Display panel driving circuit, driving method thereof, and display device

摘要

Embodiments of the present invention provide a driving circuit for a display panel which comprises a plurality of pixel units defined by intersected gate lines and data lines and arranged in a matrix form, a driving method of a display panel driving circuit and a display device, relating to the field of display technology. The display panel driving circuit includes pixel charging units, each of which is used for combining voltages outputted from a clock pulse vertical terminal and a data voltage signal terminal to serve as a driving voltage for a data line to increase the charging voltage of pixel units, so that the charging time is shortened, and the capability of driving a display panel load can be enhanced.
