Abstract
The present application discloses a shift register and units thereof, wherein low voltage level maintaining module () includes: a first maintaining unit () and a second maintaining unit (), configured to maintain a signal output terminal and/or the controlling terminal (Q) of the driving module () at low voltage level when an effective level is received. A threshold voltage sensing module () is coupled between the first maintaining unit () and the second maintaining unit (), the threshold voltage sensing module () is configured to control its signal output terminal to provide an effective level to the second maintain-enabling terminal (P) according to threshold voltage shift of the first maintaining unit () sensed. Therefore, low voltage maintaining module () may endure a greater threshold voltage shift, and the life span of the circuit is extended. The present application further discloses a display device and a voltage regulating circuit.
