Method of driving liquid crystal display device and liquid crystal display device

A method of driving a liquid crystal display device including a plurality of picture elements arranged in horizontal and vertical directions, and a display signal feeding pan which receives input of a video signal and feeds a display signal to each of the plurality of picture elements,

• wherein the display signal feeding part determines the gray level and polarity of a display signal to be fed to each picture element in accordance with a bright and dark display pattern and a polarity pattern;
• the bright and dark display pattern indicates the arrangement corresponding to one frame of bright display picture elements, each of which undergoes bright display through a supply of a first display signal having a higher gray level than a gray level of the video signal, and dark display picture elements, each of which undergoes dark display through a supply of a second display signal having a lower gray level than the gray level of the video signal;
• and the polarity pattern indicates the arrangement corresponding to one frame of positive-polarity picture elements, each of which receives the supply of a display signal of positive polarity, and negative-polarity picture elements, each of which receives the supply of a display signal of negative polarity;
• in the bright and dark display pattern, the bright display picture elements and the dark display picture elements alternate with each other every one picture element in the horizontal and vertical directions;
• and
• in the polarity pattern, the positive-polarity picture elements and the negative-polarity picture elements alternate with each other every two picture elements in the horizontal and vertical directions,
• wherein half of the positive-polarity picture elements and half of the negative-polarity picture elements are replaced with each other for each frame.

A liquid crystal display device comprising:

• a liquid crystal display panel having an arrangement of a plurality of picture elements;
• a plurality of gate bus lines and a plurality of data bus lines, which are disposed on the liquid crystal display panel and are connected to the picture elements;
• a display controller which receives input of a video signal and outputs a display signal;
• a gate driver which feeds a scan signal to the plurality of gate bus lines in sequence;
• a first data driver which feeds a display signal to odd-numbered data bus lines;
• and
• a second data driver which feeds a display signal to even-numbered data bus lines;
• wherein the display controller feeds display signals, which have different polarities, every two picture elements in one frame and have different gray levels every one picture element in the one frame, to the plurality of picture elements through the first and second data drivers.
