Publication number: 20250067954Abstract: An optical member driving mechanism is provided. The optical member driving mechanism includes a first movable portion used for connecting an optical element, a fixed portion, a first driving assembly used for driving the first movable portion to rotate relative to the fixed portion, and a guiding assembly having a first intermediate element. The first movable portion is movable relative to the fixed portion. The guiding assembly is used for applying a first stabilized force to the first movable portion for making the first intermediate element be in contact with the first movable portion or the fixed portion. The first movable portion is rotatable relative to the fixed portion.Type: ApplicationFiled: November 8, 2024Publication date: February 27, 2025Inventors: Chih-Wei WENG, Chao-Chang HU, Yueh-Lin LEE, Chen-Hsien FAN, Chien-Yu KAO, Chia-Ching HSU, Sung-Mao TSAI, Sin-Jhong SONG

Patent number: 12235409Abstract: An optical lens assembly includes, from an object side to an image side, at least four optical lens elements. At least one of the at least four optical lens elements includes an anti-reflective coating. The at least one optical lens element including the anti-reflective coating is made of a plastic material. The anti-reflective coating is arranged on an object-side surface or an image-side surface of the at least one optical lens element including the anti-reflective coating. The anti-reflective coating includes at least one coating layer. One of the at least one coating layer at the outer of the anti-reflective coating is made of ceramics. The anti-reflective coating includes a plurality of holes, and sizes of the plurality of holes adjacent to the outer of the anti-reflective coating are larger than sizes of the plurality of holes adjacent to the inner of the anti-reflective coating.Type: GrantFiled: December 17, 2021Date of Patent: February 25, 2025Assignee: LARGAN PRECISION CO., LTD.Inventors: Wen-Yu Tsai, Chien-Pang Chang, Chi-Wei Chi, Wei-Fong Hong, Chun-Hung Teng, Kuo-Chiang Chu

Patent number: 12204163Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.Type: GrantFiled: February 5, 2024Date of Patent: January 21, 2025Assignee: TDK TAIWAN CORP.Inventors: Chao-Chang Hu, Chih-Wei Weng, Chia-Che Wu, Chien-Yu Kao, Hsiao-Hsin Hu, He-Ling Chang, Chao-Hsi Wang, Chen-Hsien Fan, Che-Wei Chang, Mao-Gen Jian, Sung-Mao Tsai, Wei-Jhe Shen, Yung-Ping Yang, Sin-Hong Lin, Tzu-Yu Chang, Sin-Jhong Song, Shang-Yu Hsu, Meng-Ting Lin, Shih-Wei Hung, Yu-Huai Liao, Mao-Kuo Hsu, Hsueh-Ju Lu, Ching-Chieh Huang, Chih-Wen Chiang, Yu-Chiao Lo, Ying-Jen Wang, Shu-Shan Chen, Che-Hsiang Chiu
