  • Patent number: 12034705
    Abstract: System and methods are provided to facilitate the exchange of user data between two parties, but limit the exchange of user data to users that are known to both parties. According to an embodiment, encrypted first user data is transmitted from a first device to a second device. The second device then transmits intersection data to the first device, where the intersection data is based on the encrypted first user data and second user data. The intersection data may be decrypted by the first device and the first device may determine, based on the decrypted intersection data, that one or more users are common to the both the first device and the second device. The first and second devices may then exchange data pertaining to the common users.

  • Publication number: 20220208897
    Abstract: An organic light-emitting diode display screen (100) includes: a substrate (131), a buffer layer (132), a first electrode layer (133b), a pixel layer (133a), a second electrode layer (133c), a packaging layer (134), a polarizing layer (135), and a cover plate (136). The pixel layer (133a) includes a main display area (140) and a light transmissive area (139). The polarizing layer (135) has a polarizing layer through hole (135a). The part of the pixel layer (133a) located directly below the polarizing layer through hole (135a) forms the light transmissive layer (139), and the main display area (140) and the light transmissive area (139) are not separated using a packaging material. The packaging layer (134) packages the pixel layer (133a) by covering upper surfaces of the main display area (140) and the light transmissive area (139). There also provides a corresponding under-screen camera assembly and a terminal device.
