Liquid crystal display and frame rate control method thereof

A frame rate control (FRC) method for a liquid crystal display, comprising:

• selecting a plurality of FRC patterns, which define subpixels, to which a FRC compensation value will be written, as subpixels of different positions, and adding a predetermined FRC compensation value to digital video data based on the selected FRC pattern;
• and
• converting the digital video data, to which the FRC compensation value is added, into a data voltage and inverting a polarity of the data voltage based on a previously determined inversion method to supply the data voltage to a pixel array of a liquid crystal display panel;
• wherein the adding of the predetermined FRC compensation value to the digital video data includes:
• counting frame periods and increasing a frame count value each time the frame period changes;
• and
• changing to a next FRC pattern in previously determined order in response to the frame count value and holding or skipping the frame count value when the frame period reaches a previously determined time.
