Abstract
Disclosed is an LCD device. The LCD device includes a panel in which a plurality of gate lines cross a plurality of data lines, a source driving IC configured to alternately output a current data voltage and a current common voltage, a common electrode connected to the source driving IC through at least two or more common voltage lines, and a timing controller configured to generate current image data used to generate the current data voltage and common voltage data used to generate the current common voltage to be outputted to the source driving IC in correspondence with the current data voltage.
Claims11
A liquid crystal display (LCD) device comprising:
- a panel in which a plurality of gate lines cross a plurality of data lines;
- a source driving IC configured to alternately output a current data voltage and a current common voltage;
- a common electrode connected to the source driving IC through at least two or more common voltage lines;
- and
- a timing controller configured to generate current image data used to generate the current data voltage and common voltage data used to generate the current common voltage to be outputted to the source driving IC in correspondence with the current data voltage.
A method of driving an liquid crystal display (LCD) device, the method comprising:
- generating a current image data by using a current input image data and a current common voltage data corresponding to the current image data;
- converting the current image data into a current data voltage and outputting the current data voltage to a corresponding data line;
- and
- generating a current common voltage from the current common voltage data to a common electrode before or after the outputting the current data voltage to the corresponding data line.
