Embodiment 1
[0050] Such as figure 1 As shown, this embodiment provides a flashlight fingerprint recognition component 100, which is applied to a mobile terminal 200. The flashlight fingerprint recognition component 100 includes a flashlight 10, an optical fingerprint sensor 20 and a data reading chip 30, and the mobile terminal 200 includes a controller 201.
[0051] In a specific application, the mobile terminal may be any type of mobile terminal such as a mobile phone, a tablet computer, a smart bracelet, a notebook computer, a portable payment terminal, and a personal digital assistant.
[0052] Such as figure 1 As shown, in this embodiment, the optical fingerprint sensor 20 is arranged on the light-emitting side of the flashlight 10, and the photosensitive side of the optical fingerprint sensor 20 faces away from the light-emitting side of the flashlight 10; wherein, the optical fingerprint sensor 20 is on the light-emitting surface of the flashlight 10 The area of the orthographic...
Embodiment 2
[0069] Such as figure 2 As shown, in this embodiment, the flashlight 10 includes an annular array composed of several light emitting elements 11; the orthographic projection of the optical fingerprint sensor 20 on the light emitting surface of the flashlight 10 falls into the hollow area of the annular array.
[0070] In a specific application, when the optical fingerprint sensor is a non-transparent structure, the area of the orthographic projection of the optical fingerprint sensor on the light-emitting surface of the flashlight may be smaller than or equal to the area of the hollow area of the annular array.
[0071] In a specific application, the ring array can be set as a rectangular ring, a circular ring, an elliptical ring or any other polygonal ring according to actual needs.
[0072] figure 2 exemplarily shows that the orthographic area of the optical fingerprint sensor 20 on the light emitting surface of the flash lamp 10 is equal to the area of the ho...
Embodiment 3
[0080] Such as Figure 4 As shown, in this embodiment, the optical fingerprint sensor 20 includes an optical fingerprint sensing array composed of several photosensitive elements 21 and several electronic switches 22 , and each photosensitive element 21 corresponds to one electronic switch 22 .
[0081] In a specific application, the photosensitive element may specifically be a photosensitive diode or a photosensitive triode, and the electronic switch may specifically be a relay, a triode, a field effect transistor, a thin film transistor, and the like.
[0082] Such as Figure 4 As shown, in this embodiment, the connection relationship of each component of the optical fingerprint sensor 20 is as follows:
[0083] The input ends of all photosensitive elements 21 are connected together to form the reference signal input end of the optical fingerprint sensor 20, that is, the input ends of all photosensitive elements 21 are electrically connected to the reference signal output e...
