  • Publication number: 20150348507
    Abstract: A circuit arranged in a gate drive area on a display panel comprises control lines. Each control line is connected with multiple gate lines, and the gate lines connected with each control line are distributed at intervals on the display panel. A switch-on level can be provided sequentially to the control lines in a preset time interval when the display panel is being shut down. The circuit mitigates or otherwise eliminates a shutdown afterimage phenomenon and also avoids delivery of a relatively large instantaneous current generated at shutdown.
