Publication number: 20240124163Abstract: A magnetic multi-pole propulsion array system is applied to at least one external cathode and includes a plurality of magnetic multi-pole thrusters connected adjacent to each other. Each magnetic multi-pole thruster includes a propellant provider, a discharge chamber, an anode and a plurality of magnetic components. The propellant provider outputs propellant. The discharge chamber is connected with the propellant provider to accommodate the propellant. The anode is disposed inside the discharge chamber to generate an electric field. The plurality of magnetic components is respectively disposed on several sides of the discharge chamber. One of the several sides of the discharge chamber of the magnetic multi-pole thruster is applied for one side of a discharge chamber of another magnetic multi-pole thruster.Type: ApplicationFiled: December 19, 2022Publication date: April 18, 2024Applicant: National Cheng Kung UniversityInventors: Yueh-Heng Li, Yu-Ting Wu, Chao-Wei Huang, Wei-Cheng Lo, Hsun-Chen Hsieh, Ping-Han Huang, Yi-Long Huang, Sheng-Wen Liu, Wei-Cheng Lien

Patent number: 11916012Abstract: A manufacturing method of a semiconductor structure is provided. A first semiconductor die includes a first semiconductor substrate, a first interconnect structure formed thereon, a first bonding conductor formed thereon, and a conductive via extending from the first interconnect structure toward a back surface of the first semiconductor substrate. The first semiconductor substrate is thinned to accessibly expose the conductive via to form a through semiconductor via (TSV). A second semiconductor die is bonded to the first semiconductor die. The second semiconductor die includes a second semiconductor substrate including an active surface facing the back surface of the first semiconductor substrate, a second interconnect structure between the second and the first semiconductor substrates, and a second bonding conductor between the second interconnect structure and the first semiconductor substrate and bonded to the TSV.Type: GrantFiled: June 29, 2021Date of Patent: February 27, 2024Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Ming-Fa Chen, Sung-Feng Yeh, Tzuan-Horng Liu, Chao-Wen Shih

Patent number: 8704848Abstract: A transform model is established by the calibration system for color transformation between a first color space and a second color space. Three first target curves are defined and transformed by the transform model so as to establish three look-up tables. The display is calibrated according to the three look-up tables such that the color temperature of the display may be substantially constant for every gray-level.Type: GrantFiled: June 10, 2009Date of Patent: April 22, 2014Assignee: Young Lighting Technology Inc.Inventors: Chao-Wen Liu, Hung-Wei Chih

Patent number: 7894197Abstract: An optical sensing module is adapted to be assembled to a frame of a display device. The display device comprises a display module and the frame, and the display module has a display area and the frame surrounds the display area. The optical sensing module comprises a casing and an optical sensor. The casing is pivoted to the frame and the optical sensor is configured in the casing for sensing external light projecting on a side of the casing. The optical sensor is capable of sensing a brightness of the display area when the side of the casing faces the display area and sensing a brightness of an ambient light when the side of the casing doesn't face the display area.Type: GrantFiled: December 4, 2007Date of Patent: February 22, 2011Assignee: Coretronic CorporationInventors: Wei-Cheng Hwang, Chao-Wen Liu, Yung-Lung Liu, Chwen-Tay Hwang

Publication number: 20090033646Abstract: A display includes a display module, a light source, a light source driving circuit, a display driving circuit, and an optical sensor. The optical sensor is installed next to the light source for detecting the luminance and color temperature of the light source. The optical sensor is coupled to the display driving circuit for generating a feedback signal to the display driving circuit according to the luminance and the color temperature of the light source. The display driving circuit drives the display module to display an image according to a received image signal and updates the data of the image signal according to the feedback signal so as to adjust the luminance and the color temperature of the image.Type: ApplicationFiled: April 21, 2008Publication date: February 5, 2009Inventors: Chao-Wen Liu, Chih-Kuo Lee
