Abstract

The invention discloses a shift register circuit, a display panel and a display device. The shift register circuit comprises a plurality of cascaded shift register unit groups; each shift register unit group comprises at least two shift register units; in each shift register unit group, the signal output end of each shift register unit in the previous shift register unit group is electrically connected with the scanning control end of each shift register unit in the next shift register unit group; in the same shift register unit group, the pull-down control module of one shift register unit is multiplexed as the pull-down control modules of the other shift register units, and the signal output end of each shift register unit outputs the enable level of the scanning signal in sequence. According to the embodiment of the invention, the size of the shift register circuit can be reduced, and when the shift register circuit is applied to the display panel, a narrow frame of the display panel is facilitated.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular to a shift register circuit, a display panel and a display device. Background technique [0002] Currently, a gate driving circuit is provided in the non-display area of ​​the display panel, and the gate driving circuit can perform row-by-row scanning of the display units in the display area of ​​the display panel. However, the gate driving circuit in the prior art has a complex structure and a large size, which is not conducive to the narrow frame of the display panel. Contents of the invention [0003] The present invention provides a shift register circuit, a display panel and a display device, so as to reduce the size of the shift register circuit, thereby benefiting the narrow frame of the display panel and increasing the screen ratio of the display panel. [0004] In a first aspect, an embodiment of the present invention provides a shift register circuit, in...
