Abstract
A liquid crystal display comprises a power supply, a pulse adjustment circuit, and a gate driver. The pulse adjustment circuit is connected between the power supply and the gate driver. The power supply provides power signals. The pulse adjustment circuit adjusts the plurality of pulses of the power signals or selects the appropriate voltage levels for the power signals to have cutting angles or enlarged amplitudes, whereby the influence of the feedthrough voltage on the thin film transistors of the driving circuit would be reduced so that the display quality of the liquid crystal display is improved.
