Abstract: A liquid crystal display and a driving method of the same are provided, and which drive scanning lines and data lines by a timing controller. When writing data signals to a liquid crystal capacitor, the timing controller controls a source driving circuit to provide the data signals to each data line, and control a gate driving circuit to generate a high-voltage signal to each scanning line in sequence. The high-voltage signals of two adjacent scanning lines overlap. When the high-voltage signals overlap, the timing controller transmits the data signal to each liquid crystal capacitor sequentially. After finishing writing data signals to the liquid crystal capacitor, the timing controller controls the gate driving circuit to generate a pulse signal to each scanning line continuously. The pulse signals generated by the scanning lines do not overlap. Accordingly, it can avoid the leakage of data signal stored in the liquid crystal capacitors.
