate lines arranged in a first direction and a plurality of data lines arranged in a second direction substantially perpendicular to the first direction; a timing controller configured to generate at least one gate control signal and a first source output enable signal; a gate driver configured to provide the gate lines with a plurality of scan signals in response to the at least one gate control signal; a pulse width controller configured to vary a pulse width of the first source output enable signal to generate a second source output enable signal that has a varied pulse width; and a data driver configured to output a data voltage to the data lines in response to a low level period of the second source output enable signal, and output a pre-charge voltage to the data lines in response to a pulse of the second output enable signal, wherein the pre-charge voltage is generated when the data lines are electrically connected to each other, wherein the second source output enable signal varies an output time of the data voltage and the pre-charge voltage from the data driver according to an average data of a present frame, wherein the pulse width of the second source output enable signal increases when a difference between a reference data and the average data is larger than a predetermined value, and the average data is obtained as an average value of data signals of pixels connected to a gate line or to a plurality of gate lines.
