Patent number: 11984538Abstract: A thin-film white LED chip includes a transparent substrate, a first transparent electrode, an emissive structure, a second transparent electrode, and a first phosphorescent/fluorescent layer respectively arranged in sequence. The emissive structure includes an emissive layer, an electron injection layer and a hole injection layer respectively formed at both sides of the emissive layer, and a total thickness of the electron injection layer and the second transparent electrode (in an inverted structure) or a total thickness of the hole injection layer and the second transparent electrode (in a conventional structure) is smaller than a length of one emission wavelength of the emissive layer. The evanescent wave generated by total internal reflection can penetrate into and be absorbed by the first phosphorescent/fluorescent layer to further emit light, thereby the overall external quantum efficiency of the LED chip is improved.Type: GrantFiled: May 26, 2021Date of Patent: May 14, 2024Assignee: SOUTH CHINA UNIVERSITY OF TECHNOLOGYInventors: Ziming Chen, Xuanli Ye, Zhenchao Li, Yong Cao

Patent number: 9881438Abstract: A method for printing stock anti-counterfeiting by using a feature image and a corresponding system is disclosed. The method comprises obtaining a feature code for identifying a printing stock by recognizing a first feature of the feature image printed on the printing stock; searching for pre-recorded first anti-counterfeiting information of the printing stock; obtaining second anti-counterfeiting information of the printing stock by recognizing a second feature of the feature image printed on the printing stock; and comparing whether a similarity between the second anti-counterfeiting information and the first anti-counterfeiting information reaches a first match threshold value to determine whether the printing stock is true or false. The first anti-counterfeiting information is embodied as a distinguishable material feature of the printing stock in a feature image region or features of color, shape and position of the image printed in the feature image region.Type: GrantFiled: October 21, 2014Date of Patent: January 30, 2018Assignee: RUSI Information Technology (Shanghai) Co., Ltd.Inventors: Lixin Zhao, Hongzhou Chen, Ziming Chen, Wei Guo

Publication number: 20150113064Abstract: Network information push is described. The described techniques include: obtaining friend information of a user according to user identity of the user, and determining whether any friends of the user have interactions with a corresponding network service; and if yes, pushing to the user information about the network service and information about the interactions occurred between the user's friends and the network service. With the method and system of the present disclosure, information about the network services and information about the interactions occurred between the user's friends and the network service are pushed initiatively to the user without the need to collect information by the user, which is more convenient and efficient. Further, since the interaction information is obtained according to the friend information of the user, it may have higher correlation with the user, and thus improve the accuracy of information push.Type: ApplicationFiled: December 23, 2014Publication date: April 23, 2015Applicant: Tencent Technology (Shenzhen) Company LimitedInventors: Ziming Chen, Yiguo Yang, Yingyi Jiang
