The present invention provides a pixel unit driving circuit, a driving method and a display apparatus. According to the present invention, rows of 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. In this way, the vertical cross-interference due to parasitic capacitance between the data lines and the pixel electrodes can be reduced.

The present invention provides a driving method and a driving circuit of a display panel and a display device. The display panel comprises: gate lines and data lines and pixel units, the data lines comprises: first data lines and second data lines, and a first predetermined number of first data line(s) and a second predetermined number of second data line(s) are alternately arranged. The driving method comprises a step of: scanning the gate lines in turn, wherein when scanning one gate line, a data voltage signal is applied to the first data lines or the second data lines. The driving method provided by the present invention can allow the pixel units on the OLED panel to display alternately, and since the area of each pixel unit is relatively small with respect to the area of the whole OLED panel, such alternate display manner has a relatively small effect on the image display quality of the OLED panel. Meanwhile, compared to the driving method in the prior art, the driving method provided by the present invention allows lower power consumption of the OLED panel when display at the same brightness is achieved.

The present disclosure discloses a gate driving method, a driving apparatus of a display panel and a display apparatus. The driving apparatus may be in two driving modes, i.e., a first mode and a second mode. In the first mode, due to a reduced number of gate lines to be driven when various frames of images are displayed, the power consumption can be reduced. In addition, due to the effect of persistence of vision of human eyes, better quality of display images can be ensured while reducing power consumption. In the second mode, as respective lines of gate lines are driven progressively when various frames of images are displayed, the display panel is enabled to have better quality of display images. By switching the driving apparatus between the first mode and second mode, a number of gate lines to be driven can be reduced so as to reduce power consumption.
