DRIVING CIRCUIT OF DISPLAY PANEL, DISPLAY DEVICE, AND METHOD FOR DRIVING THE DRIVING CIRCUIT OF THE DISPLAY PANEL

摘要

A driving circuit of a display panel includes a switching unit, a clamping unit that prevents reverse current leakage, a reference signal line coupled to a low level signal, a pull-up unit, and a pull-up control unit that drives the pull-up unit. An input end of the pull-up unit receives a second clock signal, and an output end of the pull-up unit is coupled to a current scan line, where the current scan line is coupled to a pull-down maintain unit, and the pull-down maintain unit includes a first switching unit and a second switching unit. The first switching unit and the second switching unit are connected between the current scan line and the reference signal line in parallel, where a control end of the first switching unit and a control end of the second switching unit are coupled to an output end of the switching unit, a control end of the switching unit receives a first clock signal, and an input end of the switching unit receives the second clock signal through the clamping unit.
