  • Publication number: 20210201729
    Abstract: The present disclosure provides a display device, a driving method and a driving system thereof. The driving method includes steps of: detecting whether a polarity of a scan signal inputted from current scan line is reversed; when the polarity of the scan signal inputted from current scan line is reversed, a time period of charging the current scan line is extended.
