The embodiment of invention provides a display panel, a driving method thereof and a display device, and relates to the technical field of display. The problems that when a static image and a dynamic image are driven through different frequencies in the prior art, driving power consumption cannot be reduced obviously, and screen flash happens can be solved. The display panel further comprises a plurality of additional signal lines, a driving source and pixel driving circuits. The driving source is connected with grid lines and the additional signal lines, and is used for determining whether pixel units are dynamic pixels or static pixels in preset time before a frame of image is displayed. The driving source drives the pixel driving circuits of the static pixels at the first frequency through the additional signal lines and / or the grid lines and also drives the pixel driving circuits of the dynamic pixels at the second frequency through the additional signal lines and the grid lines. The pixel driving circuits are connected with data lines, the grid lines and the additional signal lines, and are used for being driven by the grid lines and the additional signal lines to be started and further charging the pixel units through the data lines.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a driving method thereof, and a display device. Background technique [0002] TFT-LCD (ThinFilmTransistorLiquidCrystalDisplay, Thin Film Transistor Liquid Crystal Display), as a flat panel display device, is more and more used in high performance display field. [0003] The array substrate of the TFT-LCD includes a plurality of gate lines and data lines intersecting horizontally and vertically, and a plurality of pixel units arranged in a matrix form are defined by intersections of the gate lines and data lines. In the process of displaying a frame, generally a certain frequency such as 60 Hz can be used to scan the gate line from top to bottom line by line, so that the TFTs in the above pixel units are turned on line by line. In this case, the data line can charge the pixel unit where the TFT is located through the turned-on TFT, so as to control the ...
