Liquid crystal display apparatus and driving method therefor

A method for driving a liquid crystal display apparatus including a plurality of gate lines, a plurality of data lines electrically insulated from the gate lines and which extend along a different direction from that of the gate lines to define a plurality of pixel areas arranged in a matrix shape, and a plurality of pixels being formed in the pixel areas, the method comprising:

• providing the gate lines with scan signals, sequentially;
• comparing a first gradation datum of an (n)-th frame received from an image signal source with a second gradation datum of an (n+1)-th frame received from the image signal source to generate a compensated gradation datum of the (n)-th frame by adding a variable pre-tilt value to the first gradation datum when a gradation of the second gradation datum is higher than a gradation of the first gradation datum (wherein ‘n’ denotes a natural number greater than two);
• and
• providing the data lines with a data voltage that corresponds to the compensated gradation datum,
• wherein the pre-tilt value is not added to the first gradation datum when the gradation of the second gradation datum is lower or substantially equal to the gradation of the first gradation datum,
• the pre-tilt value is varied in accordance with the first gradation datum and the second gradation datum, and
• a level of the pre-tilt value is increased as a difference between the gradation of the second gradation datum and that of the first gradation datum is increased.
