Abstract:
A gate driver on array (GOA) circuit, wherein each of GOA units includes a pull-up control circuit, wherein a control terminal thereof receives a first control signal, and a second terminal thereof outputs a second control signal; a pull-up circuit including a first transistor, wherein a control terminal thereof is connected to the second terminal of the pull-up control circuit, a first terminal thereof receives a first clock signal, and a second terminal thereof outputs a driving signal; a bootstrap capacitor connected between the second terminal of the pull-up control circuit and the second terminal of the first transistor; and a cascade-transmission circuit including a second transistor, wherein a control terminal thereof is connected to the second terminal of the pull-up control circuit, and a second terminal thereof outputs a cascade-transmission signal; wherein a duty cycle of the first clock signal is less than 33%.
