Display panel and driving method thereof and display device

Abstract

The embodiment of the invention provides a display panel and a driving method thereof and a display device, relates to the technical field of display, and can solve problems in the prior art that reduction of driving power consumption is unobvious and screen flashing occurs when static frames and dynamic frames are driven by different frequencies. The display panel comprises grid lines, data lines, pixel units, additional signal lines, a driving source and pixel driving circuits. Whether all the pixels units are dynamic pixels or static pixels is confirmed by the driving source before displaying of one frame. The static pixels include first static pixels and second static pixels. The first static pixels are driven by first frequency, the dynamic pixels are driven by second frequency, and the second static pixels are driven by third frequency. The pixel driving circuits start and charge the pixel units. A preset distance is reserved between the dynamic pixels and the first static pixels. The third frequency is greater than the first frequency and less than the second frequency.

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 of picture, generally, a driving signal with a certain frequency such as 60 Hz can be used to scan the gate line from top to bottom row by row, so that the above pixel units are turned on row by row. In this case, the data lines can charge the turned-on pixel units, so as to control the liquid crystal molecu...
