Patent number: 8503601Abstract: A gate-on array shift register includes a signal-input unit, a control transistor and at least three stable modules. The signal-input unit receives and outputs a previous-stage output signal. The control terminal of the control transistor is electrically coupled to the signal-input unit for receiving the previous-stage output signal. The control transistor outputs corresponding output signal on output terminal of the shift register according to the previous-stage output signal. Each of the stable modules is electrically coupled to the control terminal of the control transistor and the output terminal of the shift register to stabilize voltage of the terminals.Type: GrantFiled: September 23, 2011Date of Patent: August 6, 2013Assignee: AU Optronics Corp.Inventors: Po-Kai Wang, Chun-Hao Huang, Chung-Hung Peng

Patent number: 7880856Abstract: A pixel unit including a pixel electrode, a scan electrode, a common voltage electrode, a data electrode and at least one redundancy electrode is provided. During the fabricating process of the pixel unit, if a particle is simultaneously located between any two of the pixel electrode, the scan electrode and the common voltage electrode, it would cause a short circuit between the two electrodes. The pixel unit can generate a cross-shaped defect signal at the location where a short circuit happens when the pixel unit undergoes an array test or a cell test. The user can thereby quickly locate the defect and repair it.Type: GrantFiled: April 16, 2007Date of Patent: February 1, 2011Assignee: Au Optronics CorporationInventors: Chung-Hung Peng, Meng-ying Hsieh, Chi-Hung Lu, Chin-Fon Chen
