Abstract
The present disclosure provides a pixel unit driving circuit, a driving method and a display apparatus. According to the present disclosure, pixel units in a panel are designed to use switch elements of the pixel units made of NMOS transistors and PMOS transistors alternately. That is, the switch elements connected to scan signal lines and data lines use NMOS transistors and PMOS transistors alternately in the horizontal (vertical) direction. In conjunction with a scan timing sequence, a high-low level time division scan technique can be adopted to allow the voltage difference between the data lines and the pixel electrodes to vary alternately between positive and negative.
