Display driving circuit, driving method thereof and display apparatus

摘要

The present disclosure provides a display driving circuit, a driving method thereof, and a display apparatus, to solve the issue regarding power consumption of the display driver due to multiple reversal of the data voltage. The driving method comprises: firstly, determining pre-input data signals that are respectively input by a data line to each pixel unit of a column of pixel units corresponding to the data line when inputting a Nth image frame; next, determining, according to magnitudes or polarities of the pre-input data signals, a scanning order for the gate lines; then, scanning the gate lines according to the scanning order; and then, inputting the pre-input data signals to corresponding pixel units by the data lines.
