Patent number: 8520179Abstract: A wiring structure of a liquid crystal display (LCD) panel is provided. The wiring structure includes: a gate electrode layer, formed on a glass substrate; a first insulating layer, covering the glass substrate and partially formed on the gate electrode layer, such that at least one first opening is defined on the gate electrode layer; a source/drain electrode layer, formed on the first insulating layer, in which the source/drain electrode layer and the gate electrode layer are horizontally staggered; a second insulating layer, partially formed on the source/drain electrode layer, and defining at least one second opening on the source/drain electrode layer; and an indium tin oxide (ITO) layer, formed on the first opening, the second opening, and/or the second insulating layer. Thus, the high impedance of the ITO layer for connecting the gate electrode layer with the source/drain electrode layer is reduced.Type: GrantFiled: December 3, 2009Date of Patent: August 27, 2013Assignee: Chunghwa Picture Tubes, Ltd.Inventors: Liang-Hao Kang, Yi-Cheng Tsai

Patent number: 8441591Abstract: A pixel array substrate includes a pixel region and a circuit region adjacent to the pixel region. A plurality of display pixel units are disposed in the pixel region and a plurality of dummy pixel units are disposed in the circuit region. Each of the dummy pixel units includes a data line, a scan line, a plurality of switching elements and a plurality of pixel electrodes. The switching elements are electrically connected to the scan line and data line. The pixel electrodes are electrically connected to the switching elements. Particularly, electrostatic currents in the pixel region can be dissipated by the dummy pixel units in the circuit region. The dummy pixel units preserve the continuity of electricity in the pixel array substrate and function as an inner short ring. Therefore, the area of the circuit region on the pixel array substrate is larger.Type: GrantFiled: October 28, 2012Date of Patent: May 14, 2013Assignee: Chunghwa Picture Tubes, Ltd.Inventors: Liang-Hao Kang, Yang-Hui Chang
