Patent number: 8264641Abstract: An optical compensated bend (OCB) mode liquid crystal display (LCD) includes a pixel electrode, a color filter, a common electrode and a liquid crystal layer. The pixel electrode is formed on the first substrate of the OCB mode LCD. The color filter is formed on the second substrate of the OCB mode LCD. The common electrode is formed on the color filter. The liquid crystal layer is sandwiched between the first substrate and the second substrate. A step structure is formed on the second structure, so that the liquid crystal molecules in the liquid crystal layer are twisted into the bend state from the splay state uniformly and quickly.Type: GrantFiled: October 15, 2008Date of Patent: September 11, 2012Assignee: AU Optronics Corp.Inventors: Chia-Yu Lee, Ting-Jui Chang, Po-Lun Chen, Jeng-Fang Wu

Patent number: 8049739Abstract: A liquid crystal display includes a light source for emitting light, a first substrate, a second substrate parallel to and facing the first substrate, and a plurality of pixel units formed between the first substrate and the second substrate. At least one pixel unit comprises a reflecting element disposed on the first substrate for reflecting light from the light source, and a photo-sensing element, formed on the second substrate, for outputting a sensing parameter based on light reflected from the reflecting member. Each reflecting element is extended out of the first substrate and faces to one of the plurality of photo-sensing elements. A position of the force applied on the first substrate is determined by detecting a variation of the sensing parameter outputted by the photo-sensing element.Type: GrantFiled: April 16, 2007Date of Patent: November 1, 2011Assignee: AU Optronics Corp.Inventors: Jeng-fang Wu, Cheng-han Tsao, Yen-ting Chen, Yi-pai Huang, Ting-jui Chang

Patent number: 7737940Abstract: A liquid crystal display includes a source driver, a gate driver, a plurality of pixel units, a plurality of detecting circuits, and a decision unit. Each pixel unit includes a switch transistor and a liquid crystal capacitor. When turned on by a scan signal generated by the gate driver, the switch transistor conducts a data signal voltage generated by the source driver to the liquid crystal capacitor, to adjust alignment of liquid crystal molecules. Each detecting circuit is electrically connected to one pixel unit, and includes a first transistor, a second transistor, a third transistor and a sensor unit. The first transistor conducts a constant voltage to the sensor unit when turned on, and generates a dynamic voltage when turned off. Based on the dynamic voltage, the second transistor generates a dynamic current. The third transistor conducts the dynamic current to the decision unit when turned on.Type: GrantFiled: August 28, 2007Date of Patent: June 15, 2010Assignee: AU Optronics Corp.Inventors: Jeng-fang Wu, Cheng-han Tsao, Chih-wei Wang, Yen-ting Chen, Kun-hua Tsai, Yi-pai Huang, Chi-mao Hung, Ting-jui Chang, Ming-sheng Lai, Min-feng Chiang, Po-yuan Liu, Chun-ting Liu
