Liquid Crystal Display Device and Driving Method

摘要

A liquid crystal display device includes a first voltage source providing a first voltage; a second voltage source providing a second voltage greater than the first voltage; and a switching unit arranged at a connection between a gate terminal of a first TFT and a scan line. The switching unit has a control terminal electrically connected to the scan line, an input terminal electrically connected to the first voltage source, and an output terminal electrically connected to the second voltage source and a common electrode of a storage capacitor of a pixel unit. When the switching unit receives a scan signal, the first voltage source supplies the first voltage to the common electrode of the storage capacitor of the pixel unit. When no scan signal is received, the second voltage source supplies the second voltage to the common electrode of the storage capacitor of the pixel unit.
