Patent number: 11120886Abstract: A gate driving circuit comprises a plurality of shift registers coupled in serial. An nth shift register includes a driving circuit, a pull-up circuit and a first auxiliary voltage regulator circuit. The driving circuit is electrically coupled to an output node and a first node. The driving circuit is configured to receive a clock signal and output a gate signal according to the clock signal. The pull-up circuit is electrically coupled to the driving circuit. The first auxiliary voltage regulator circuit is electrically coupled to the pull-up circuit and a second node. The first auxiliary voltage regulator circuit is configured to receive a control signal and the second node corresponding to a second voltage.Type: GrantFiled: November 11, 2019Date of Patent: September 14, 2021Assignee: AU OPTRONICS CORPORATIONInventors: Er-Lang Deng, Yuan-Nan Chiu, Chih-Yuan Wu, Yu-Lin Huang, I-Sheng Lin, Kuo-Ting Yang

Patent number: 9268167Abstract: A liquid crystal display (LCD) panel includes an active device array substrate, an opposite substrate, a sealant, a liquid crystal layer, a black matrix, and a plurality of rough structures. The active device array substrate has a display area and a peripheral area surrounding the display area, and the liquid crystal layer and the peripheral area are surrounded by the sealant. The black matrix is disposed between the active device array substrate and the opposite substrate and distributed corresponding to the display area and the peripheral area. The rough structures are disposed on a portion of the black matrix and distributed corresponding to the peripheral area. Surface roughness of the rough structures is greater than surface roughness of the black matrix distributed corresponding to the display area.Type: GrantFiled: November 15, 2013Date of Patent: February 23, 2016Assignee: Au Optronics CorporationInventors: Wen-Hsien Tseng, Yen-Heng Huang, Chia-Hui Pai, Chung-Kai Chen, Wei-Yuan Cheng, Yi-Jen Huang, Chun-Jen Chiu, Yu-Zhi Wu, Yuan-Nan Chiu

Patent number: 8319933Abstract: A liquid crystal display panel has a display region and a peripheral region defined thereon. The peripheral region is disposed at an outside of the display region, and the peripheral region includes a bridge circuit region. The liquid crystal display panel includes a first substrate, a first conductive layer, a second substrate, a second conductive layer and a spacer. The first conductive layer is disposed on the first substrate in the bridge circuit region. The second substrate is disposed in parallel to a side of the first substrate, and the second conductive layer is disposed on the second substrate in the peripheral region. The spacer is disposed between the first conductive layer and the second conductive layer in the bridge circuit region, and the spacer electrically isolates the first conductive layer from the second conductive layer.Type: GrantFiled: November 3, 2010Date of Patent: November 27, 2012Assignee: AU Optronics Corp.Inventors: Wen-Tsan Chiou, Yuan-Nan Chiu, Chao-Wei Huang

Publication number: 20120033114Abstract: An active device array substrate including a substrate, multiple scan lines, multiple data lines, multiple of pixels are provided. The scan lines and the data lines are disposed on the substrate. Each pixel includes multiple sub-pixels including at least a transistor, a pixel electrode, and a color filter. The transistor is disposed on the substrate and electrically connected to the scan line and the data line correspondingly. A portion of the color filter is disposed between the pixel electrode and the corresponding scan line. The pixel electrode is coupled with the corresponding scan line to form a first capacitor. The drain of the transistor is coupled with the corresponding scan line to form a second capacitor. In a single pixel, the coupling areas of the pixel electrodes corresponding to various color filters with the corresponding scan lines are different, so that capacitance of the first capacitors are substantially the same.Type: ApplicationFiled: November 30, 2010Publication date: February 9, 2012Applicant: AU OPTRONICS CORPORATIONInventors: Min-Hsiang Hung, Ming-Yung Huang, Chun-Jen Chiu, Yu-Zhi Wu, Yuan-Nan Chiu, Chin-An Tseng, Yen-Heng Huang
