Embodiment 1

[0051] Such as image 3 As shown, Embodiment 1 of the present invention proposes a light sensor assembly 300 , the light sensor assembly 300 includes an optical glass lens 310 , a reflector 320 , a focusing lens 330 , an image sensor 340 , a receiving groove 350 and a built-in light source 360 ​​.

[0052] In this example, if image 3 As shown, the accommodating tank 350 is surrounded by the isolation and noise-eliminating walls 351 , and may specifically be a rectangular tank or a circular tank. The built-in light source 360 ​​is built in the isolation and noise-reduction wall 351 , which can prevent the light emitted from the built-in light source 360 ​​from directly entering the receiving groove 350 . The optical glass lens 310 covers an opening side of the receiving groove 350 , and the emitted light of the built-in light source 360 ​​is directed toward the optical glass lens 310 . Specifically, the edge of the optical glass lens 310 is embedded in the isolation and nois...

Embodiment 2

[0060] Such as Figure 6 As shown, Embodiment 2 of the present invention proposes a light sensor assembly control method, which is applied to the light sensor assembly 300 of Embodiment 1 of the present invention. The light sensor assembly control method includes the following steps:

[0061] Step S1: When the image sensor receives the light focused by the focusing lens with consistent brightness and darkness, the light sensor component switches the light sensing working mode, and the image sensor converts the external light signal of the consistent brightness and darkness focused by the focusing lens into a switch control electrical signal.

[0062] Specifically, such as Figure 4 As shown, when the optical glass lens 310 of the light sensor assembly 300 is not blocked by foreign objects such as fingers, it can normally receive external light, and the received external light is consistent in brightness and darkness, that is, the optical glass lens 310 receives light at the sa...

Embodiment 3

[0066] Such as Figure 7 As shown, the third embodiment of the present invention proposes a mobile terminal 400, the mobile terminal 400 includes the light sensor assembly 300 in the first embodiment, the light sensor assembly 300 includes an optical glass lens 310, a reflector 320, and a focusing lens 330 And the image sensor 340 , the receiving groove 350 and the built-in light source 360 ​​.

[0067] In this example, if image 3 As shown, the accommodating tank 350 is surrounded by the isolation and noise-eliminating walls 351 , and may specifically be a rectangular tank or a circular tank. The built-in light source 360 ​​is built in the isolation and noise-reduction wall 351 , which can prevent the light emitted from the built-in light source 360 ​​from directly entering the receiving groove 350 . The optical glass lens 310 covers an opening side of the receiving groove 350 , and the emitted light of the built-in light source 360 ​​is directed toward the optical glass le...

Abstract

The invention discloses a light sensor assembly, a control method thereof and a mobile terminal, and belongs to the technical field of terminal equipment sensor fittings. The light sensor assembly comprises an optical glass lens used for receiving external light rays and refracting the light rays to a reflector, or receiving the reflected light rays of a built-in light source and refracting the light rays to the reflector; the reflector used for receiving the external light rays or the light rays of the built-in light source refracted by the optical glass lens and reflecting the light rays toa focusing lens; the focusing lens used for focusing the external light rays or the light rays of the built-in light source reflected by the reflector into an image sensor; and the image sensor used for converting the signals of external light rays, which are focused by the focusing lens and are consistent in brightness and darkness, into switch control electric signals, or collecting the light rays of the built-in light source, which are focused by the focusing lens and are inconsistent in brightness and darkness, into a fingerprint image. The light sensor assembly has the light sensing function and the fingerprint collecting function at the same time.

Description

technical field [0001] The present invention relates to the technical field of terminal equipment sensor accessories, in particular to a light sensor component and a mobile terminal with the light sensor component. Background technique [0002] With the advancement of technology, the functions on mobile terminals are becoming more and more powerful. Most of these functions rely on various sensors set on mobile terminals, such as gyroscopes, distance sensors, light sensors, and fingerprint sensors. etc. Among them, the light sensor is to change the brightness of the screen according to the change of ambient light. It has two basic functions, one is to achieve the purpose of saving electricity through intelligent adjustment, which is more environmentally friendly. The second is to bring users the best visual effects. The fingerprint sensor is a way to verify the real identity of the user by comparing the specific feature points of the collected fingerprint image with the pr...
