Abstract

The invention discloses a display panel, a display device and a driving method of the display panel, and belongs to the technical field of display. The display panel comprises a plurality of scan lines and a plurality of data lines, wherein the plurality of scan lines comprises a plurality of scan line groups, each scan line group includes a first scan line and a second scan line; and one scan line of one scan line group is electrically connected to one scan line of another scan line group through a connection portion. By electrically connecting the scan lines, it is possible to ensure lower leakage current. The switches of the display panel are alternately turned on during hold time so as to effectively prevent a certain column of switches using transistors from generating characteristicshift due to being in the same voltage state for a long time, thereby improving the display performance of the display panel and the display quality of the display panel.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display panel, a display device, and a driving method for the display panel. Background technique [0002] In the display panel provided by the prior art, even if the display panel needs to display the same picture for a long time, the driving circuit still continuously transmits scanning signals to the scanning lines, and the power consumption of the display panel is very large. In order to solve the above problems, a solution provided by the prior art is to display the same picture in a hold mode, without continuously transmitting scanning signals to the scanning lines, thereby reducing the power consumption of the display panel. However, in this way, the thin film transistor switches on the display panel will be in the same voltage state for a long time, causing the characteristics of the thin film transistor switches to drift, thereby causing leakage. Co...
