Abstract
Provided are a pixel driving circuit, a pixel driving method and a liquid crystal display device. Each pixel unit of the pixel driving circuit comprises a first sub pixel and a second sub pixel. A first sub pixel and a second sub pixel in a column of pixel units are respectively connected to one data line and one auxiliary line, and meanwhile, control units receiving the first and second control signals are arranged. Each control unit is coupled to an auxiliary line and a data line connected to a column of pixel units. The control unit is controlled by the first control signal and the second control signal to disconnect the data line from the auxiliary line and to connect the auxiliary line to the common electrode line, or to connect the data line to the auxiliary line and to disconnect the auxiliary line from the common electrode line.
