Abstract

The invention discloses a drive circuit of a display panel, a drive method and the display panel. The drive circuit of the display panel, the drive method and the display panel are used for solving the problem that power consumption is large when data line is transformed between a high electrical level and a low electrical level. The drive circuit comprises a plurality of rows of data lines, and the drive circuit further comprises a discharge unit, a controllable switch unit and a discharge control unit, wherein the controllable switch unit is respectively and mutually connected with each row of the data lines, receives discharge control signals from the discharge control unit, and achieves the connection or disconnection between each row of the data lines and the discharge unit according to the control of the discharge control signals. The discharge unit is connected with the controllable switch unit, and used for enabling each row of the data lines to discharge when each row of the data lines are connected with the discharge unit.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a driving circuit of a display panel, a driving method thereof, and a display panel. Background technique [0002] As the screens of mobile terminals become larger and larger, reducing power consumption and extending standby time has become a focus of attention. In order to prevent the polarization of liquid crystal molecules, LCD (liquid crystal display) is driven with opposite polarity voltage, which is the so-called polarity inversion driving method. Commonly used polarity inversion driving methods include frame inversion, row inversion, column inversion, and dot inversion. In particular, column inversion and dot inversion driving methods are widely used in the TFT-LCD (Thin Film Transistor Liquid Crystal Display) industry due to their advantages such as high image quality. However, when the polarity inversion driving method is used, when two adjacent frames o...
