Under-screen biometric identification apparatus, biometric identification component and terminal device
Provided are an under-screen biometric identification apparatus, a biometric identification component and a terminal device. The under-screen biometric identification apparatus includes: a display screen and a biometric identification module, where the biometric identification module is fixedly disposed under the display screen, and there is a gap between the biometric identification module and the display screen. In an embodiment of the present application, the biometric identification module and a lower surface of the display screen are designed to be separated, which can reduce difficulty of disassembling the biometric identification module, thereby improving maintainability of the terminal device. Further, complexity of manufacturing the biometric identification module under the display screen can be reduced and a production success rate can be enhanced, and thus production cost is reduced.
