Publication number: 20100225621Abstract: A gate driving apparatus includes a first stage which outputs a first gate output signal, and a second stage which outputs a second gate output signal. The first stage includes: a transistor which includes a gate electrode, a source electrode and a drain electrode; and a dummy transistor which includes a dummy gate electrode, a dummy source electrode and a dummy drain electrode. The gate electrode receives the second gate output signal, and the dummy source electrode is connected to the source electrode or the drain electrode of the transistor and prevents static electricity from flowing to the first stage.Type: ApplicationFiled: February 22, 2010Publication date: September 9, 2010Applicant: SAMSUNG ELECTRONICS CO., LTD.Inventors: Hyung-Gi JUNG, Jeong-Young LEE, June-Woo LEE, Sok LEE

Patent number: 7595207Abstract: To improve product yield, light is scanned on a layer on a substrate through a mask. A pattern is formed on the substrate by the exposure of the layer. The direction of scanning is substantially perpendicular to a longitudinal direction of the pattern. The capacitance difference due to coupling of the pattern to be formed and a conductive layer formed through an insulation layer is reduced. Thus, failures of a display device are reduced and the product yield is increased.Type: GrantFiled: April 1, 2004Date of Patent: September 29, 2009Assignee: Samsung Electronics, Co., Ltd.Inventors: Soon-Il Ahn, Byoung-Sun Na, Jeong-Young Lee, You-Lee Song
