Abstract
Official abstract text for this publication.
A stage circuit and a scan driver using the same that is capable of concurrently (e.g., simultaneously) or progressively supplying a scan signal to a plurality of scan lines. The stage circuit includes a progressive driver and a concurrent driver.
First claim
Opening claim text (preview).
What is claimed is: 1. A stage circuit comprising: a progressive driver comprising a first transistor coupled between a first power source and an output terminal of the stage circuit, a gate electrode of the first transistor being directly coupled to a first input terminal of the stage circuit; a second transistor coupled between the output terminal and a second input terminal of the stage circuit, a gate electrode of the second transistor being coupled to a first node; a third tr…
