A control subunit (100), shift register units (201, 202… 20N), a shift register, a grid drive circuit and a display device. The control subunit (100) comprises a low-level input end (VGL), a gating module and N groups of nodes (Q1', QB1', Q2', QB2'… QN', QBN'), each group of nodes (Q1', QB1', Q2', QB2'…QN', QBN') comprising first control nodes (Q1', Q2'…QN') and second control nodes (QB1', QB2'…QBN'); when the first control node (Q1') in one group of nodes (Q1', QB1') is at a high level and the second control node (QB1') in the group of nodes (Q1', QB1') is at a low level, the gating module can connect the second control nodes (QB2'…QBN') in remaining N-1 groups of nodes (Q2', QB2'…QN', QBN') to the low-level input end (VGL), thereby enabling the first control nodes (Q2'…QN') and the second control nodes ((QB2'…QBN') in the remaining N-1 groups of nodes (Q2', QB2'…QN', QBN') to be at low levels, wherein N is an integer greater than 1. A narrow frame design of a display panel can be realized. |
