Description

Technical Field

[0001] This application relates to the field of camera technology, and in particular to a camera module and electronic device. Background Technology

[0002] With the rapid development of camera technology, more and more electronic devices such as smartphones, tablets, and e-readers are adopting periscope-style camera modules to meet the needs of telephoto photography. Periscope-style camera modules typically have a prism at the front of the lens group. The prism reflects light, deflecting it from the thickness direction of the electronic device to its length and width directions, thus compressing the device's thickness. In some related technologies, periscope-style camera modules achieve optical image stabilization by moving the prism.

[0003] However, in traditional periscope camera modules, the design of achieving optical image stabilization by driving the movement of a prism is prone to loss of sharpness, affecting the imaging quality of the camera module. Utility Model Content

[0004] This application provides a camera module and electronic device to solve the problem that optical image stabilization achieved by driving prism movement in camera modules can easily affect image quality.

[0005] A camera module, comprising:

[0006] case;

[0007] A prism mechanism, disposed on the housing, has an incident light surface, an exit light surface, and at least one reflecting surface. At least a portion of the light rays incident on the prism mechanism from the incident light surface are reflected by at least one of the reflecting surfaces and exit from the exit light surface. One of the incident light surface and the exit light surface is convex, and the other is concave.

[0008] An image stabilization drive mechanism is used to drive the prism mechanism to move relative to the housing to achieve optical image stabilization.

[0009] An electronic device includes a camera module as described in any of the above embodiments.

[0010] In the aforementioned camera module, both the incident and exit surfaces of the prism mechanism are curved. This allows the prism mechanism to regulate light while transmitting it, reducing the burden on the lens group within the camera module to deflect light. This, in turn, reduces the number of lenses in the lens group and compresses the axial dimensions of the camera module. Simultaneously, the curved surface on the prism mechanism at the front of the camera module allows it to contract the light beam on the object side of the lens group, reducing the aperture of the beam passing through the prism mechanism. This, in turn, reduces the effective light-passing aperture of the lens group and other components at the rear of the prism mechanism, further compressing the radial dimensions of the camera module. The fact that one of the incident and exit surfaces is convex and the other concave, along with the superposition of their positive and negative curvatures, helps suppress sharpness loss during optical image stabilization caused by the relative movement of the prism mechanism to the housing, thus improving the image quality of the camera module.

[0032] Please see Figure 1 , Figure 2 and Figure 3 , Figure 1 The following are schematic diagrams illustrating the structure of the electronic device 10 in some embodiments of this application. Figure 2 The following are schematic diagrams illustrating the structure of the camera module 20 in some embodiments of this application. Figure 3 The diagram shows structural schematics of the prism mechanism 21 and the image stabilization drive mechanism 22 in some embodiments of this application. The electronic device 10 provided in this application includes, but is not limited to, mobile terminals such as smartphones, tablets, and e-readers. The electronic device 10 may include a mid-frame 11, a display panel, and a back panel 12. Components such as the motherboard and battery of the electronic device 10 are disposed on the mid-frame 11, and the display panel and back panel 12 cover the opposite sides of the mid-frame 11. The back panel 12 has a light-transmitting hole 121. The camera module 20 is housed within the space formed by the back panel 12 and the mid-frame 11, and can collect ambient light through the light-transmitting hole 121, thereby enabling the electronic device 10 to have a camera function.

[0033] In some embodiments, the camera module 20 includes a prism mechanism 21 and a lens group (such as...). Figure 2 The first lens group 23 and the second lens group 24 shown, as well as the image sensor 25, are illustrated. The prism mechanism 21 is opposite to the light-transmitting aperture 121 and can deflect the light path at a specific angle. The specific deflection angle of the prism mechanism 21 can be designed according to the light path transmission requirements. Figure 2 The illustrated embodiment uses the prism mechanism 21 as an example to deflect the light path by 90°. A lens group is positioned between the prism mechanism 21 and the image sensor 25 along the light path propagation direction. Light entering the camera module 20 from the light-transmitting hole 121 is deflected by the prism mechanism 21 and then projected onto the lens group. After adjustment by the lens group, the light is projected onto the image sensor 25. The image sensor 25 converts the light signal into an electrical signal and transmits it to the motherboard of the electronic device 10, or to a chip in the electronic device 10 specifically used for processing image signals.

[0034] When the prism mechanism 21 is used to deflect the light path by 90°, the axis of the light-transmitting aperture 121 can be parallel to the thickness direction of the electronic device 10, and the axis of the lens group can be parallel to the length and width direction of the electronic device 10. Thus, the prism mechanism 21 can deflect the light path from the thickness direction of the electronic device 10 to the length and width direction, which is beneficial to compressing the space occupied by the camera module 20 in the thickness direction of the electronic device 10, realizing the periscope design. While realizing the telephoto function (for example, the camera module 20 provided in this application can adopt a medium telephoto design with an equivalent focal length of 70mm-100mm), it is also beneficial to compress the thickness of the electronic device 10, thereby facilitating the thin design of the electronic device 10.

[0035] In some embodiments, the camera module 20 further includes a housing 26 and an image stabilization drive mechanism 22. The prism mechanism 21 and the image stabilization drive mechanism 22 are both disposed on the housing 26. The image stabilization drive mechanism 22 is used to drive the prism mechanism 21 to move relative to the housing 26 to achieve optical image stabilization.

[0036] In some embodiments, the prism mechanism 21 has an incident surface 211, an exiting surface 212, and a reflecting surface 213. The incident surface 211 is opposite to the light-transmitting aperture 121, and the exiting surface 212 is opposite to the lens group. At least a portion of the light rays incident on the prism mechanism 21 from the incident surface 211 can be reflected by at least one reflecting surface 213 and then exited from the exiting surface 212. The reflecting surface 213 can be a plane. Both the incident surface 211 and the exiting surface 212 can be planes or curved surfaces. The plane perpendicular to the axis of the incident surface 211, the plane perpendicular to the axis of the exiting surface 212, and the plane containing the reflecting surface 213 intersect each other.

[0037] For example, when the prism mechanism 21 is used to deflect the light path by 90°, the axis of the light-incident surface 211 can be parallel to the axis of the light-transmitting aperture 121, the axis of the light-exiting surface 212 can be parallel to the axis of the lens group, the plane perpendicular to the axis of the light-incident surface 211 can be perpendicular to the plane perpendicular to the axis of the light-exiting surface 212, and both the plane perpendicular to the axis of the light-incident surface 211 and the plane perpendicular to the axis of the light-exiting surface 212 can form a 45° angle with the reflecting surface 213.

[0038] Driven by the image stabilization drive mechanism 22, the movement of the prism mechanism 21 relative to the housing 26 is unlimited and can be specifically configured according to the optical image stabilization requirements of the camera module 20. For example, in some embodiments, the image stabilization drive mechanism 22 is used to drive the prism mechanism 21 to rotate relative to the housing 26 around a first axis and / or a second axis to achieve optical image stabilization. The first axis and the second axis are two mutually perpendicular straight lines on a plane parallel to the reflecting surface 213. Figure 3The first axis is indicated by a dashed double arrow, and the second axis can be understood as a straight line perpendicular to the plane of the paper. With this configuration, the movement of the prism mechanism 21 relative to the housing 26, driven by the image stabilization drive mechanism 22, can meet the optical image stabilization requirements of the camera module 20.

[0039] The specific configuration of the image stabilization drive mechanism 22 is not limited, as long as it can meet the motion drive requirements of the prism mechanism 21. For example, the image stabilization drive mechanism 22 can use any suitable drive element, including but not limited to a voice coil motor, shape memory alloy, piezoelectric ceramic driver, electromagnetic driver, etc., to drive the prism mechanism 21 to move relative to the housing 26.

[0040] In the embodiments shown in the accompanying drawings, the prism mechanism 21 is exemplified by having a reflecting surface 213. The prism mechanism 21 can be approximately triangular prism in shape, and the light-incident surface 211, the light-exiting surface 212, and the reflecting surface 213 can be the three sides of the prism mechanism 21. In other embodiments, the prism mechanism 21 may also include two or more reflecting surfaces 213, allowing light to be reflected sequentially on multiple reflecting surfaces 213 before exiting. The specific design can be tailored to the light transmission requirements and is not limited in this application.

[0041] Furthermore, in some embodiments, one of the light-incident surface 211 and the light-exit surface 212 of the prism mechanism 21 is a convex surface, and the other is a concave surface. In this application, the surface of the prism mechanism 21 that protrudes away from the prism mechanism 21 is called a convex surface, and the surface that is concave towards the prism mechanism 21 is called a concave surface. In the embodiments shown in the accompanying drawings of this application, the light-incident surface 211 is a convex surface and the light-exit surface 212 is a concave surface as an example. In other embodiments, the light-incident surface 211 may also be set as a concave surface, and the light-exit surface 212 may be set as a convex surface.

[0042] In the aforementioned camera module 20, both the light-incident surface 211 and the light-exit surface 212 of the prism mechanism 21 are curved surfaces. This allows the prism mechanism 21 to regulate light while transmitting it, reducing the burden on the lens group in the camera module 20 to deflect light. This, in turn, helps to reduce the number of lenses in the lens group and compress the axial dimension of the camera module 20. Simultaneously, the curved surface on the prism mechanism 21 at the front end of the camera module 20 allows the prism mechanism 21 to contract the light beam on the object side of the lens group. This helps to reduce the aperture of the light beam passing through the prism mechanism 21, thereby reducing the effective light-transmitting aperture of the lens group and other components at the rear end of the prism mechanism 21. This further helps to compress the radial dimension of the camera module 20 (for example, the height of a camera module 20 with a 1 / 1.28-inch image sensor 25 can be reduced to less than 12.5 mm). One of the light-incident surface 211 and the light-exit surface 212 is convex and the other is concave. The superposition of the positive and negative curvatures of the light-incident surface 211 and the light-exit surface 212 is also conducive to making the light beam passing through the prism mechanism 21 tend to be a parallel beam. Compared with the converging or diverging beam, it is beneficial to suppress the loss of sharpness in the process of the prism mechanism 21 moving relative to the housing 26 to achieve the optical image stabilization function, and to improve the imaging quality of the camera module 20.

[0043] refer to Figure 4 As shown, in some embodiments, the prism mechanism 21 includes a prism body 214, a first lens structure 218, a second lens structure 219, and two adhesive structures 216. The prism body 214 may be generally triangular prism in shape, and a reflecting surface 213 is disposed on the prism body 214, for example, one side of the prism body 214 forms the reflecting surface 213. The first lens structure 218 and the second lens structure 219 are bonded to the prism body 214 one-to-one through the two adhesive structures 216, for example, one-to-one bonded to the other two sides of the prism body 214. The light-incident surface 211 is disposed on the side surface of the first lens structure 218 facing away from the prism body 214, and the light-exit surface 212 is disposed on the side surface of the second lens structure 219 facing away from the prism body 214.

[0044] This design allows the formation processes of the light-incident surface 211 and the light-exit surface 212 to be separated from the fabrication process of the prism body 214. The first lens structure 218, the second lens structure 219, and the prism mechanism 21 are fabricated separately, and then combined using methods such as adhesive bonding. For example, the fabrication processes of the first lens structure 218 and the second lens structure 219 can be flexibly set according to the complexity of the surface shapes of the light-incident surface 211 and the light-exit surface 212. Any applicable process, such as injection molding or cold glass processing, can be used to fabricate the first lens structure 218 and the second lens structure 219. The formation processes of the light-incident surface 211 and the light-exit surface 212 are not limited by the cold glass processing or other processes of the prism body 214, which improves the flexibility of the light-incident surface 211 and the light-exit surface 212 and meets different light adjustment needs. Meanwhile, compared to directly processing curved prisms through injection molding and other processes, the prism mechanism 21 with a first lens structure 218 and a second lens structure 219 provided in this embodiment effectively reduces the manufacturing difficulty and cost. Furthermore, compared to directly manufacturing curved prisms through molding, the materials of the first lens structure 218 and the second lens structure 219 in the prism mechanism 21 provided in this embodiment are not limited by the requirement for softer glass materials in molding processes, which improves the flexibility and reliability of surface design.

[0045] It should be noted that, in the curved surfaces formed in the first lens structure 218 and the second lens structure 219, if the surface complexity is low (e.g., spherical) and / or the radius of curvature is large, a glass cold processing process can be used to effectively reduce manufacturing costs. However, when the curved surfaces formed in the first lens structure 218 and the second lens structure 219 have a high surface complexity (e.g., aspherical) and / or a small radius of curvature, an injection molding process can be used to improve the design flexibility and molding accuracy of the surface, thereby improving the imaging quality of the camera module 20.

[0046] In some embodiments, the first lens structure 218, the second lens structure 219, and the prism body 214 can be aligned by means of optical alignment, so that the axes of the first lens structure 218 and the second lens structure 219 overlap with the optical axis of the camera module 20. Then, the first lens structure 218, the second lens structure 219, and the prism body 214 are bonded together by the adhesive structure 216 to improve the imaging quality of the camera module 20.

[0047] exist Figure 4In the illustrated embodiment, the prism mechanism 21 is provided with a first lens structure 218 and a second lens structure 219, with the light-incident surface 211 and the light-exit surface 212 formed on the first lens structure 218 and the second lens structure 219 respectively, as an example. Of course, the light-incident surface 211 and the light-exit surface 212 may also be formed on only one of the lens structures and the other on the prism body 214. In this case, the prism mechanism 21 may only have one lens structure, which is beneficial to improving the design flexibility and molding cost of the curved surface formed on the lens structure.

[0048] In other embodiments, the prism mechanism 21 may also be an integral structure, in which case the light-incident surface 211, the light-exiting surface 212, and the reflecting surface 213 are formed on an integral prism. The prism mechanism 21 can be made by glass cold working process or by injection molding process.

[0049] refer to Figure 5 As shown, in some embodiments, the prism mechanism 21 includes a lens structure, with one of the light-incident surface 211 and the light-exit surface 212 being convex and located on the side of the lens structure facing away from the prism body 214, while the other is concave and located on the prism body 214. Figure 5 In the illustrated embodiment, the light-incident surface 211 is convex and formed on the first lens structure 218, while the light-exiting surface 212 is concave and disposed on the prism body 214, serving as an example. In other embodiments, the light-incident surface 211 may also be concave and formed on the prism body 214, while the light-exiting surface is convex and formed on the second lens structure 219. Since the prism body 214 is a triangular prism shape, it is easier and cheaper to form a concave surface on the prism body 214 through processes such as cold glass processing. This configuration improves the flexibility of setting the convex surface of the prism mechanism 21, reduces the difficulty and cost of forming the convex surface, and also allows the concave surface to be formed through cold glass processing, which helps to reduce the overall manufacturing difficulty and cost of the prism body 214.

[0050] In other embodiments, one of the light-incident surface 211 and the light-exit surface 212 is located on the side of the lens structure facing away from the prism body 214, and the other is located on the prism body 214. Furthermore, the radius of curvature of the light-incident surface 211 located on the prism body 214 is greater than the radius of curvature of the light-exit surface 212 located on the lens structure. For example, when the radius of curvature of the convex surface in the light-incident surface 211 and the light-exit surface 212 is greater than the radius of curvature of the concave surface, i.e., the curvature of the concave surface is steeper than that of the convex surface, the convex surface of the light-incident surface 211 and the concave surface of the light-exit surface 212 is located on the prism body 214, and the concave surface is located on the lens structure. When the radius of curvature of the convex surface in the light-incident surface 211 and the light-exit surface 212 is smaller than the radius of curvature of the concave surface, that is, when the curvature of the convex surface is steeper than that of the concave surface, one of the convex surfaces in the light-incident surface 211 and the light-exit surface 212 is provided on the lens structure, and the other of the concave surface is provided on the prism body 214.

[0051] For example, in some embodiments, the radius of curvature of the light-incident surface 211 is smaller than that of the light-exiting surface 212. The light-incident surface 211 is formed on the first lens structure 218, and the light-exiting surface 212 is formed on the prism body 214. In other embodiments, the radius of curvature of the light-incident surface 211 is larger than that of the light-exiting surface 212. The light-incident surface 211 is formed on the prism body 214, and the light-exiting surface is formed on the second lens structure 219. This arrangement improves the design flexibility of the surface with the steeper curvature (light-incident surface 211 or light-exiting surface 212) and reduces molding difficulty and cost. The surface with the gentler curvature can be formed on the prism body 214 through methods such as cold glass processing, which also reduces the overall fabrication difficulty and cost of the prism mechanism 21.

[0052] In some embodiments, one of the light-incident surface 211 and the light-exit surface 212 is disposed on the side of the lens structure facing away from the prism body 214, and the other is disposed on the prism body 214. The light-incident surface 211 and the light-exit surface 212 disposed on the prism body 214 are spherical, and the light-exit surface 212 disposed on the lens structure are aspherical.

[0053] For example, in some embodiments, the light-incident surface 211 is aspherical and is disposed on the first lens structure 218, while the light-exiting surface 212 is spherical and is disposed on the prism body 214. In other embodiments, the light-exiting surface 212 is aspherical and is disposed on the second lens structure 219, while the light-incident surface 211 is spherical and is disposed on the prism body 214. This arrangement allows for the formation of more complex aspherical surfaces on the lens structure. By fabricating the lens structure separately, the design flexibility of the aspherical surfaces can be improved, meeting the precision requirements for aspherical surface fabrication while reducing fabrication difficulty and cost. The spherical surface can be formed on the prism body 214 through methods such as cold glass processing, which also helps to reduce the overall fabrication difficulty and cost of the prism mechanism 21.

[0054] Of course, for reference Figure 6 As shown, in some embodiments, the convex surface of the light-incident surface 211 and the convex surface of the light-outcident surface 212 can also be formed on the prism body 214, and the forming process includes, but is not limited to, cold working of glass. The concave surface can also be formed on the lens structure, and the forming process includes, but is not limited to, cold working of glass or injection molding. This can also reduce the design flexibility of one of the curved surfaces, and reduce the manufacturing difficulty and manufacturing cost. Figure 6 In the illustrated embodiment, the light-incident surface 211 is convex and formed on the prism body 214, while the light-exiting surface 212 is concave and formed on the second lens structure 219. In other embodiments, the light-incident surface 211 may also be concave, while the light-exiting surface 212 may be convex.

[0055] Combination Figure 4 and Figure 7 As shown, in some embodiments, the prism mechanism 21 further includes a light-shielding layer 217. The light-shielding layer 217 is disposed between the prism body 214 and the lens structure, and is arranged around the periphery of the surface of the lens structure facing the prism body 214. The inner light-transmitting portion of the light-shielding layer 217 defines the effective light-transmitting area of ​​the prism mechanism 21. For example, when the prism mechanism 21 includes a first lens structure 218, the light-shielding layer 217 is disposed between the prism body 214 and the first lens structure 218, and is arranged around the edge of the first lens structure 218. When the prism mechanism 21 includes a second lens structure 219, the light-shielding layer 217 is disposed between the prism body 214 and the second lens structure 219, and is arranged around the edge of the second lens structure 219.

[0056] As can be seen, when the prism mechanism 21 is divided into a lens structure and a prism body 214, it is also beneficial to set the light-shielding layer 217, which is used to block stray light outside the effective light-passing area, on the lens structure and the prism body 214, thereby improving the blocking effect of stray light and thus improving the imaging quality of the camera module 20. At the same time, the light-shielding layer 217 can also be protected by the lens structure and the prism body 214, reducing the risk of damage and failure of the light-shielding layer 217.

[0057] The light-shielding layer 217 includes, but is not limited to, light-shielding structures such as screen-printed ink or light-shielding coatings disposed on the lens structure. The location of the light-shielding layer 217 is not limited. In the accompanying drawings of this application, the light-shielding layer 217 is disposed between the adhesive structure 216 and the lens structure as an example. In fact, the light-shielding layer 217 can also be disposed between the adhesive structure 216 and the prism body 214.

[0058] Please see again. Figure 2In some embodiments, the lens group of the camera module 20 includes a first lens group 23 and a second lens group 24, which are sequentially arranged between the light-emitting surface 212 and the image sensor 25 along the optical path propagation direction. Both the first lens group 23 and the second lens group 24 may include one or more lenses with optical power. The first lens group 23 and the image sensor 25 are relatively fixed, and the second lens group 24 is configured to move along the optical axis between the first lens group 23 and the image sensor 25. For example, the second lens group 24 can achieve movement relative to the image sensor 25 through any suitable zoom or focus drive mechanism such as a voice coil motor or a piezoelectric actuator. This configuration enables optical internal focusing through one of the lens groups located in the prism mechanism 21 and the image sensor 25. This not only reduces the load on the focusing drive mechanism, lowers its cost and space requirements, but also reduces the space occupied by the focusing stroke in the axial direction. This helps to compress the space occupied by the camera module 20 in the electronic device 10 (for example, the axial dimension of the camera module 20 can be shortened to within 35mm), which is beneficial for the miniaturization design of the electronic device 10.

[0059] It should be noted that in this application Figures 4-6 In the illustrated embodiments, when the prism mechanism 21 includes a first lens structure 218 and / or a second lens structure 219, the radial dimension of the lens structure is smaller than the radial dimension of the surface of the prism body 214 used to house the lens structure. Therefore, the positive lenses of the first lens structure 218 and the second lens structure 219 on the prism body 214 both fall within the range of the prism body 214. In this way, the prism body 214 can provide effective support and protection for the lens structure, reducing the risk of lens structure damage. Simultaneously, the prism body 214 can effectively receive light from the lens structure. In other embodiments, the radial dimensions of the first lens structure 218 and / or the second lens structure 219 may also be smaller than the radial dimension of the corresponding surface of the prism body 214. In this case, the first lens structure 218 and / or the second lens structure 219 may partially protrude from the prism body 214. Thus, by setting a larger aperture lens structure, a wider range of light transmission can be achieved, meeting the requirements for a larger light transmission aperture and light flux. The specific configuration can be determined according to the light transmission requirements of the prism mechanism 21.

[0060] refer to Figure 8 , Figure 8This is a schematic diagram of the structure of an electronic device 10 provided in an embodiment of this application. The electronic device 10 may include a radio frequency (RF) circuit 501, a memory 502 including one or more computer-readable storage media, an input unit 503, a display unit 504, a sensor 505, an audio circuit 506, a wireless Fidelity (WiFi) module 507, a processor 508 including one or more processing cores, and a power supply 509, among other components. Those skilled in the art will understand that... Figure 8 The structure of the electronic device 10 shown does not constitute a limitation on the electronic device 10. It may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0061] The radio frequency (RF) circuit 501 can be used to send and receive information, or to receive and send signals during a call. Specifically, it receives downlink information from the base station and hands it over to one or more processors 508 for processing; additionally, it sends uplink data to the base station. Typically, the RF circuit 501 includes, but is not limited to, an antenna, at least one amplifier, a tuner, one or more oscillators, a Subscriber Identity Module (SIM) card, a transceiver, a coupler, a low-noise amplifier (LNA), a duplexer, etc. Furthermore, the RF circuit 501 can also communicate wirelessly with networks and other devices. This wireless communication can use any communication standard or protocol, including but not limited to GSM, GPRS, CDMA, WCDMA, LTE, email, and SMS.

[0062] Memory 502 can be used to store applications and data. The applications stored in memory 502 contain executable code. Applications can be composed of various functional modules. Processor 508 executes various functional applications and data processing by running the applications stored in memory 502. Memory 502 may primarily include a program storage area and a data storage area. The program storage area may store the operating system, applications required for at least one function (such as sound playback, image playback, etc.), etc.; the data storage area may store data created based on the use of electronic device 10 (such as audio data, phonebook, etc.). Furthermore, memory 502 may include high-speed random access memory and may also include non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device. Accordingly, memory 502 may also include a memory controller to provide access to memory 502 for processor 508 and input unit 503.

[0063] Input unit 503 can be used to receive input numbers, character information, or user characteristic information (such as fingerprints), and to generate keyboard, mouse, joystick, optical, or trackball signal inputs related to user settings and function control. Specifically, in one embodiment, input unit 503 may include a touch-sensitive surface and other input devices. The touch-sensitive surface, also known as a touch display or touchpad, can collect user touch operations on or near it (such as user operations using fingers, styluses, or any suitable object or accessory on or near the touch-sensitive surface) and drive corresponding connection devices according to a pre-set program. Optionally, the touch-sensitive surface may include a touch detection device and a touch controller. The touch detection device detects the user's touch orientation and the signal generated by the touch operation, transmitting the signal to the touch controller; the touch controller receives touch information from the touch detection device, converts it into touch point coordinates, sends it to the processor 508, and can receive and execute commands from the processor 508.

[0064] Display unit 504 can be used to display information input by the user or information provided to the user, as well as various graphical user interfaces of electronic device 10. These graphical user interfaces can be composed of graphics, text, icons, video, and any combination thereof. Display unit 504 may include a display panel. Optionally, the display panel can be configured in the form of a liquid crystal display (LCD), organic light-emitting diode (OLED), etc. Further, a touch-sensitive surface can cover the display panel. When the touch-sensitive surface detects a touch operation on or near it, it transmits the information to processor 508 to determine the type of touch event. Subsequently, processor 508 provides corresponding visual output on the display panel according to the type of touch event. Although in Figure 8 In this context, the touch-sensitive surface and the display panel are two separate components for implementing input and output functions. However, in some embodiments, the touch-sensitive surface and the display panel can be integrated to achieve both input and output functions.

[0065] The electronic device 10 may also include at least one sensor 505, such as a light sensor, a motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor and a proximity sensor. The ambient light sensor can adjust the brightness of the display panel according to the ambient light level, and the proximity sensor can turn off the display panel and / or backlight when the electronic device 10 is moved to the ear. As a type of motion sensor, a gravity acceleration sensor can detect the magnitude of acceleration in various directions (generally three axes). When stationary, it can detect the magnitude and direction of gravity and can be used for applications that recognize the phone's posture (such as landscape / portrait switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc. Other sensors that may be configured in the electronic device 10, such as gyroscopes, barometers, hygrometers, thermometers, and infrared sensors, will not be described in detail here.

[0066] Audio circuit 506 provides an audio interface between the user and electronic device 10 via a speaker and microphone. Audio circuit 506 converts received audio data into electrical signals, transmits them to the speaker, and the speaker outputs them as sound signals. Conversely, the microphone converts collected sound signals into electrical signals, which are then received by audio circuit 506, converted back into audio data, and processed by processor 508. The audio data is then transmitted via radio frequency circuit 501 to, for example, another electronic device 10, or output to memory 502 for further processing. Audio circuit 506 may also include a headphone jack to facilitate communication between peripheral headphones and electronic device 10.

[0067] WiFi (Wireless Fidelity) is a short-range wireless transmission technology. Electronic device 10, through WiFi module 507, can help users send and receive emails, browse web pages, and access streaming media, providing users with wireless broadband internet access. Although Figure 8 The wireless fidelity module 507 is shown, but it is understood that it is not a necessary component of the electronic device 10 and can be omitted as needed without changing the nature of the invention.

[0068] The processor 508 is the control center of the electronic device 10. It connects various parts of the electronic device 10 via various interfaces and lines. By running or executing applications stored in the memory 502 and calling data stored in the memory 502, it performs various functions and processes data of the electronic device 10, thereby providing overall monitoring of the electronic device 10. Optionally, the processor 508 may include one or more processing cores; preferably, the processor 508 may integrate an application processor and a modem processor, wherein the application processor mainly handles the operating system, user interface, and applications, while the modem processor mainly handles wireless communication. It is understood that the modem processor may not be integrated into the processor 508.

[0069] The electronic device 10 also includes a power supply 509 that supplies power to the various components. Preferably, the power supply 509 can be logically connected to the processor 508 through a power management system, thereby enabling functions such as charging, discharging, and power consumption management through the power management system. The power supply 509 may also include one or more DC or AC power supplies, recharging systems, power fault detection circuits, power converters or inverters, power status indicators, and other arbitrary components.

[0070] although Figure 8 As not shown in the diagram, the electronic device 10 may also include a Bluetooth module, etc., which will not be described in detail here. In specific implementation, the above modules can be implemented as independent entities, or they can be arbitrarily combined and implemented as the same or several entities. For the specific implementation of the above modules, please refer to the previous method embodiments, which will not be described in detail here.

[0071] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
