Patent ID: 8582715

Claim:
A stage circuit comprising: a progressive driver comprising a first transistor coupled between an output terminal and a fifth input terminal of the stage circuit, a gate electrode of the first transistor being coupled to a first node, and a second transistor coupled between the output terminal and a first power source, a gate electrode of the second transistor being coupled to a second node; and a concurrent driver comprising an 11 th transistor coupled between a power source voltage and the output terminal, a gate electrode of the 11 th transistor being coupled to a third node, and a 12 th transistor coupled between the output terminal and the first power source, a gate electrode of the 12 th transistor being coupled to a third input terminal of the stage circuit, wherein, when the first transistor, the second transistor, the 11 th transistor, and the 12 th transistor are turned off, lower voltages than voltages applied to source electrodes are applied to the gate electrodes of the transistors.
