Claim 0:
1. A liquid crystal display (LCD), comprising:
a thin film transistor (TFT) array, comprising a plurality of TFTs;
a gate driver, configured to provide a scan signal;
a source driver, configured to provide a data signal; and
a timing controller, electrically connected to the gate driver and the source driver, configured to calculate a vertical blank interval, to adjust a current refresh frequency according to a current frame rate, and to transfer a control signal to the gate driver when the current refresh frequency is lower than a threshold frequency and the vertical blank interval is longer than a threshold time period such that the gate driver increase a charging time of the plurality of TFTs according to the control signal.
