Abstract

The invention discloses a scanning drive circuit and a display panel. The scanning drive circuit comprises a first-side drive circuit, wherein the first-side drive circuit comprises a first drive circuit group and a second drive circuit group; the first drive circuit group comprises a plurality of first shift register units which are cascaded with one another, and each first shift register unit comprises a first scanning signal input end, a first scanning signal output end and a control node; the second drive circuit group comprises a plurality of second shift register units, and each second shift register unit comprises a second scanning signal input end and a second scanning signal output end; the first shift register units are in cascaded connection in the first drive circuit group; thesecond scanning signal input end of the xth second shift register unit in the second drive circuit group is connected to the control node of the (x+1)-stage first shift register unit. Area of a border occupied by the scanning drive circuit can be reduced.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a scan driving circuit and a display panel. Background technique [0002] With the development of display technology, the structure and shape of the display panel are also diversified. The current display panel is transitioning from the early low screen-to-body ratio to the high screen-to-body ratio. In order to increase the screen-to-body ratio of the display panel, existing technologies The display panels are all trying to reduce the frame area as much as possible. Wherein, a scanning driving circuit is usually provided in the frame area to provide scanning driving signals to the scanning lines of the display panel to realize image display. At present, the scan driving circuit of the display panel is usually implemented by cascading shift register units with the same circuit structure. Therefore, the scan driving circuit structure in the prior art has become ...
