Patent number: 7667245Abstract: A driving circuit of a liquid crystal display panel includes a substrate, a plurality of driver IC chips located on the substrate, a current supplier, and a first conductive wire set. The first conductive wire set has a plurality of conductive wire segments for connecting the driver IC chips in parallel to the current supplier. Furthermore, the conductive wire segments each have a form, such that paths formed of the conductive wire segments from the current supplier to the respective driver IC chips have an equal resistance, and, accordingly, each of the driver IC chips obtain the same input voltage. Hence, a problem of band mura is avoided.Type: GrantFiled: December 11, 2008Date of Patent: February 23, 2010Assignee: Chungwa Picture Tubes, Ltd.Inventors: Ming-Zen Wu, Chien-Chih Jen

Patent number: 7411213Abstract: A pixel structure, suitable being driven by a scan line and a data line on a substrate, is provided. The pixel structure includes a thin film transistor (TFT) and a pixel electrode. Wherein, the TFT includes a gate, a first and a second dielectric layer, a semiconductor layer, a source, and a drain. Especially, the semiconductor layer has a body part and at least one extending part connected to thereof. The extending part is protruded from the edge of the body part disposed between the source and the drain. In addition, at least one contact hole is disposed in the second dielectric layer for exposing the extending part, and the first dielectric layer, the semiconductor layer, and the second dielectric layer at the extending part are removed through the contact hole. So, leakage current can be effectively reduced, thereby raising the Ion/Ioff ratio of the pixel structure.Type: GrantFiled: April 3, 2006Date of Patent: August 12, 2008Assignee: Chunghwa Picture Tubes, Ltd.Inventors: Chien-Chih Jen, Ming-Zen Wu
