Publication number: 20240127623Abstract: The present application discloses a display panel and a display device. The display panel includes a fingerprint recognition area. The display panel includes a cover plate and an optically transparent layer. The optically transparent layer at least covers a portion of the cover plate located in the fingerprint recognition area. A refractive index of the optically transparent layer is greater than a refractive index of air and less than a refractive index of a finger. A thickness of the optically transparent layer is an even multiple of a half-wavelength of a fingerprint recognition light ray. Half-wave loss and interference of light are used to improve fingerprint recognition performance.Type: ApplicationFiled: May 18, 2021Publication date: April 18, 2024Inventors: Chuan SHUAI, Guiyang ZHANG, Yaqiong LONG

Patent number: 11385359Abstract: The present invention provides a point cloud data acquisition method and device under a situation of no GNSS signal. The method comprises: re-sampling line data acquired from a topographic map to obtain discrete line data; generating a full-second PPS pulse in a simulating manner; counting by using a distance measuring instrument, sampling the count, when it is detected that the full-second PPS pulse is received, calculating position information at a current moment; simulating a GNSS satellite protocol according to the position information at the current moment; parsing the GNSS satellite protocol by using a point cloud data acquisition module to complete time synchronization, and controlling a LiDAR to acquire point cloud data; parsing the GNSS satellite protocol by using an inertial measurement module, and recording attitude determination positioning data in real time to generate POS data; and optimizing the POS data to obtain accurate point cloud data.Type: GrantFiled: December 25, 2017Date of Patent: July 12, 2022Assignees: CHONGQING SURVEY INSTITUTE, CHONGQING CYBERCITY SCI-TECH CO., LTD.Inventors: Hanxin Chen, Zejun Xiang, Chuan Long, Jing Ming, Yonggang Gou, Nan Lv, Han Chen, Zaiqian Luo, Feng Li, Zhi Huang, Xiaolin Hu

Patent number: 11325177Abstract: A die adjustment mechanism, includes a base, the base is provided with a die that can apply pressure on the workpiece. The die includes multiple modules arranged sequentially and capable of sliding laterally relative to the base. The base is further provided with a slide rest/slide rests capable of sliding laterally relative to the base. Each slide rest is provided with a shifting fork which can be clamped with a module or can be clamped between two adjacent modules. Each slide rest is provided with a drive component capable of driving the shifting fork to be clamped with the module or be clamped between the two adjacent modules. Using this mechanism, bending and pressing of multiple sides of the metal plate can be completed by the same machine and the production efficiency is greatly improved.Type: GrantFiled: November 30, 2017Date of Patent: May 10, 2022Assignee: OMS MACHINERY CO., LTD.Inventors: Xiaobin Long, Haifeng Hu, Chuan Long, Yang Shi
