Display driving circuit and driving method of the circuit

The present invention discloses a driving method and a display drive circuit for the minimum current consumption to a minimum, while the residual image on the display panel. To the display drive circuit, the valid data and black data with generating drive signals corresponding to, and transmitted to the display panel, N (N is an integer) pieces of data selection switch, N buffers, N of the buffer output selection switches and a plurality of charge and a distribution switch. The N data-selection switch selects one of the valid data and the black data. The N buffer buffers the signal selected by the data select switch, respectively. The N buffer output selection switches and outputs the drive signal to switch the output of the buffer. The plurality of the charge sharing switch connects to each other the two drive signals for the neighborhood. Removing an afterimage, the valid data and black data, the charge sharing
