Detailed Implementation
[0019] The embodiments of this application will now be described in detail with reference to the accompanying drawings.
[0020] Figures 1-4 The schematic diagram of the electronic device structure is a logical structure illustration; the specific connection structure is based on the actual production structure. In the following description, specific details such as particular system structures, interfaces, and technologies are presented for illustrative purposes rather than limiting, in order to provide a thorough understanding of this application.
[0021] This application provides an electronic device; please refer to [link / reference]. Figure 1 , Figure 1 This is a schematic diagram of one embodiment of the electronic device of this application.
[0022] The electronic device 100 includes an identification module 101 and a display screen 102. The identification module 101 is used to identify viewing angle information and display information, and to detect the display scene by identifying the viewing angle information and display information. The recognition module 101 may include various sensors and a coupled processor. Sensors used to recognize perspective information may be one or more sensors such as a camera, infrared camera, depth sensor, and light sensor, which acquire information and then perform recognition via the processor. It may also include fingerprint sensors, gravity sensors, accelerometers, temperature sensors, etc., to provide more device or interactive information for multimodal perception and recognition. The display information used for recognition may be acquired through a program and interface running within the processor of the electronic device 100, by acquiring the interface control structure and data, or by using screen reading, screen recording, or text recognition auxiliary functions. In some embodiments, text recognition algorithms such as YOLOv5 may be used for content semantic recognition.
[0023] Display screen 102 is coupled to recognition module 101 and is used to display information.
[0024] When the viewing angle information of the display screen 102 does not meet the preset safety range, privacy protection is achieved by reducing the light transmittance of the display screen 102 globally or partially, or by fogging or even turning off the screen.
[0025] The preset security range can be set based on the user's line of sight at 0° when their eyes are directly facing the center of the screen, and shifted 30 to 45 degrees to the left or right. The specific preset security range can be determined based on factors such as the level of privacy protection and the screen size.
[0026] In some embodiments, the privacy protection layer on the surface of the display screen 102 can be a PDLC (Electrochromic Device) layer, which is formed by dispersing liquid crystal microdroplets in a polymer to form a thin film. When the power is off, the liquid crystal molecules are disordered, which strongly scatters light, and the glass has an opaque, frosted display effect; when the power is on, the electric field causes the liquid crystal molecules to align in an orderly manner, and light can pass through directly, and the glass becomes transparent.
[0027] In some embodiments, the privacy protection layer on the surface of the display 102 may be an EC (Electrochromism) layer, comprising a color-changing layer and a storage layer. When a voltage is applied, ions and electrons are injected into the electrochromic layer, triggering a chemical reaction that colors it, thereby absorbing light; when the voltage is reversed, the ions and electrons are extracted, and the material returns to transparency.
[0028] In some embodiments, the PDLC layer and EC layer are combined for privacy protection, and a composite display structure is used to dynamically adjust the privacy protection area to achieve global protection and local detail protection.
[0029] By combining the recognition module 101 and the display screen 102, the electronic device 100 maintains clear visibility while ensuring privacy protection. The privacy protection strategy based on the recognition of the displayed information content reduces the risk of sensitive information leakage, automatically protects privacy, and reduces the usage rate of users turning off the function due to cumbersome operation.
[0030] Please see Figure 2 , Figure 2 This is a schematic diagram of the display screen structure of one embodiment of the electronic device of this application.
[0031] In one optional embodiment, the display screen 102 includes a fogging layer 1021 and a light-transmitting layer 1022. The fogging layer 1021 is used for global fogging display, and the light-transmitting layer 1022 is used for global or local light transmission display of corresponding display information areas.
[0032] The screen is divided into multiple independent pixel units, each equipped with an independent driving circuit, supporting three modes: global fogging, local blurring, and light transmission enhancement, balancing privacy protection precision and display efficiency. The pixel unit area is determined based on the display screen area 102, control complexity, and privacy protection precision. In one embodiment, the area of a pixel unit in a mobile phone screen is 0.5 × 0.5 mm.
[0033] In some embodiments, the atomization layer 1021 of the display screen 102 can be a PDLC layer, the light-transmitting layer 1022 can be an EC layer, and a color display layer (not shown) such as an OLED or LCD screen is also provided at the bottom of the atomization layer 1021 and the light-transmitting layer 1022 to display information. A touch layer (not shown) is also provided on the surface of the atomization layer, through which interactive signals can be received. The atomization layer 1021 and the light-transmitting layer 1022 act as dynamically adjustable filters, adjusting the light emitted from the underlying display layer, thereby adjusting the display effect of the entire display screen 102.
[0034] The two layers are controlled by independent voltage sources. For example, in a payment scenario, the fogging layer 1021 maintains a global fogging state, while the light-transmitting layer 1022 performs a 0.5px Gaussian blur on the QR code area and maintains 85% light transmittance in the time display area.
[0035] PDLC layer itself is not a capacitor material, but it has capacitive properties. When switching between the transparent and opaque states of the PDLC layer, the change in capacitance can be used for energy recovery. The recovered energy can be directly used for the switching operation of the PDLC layer, reducing dependence on external power supply, improving the energy efficiency of electronic devices, and reducing the overall power consumption of the device.
[0036] In some embodiments, a dynamic balance between privacy protection and display can be achieved through a composite structure of the atomizing layer 1021 and the light-transmitting layer 1022. The continuously adjustable nature of the light-transmitting layer 1022 allows sensitive information to be locally enhanced by atomization, while maintaining high light transmittance for non-sensitive information, avoiding the impact of full-screen atomization on information display and reducing display efficiency loss. The dual-layer structure, combined with zoned driving technology, allows the privacy protection area to dynamically expand with the viewing angle, improving the accuracy of privacy protection. In a specific embodiment, the atomizing layer 1021 and the light-transmitting layer 1022 are each equipped with independent driving circuits for privacy protection. The PDLC layer achieves rapid atomization under 24V AC drive, or the EC layer adjusts its light transmittance within the range of 5%-90% by controlling it with 1.5V DC.
[0037] Please see Figure 3 , Figure 3 This is a schematic diagram of another embodiment of the electronic device of this application.
[0038] In one optional implementation, the identification module 101 includes a viewing angle identification module 1011 and an information identification module 1012. The viewing angle identification module 1011 is used to obtain the viewer's image information and / or distance information to obtain the viewing angle information. The information identification module 1012 is used to identify the privacy level of the display information of each display area and transmit the identification of the display area and the privacy level to the display screen 102.
[0039] The recognition module 101 includes a view recognition module 1011 and an information recognition module 1012.
[0040] The viewing angle recognition module 1011 acquires viewing angle information through image and distance information. This information can be obtained using a combination of a near-infrared camera and a ToF depth sensor. A low-power infrared proximity sensor is used for constant-on detection, continuously monitoring a preset area in front of the screen, such as 0-50 cm or 0-80 cm, to check for any approaching objects. The infrared proximity sensor has extremely low power consumption, enabling all-weather monitoring with minimal impact on the device's overall battery life. When an object is detected entering the monitoring area, an advanced viewing angle recognition sensor is activated for further judgment. Upon receiving a wake-up signal from the primary viewing angle recognition sensor, the system activates the advanced sensor, such as a binocular IR camera or a ToF sensor, for detection. High-precision depth detection accurately calculates the absolute distance between the object and the screen, determining whether it is within the effective usage distance. Scene analysis is also performed, identifying a single user face facing the screen, multiple faces, or abnormal situations such as long-distance peeping. If a peeping situation is detected, a privacy protection scenario is triggered, and the module shuts down to return to a low-power state, awaiting the next wake-up by the primary viewing angle recognition sensor.
[0041] In one specific embodiment, the sensor structure of the near-infrared camera and the ToF depth sensor includes using a Sony IMX290 sensor with an 850nm infrared fill light to determine the viewing angle, or using an ams TSL25911 ambient light sensor to collect distance data.
[0042] The information recognition module 1012 analyzes the privacy level of the displayed content through algorithms. It can use the YOLOv5 object detection model to perform semantic recognition of screen interface elements, or use a lightweight CNN model to determine the type of sensitive information.
[0043] In some embodiments, the privacy level of displayed information can be divided into core privacy information and indirect privacy information. Core privacy information refers to information that would immediately and directly harm privacy if spied upon, mainly including authentication credentials such as passwords and verification codes, financial data such as bank card details and account balances, and confidential documents or private communications being viewed, requiring a high level of real-time protection. Indirect privacy information refers to information whose harm is not obvious in a single disclosure, but which will reveal user behavior, social relationships, or potential thoughts after long-term exposure or information aggregation. Examples include notification previews, application information, web pages, document or email titles, etc. The focus of protection is to prevent bystanders from causing derivative privacy risks through continuous spying. In addition, information such as operating system interfaces, wallpapers, default program icons, menu layouts, purely media and entertainment content, public and unrelated information, general system status, and blank interfaces can be considered as publicly displayed information. While ensuring device usability, lower levels of spying protection or no spying protection should be selected.
[0044] The information recognition module 1012 processes the display area identifier and privacy level information and sends them to the processor responsible for controlling the display screen 102 for privacy protection via privacy protection parameters. When a privacy protection scenario is triggered, the display screen 102 can dynamically adjust the light transmittance of the corresponding display area or trigger local fogging based on the recognition result.
[0045] Through the collaborative operation of the viewing angle recognition module 1011 and the information recognition module 1012, differentiated privacy protection can be achieved for different displayed content. When sensitive information is detected, the display screen 102 can automatically perform localized fogging on a specific area, ensuring privacy and security without affecting the visibility of other information. Combined with multimodal sensor data fusion, the probability of false triggering can be effectively reduced, and the response speed of privacy protection can be improved. This helps the display screen 102 to dynamically adjust the light transmittance and fogging degree of the display area, balancing privacy protection effectiveness and display clarity.
[0046] Please see Figure 4 , Figure 4 This is a schematic diagram of another embodiment of the electronic device of this application.
[0047] The identification module 101 further includes a permission identification module 1013, which is used to obtain the viewer's vital sign information, identify and determine the permission to turn off privacy protection; and / or, the permission identification module 1013 is coupled to the viewpoint identification module 1011, and is used to obtain the viewer's image information, identify and determine the permission to turn off privacy protection.
[0048] Vital signs information can include biological characteristics such as iris texture, facial contours, pulse information, etc.
[0049] In a specific embodiment, the image information can come from image data captured by a near-infrared camera or a ToF depth sensor, or a Sony IMX290 near-infrared camera combined with an 850nm infrared fill light can be used to collect vascular images to complete liveness detection. When the permission recognition module 1013 is coupled with the viewing angle recognition module 1011, it can make a comprehensive judgment by combining the viewer's viewing angle and image features. In response to the user's need to turn off privacy protection, permission recognition is triggered. At this time, by detecting that the viewer is looking at the screen and has passed dual biometric verification, such as iris recognition and facial recognition, or vascular liveness verification and facial recognition, the viewer is determined to be a user with permission verification, and privacy protection can be turned off to meet the user's needs for sharing display information.
[0050] In other implementations, the device pose can be detected by a six-axis inertial measurement sensor, or interactive information can be detected by crown interaction or screen touch interaction gestures. Alternatively, user authorization verification can be performed by combining preset gestures with facial recognition.
[0051] In other implementations, privacy protection can also be automatically turned off when the user closes the display interface that requires privacy protection and the display screen 102 no longer displays any privacy information that needs protection.
[0052] Multimodal verification combining vital sign and image information effectively prevents unauthorized users from bypassing privacy protections through photos, videos, or spoofing. The collaborative work of permission recognition and viewpoint detection enables rapid authorization closure, achieving financial-grade privacy protection.
[0053] In one embodiment, the identification module 101 includes an interaction identification module 1014 for device pose interaction information; and / or, the interaction identification module 1014 is coupled to the display screen 102 for acquiring touch gesture interaction information; the interaction identification module 1014 is also used to identify and determine anti-peeping interaction signals based on the acquired interaction information and transmit them to the display screen 102 for privacy protection.
[0054] The interactive recognition module 1014 can use a near-infrared camera to capture the user's arm movement trajectory, combine it with a six-axis inertial measurement sensor to detect changes in the position or posture of the wrist or arm, or sense the user's finger operations through a capacitive touch array on the screen or crown.
[0055] In some embodiments, the fogging level is increased when it is detected that a user is frequently viewing sensitive information, while a lower protection level is maintained in normal use scenarios to preserve the display effect.
[0056] When a user makes a preset gesture, the interaction recognition module 1014 can parse the interaction information and match it with pre-stored privacy protection instructions to generate a corresponding interaction trigger protection signal to enable or disable privacy protection. Multiple recognition methods can be deployed simultaneously; for example, infrared recognition can be automatically enabled when the user's arm is detected near the screen, while capacitive sensing mode can be switched when the user performs a touch operation. In other implementations, the screen protection area can be selected using touch gesture interaction information for personalized or precise privacy protection.
[0057] The interactive recognition module 1014 can significantly improve the trigger accuracy of privacy protection, avoid the problem of protection failure or over-protection caused by misjudgment by a single sensor. Combined with the visual recognition module 101 and the reality information recognition module 101, it can automatically adjust the protection strength according to the user's operating habits, effectively solving the problem of decreased user experience caused by fixed protection strength in traditional anti-spy schemes. At the same time, it reduces the probability of false triggering through accurate gesture analysis, making the privacy protection function both reliable and imperceptible.
[0058] A second aspect of this application also provides a privacy protection method for an electronic device 100, please refer to [link / reference]. Figure 5 , Figure 5 This is a flowchart of one implementation step of the privacy protection method for electronic devices in this application.
[0059] The electronic device 100 includes an identification module 101 and a display screen 102. The identification module 101 is used to identify viewing angle information and display information, and to detect the display scene. The display screen 102 is coupled to the identification module 101 and is used to display information. The recognition module 101 may include various sensors and a coupled processor. The sensors used to recognize viewpoint information may be one or more sensors such as a camera, infrared camera, depth sensor, and light sensor, which acquire information and then perform recognition through the processor. The display information used for recognition may be acquired through a program and interface running within the processor of the electronic device 100, by acquiring the interface control structure and data, or by using auxiliary functions such as screen reading, screen recording, or text recognition.
[0060] The privacy protection layer on the surface of the display screen 102 can be a frosted layer 1021 with a fogging effect, such as a PDLC layer, or a light-transmitting layer 1022 that changes light transmittance, such as an EC layer. Alternatively, a combination of the frosted layer 1021 and the light-transmitting layer 1022 can be used for privacy protection. A composite display structure is employed to dynamically adjust the privacy protection area, achieving both global protection and detailed protection of specific areas. The privacy protection methods include: S101: The recognition module 101 recognizes that the viewing angle information does not meet the preset safe viewing angle range, triggering a privacy protection scenario.
[0061] The preset security range can be set based on the user's line of sight at 0° when their eyes are directly facing the center of the screen, and shifted 30 to 45 degrees to the left or right. The specific preset security range can be determined based on factors such as the level of privacy protection and the screen size.
[0062] In other embodiments, when a privacy protection scenario is triggered, the display screen 102 may also pop up a window to prompt the user to enable privacy protection or adjust the viewing environment.
[0063] S102: In response to triggering a privacy protection scenario, the display information is identified by the identification module 101, and privacy protection parameters are transmitted to the display screen 102.
[0064] Privacy protection parameters may include instructions or configuration data used to control the display screen 102 to perform privacy protection, such as display information area identifier, privacy level, light transmittance, haze value, driving voltage, driving waveform parameters, and display switching sequence.
[0065] S103: Display screen 102 performs privacy protection for the corresponding display information area based on privacy protection parameters.
[0066] The display screen 102 performs display processing such as fogging, reducing light transmittance, and color changing in the display area containing privacy information according to privacy protection parameters, ensuring that viewers can view normally from a direct viewing angle and effectively preventing onlookers from peeping from viewing angles outside the preset safe range.
[0067] In one optional implementation, the identification module 101 includes a viewpoint identification module 1011 and an information identification module 1012; the viewpoint identification module 1011 and the information identification module 1012 are coupled together, and can communicate with the information identification module 1012 in a timely manner when the viewpoint identifies a privacy protection scenario.
[0068] The steps for triggering a privacy protection scenario by identifying that the viewing angle information does not meet the preset safe viewing angle range through the viewing angle recognition module 1011 include: obtaining the viewer's image information and / or distance information through the viewing angle recognition module 1011 to obtain the viewing angle.
[0069] The viewing angle recognition module 1011 may include a camera, an infrared camera, or a depth sensor, etc. It can acquire image information through the image sensor, use the visual algorithm running in the processor to locate key feature points of the eyeball or head in the image information, and obtain the viewer's viewing angle information by solving the spatial geometric relationship between the viewer and the screen normal, or by directly acquiring depth information through the depth sensor.
[0070] In some implementations, image and distance information can be acquired using a combination of a near-infrared camera and a ToF depth sensor. A low-power infrared proximity sensor is used for constant-on detection. When an object is detected entering the monitoring area, an advanced viewpoint recognition sensor is activated for further judgment, accurately calculating the absolute distance between the object and the screen to determine whether it is within the effective usage range. Scene analysis is also performed; if a spying state is detected, a privacy protection scenario is triggered, and the sensor shuts down to return to a low-power state, awaiting the next activation by the primary viewpoint recognition sensor.
[0071] The image information acquired by the view recognition module 1011 can also be shared with other modules of the electronic device 100 to reduce the number of image acquisitions, save resources, and improve battery life.
[0072] The steps of identifying display information through the identification module 101 and transmitting privacy protection parameters to the display screen 102 include: the information identification module 1012 identifies the privacy level of the display information in each display area and transmits the identifier and privacy level of the display area to the display screen 102.
[0073] In one optional implementation, the step of identifying display information and transmitting privacy protection parameters to the display screen 102 by the identification module 101 includes: determining the privacy protection parameters corresponding to the display area range that needs privacy protection based on the angle between the viewing angle information and the preset safe viewing angle by the identification module 101.
[0074] The privacy protection area can dynamically expand according to the viewing angle of the onlooker. In a specific embodiment, when the onlooker's viewpoint is turned to the side, for every 10° increase in the angle between the viewpoint information and the preset safe viewpoint, the display area that needs to be protected for privacy increases by 15%.
[0075] In one optional implementation, the step of the information identification module 1012 identifying the privacy level of the display information in each display area and transmitting the identifier and privacy level of the display area to the display screen 102 includes: identifying and determining the privacy protection parameters corresponding to the core privacy area containing core privacy information, the indirect privacy area displaying indirect privacy information, and the public display area not containing display information through the identification module 101.
[0076] In some embodiments, the privacy level of displayed information can be divided into core privacy information and indirect privacy information. Core privacy information refers to information that would immediately and directly harm privacy if spied upon, mainly including authentication credentials such as passwords and verification codes, financial data such as bank card details and account balances, and confidential documents or private communications being viewed, requiring a high level of real-time protection. Indirect privacy information refers to information whose harm is not obvious in a single disclosure, but which will reveal user behavior, social relationships, or potential thoughts after long-term exposure or information aggregation. Examples include notification previews, application information, web pages, document or email titles, etc. The focus of protection is to prevent bystanders from causing derivative privacy risks through continuous spying. In addition, information such as operating system interfaces, wallpapers, default program icons, menu layouts, purely media and entertainment content, public and unrelated information, general system status, and blank interfaces can be considered as publicly displayed information. While ensuring device usability, lower levels of spying protection or no spying protection should be selected.
[0077] The information recognition module 1012 processes the display area identifier and privacy level information and sends them to the processor responsible for controlling the display screen 102 for privacy protection via privacy protection parameters. When a privacy protection scenario is triggered, the display screen 102 can dynamically adjust the light transmittance of the corresponding display area or trigger local fogging based on the recognition result.
[0078] Please see Figure 6 , Figure 6 This is a flowchart of another embodiment of the privacy protection method for electronic devices according to this application. In some embodiments, the privacy protection method for electronic devices may include: S201: Obtain the viewer's image information and / or distance information through the viewpoint recognition module 1011 to obtain the viewing viewpoint.
[0079] S202: The view recognition module 1011 recognizes that the view information does not meet the preset safe view range, triggering a privacy protection scenario.
[0080] S203: The identification module 101 identifies and determines the identifiers and privacy protection parameters corresponding to the privacy levels of each display area, including the core privacy area containing core privacy information, the indirect privacy area displaying indirect privacy information, and the public display area excluding display information.
[0081] S204: The identification module 101 determines the privacy protection parameters corresponding to the display area range that needs privacy protection based on the angle between the viewing angle information and the preset safe viewing angle.
[0082] S205: Transmit privacy protection parameters to display screen 102.
[0083] S206: Display screen 102 performs privacy protection for the corresponding display information area based on privacy protection parameters.
[0084] By dynamically detecting the combined characteristics of the user's viewing angle and the displayed content, precise privacy protection can be achieved for different scenarios, avoiding the information access obstacles caused by full-screen fogging in traditional solutions. Employing a layered structure and independent zone control technology, the adjustment speed of privacy areas is improved to the 20-millisecond level, while maintaining the visibility of public information. A multimodal sensor fusion algorithm achieves viewing angle recognition accuracy of ±3 degrees, and zone control technology reduces the power consumption of the privacy protection mode to 40% of traditional solutions, significantly improving the smoothness of privacy protection display. This truly proactive, intelligent, precise, and adaptive privacy protection ultimately achieves a balance between privacy protection and user experience.
[0085] In one optional implementation, the recognition module 101 includes an interaction recognition module 1014 for acquiring device pose interaction information; and / or, the interaction recognition module 1014 is coupled to the display screen 102 for acquiring touch gesture interaction information; the privacy protection method includes: acquiring interaction information through the interaction recognition module 1014; triggering a privacy protection scenario in response to recognizing and determining that the interaction information satisfies a predetermined trigger gesture; and performing the steps of recognizing display information and transmitting privacy protection parameters to the display screen 102 in response to triggering the privacy protection scenario through the recognition module 101.
[0086] Vital information can include biometric features such as iris texture, facial contours, and pulse information. When the permission recognition module 1013 is coupled with the viewpoint recognition module 1011, it can make a comprehensive judgment by combining the viewer's viewing angle and image features. In response to the user's request to disable privacy protection, permission recognition is triggered. At this time, by detecting that the viewer is looking directly at the screen and has passed dual biometric verification, such as iris recognition and facial recognition, or vascular liveness verification and facial recognition, the viewer is determined to be a user with permission verification. Privacy protection can then be disabled, satisfying the user's needs for sharing display information.
[0087] The multi-factor authentication mechanism reduces the probability of unauthorized cracking, while the quick recovery function achieves a seamless transition from anti-spy triggering to recovery display. It also supports quick gestures such as pinching and flipping during movement, with a response latency of less than 50ms. Combined with the intelligent recognition module 101, privacy protection is enabled in real time, completely eliminating the cumbersome process of switching privacy protection modes.
[0088] In one optional embodiment, the display screen 102 includes a fogging layer 1021 and a light-transmitting layer 1022. The fogging layer 1021 is used for global fogging display, and the light-transmitting layer 1022 is used for global or local light transmission display of corresponding display information areas. The privacy protection method includes: the fogging layer 1021 adjusting the fogging degree according to privacy protection parameters, and the light-transmitting layer 1022 adjusting the light transmittance of the corresponding display area according to privacy protection parameters.
[0089] The screen is divided into multiple independent pixel units, each equipped with an independent driving circuit, supporting three modes: global fogging, local blurring, and light transmission enhancement, balancing privacy protection precision and display efficiency. The pixel unit area is determined based on the display screen area 102, control complexity, and privacy protection precision. In one embodiment, the area of a pixel unit on the smartphone screen is set to 0.5 × 0.5 mm.
[0090] In some embodiments, the atomization layer 1021 of the display screen 102 can be a PDLC layer or a light-transmitting layer 1022EC layer. A color display layer, such as an OLED or LCD screen, is also disposed at the bottom of the atomization layer 1021 and the light-transmitting layer 1022. The atomization layer 1021 and the light-transmitting layer 1022 act as dynamically adjustable filters to adjust the light emitted by the underlying display layer, thereby adjusting the display effect of the entire display screen 102.
[0091] In one specific embodiment, the atomizing layer 1021 and the light-transmitting layer 1022 are each equipped with independent driving circuits for privacy protection. The PDLC layer achieves rapid atomization under 24V AC drive, or the EC layer adjusts its transmittance within the range of 5%-90% by controlling the transmittance with 1.5V DC. The working states of the two layers are controlled separately by independent voltage sources. For example, in a payment scenario, the atomizing layer 1021 maintains a global atomization state, the light-transmitting layer 1022 performs a 0.5px Gaussian blur on the QR code area, while maintaining 85% transmittance in the time display area.
[0092] In one optional implementation, the privacy protection method includes: the identification module 101 acquires ambient light, generates and sends display adjustment parameters to the display screen 102 based on the brightness of the ambient light; the display screen 102 determines one of the display area range, display brightness and color temperature of the display screen 102 based on the adjustment parameters.
[0093] In some embodiments, L is set target =a·L ambient +b, where L target It refers to the display brightness, measured in nits (L). ambientAmbient light brightness, measured in lux, can be obtained in real time by setting an ambient light sensor in the recognition module 101. 'a' is a scaling factor that determines the sensitivity of the display brightness to changes in ambient light, and 'b' is an offset that ensures the screen still has a minimum safe brightness in a completely dark environment. In one specific embodiment, 'a' is 30 and 'b' is 50 nits.
[0094] When the ambient light brightness is detected to be less than a predetermined range, such as 50 lux, the electronic device 100 is considered to be in a low-light environment. The global display area of the display screen 102 shrinks from 100% to 60%, and the entire interface can be scaled down proportionally. In a specific embodiment, in a low-light environment, the display area of a smart wearable device shrinks from a diameter of 44 mm to a center of 22 mm, the local brightness is increased to 300 nits, and near-peeping protection is provided in a 3 mm area at the edge of the display area to form a privacy boundary, blocking peeping from a side view angle of 0°±45° directly facing the center of the screen.
[0095] The brightness adjustment of the display 102 covers a full range of lighting scenarios from 0.1 to 100,000 lux, and the color temperature dynamically matches the ambient light, achieving a blue light suppression rate of more than 40%. Continuous use reduces eye strain and significantly improves the user experience.
[0096] By leveraging the synergistic effect of ambient light sensing and parameter adjustment, the visibility of screen information under varying lighting conditions can be effectively improved, while simultaneously enhancing privacy protection. When ambient light intensity changes, the dynamic contraction or expansion of the display area reduces the visible range of a peeping angle. Combined with adaptive adjustments to brightness and color temperature, this ensures clear visibility for the wearer in strong light while avoiding overexposure in low-light environments. Compared to traditional static privacy solutions, this multi-dimensional display parameter adjustment mechanism reduces character recognition from a peeping angle to below 15%, while maintaining a constant character recognition time for viewers looking directly at the screen. In low-light environments, by contracting the display area and increasing local brightness, the power consumption of the privacy mode is reduced, significantly extending device battery life.
[0097] Unlike existing technologies, this application provides an electronic device, its manufacturing method, equipment, and charger. The electronic device achieves charging transmission by contacting an external power source through a spring assembly, making the contact position easy to align and ensuring a tight contact. By reusing the structure of the electronic device bracket and the vibration motor bracket, the structure is simple, ensuring the dustproof and waterproof requirements of the electronic device and improving the reliability and service life of the electronic device.
