Liquid crystal display device and driving method thereof

A method for driving a liquid crystal display, comprising:

• supplying, by a data driver, a data voltage corresponding to each pixel by a unit of a pixel row;
• supplying, by a gate driver, a scan signal allowing input of the data voltage to the pixel by the unit of the pixel row;
• and
• displaying, by a display unit, a display image corresponding to the data voltage including a plurality of first rows of pixels and second rows of pixels that are alternately arranged;
• wherein the gate driver supplies a same scan signal to the plurality of pixels of a first row and a second row adjacent to each other among the plurality of first rows of pixels and the plurality of second rows of pixels at a first frame period, and respectively supplies a plurality of scan signals to only the plurality of second rows of pixels at a second frame period subsequent to the first frame period;
• and
• the data driver generates a plurality of data voltages respectively corresponding to the plurality of first rows of pixels at the first frame period and generates a plurality of data voltages respectively corresponding to the plurality of second rows of pixels at the second frame period.

A display device comprising:

• a plurality of gate lines and a plurality of data lines;
• a liquid crystal display including a plurality of pixels arranged in a plurality of first rows and second rows that alternate, and each pixel includes a switching clement connected to one or more of the plurality of gate lines and one or more of the plurality of data lines;
• a gate driver that is configured at a first frame period to output to a pair of adjacent rows of pixels via at least one of the gate lines a first scan signal comprising one of the first rows of pixels and one of the second rows of pixels to generate a first frame image, and the gate driver outputs at a second frame period a second scan signal to one row of the pair of adjacent first and second rows of pixels to generate a second frame image;
• a data driver that at the first frame period generates a plurality of data voltages respectively corresponding to the plurality of first rows of pixels, and the data driver generates at the second frame period a plurality of data voltages respectively corresponding to the plurality of second rows of pixels;
• and
• a timing controller configured to generate a first data image signal and a second data image signal, wherein the second data image signal is corrected using the first data image signal,
• wherein the data driver supplies by the plurality of data lines data voltages corresponding to the first and second rows of pixels.
