Every other embodiment obtained under the premise of creative work out, shall fall within the protection scope of the present invention.
Below in conjunction with attached drawing, technical solution disclosed in each embodiment that the present invention will be described in detail.
The present invention provides a kind of terminal device, and terminal device can be mobile phone, tablet computer etc..As shown in Figure 2 and Figure 3, should
Terminal device includes shell 1 and the camera 4, light emitting source 5, light guide 6, the circuit board, display screen that are separately positioned in shell 1
11.Shell 1 is equipped with lightlng hole, obtains ambient light 2 corresponding with extraneous made thing body 8 by lightlng hole.Display screen 11 is fixed on
The front of shell 1.Light emitting source 5 is fixed on the back side (11 back side of display screen towards 1 back side of shell) of display screen 11,5 energy of light emitting source
The light 3 of directive finger 7 is enough issued, then light 3 is again under the reflection of finger 7 in directive shell 1.Light guide 6 will be arranged
Between camera 4 and light emitting source 5, ambient light 2 and light 3 are directed in camera 4.Camera 4 receives ambient light 2 or light
Generate corresponding with ambient light 2 or light 3 electric signal, and camera 4 and circuit board electrical connection after 3, camera 4 is by generation
Electric signal is sent to circuit board, and realization is taken pictures or the functions such as fingerprint application (such as fingerprint typing, unlocked by fingerprint or fingerprint decryption).
In the terminal device, ambient light 2 is not only changed into electric signal by camera 4, while will also light corresponding with fingerprint
Line 3 changes into electric signal, saves the components such as CMOS1 ' of optical fingerprint mould group in the prior art, is that the thickness of terminal device is thinning
Advantage is provided with battery volume is increased.
To achieve the above object, each component of terminal device can be arranged in many ways, below with specific embodiment
For, the construction of each component is discussed in detail.
In one embodiment, as shown in Fig. 2, Fig. 3, Fig. 5, camera 4 is rear camera 4, and lightlng hole setting exists
The front of shell 1 is arranged in the back side of shell 1, light emitting source 5.
Lightlng hole and camera 4 are located at the same end of terminal device, are specifically as follows the upper end of terminal device, lightlng hole leans on
Nearly camera 4.Camera 4 can be zoom camera 4, including VCM41 (Voice Coil Motor, voice coil motor), eyeglass
Figure and comparison or typing fingerprint feature information are adopted in 42 and CMOS43 etc., CMOS43 completion.Camera 4 is towards inside shell 1, i.e. mirror
Inner sidewall of the piece 42 towards terminal device.
The lower end of terminal device is arranged in light emitting source 5, farther out from camera 4.1 front of shell is equipped with display screen 11 and cover board
12, light emitting source 5 is folded between display screen 11 and cover board 12.Finger 7 touch or pressing light emitting source 5 after, light emitting source 5 is towards finger
7 emit beam 3, and light 3 irradiates the valley and a ridge position of finger 7, and penetrates cover board 12 and display screen 11 under the reflection of finger 7, arrive
Up to light guide 6.
Light guide 6 includes light conducting piece 61, the first reflecting element 62 and the second reflecting element 63.First reflecting element 62 is arranged in light
Between conducting piece 61 and light emitting source 5, the second reflecting element 63 is arranged between light emitting source 5 and camera 4.Light after the reflection of finger 7
Successively the directive camera 4 after the first reflecting element 62, light conducting piece 61 and the second reflecting element 63, ambient light 2 are anti-through second for line 3
It penetrates part 63 and reflexes to camera 4.
It is provided with light conducting piece 61, it is possible to reduce the loss of light 3.Light conducting piece 61 can be optical fiber or light pipe, this
Place is preferential to select optical fiber, and the logical capacity of optical fiber is big, repeater span is long, light loss is small, and the optical fiber applied to the terminal device can be with
For the fiber optic bundle that multifiber is constituted, the cross-sectional diameter of fiber optic bundle about in 0.3mm or so, occupies little space, substantially not with
Other component in terminal device interferes.
Light conducting piece 61 prolongs along the back side (in other words along display screen 11) linear extension of shell 1 from close to 5 one end of light emitting source
It extends to close to 4 one end of camera, structure is simple, facilitates setting.Further, light conducting piece 61 is closer to display screen 11, can
To be sticked at the back side of display screen 11, can also be fixed on the middle frame support of terminal device.After fixing light conducting piece 61, light
The center line of conducting piece 61 and the misalignment of camera 4.At this point, light guide 6 can also include being located at the second reflecting element 63
Third reflecting element 64 between light conducting piece 61, third reflecting element 64 can be fixed on 61 exit of light conducting piece, for one side
It is configured to the prism of fully reflecting surface, the direction of propagation of 45 degree of reflected lights of fully reflecting surface.Light 3 from light conducting piece 61 injection after,
The second reflecting element 63 is reflexed to through third reflecting element 64, to facilitate the second reflecting element 63 of setting.
Second reflecting element 63 can be arranged in many ways.In first example, as shown in Figure 3, Figure 4, the second reflecting element
