Display panel driving device and method

The embodiment of the invention provides a display panel driving device and method.The display panel driving device comprises a plurality of scanning lines, a plurality of data lines, a plurality of thin film transistors arranged in an array and a gate driving circuit, each thin film transistor is connected to one data line and one scanning line, and the gate driving circuit is connected to the data lines and the scanning lines. The gate driving circuit is connected with all or part of the scanning lines and is used for outputting gate driving signals based on N clock signals with phase difference to drive the corresponding scanning lines so as to activate the thin film transistors in the corresponding rows, N is an integer greater than or equal to 2, and N is an integer greater than or equal to 2; the gate drive circuit is configured to output gate drive signals in the mode that the corresponding N rows of scanning lines are driven on the basis of N clock signals in each round, and in the driving process of
