Pixel driving circuit, driving method thereof, and pixel matrix

摘要

A pixel driving circuit is electrically coupled between a first data line and a second data line and between a first scan line and a second scan line, and includes a first switch, a second switch, a third switch, a fourth switch, a liquid crystal capacitor electrically connected between the first switch and the second switch, a first capacitor electrically connected to the first switch, a second capacitor electrically connected to the second switch, a first storage capacitor, a second storage capacitor and at least one switching unit. The first storage capacitor is electrically connected to the third switch and supplied by a reference voltage. The second storage capacitor is electrically connected to the fourth switch and supplied by the reference voltage. The at least one switching unit is used for redistributing charges in the pixel driving circuit.
