Patent ID: 8320516

Claim:
A pulse signal output circuit comprising: a first transistor and a second transistor, a first terminal of the first transistor and a first terminal of the second transistor being electrically connected to a first output terminal; a third transistor and a fourth transistor, a first terminal of the third transistor and a first terminal of the fourth transistor being electrically connected to a second output terminal; a fifth transistor; and a sixth transistor, wherein a first terminal of the fifth transistor, a gate of the first transistor and a gate of the third transistor are electrically connected to each other; wherein a gate of the fifth transistor, a first terminal of the sixth transistor, a gate of the second transistor and a gate of the fourth transistor are electrically connected to each other; and wherein a channel of the fifth transistor and a channel of the sixth transistor are each longer than a channel of the third transistor and a channel of the fourth transistor.
