Abstract

The invention provides a display panel and a drive method of the display panel. The display panel comprises a thin film transistor (TFT) array substrate, the TFT array substrate comprises a plurality of scanning lines and a plurality of data lines, and the plurality of scanning lines and the plurality of data lines cross and limit a plurality of pixel units; each pixel unit comprises a TFT switch, a pixel electrode and a storage capacitor, grids of the TFT switches are connected with the scanning lines, source electrodes of the TFT switches are connected to the data lines, and drain electrodes of the TFT switches are connected to the pixel electrodes; a refresh rate of a scanning signal is less than 50 hertz, each frame scanning signal is divided into a signal updating stage and a picture maintaining stage, capacitance of the storage capacitor meets a preset value, picture display is guaranteed to maintain in the picture maintaining stage after the signal update stage of a current frame scanning signal is completed and before the signal update stage of a next frame scanning signal comes, wherein a data signal is input into the display panel in the signal updating stage, and no data signal is input into the display panel in the picture maintaining stage. The technical scheme is capable of reducing power consumption.

Description

technical field [0001] The invention relates to the display field, in particular to a display panel and a driving method thereof. Background technique [0002] With the development of the information society, people's demand for display devices has increased. In order to meet this requirement, several flat panel display devices such as thin film transistor liquid crystal display (TFT-LCD) and plasma display device (PDP) have been developed rapidly recently. Among flat-panel display devices, thin-film transistor liquid crystal display devices are gradually occupying a dominant position in flat-panel displays due to their advantages of low weight, small size, and low energy consumption. [0003] With the development of liquid crystal display technology, existing liquid crystal display panels include transmissive liquid crystal display panels, reflective liquid crystal display panels and transflective liquid crystal display panels. The transmissive liquid crystal display pane...
