Abstract

The invention discloses a driving method of a display panel, and a display device. The driving method of the display panel belongs to the technical field of display, the display panel comprises a plurality of scanning lines, a plurality of data lines and a plurality of pixel units arranged in an array, the driving method comprises the following steps: in a first driving mode, two frames are takenas a polarity reversal driving period, and in one polarity reversal driving period, the polarity arrangement modes of two adjacent frames are the same and the polarities are opposite; in the second driving mode, at least 2n frames are taken as a polarity reversal driving period, and in the polarity reversal driving period, the polarity arrangement modes of the first frame to the nth frame are thesame, and the polarities are also the same; the polarity arrangement modes from the (n + 1) th frame to the (2n) th frame are the same, and the polarities are also the same; the polarity arrangement modes of the first frame and the (n + 1) th frame are the same, and the polarities are opposite. The driving method can be compatible with high-frequency driving and low-frequency driving modes, is suitable for switching operation of various different driving frequencies, and is favorable for saving power consumption, meeting the charging time and improving the charging efficiency.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a driving method of a display panel and a display device. Background technique [0002] Liquid Crystal Display (LCD) has many advantages such as thin body, power saving, and no radiation, and has been widely used, such as LCD TV, mobile phone, personal digital assistant (PDA), digital camera, computer screen or notebook Computer screens, etc., dominate the field of flat panel displays. [0003] The liquid crystal display panel includes a plurality of sub-pixels arranged in an array, each sub-pixel is electrically connected to a thin film transistor (TFT), the gate (Gate) of the TFT is connected to the gate scanning line in the horizontal direction, and the source (Source ) is connected to the data line in the vertical direction, and the drain (Drain) is connected to the pixel electrode. Applying sufficient voltage on the gate scanning line through the gate dri...
