Publication number: 20220170974Abstract: This application discloses a flexible sensing system and an associated proximity sensing method. The flexible sensing system includes: a first thin film encapsulation layer and a first electrode layer attached to the first thin film encapsulation layer; the first electrode layer includes a bipolar electrode configured for forming an arc-shaped electric field for determining whether a distance between a target object and the sensing system is within the first distance range; the first electrode layer further includes a unipolar electrode configured for forming a vertical electric field for determining whether a distance between the target object and the sensing system is within the second distance range; and the first distance range is less than the second distance range. By using different sensing solutions for the object at different distance positions, the sensing system avoids the issue that a single sensing solution has a relatively low sensing accuracy.Type: ApplicationFiled: February 15, 2022Publication date: June 2, 2022Inventors: Yuan DAI, Peng LU, Siyuan LIU, Ke CHEN, Zhengyou ZHENG, Chuanfei GUO

Patent number: 8133642Abstract: A metal optical grayscale mask includes a layer of metal film which is deposited on transparent substrate, and different transparency pattern which is formed by laser writing on the surface of the metal film. The pattern is continuous, in type of array or random pattern. The grayscale is within 3.0 OD-0.05 OD. The thickness of the metal film is 5-100 nm. A manufacturing method of the metal optical grayscale mask includes that the selected transparent substrate is rinsed by the general semiconductor rinse process, the metal film is deposited on the transparent substrate then different transparency pattern is formed by laser writing on the surface of the metal film. The pattern is continuous, in type of array or the random pattern. The grayscale mask is low in price, antistatic electricity performance is good, the resolution can surpass optical diffraction limit. The manufacturing method is simple.Type: GrantFiled: December 3, 2010Date of Patent: March 13, 2012Assignee: National Center for Nanoscience and TechnologyInventors: Chuanfei Guo, Qian Liu, Sihai Cao, Yongsheng Wang
