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...

Abstract

The invention is applicable to the technical field of terminals, and provides a mobile terminal and a flashlight fingerprint identification assembly thereof. The flashlight fingerprint identificationassembly comprises a flashlight, an optical fingerprint sensor and a data reading chip; the mobile terminal comprises a controller; the optical fingerprint sensor is arranged on the light emitting side of a flashlight; the light sensing side of the optical fingerprint sensor backs to the light emitting side of the flashlight; and the positive projection area of the optical fingerprint sensor on the flash emitting surface of the flashlight is smaller than the area of the light emitting surface of the flashlight, or the optical fingerprint sensor adopts a light-transmitting structure. The integrated arrangement of the flashlight and the optical fingerprint sensor can be realized, so that the space occupied by the optical fingerprint sensor is reduced.

Description

technical field [0001] The present application belongs to the technical field of terminals, and in particular relates to a mobile terminal and a flashlight fingerprint identification component thereof. Background technique [0002] In recent years, as users pay more and more attention to personal privacy protection and demand for various entertainment functions of mobile terminals, it has gradually become a mainstream development trend to equip terminals with camera and fingerprint recognition functions. In order to improve the camera effect in low-light environment, a flash light is usually set near the camera component of the terminal to supplement the light for the subject in the low-light environment. [0003] However, the existing fingerprint identification components are usually independently arranged under the display screen, on the side of the terminal or on the back of the terminal, occupying a lot of space. Contents of the invention [0004] In view of this, the...
