Abstract

The invention discloses a driving method, a driving circuit and a display device. The driving method is used for driving a display panel, and comprises the following steps: providing a source driving signal according to a first clock signal; and providing a control signal according to the shutdown signal, wherein after the shutdown signal is switched from the invalid state to the valid state, the control signal maintains a high level in a first stage and maintains a low level in a second stage, and in the second stage, the source electrode driving signal is switched to a high resistance state under the action of the control signal so as to stop charging the display panel. According to the driving method, part of residual charges are released in advance, complete release of the charges is facilitated, and the total time required by discharging is shortened.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, and more specifically, to a driving method, a driving circuit and a display device. Background technique [0002] Liquid Crystal Display (LCD) is a display device that uses the phenomenon that the alignment direction of liquid crystal molecules changes under the action of an electric field to change the light transmittance of the light source. Due to its advantages of good display quality, small size and low power consumption, liquid crystal displays have been widely used in display terminals such as mobile phones and large-sized display panels such as flat-panel televisions. [0003] When the liquid crystal display is turned off, there is still residual charge in the pixel unit where the liquid crystal molecules are located, and the residual charge will bring adverse effects such as after-image after shutdown. residual charge. In the prior art, in order to solve the prob...
