Classification: CPC G | IPC G

Claim 5:
6. A method for compensating current leakage of a liquid crystal display (LCD) that comprises a thin film transistor (TFT) array having 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, the method executable by the timing controller comprising:
adjusting a current refresh frequency according to a current frame rate;
calculating a vertical blank interval; and
transferring 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 increases a charging time of the plurality of TFTs according to the control signal.
