Abstract
The present application provides a single-type GOA circuit comprising a controllable signal setting unit for providing a controllable signal. The controllable signal is held at a potential of a constant low-level voltage source when the circuit is operated in normal status, and at a potential of a constant high-level voltage source when the circuit is in a transmission suspended period. The potential of the signals in the current leakage path in the transmission suspended period is changed in the application so that voltage controlling and leakage path eliminating could be achieved and stability of the circuit is increased.
