Therefore, the mobile terminal that this application provided need not to set up image module decoration, and its screen that corresponds accounts for than can have great promotion space.
The following describes in detail a specific implementation of the mobile terminal provided in the embodiments of the present application with reference to the drawings. The embodiment of the application takes a smart phone as an example of a mobile terminal to describe a specific implementation manner of the application. It should be understood that the mobile terminal according to the embodiment of the present application is not limited to a smart phone, and may also be a tablet computer or other portable electronic devices.
Example one
Please refer to fig. 1-2. Fig. 1 is a top view of a smart phone according to an embodiment of the present application, and fig. 2 is a schematic cross-sectional view of a mobile terminal according to an embodiment of the present application, taken along a cutting line i-i in fig. 1.
As shown in fig. 1 and 2, the smart phone includes:
the touch screen comprises a touch display screen 11 and a screen cover plate 12 positioned on the periphery of the touch display screen 11, wherein a camera window 13 is arranged on a preset area of the screen cover plate 12; an imaging device 21 is provided below the camera window 13.
In this embodiment of the application, the screen cover 12 of the smart phone may be a glass cover, and the preset area where the camera window 13 is located may be the top or the lower part of the screen cover 12, or may be another area of the screen cover 12. In this embodiment, the screen cover 12 can cover the area where the image device 21 is located.
The following describes a structure of the imaging device 21 of the mobile terminal according to the embodiment of the present application with reference to fig. 2.
As shown in fig. 2, the imaging device 21 provided in the embodiment of the present application may specifically include:
a camera 211 including an image module;
a camera windowing hidden part 212 located above the camera 211;
the fingerprint identification module 213 is arranged in the peripheral area of the camera 211, is positioned below the camera 211, can be a fingerprint identification sensor, and can provide a fingerprint identification function;
the touch panel 214 is disposed above the camera windowing hidden component 212, and is configured to respond to an external touch operation and start a fingerprint identification function of the fingerprint identification module 213 according to the external touch operation.
In the camera 211 of the imaging device 21, the imaging module can be triggered to start according to the start of the image capturing related function of the application program in the mobile terminal. The camera windowing hidden part 212 has different purposes in two scenes that the image module is triggered to be opened and is not triggered to be opened:
when the image module is triggered to be opened, the camera windowing hidden component 212 above the camera 211 is used for enabling external light to pass through the camera 211, and enabling the light condition to reach the light passing condition for the camera 211 to shoot. When the image module is not triggered to be opened, the camera window hiding component 212 is used for blocking external light from entering the camera 211. In the second case, when the front of the mobile terminal is viewed from above in the viewing direction shown in fig. 1, the camera window 13 area of the mobile terminal is similar to the other areas of the screen cover 12, and the camera window 13 is hardly visible from the outside, so that the appearance of the mobile terminal is more integral and beautiful, as shown in fig. 3. Fig. 3 is a top view of the smart phone provided in the embodiment of the present application when the image module is not opened.
Because the setting and the existence of part 212 are hidden in the camera windowing, under two kinds of scenes that need trigger to open the image module and need not trigger to open the image module, have different printing opacity effect and usage to external light, therefore need not to set up fixed image module decoration in mobile terminal and keep the possibility that external light incides for a long time, and then, can not occupy the planar region of screen, are favorable to improving mobile terminal's screen to account for than.
The liquid crystal cell (also called liquid crystal display panel or liquid crystal display) prepared from the liquid crystal material can meet the requirements of the camera windowing hidden component 212. As such, as an embodiment of the present application, the camera fenestration concealment component 212 may be embodied as a liquid crystal cell.
The following describes in detail a specific implementation and an operation principle of the camera windowing hidden component 212 provided in the embodiment of the present application with reference to fig. 4 and 5.
As shown in fig. 4, the camera window hiding member 212 provided in the embodiment of the present application is a liquid crystal cell. When the image module is triggered to be started, the liquid crystal box is applied with an electric field, and the arrangement direction of the long axes of the liquid crystal molecules in the liquid crystal box can be changed by the existence of the electric field, so that the light transmittance of the liquid crystal box is influenced. Based on this characteristic of the liquid crystal molecules, a function of hiding the camera opening can be realized.
Fig. 4 is a schematic cross-sectional view of a camera windowing hidden component 212 according to an embodiment of the present application. In an embodiment of the present application, a liquid crystal cell may include:
a first transparent substrate 2121 and a second transparent substrate 2122 which are oppositely arranged, wherein a liquid crystal 2123 is arranged between the first transparent substrate 2121 and the second transparent substrate 2122;
a first transparent electrode 2124 and a first alignment layer 2125 are provided in this order on a surface of the first transparent substrate 2121 adjacent to the liquid crystal 2123; a first polarizing plate 2126 is provided on a surface of the first transparent substrate 2121 facing away from the liquid crystal 2123;
a second transparent electrode 2127 and a second alignment layer 2128 are provided in this order on a surface of the second transparent substrate 2122 adjacent to the liquid crystal 2123; a second polarizing plate 2129 is provided on a surface of the second transparent substrate 2122 facing away from the liquid crystal 2123;
the liquid crystal 2123 is encapsulated in the first alignment layer 2125, the second alignment layer 2128, and the rubber frame 21210;
the first polarizing plate 2126 and the second polarizing plate 2129 have the same polarization direction, and the first alignment layer 2125 and the second alignment layer 2128 have the same alignment direction.
For the direction setting of the polarizer and the orientation layer in the structure of the camera windowing hidden component 212, the embodiment of the present application provides two specific implementation manners.
In an alternative implementation, the first polarizer 2126 and the first alignment layer 2125 are aligned, and the second polarizer 2129 and the second alignment layer 2128 are aligned perpendicular to each other.
The arrangement of the first polarizer 2126 of the camera windowing hidden component 212 close to the direction of the external light determines the polarization direction of the polarized light incident on the first transparent substrate 2121; the camera windowing hidden component 212 determines the polarization direction of the emergent polarized light by the arrangement of the second polarizer 2129 in the external light direction. The following describes the operation principle of the camera window hiding member 212 provided in the embodiment of the present application with reference to fig. 5, with a direction in which the first polarizing plate 2126 and the first alignment layer 2125 are aligned and a direction in which the second polarizing plate 2129 and the second alignment layer 2128 are perpendicular to each other as an example.
Referring to fig. 5, a schematic optical path diagram of the camera windowing hidden component 212 according to the embodiment of the present application is provided. In fig. 5, the left side is a schematic light path diagram of the camera windowing hidden component 212 when the image module is not triggered to be opened; the right side of fig. 5 is a schematic light path diagram of the camera windowing hidden component 212 when the image module is triggered to be opened.
When the camera window hiding member 212 is turned on, a voltage difference is generated between the first transparent electrode 2124 and the second transparent electrode 2127, and light passing through the first polarizing plate 2126 passes through the first alignment layer 2125, the liquid crystal 2123, and the second alignment layer 2128, and then the direction of polarized light is not changed and is aligned with the direction of the second polarizing plate 2129, so that the light can pass through the camera window hiding member 212.
When the camera window hiding member 212 is closed, there is no voltage between the first transparent electrode 2124 and the second transparent electrode 2127, and the light passing through the first polarizer 2126 passes through the first alignment layer 2125, the liquid crystal 2123 and the second alignment layer 2128, and the direction of the polarized light changes, and the changed direction is perpendicular to the direction of the second polarizer 2129, so that the light cannot pass through the camera window hiding member 212.
In the above, a specific implementation manner and an operation principle of the camera windowing hidden component 212 provided in the embodiment of the present application are provided.
Furthermore, in this application embodiment, fingerprint identification module 213 is integrated in the image device that this application embodiment provided, and, set up fingerprint identification module 213 in camera 211 peripheral region, so, fingerprint identification module 213 and camera 211 are range upon range of setting in along mobile terminal thickness direction, therefore, there is certain overlap in fingerprint identification module 213 and camera 211 occupy mobile terminal's planar region, therefore the design mode of integrating fingerprint identification module 213 in image device is favorable to sparingly the mobile terminal planar region area who occupies, prepare the antenna with more spaces left, consequently, should be favorable to providing more spaces with fingerprint identification module 213 and camera integrated image device who lies in it and prepare the antenna, the degree of difficulty of antenna design has been reduced.
It should be understood that the imaging device provided in the embodiment of the present application is not limited to the above structure in which the fingerprint identification module and the camera are integrated, and may also be a structure that does not include the fingerprint identification module.
In addition, in order to set the activation condition of the fingerprint identification module 213, the image device 21 provided in the embodiment of the present application may further include a touch panel 214 located above the camera windowing hidden component 212. The touch panel 214 can be used for responding to external touch operations, such as pressing, clicking, dragging, sliding, and other gestures. In this embodiment, the touch panel 214 can specifically start the fingerprint recognition function of the fingerprint recognition module 213 according to the external touch operation.
If the touch panel 214 receives an external touch operation and is activated, the camera windowing hidden component 212 is turned on, and the fingerprint identification module 213 starts to identify a fingerprint; if the touch panel 214 does not receive an external touch operation, or if the touch panel 214 is not activated by an error operation or an operation method although the touch panel 214 receives the external touch operation, the camera windowing hidden component 212 cannot be opened, and therefore the fingerprint identification module 213 does not need to execute the fingerprint identification function.
Because in the mobile terminal image device 21 that this embodiment provided, have fingerprint identification module 213 and touch panel 214, fingerprint identification module 213 and touch panel 214 combine together with camera windowing hidden part 212, the realization integration that shoots relevant function with the image with the fingerprint identification function of mobile terminal is in the relatively intensive planar area, need not to set up the touch panel that the cooperation realized the fingerprint identification function at the front button department of mobile terminal or back specific area, consequently greatly reduced area and volume that fingerprint identification function and image shoot relevant function occupy on hardware outward appearance, the degree of difficulty of antenna design has been reduced simultaneously.

In addition, as another configuration of the touch panel 214, the touch panel 214 may also be a portion of the display screen corresponding to a specific area of the touch display screen 11 of the mobile terminal. In this setting, the display screen corresponding to the specific area and the sensor below the specific area are required to have very precise pressure sensing capability, so that the fingerprint recognition function of the fingerprint recognition module 213 can be started by means of the touch panel 214.
The foregoing is a detailed implementation of the imaging device and the mobile terminal including the same provided in the embodiments of the present application. In this embodiment, the screen cover 12 on the mobile terminal covers the area above the imaging device 21, so that a cover plate is not required to be specially arranged for the imaging device 21, which facilitates the manufacture of the mobile terminal and the imaging device 21, and thus, the implementation mode simplifies the manufacturing process and saves the process cost.
