  • Patent number: 11631352
    Abstract: A display panel and a display device are provided. The display panel includes a display area and a non-display area, a first signal line and second signal lines located in the non-display area. The first signal line and the second signal lines are located on a same side of a substrate, in a different layer from the second signal lines. In a first area of the non-display area, the first signal line extends in a first direction and each second signal line extends in a second direction intersecting the first direction. An electrostatic buffer unit is disposed in the first area. Orthographic projections of the second signal lines and the electrostatic buffer unit onto a plane of the substrate at least partially overlap with an orthographic projection of the first signal line onto the plane of the substrate.

  • Patent number: 10885306
    Abstract: There are provided in embodiments of the present disclosure a living body detection method, system and a non-transitory computer-readable recording medium. The living body detection method includes: acquiring device information of a terminal used to acquire an image of an object to be detected; determining a device risk level of the terminal; determining a living body detection strategy based on the device risk level of the terminal. The above technical solution adjusts the living body detection strategy by utilizing the device information of the terminal, which guarantee a true living body to go through a pass of the detection at a smaller cost, and at the same time makes it difficult for a false and malicious living body to go through a pass of the detection, thereby greatly reducing security risk of the living body detection, enhancing the user experience, and preventing the malicious request from occupying the system resources.
