Abstract

The invention provides a driving method for a display panel, a time sequence controller and a liquid crystal display. The method comprises the steps of: when detecting a picture frame to be displayed is a reloaded picture, switching the working frequency from a first frequency to a second frequency by the time sequence controller; and outputting a time sequence control signal to a source driver by using the second frequency, so that the source driver outputs a driving signal with lower frequency to drive displaying of the reloaded picture, wherein the first frequency is higher than the second frequency. The driving method can avoid too high output power consumption of the source driver when the reloaded picture is displayed and avoid temperature rise to influence the display quality.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a driving method of a display panel, a timing controller and a liquid crystal display. Background technique [0002] Currently, the most commonly used liquid crystal display is a thin film transistor (Thin Film Transistor, TFT) liquid crystal display. The TFT liquid crystal display adopts a source driver (Source Driver) to provide a driving voltage corresponding to an image to be displayed to the data line, so as to drive the display panel to display images. [0003] However, if the liquid crystal display needs to display a heavy-duty picture, that is, the power consumption of the source driver is too large when driving the heavy-duty picture, at this time, the output power consumption required by the source driver to form and maintain the driving voltage becomes larger , At the same time, according to the driving mode of the general liquid crystal display, the switching freque...
