Abstract
A liquid crystal display (LCD) and a method for compensating current leakage of the LCD are provided. The LCD includes 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 electrically connected to the gate driver and the source driver. The timing controller is configured 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 such that the gate driver increase a charging time of the plurality of TFTs according to the control signal.
