Does Huawei mate30pro have a screen fingerprint to unlock? Huawei mate30pro supports screen fingerprint unlocking. This technology is mature and has the advantages of high security, fast recognition speed and high recognition success rate.
In the traditional off-screen fingerprint design, when the ambient light is strong, the human eye can observe that the position of FP module is purplish red, which has obvious color difference from other positions on the display screen, which affects the beauty of the terminal. In order to solve this problem, Huawei applied for an invention patent (application number: 20 100449.438+0) called "an off-screen fingerprint identification terminal".
The above picture is a schematic structural diagram of the display screen and fingerprint module in the terminal, which mainly includes three parts: the display screen 4 1, the light blocking material layer 42 and the fingerprint module 43. Among them, the shading material layer 42 is arranged between the display screen 4 1 and the fingerprint module 43 and on the non-display surface of the display screen, and is mainly used to prevent the reflected light incident on the fingerprint module 43 from exiting through the display screen 4 1. At present, the common off-screen or on-screen fingerprint identification devices in terminals are mainly optical fingerprint module and ultrasonic fingerprint module.
