Abstract
A liquid crystal display includes a frame rate control (FRC) device which adds an FRC compensation value to digital video data using a plurality of FRC patterns defining subpixels, to which the FRC compensation value will be written, and a data driving circuit which converts the digital video data received from the FRC device into a data voltage and invert a polarity of the data voltage based on a previously determined inversion method. The FRC device counts frame periods and increases a frame count value each time the frame period changes. The FRC device changes to a next FRC pattern in previously determined order in response to the frame count value, and holds or skips the frame count value when the frame period reaches a previously determined time.
