Publication number: 20240069299Abstract: An optical element driving mechanism includes a movable assembly, a fixed assembly, and a driving assembly. The movable assembly is configured to be connected to an optical element. The movable assembly is movable relative to the fixed assembly. The driving assembly is configured to drive the movable assembly to move relative to the fixed assembly in a range of motion. The optical element driving mechanism further includes a positioning assembly configured to position the movable assembly at a predetermined position relative to the fixed assembly when the driving assembly is not operating.Type: ApplicationFiled: November 9, 2023Publication date: February 29, 2024Inventors: Chao-Chang HU, Kuen-Wang TSAI, Liang-Ting HO, Chao-Hsi WANG, Chih-Wei WENG, He-Ling CHANG, Che-Wei CHANG, Sheng-Zong CHEN, Ko-Lun CHAO, Min-Hsiu TSAI, Shu-Shan CHEN, Jungsuck RYOO, Mao-Kuo HSU, Guan-Yu SU

Patent number: 11132941Abstract: A display panel and a pixel circuit of the display panel are provided. The pixel circuit includes a driving transistor and a light-emitting time length modulator. The driving transistor has a control terminal receiving a pulse width control signal and an amplitude control signal, and the driving transistor generates a driving signal. In a first time period, the light-emitting time length modulator modulates a time length of a plurality of second time periods for providing the driving signal to a light-emitting device according to a light-emitting time control signal.Type: GrantFiled: September 10, 2020Date of Patent: September 28, 2021Assignee: Au Optronics CorporationInventors: Peng-Bo Xi, Chen-Chi Lin, Yan-Ru Chen, Cheng-Nan Yeh, Sheng-Yu Hsu, Chia-Che Hung, En-Chih Liu

Patent number: 9812083Abstract: A display device includes a substrate, display units, and a plurality of integrated circuits (ICs). The substrate includes an active area and a non-active area. The non-active area is located around the active area. The display units are disposed in the active area of the substrate, and arranged in a matrix. The ICs are disposed in the active area of the substrate, arranged in a matrix, and are electrically coupled to the display units. Each of the ICs includes a shift register unit. Each of the shift register units of the ICs is configured to receive a previous-stage scan signal, and generate a current-stage scan signal according to the previous-stage scan signal. The ICs drive the display units according to the current-stage scan signals.Type: GrantFiled: October 15, 2014Date of Patent: November 7, 2017Assignee: AU OPTRONICS CORPORATIONInventors: Shao-Wen Yen, Tsung-Shiun Lee, Yi-Cheng Liu, Sheng-Yu Hsu

Patent number: 7904874Abstract: We propose an opposite-phase scheme for peak current reduction. The basic idea is to divide the clock buffers at each level of the clock tree into two sets: one half of the clock buffers operate at the same phase as the clock source, and the other half of the clock buffers operate at the opposite phase to the clock source. Consequently, our approach can effectively reduce the peak current of the clock tree. The method enables the opposite-phase scheme to combine with the electronic design automation (EDA) tools that are commonly used in modern industries.Type: GrantFiled: January 22, 2008Date of Patent: March 8, 2011Assignee: Industrial Technology Research InstituteInventors: Yow-Tyng Nieh, Sheng-Yu Hsu, Shih-Hsu Huang, Yeong-Jar Chang
