Patent ID: 8427408

Claim:
A liquid crystal display device comprising: a liquid crystal panel comprising a plurality of gate lines and a plurality of data lines crossing each other; a data driver that selectively applies image data and charge share voltage data; a gate driver that supplies a first scan signal to display the image data and a second scan signal to display the charge share voltage data on the liquid crystal panel; and a timing controller for generating a first control signal including a gate shift control signal, a gate start pulse and a gate output enable signal and a second control signal including a source shift control signal, a source start pulse and a source output enable signal, wherein the data driver comprises a data voltage generator operable to generate the image data and a selection unit operable to select one of the image data or the charge share voltage data, wherein the charge share voltage data is generated by shorting the adjacent data lines and has an average voltage value based on the image data, wherein the one of the image data or the charge share voltage data is selectable by the source output enable (SOE) signal that controls an output of the data driver, wherein the selection unit comprises first switches disposed between the plurality of data lines and second switches different from the first switches disposed along the plurality of data lines, each switch of the first switches respectively coupled with two adjacent data lines of the plurality of data lines and each switch of the second switches respectively coupled in series with each data line of the plurality of data lines, and the first and second switches conversely operate with each other and are controlled by the source output enable (SOE) signal, wherein the first scan signal and the second scan signal are sequentially supplied respectively to one gate line among the plurality of gate lines and to another gate line among the plurality of gate lines other than the one gate line.
