Abstract
The present invention provides a drive method of a liquid crystal display panel, in which the counter (21), and the pulse modulation module (22) are located in the sequence controller (2), and the counter (21) in the sequence controller (2) pluses 1 as the sequence controller (2) outputs the display data of each row, and as the counter (21) in the sequence controller (2) pluses to i×M/N, the pulse modulation module (22) in the sequence controller (2) sends one pulse control signal (CS) to the i+1th gate drive IC correspondingly driving the i+1th pixel display region (Zone(i+1)) to control the i+1th gate drive IC (GD(i+1)) to output the target TFT activation voltage corresponding to the i+1th gate drive IC (GD(i+1)) after the internal calculation and the conversion, and thus the TFT activation voltage can be dynamically adjusted in real time.
