Patent number: 8581878Abstract: A method for mitigating pooling mura on LCD apparatus and a LCD apparatus are provided. The method is adapted for a LCD apparatus having a plurality of pixels. The LCD apparatus is for displaying frames according to a received original display data, and each of at least a part of the pixels comprises two pixel electrodes to drive a plurality of liquid crystal molecules between the two pixel electrodes. The method comprises changing a corresponding portion of the original display data so as to rotate at least a part of the liquid crystal molecules between the two pixel electrodes of the pressed pixel toward a natural angle; and maintaining another corresponding portion of the original display data. The natural angle is a finally-presented tilt angle of the liquid crystal molecules between the corresponding two pixel electrodes having substantially no potential difference therebetween.Type: GrantFiled: October 30, 2009Date of Patent: November 12, 2013Assignee: AU Optronics Corp.Inventors: Zeng-De Chen, Hong-Ji Huang, Seok-Lyul Lee, Yuet-Ping Lee, Yu-Cheng Tsai

Patent number: 8092737Abstract: Disclosed is a method of micro/nano imprinting, which applies soft mold, pre-shaping sealing film, and soft holder arrangements to the micro/nano structure imprinting process of the curved substrates. The method of the present invention can prevent the curved surface from crumbling, which may result from high gas pressuring, and can obtain uniform imprinting pressure distribution throughout the whole curved substrate. Moreover, replicating micro/nano structures onto double-sided curve, both convex and concave, surfaces can also be achieved.Type: GrantFiled: September 3, 2008Date of Patent: January 10, 2012Assignee: National Taiwan UniversityInventors: Jer-Haur Chang, Yuet-Ping Lee, Lon A. Wang, Yung-Pin Chen

Publication number: 20100225605Abstract: A LCD panel comprises a first substrate and the second substrate. The first substrate comprises a pixel, a sensor pad arranged adjacent to the pixel, a switch electrically coupled to the sensor pad, a pixel gate line electrically coupled to the pixel, a sensor gate line electrically coupled to the switch, and a readout line. The second substrate comprises a sensing device protruding form the second substrate, and a conducting layer covering on the sensing device and electrically coupled to a predetermined power. When assembling the second substrate with the first substrate, the sensing device is opposite to the sensor pad. When pressing the second substrate, the conducting layer covering on the sensing device contacts with the sensor pad. The sensor gate line controls on/off state of the switch to determine whether the sensor pad is electrically conducted with the readout line.Type: ApplicationFiled: March 3, 2010Publication date: September 9, 2010Inventors: Chao-Chen WANG, Yao-Jen Hsieh, Heng-Sheng Chou, Pang-Chiang Chia, Yuet-Ping Lee, Che-Chia Hsu
