The embodiment of the invention discloses a driving method of a display panel, the display panel and a display device. The driving method comprises: a one-frame display picture of the display panel comprises a charging phase and a retention phase; if grey scale voltage applied to the same data line is greater than voltage of a public electrode in the charging phase of the one-frame display picture, the range of retention voltage V applied to the data line in the retention phase of the one-frame display picture is that V is more than or equal to VCOM+(VDH-VCOM) / 3 and smaller than or equal to VCOM+2(VDH-VCOM) / 3; if the grey scale voltage applied to the same data line is smaller than the voltage of the public electrode in the charging phase of the one-frame display picture, the range of the retention voltage V applied to the data line in the retention phase of the one-frame display picture is that V is more than or equal to VCOM+2 (VDL-VCOM) / 3 and smaller than or equal to VCOM+(VDL-VCOM) / 3. According to the embodiment provided by the invention, a voltage retention rate of pixels in a display driving period is improved, and the driving frequency of the display panel is reduced.
Description
Technical field [0001] The embodiments of the present invention relate to display technology, and in particular to a driving method of a display panel, a display panel and a display device. Background technique [0002] With the development of display technology, the display effect of liquid crystal display products has been continuously improved, thereby making the application of liquid crystal display products more and more widespread. [0003] The power consumption of a display product is directly proportional to the display drive frequency. In order to reduce the power consumption of the product, it is necessary to reduce the display drive frequency. However, after the current display product reduces the driving frequency, the holding voltage of the pixel is continuously reduced due to the longer driving cycle, and the voltage holding rate of the pixel in the display driving cycle decreases, and the display screen is prone to flicker, which affects the display effect.
