The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

An electronic device 100 according to an embodiment of the application is described below with reference to fig. 1-9.

As shown in fig. 1 to 9, an electronic device 100 according to an embodiment of the first aspect of the present application includes: casing 1, mainboard 3, display screen 2, camera module 4 and light detect the piece.

Particularly, display screen 2 can establish the end of opening at casing 1, inject the installation space between display screen 2 and the casing 1, and mainboard 3 and camera module 4 are all established in the installation space, and display screen 2 links to each other with mainboard 3, and camera module 4 links to each other with mainboard 3. The display screen 2 may be used to display information input by or provided to the user, as well as other various menus. Further, the electronic device 100 may include a touch panel, which may cover the display screen 2, and when the touch panel detects a touch operation thereon or nearby, the touch panel transmits the touch operation to the processor to determine the type of the touch event, and then the processor provides a corresponding visual output on the display screen 2 according to the type of the touch event.

The camera module 4 includes a substrate 41, a photosensitive chip 42, and a lens assembly, wherein the photosensitive chip 42 is disposed on the substrate 41, and at least a portion of the photosensitive chip 42 is rotatable. For example, only a portion of the photo sensor chip 42 may be rotatable, or the entire photo sensor chip may be rotatable. The lens assembly is disposed on a side of the photosensitive chip 42 away from the substrate 41, and the lens assembly is connected to the substrate 41. The lens assembly may include a lens barrel 43 and a lens 44, the lens barrel 43 is connected to the substrate 41, the lens 44 is disposed at an end of the lens barrel 43 away from the photosensitive chip 42, when the camera module 4 works, light of an external environment may pass through the lens 44 and be incident on a photosensitive surface of the photosensitive chip 42, and the photosensitive chip 42 may convert an optical signal into an electrical signal, thereby implementing a shooting function.

When the at least one portion of the photosensitive chip 42 rotates, the angle of the photosensitive surface of the rotating portion of the photosensitive chip 42 changes, so that the effective photosensitive area of the photosensitive chip 42 changes. The initial position of the photosensitive chip 42 is a position parallel to the reference plane by using a plane perpendicular to the central axis of the lens 44 as the reference plane, and the entire photosensitive surface of the photosensitive chip 42 is parallel to the reference plane, and the effective photosensitive area of the photosensitive chip 42 is the largest. At least a part of the photosensitive chip 42 rotates by a certain angle, and an included angle is formed between at least a part of the photosensitive chip 42 after the rotation and the reference plane, that is, an included angle is formed between the photosensitive surface of at least a part of the photosensitive chip 42 after the rotation and the reference plane, and with respect to the effective photosensitive area of the photosensitive chip 42 at the initial position, the effective photosensitive area of the photosensitive chip 42 at this time is reduced, that is, the area of the photosensitive chip 42 for receiving light is reduced at this time.

The light detecting member is used for detecting the intensity of light in the external environment, and at least a part of the light sensing chip 42 rotates to correspondingly adjust the light sensing area according to the detection result of the light detecting member. Wherein, the light detects the piece and establishes in above-mentioned installation space and adjacent casing 1 or touch panel set up, and casing 1 or touch panel go up the position that corresponds with the light detects the piece and is provided with the light trap, and outside light can get into the light through this light trap and detect.

When using this electron device 100 to shoot, open camera module 4, light detection piece detects the intensity of external environment light, and according to the testing result of light detection piece, mainboard 3 control sensitization chip 42 above-mentioned some rotate certain angle with adjustment and light detection result assorted effective photosensitive area to make sensitization chip 42's effective photosensitive area can carry out corresponding adjustment according to the power of external environment light. The adjustment of the effective photosensitive area of the photosensitive chip 42 may be realized by adjusting the rotation angle of the photosensitive chip 42, or by adjusting the photosensitive areas of the photosensitive chips 42 with different rotation sizes, or by combining the two adjustment methods.

For example, when the external ambient light intensity is weak, the effective photosensitive area of the photo sensor 42 may be made larger (for example, the photo sensor 42 is in the initial position or rotated by a smaller angle, or a small area of the photo sensor 42 is rotated); when the intensity of the external ambient light is strong, the effective photosensitive area of the photo sensor chip 42 may be small (for example, the photo sensor chip 42 may be rotated by a large angle, or the entire photo sensor chip 42 or a large portion of the photo sensor chip 42 may be rotated). From this, through the power of external environment light, through the angle that the at least some rotation of control sensitization chip set for, can suitably adjust sensitization chip 42's effective photosensitive area, reduce the frequency that sensitization chip 42 wholly received light, when guaranteeing the imaging quality, can prolong sensitization chip 42's life.

It should be noted that the effective photosensitive area of the photosensitive chip 42 corresponding to the light intensity value can be written into the control module of the electronic device 100, after the light detection element detects the light intensity value, the light detection element can transmit the detection result to the control module of the motherboard 3, and the photosensitive chip 42 is controlled to rotate to adjust the corresponding effective photosensitive area according to a preset control program. When the camera module does not work, the photosensitive chip 42 is controlled to rotate to the initial position.

Alternatively, the photosensitive chip 42 may be a CCD (Charge-coupled Device) photosensitive chip. The CCD photosensitive chip has the advantages of self-scanning, wide sensing spectrum range, small distortion, small size, light weight, low system noise, low power consumption, long service life, high reliability and the like.

According to the electronic device 100 of the embodiment of the application, through the light detection piece that sets up, at camera module 4 during operation, through the testing result of light detection piece, through rotating at least partly of sensitization chip 42, can adjust the effective photosensitive area of sensitization chip 42 correspondingly, when guaranteeing imaging quality, can prolong the life of sensitization chip 42, improve the life of complete machine.

According to some embodiments of the present application, referring to fig. 8 and 9, the photosensitive chip 42 includes a plurality of photosensitive units 421 arranged in an array, and each photosensitive unit 421 is rotatable. Thus, by setting the plurality of photosensitive cells 421 of the photosensitive chip 42 to be rotatable, the adjustment of the effective photosensitive area of the photosensitive chip 42 can be controlled more accurately by controlling the rotation of each photosensitive cell 421.

Alternatively, one driving mechanism may be used to drive the photosensitive units 421 to rotate, and the plurality of photosensitive units 421 of the photosensitive chip 42 are driven to rotate by one driving mechanism. Thus, the simultaneous rotation of the plurality of photosensitive units 421 can be realized by one driving mechanism, and the embodiment can realize the adjustment of the effective photosensitive area of the photosensitive chip 42 by adjusting the rotation angle.

Alternatively, a plurality of driving mechanisms for driving the photosensitive units 421 to rotate are provided, and the plurality of driving mechanisms correspond to the plurality of photosensitive units 421 one by one. Therefore, each photosensitive unit 421 can be independently controlled by the corresponding driving mechanism, that is, the rotation of each photosensitive unit 412 is independently controlled, so that the photosensitive units 421 with different numbers can be controlled to rotate, thereby controlling the areas with different sizes of the photosensitive chips to rotate, and controlling the rotation angles of the photosensitive units 421 to be different, thereby more accurately adjusting the effective photosensitive areas of the photosensitive chips 42.

For example, according to the detection result of the light detecting element, a corresponding number of the photosensitive units 421 can be controlled to rotate, and the larger the number of the rotating photosensitive units 421 is, the smaller the effective photosensitive area of the photosensitive chip 42 is, so that the effective photosensitive area of the photosensitive chip 42 can be conveniently adjusted by controlling the number of the rotating photosensitive units 421.

For another example, according to the detection result of the light detecting element, the rotation angle of each photosensitive unit 421 can be controlled, and the larger the rotation angle of the photosensitive unit 421 is, the smaller the effective photosensitive area of the photosensitive chip 42 is, so that the effective photosensitive area of the photosensitive chip 42 can be conveniently adjusted by controlling the rotation angle of the photosensitive unit. The rotation angle of each photosensitive unit 421 may be the same or different.

For another example, the number of rotations and the rotation angle of the photosensitive unit 421 can be controlled simultaneously according to the detection result of the light detecting member, so that the effective photosensitive area of the photosensitive chip 42 can be adjusted more accurately.

According to some alternative embodiments of the present application, the rotation angle of each of the photosensitive units 421 ranges from 0 to 45 °. From this, with the turned angle setting of sensitization unit 421 in above-mentioned within range, can reduce the whole frequency and the area of receiving light of sensitization chip 42 to can prolong the life of camera module, can guarantee simultaneously that the effective photosensitive area of sensitization chip 42 can satisfy the operation requirement, guarantee imaging quality. It should be noted that the rotation angle of the photosensitive unit 421 refers to an angle rotated by the photosensitive unit 421 to an initial position after the photosensitive unit 421 rotates to a preset position, and the initial position of the photosensitive unit 421 is a position where the photosensitive unit 421 is parallel to the reference plane.

According to some alternative embodiments of the present application, the photosensitive surface of the photosensitive unit 421 is adapted to rotate toward a direction adjacent to the center of the photosensitive chip 42. It can be understood that the light passing through the lens 44 is generally adjacent to the center line of the lens assembly, and by making the photosensitive surface of the photosensitive unit 421 suitable for rotating toward the direction adjacent to the center of the photosensitive chip 42, the effective photosensitive area of the photosensitive unit 421 can be reduced, and at the same time, the amount of light received by the photosensitive unit 421 can be ensured, and the imaging quality can be ensured.

According to some alternative embodiments of the present application, referring to fig. 8, the photosensitive area of each photosensitive unit 421 of the photosensitive chip 42 is the same. For example, each of the photosensitive units 421 may be provided to be the same in shape and size. Therefore, the photosensitive chip 42 has a simple structure, is convenient to process and has low manufacturing cost.

According to some alternative embodiments of the present application, referring to fig. 9, a light sensing area of the light sensing unit 421 adjacent to the center line of the lens assembly is larger than a light sensing area of the light sensing unit 421 away from the center line of the lens assembly. It is understood that the light passing through the lens 44 is generally adjacent to the center line of the lens assembly, and the light sensing efficiency of the light sensing chip 42 can be improved by setting the light sensing area of the light sensing unit 421 adjacent to the center line of the lens assembly to be larger.

According to some embodiments of the present application, referring to fig. 5 to 7, the lens assembly and the substrate 41 define an accommodating space 4s therebetween, and the camera module 4 includes: a light-gathering part 45 and a first driving part 45a, wherein the first driving part 45a is connected with the light-gathering part 45 to drive the light-gathering part 45 to rotate. The light-gathering member 45 is rotatably disposed in the accommodating space 4s between a first storage position and a first expansion position, when the light-gathering member 45 is located at the first expansion position, at least a part of the light-gathering member 45 is opposite to the lens 44, and the light-gathering member 45 is adapted to gather and refract light passing through the lens assembly onto the photosensitive chip 42. The first driving member 45a communicates with the light detecting member, and when the intensity value of the external environment light detected by the light detecting member is smaller than a first set threshold, the first driving member 45a drives the light converging member 45 to rotate to a first unfolding position. From this, through spotlight piece 45 and the first driving piece 45a that sets up, when external light is less strong, through spotlight 45's spotlight effect, can shine to photosensitive chip 42's sensitization face after the light gathering, photosensitive chip 42 can only open the region that light after the gathering penetrated this moment, both can make some regional work of photosensitive chip 42, thereby can prolong photosensitive chip 42's life, can also improve photosensitive chip 42's sensitization efficiency simultaneously, improve the imaging quality.

For example, when the camera module 4 does not operate, the first driving member 45a drives the light focusing member 45 to rotate to the first receiving position, and at this time, the light focusing member 45 can be received in a portion adjacent to the sidewall of the receiving space 4s, and the normal operation of the lens 44 is not affected. When the camera module 4 works, whether the light gathering member 45 needs to be rotated to the first unfolding position is judged according to a comparison result of a light intensity value detected by the light detecting member and a first set threshold value, when the light intensity value detected by the light detecting member is smaller than the first set threshold value, the first driving member 45a drives the light gathering member 45 to rotate to the first unfolding position, and at the moment, light passing through the lens 44 can be gathered and refracted to a part of area of the photosensitive chip 42 through the light gathering effect of the light gathering member 45, so that an optical signal is converted into an electric signal, and a shooting function is realized; when the light intensity value detected by the light detecting element is greater than or equal to the first set threshold value, the first driving element 45a drives the light gathering element 45 to rotate to the first accommodating position, and the light passing through the lens 44 can directly irradiate to the corresponding area of the photosensitive chip 42, so that the optical signal is converted into an electrical signal, and the shooting function is realized.

Alternatively, the light-condensing member 45 may be a convex lens. This simplifies the structure of the light collector 45.

Alternatively, the first drive member 45a may be a motor.

According to some embodiments of the present application, referring to fig. 5 to 7, the lens assembly and the substrate 41 define an accommodating space 4s therebetween, and the camera module 4 includes: a light scattering member 46 and a second driving member 46a, the second driving member 46a being connected to the light scattering member 46 to drive the light scattering member 46 to rotate. The light scattering member 46 is rotatably disposed in the accommodating space 4s between a second storage position and a second expansion position, at least a portion of the light scattering member 46 is opposite to the lens 44 when the light scattering member 46 is in the second expansion position, and the light scattering member 46 is adapted to divergently refract the light passing through the lens assembly onto the photosensitive chip 42. The second driving member 46a is in communication with the light detecting member, and when the intensity value of the external ambient light detected by the light detecting member is greater than a second set threshold, the second driving member 46a drives the light scattering member 46 to rotate to a second unfolded position. From this, through the astigmatic piece 46 and the second driving piece 46a that set up, when external light is stronger, disperse the light through astigmatic piece 46, can disperse the light and shine to the different regions of photosensitive chip 42, can avoid the stronger life-span that influences photosensitive chip 42 of light, can prolong photosensitive chip 42's life, can also improve photosensitive chip 42's sensitization efficiency simultaneously, improve the imaging quality.

For example, when the camera module 4 does not operate, the second driving member 46a drives the light-scattering member 46 to rotate to the second receiving position, and at this time, the light-scattering member 46 can be received in a portion adjacent to the sidewall of the receiving space 4s, and the normal operation of the lens 44 will not be affected. When the camera module 4 works, whether the light scattering member 46 needs to be rotated to the second unfolding position is judged according to the comparison result of the light intensity value detected by the light detecting member and the second set threshold, when the light intensity value detected by the light detecting member is greater than the second set threshold, the second driving member 46a drives the light scattering member 46 to rotate to the second unfolding position, and at the moment, the light passing through the lens 44 can be scattered and refracted to a plurality of different areas of the photosensitive chip 42 through the light scattering effect of the light scattering member 46, so that the optical signal is converted into an electrical signal, and the shooting function is realized; when the light intensity value detected by the light detecting element is less than or equal to the second set threshold, the second driving element 46a drives the light scattering element 46 to rotate to the second storage position, and the light passing through the lens 44 can directly irradiate the corresponding area of the photosensitive chip 42, so that the optical signal is converted into an electrical signal, and the shooting function is realized.

Alternatively, the light dispersion member 46 may be a concave lens. This simplifies the structure of the diffuser 46.

Alternatively, the second driver 46a may be a motor.

According to some embodiments of the present application, referring to fig. 2 to 4, the display screen 2 includes a first display area 21 and a second display area 22, the camera module 4 is disposed on a side of the display screen 2 adjacent to the main board 3, and the lens 44 of the lens assembly is opposite to the first display area 21. Therefore, the problem that the front panel (the front panel can be the touch panel) of the electronic device 100 is occupied due to the installation mode of the camera module 4 of the traditional electronic device 100 can be avoided, so that the screen occupation ratio of the electronic device 100 can be improved, and the electronic device 100 can be favorably used for realizing a full-screen.

When the camera module 4 is in the working state, the resolution of the first display area 21 is smaller than that of the second display area 22; when the camera module 4 is in the non-operating state, the resolution of the first display area 21 is the same as the resolution of the second display area 22.

Therefore, the resolution of the first display area 21 is adjusted according to whether the camera module 4 is in the working state. Specifically, when the camera module 4 is in a working state, the resolution of the first display area 21 can be reduced, so that the light transmittance of the first display area 21 can be improved, and the imaging quality of the camera module 4 can be ensured; when camera module 4 is in the non-operating condition, improve the resolution ratio of first display area 21, can guarantee the display effect of first display area 21, and make the resolution ratio of first display area 21 the same with the resolution ratio of second display area 22 simultaneously to can guarantee the uniformity of the display effect of whole display screen 2, promote user experience.

The size of the first display area 21 can be set according to the size of the lens 44 of the camera module 4.

Alternatively, the display screen 2 may be an OLED screen. Because the OLED screen does not need a backlight source for the self-luminous screen, a backlight plate adopted by the display screen 2 in the related technology is omitted, the thickness of the display screen 2 is reduced, and the light transmittance of the display screen 2 is improved.

Alternatively, referring to fig. 3, the first display area 21 may be disposed adjacent to the edge of the display screen 2, so that when the camera module 4 is in an operating state, the influence of the first display area 21 on the entire effect of the display screen 2 may be reduced.

Alternatively, referring to fig. 2, the edge of the display screen 2 may extend to the inner side wall of the case 1. From this, the screen of display screen 2 accounts for and can be close or reach 100% for electronic device 100 really realizes the full screen, has further promoted the pleasing to the eye degree of display screen 2, has enlarged the display range of display screen 2 simultaneously, promotes user's experience. In addition, the volume of the electronic device 100 can be reduced, the electronic device 100 can be miniaturized, and the electronic device is convenient for a user to carry.

According to some optional embodiments of the present application, the lens 44 of the camera module 4 is movable in a plane parallel to the first display area 21, and when the camera module 4 is in the working state, the camera module 4 is adapted to capture at least two initial photos through different positions of the first display area 21, and then synthesize a target photo without interference of the pixels of the first display area 21 according to the at least two initial photos. Therefore, when a user uses the electronic device 100 to shoot, external light can pass through the gaps between the working pixel units or the gaps between the working sub-pixels in the first display area 21 of the display screen 2 and enter the lens 44 of the camera module 4, and the shooting of the first picture can be completed after the processing of the camera module 4. Then the lens 44 of the camera module 4 moves to a position in a plane parallel to the first display area 21, the position is different from the position of the first picture, and the second picture is taken, so on, a plurality of pictures can be taken at a plurality of positions, and the effective pixels of the plurality of pictures are synthesized by a software algorithm, so that a clear and complete picture can be obtained.

It should be noted that, when the camera module 4 takes a first shot, the opened pixel units or sub-pixels in the first display area 21 may block part of the light, the lens 44 of the camera module 4 is moved to enable the lens 44 to be located at different positions to collect photos with more complete information, and a target photo that is not interfered by the working pixels in the first display area 21 can be obtained by synthesizing a plurality of photos, so that the imaging quality is significantly improved.

Optionally, the camera module 4 includes a voice coil motor connected to the lens 44 to drive the lens 44 to move in a plane parallel to the first display area 21. For example, the center of the voice coil motor may be provided with a receiving cavity, the lens 44 of the camera module 4 may be disposed in the receiving cavity, and the voice coil motor may drive the lens 44 to move in the receiving cavity. Therefore, the voice coil motor can drive the lens 44 to move smoothly along the plane parallel to the first display area 21, and the space occupied by the voice coil motor is small, so that the compactness of the camera module 4 can be improved, and the camera module 4 is miniaturized.

In other embodiments of the present application, referring to fig. 1, the camera module 4 may also be disposed at one side of the display screen 2 and located at an inner side of the touch panel (the inner side is a direction adjacent to a center of the electronic device 100), and a light-passing hole suitable for light to pass through is formed on the touch panel of the electronic device 100, the light-passing hole is opposite to the lens 44 of the camera module 4, and external light can enter the camera module 4 through the light-passing hole.
