Description

Technical Field

[0001] This invention relates to the fields of mobile terminal lock screen interface optimization, always-on display (AOD) technology, intelligent sorting of multi-source heterogeneous data, low-power rendering on mobile terminals, human-computer interaction and privacy and security protection technology, specifically to a system and method adapted to Android and iOS smartphones that can realize multi-schedule layered display in the state of screen off and locked screen.

[0002] This invention is primarily applied to the optimization of native lock screen systems in smartphones, the development of third-party smart lock screen plugins, and lightweight management of mobile office schedules, falling within the core technology category of mobile terminal intelligent interaction optimization. It also relates to the technical field of mobile terminal biometric unlocking (fingerprint recognition, facial recognition) and lock screen interaction permission linkage control. Background Technology

[0003] With the widespread adoption of mobile smart devices, mobile phone calendars, meeting reminders, and birthday reminders have become core auxiliary functions in users' daily work and life. Currently, smartphone calendar management and schedule viewing methods have many inherent technical flaws, seriously affecting the user experience. Specific flaws are as follows: First, the process of viewing schedules is cumbersome. Current mobile phones lack a native schedule display function on the lock screen. Users must complete multiple operations—turning on the screen, unlocking the device, and opening the calendar or office app—to view schedules such as meetings, birthdays, and daily activities. This is extremely inefficient for quick, temporary viewing and cannot meet the needs of high-frequency, lightweight schedule viewing. Existing terminal unlocking methods include biometric unlocking such as in-display fingerprint, side fingerprint, and 2D / 3D face recognition, as well as traditional unlocking methods such as passwords and patterns. All unlocking operations trigger the granting of full system permissions, lacking a lightweight schedule interaction permission isolation mechanism between locking the screen and fully unlocking.

[0004] Second, the always-on display and lock screen interfaces have limited functionality. Current mobile phone Always-On Display (AOD) only supports the display of time, battery level, and basic notification icons, and does not support the display of structured and categorized schedule information; traditional desktop schedule widgets only become active on the desktop after unlocking, and the initial always-on display and lock screen interfaces have no schedule preview capability.

[0005] Third, the schedule data lacks intelligent hierarchical and organizational logic. Existing calendar systems simply arrange all schedules linearly by time, failing to automatically distinguish between urgent meetings, annual birthdays, daily activities, and long-term appointments. Important schedules are mixed with ordinary schedules, and there are no automatic top placement, weighted sorting, or conflict warning mechanisms. Users need to manually filter and organize them, resulting in extremely low levels of intelligence.

[0006] Fourth, OLED screen displays pose a risk of hardware damage. If a traditional fixed-image, off-screen display schedule is used, the long-term static pixel illumination can easily cause OLED screen burn-in and pixel aging. Currently, there is no mature dynamic anti-burn-in + low-power collaborative solution in the industry.

[0007] Fifth, there is a lack of schedule privacy protection mechanisms. Current lock screens lack schedule desensitization features, displaying complete schedule details on lock screens in public places, which easily leaks users' private life information and corporate office secrets, resulting in poor privacy and security. Furthermore, current biometric unlocking lacks a secondary schedule privacy control mechanism; all schedule data is displayed in full by default after unlocking, making it impossible to distinguish between lock screen-free viewing and tiered viewing permissions after biometric unlocking.

[0008] Sixth, poor compatibility of office data across multiple platforms. Currently, mobile calendars cannot automatically sync scheduled meeting data from mainstream office software such as DingTalk, Lark, WeChat Work, and Tencent Meeting. Work schedule data is fragmented and cannot be displayed in an integrated manner.

[0009] In summary, existing technologies lack a comprehensive lock screen calendar display solution that can integrate multi-source calendar data, intelligently hierarchical and graded, adapt to all screen models, balance low power consumption, screen protection, privacy and security, and quick interaction, and can also link biometric unlocking permissions to differentiate lock screen unlock-free interaction and fully unlock permission boundaries. Based on the gaps and deficiencies of the existing technologies, this invention proposes a novel technical solution. Summary of the Invention

[0010] Purpose of the invention The purpose of this invention is to overcome the technical defects of existing technologies, such as cumbersome operation of viewing mobile phone schedules, single display format, lack of intelligent hierarchical classification, easy screen damage, uncontrollable power consumption, poor privacy, lack of data interoperability across multiple platforms, and lack of isolation and control over biometric unlocking and screen lock interaction permissions. This invention provides a multi-schedule hierarchical display system and method for mobile phones with screen off / on / locked, enabling lightweight previewing of seven-day schedules, intelligent classification and hierarchical display, and quick operation without unlocking in the screen-off and locked states. It also achieves full model compatibility, low power consumption, OLED screen burn-in prevention, and schedule privacy desensitization protection. By linking fingerprint / face recognition unlock status to differentiate interaction permission levels, it significantly improves the convenience, security, and intelligence of mobile schedule management. Technical solution

[0011] To achieve the above objectives, the first aspect of this invention provides a multi-schedule layered display system for mobile phones with screen off / on and locked screens, comprising five core functional modules that work together: an underlying system adaptation module, a multi-source schedule intelligent sorting engine, a screen off / on dual-mode screen rendering module, a lock screen interaction control module, and a power consumption and privacy management module. These modules collaborate in layers and share data, achieving full automation of multi-source data synchronization, intelligent processing, visual rendering, human-computer interaction, and secure power consumption management. The five modules are linked to the terminal's biometric system, which uses fingerprint and facial recognition unlock status to divide access into three levels of permission domains, enabling hierarchical control of interactive operations and data display permissions.

[0012] The underlying system adaptation module serves as the data input terminal of this invention, used to interface with the underlying operating systems of both Android and iOS mobile phones. It obtains legitimate system permissions without requiring rooting or jailbreaking, enabling multi-terminal and multi-software data adaptation and real-time synchronization. The underlying system adaptation module also interfaces with the terminal's biometric identification interface, acquiring real-time information on the working status, unlock verification results, and permission authorization levels of the fingerprint and facial recognition modules, providing a permission benchmark for upper-layer interaction and privacy management.

[0013] For Android devices: It integrates with the system's native Always-On Display (AOD) framework, lock screen rendering interface, system calendar read / write permissions, and background persistent running permissions; it automatically captures system calendar schedules, contact birthdays, and birthday management information, while simultaneously synchronizing online meeting reservation data from DingTalk, Lark, WeChat Work, and Tencent Meeting in real time to build a complete raw schedule database. It also integrates with the Android biometrics framework BiometricPrompt interface to legally obtain unlocking status parameters for in-display fingerprint, side fingerprint, and facial recognition.

[0014] For iOS devices: It integrates with the phone's Standby framework, the underlying extension interface for lock screen widgets, and the system calendar cloud synchronization interface to synchronize system calendar, contacts, birthdays, birthday management, and schedule data from mainstream office software, ensuring the integrity of Apple device functionality. It also integrates with the iOS LocalAuthentication biometric framework to obtain authorization and unlocking status data for Face ID facial recognition and Touch ID fingerprint recognition.

[0015] This module continuously captures and updates all raw schedule data in real time, removes invalid and redundant data, and stably pushes it to the downstream multi-source intelligent schedule sorting engine. Simultaneously, it synchronizes biometric status data to the lock screen interaction control module and the power consumption and privacy management module in real time.

[0016] The multi-source schedule intelligent sorting engine is the core data processing unit of this invention. It is used to receive the raw schedule data transmitted by the underlying adaptation module, complete data cleaning, type identification, weight classification, conflict detection, cycle generation and countdown calculation, and output structured and hierarchical standard schedule data. It includes four functional sub-units: data classification and identification sub-unit, three-level weight classification sub-unit, schedule conflict detection sub-unit, and cycle schedule loop sub-unit.

[0017] Data classification and identification sub-unit: Through keyword matching, data tag recognition, and address book time matching algorithms, it automatically distinguishes between meeting schedules, birthday schedules, private events, all-day appointments, short trips, and starred important work schedules, and binds exclusive classification tags to different types of trips.

[0018] Three-level weighted hierarchical sub-units: A three-level display weight system is constructed according to the time dimension to realize intelligent sorting of schedules: The first level of the highlighted layer is all the schedules of the day, and the countdown reminders are implemented with gradient bolding at 24h, 2h, and 15min based on the approaching time of the meeting; the second level of the regular layer is the important schedules in the next 1-3 days; the third level of the collapsed layer is the schedules in the 4-7 days ahead, which are displayed in a folded and collapsed manner by default to reduce interface redundancy.

[0019] Schedule conflict detection subunit: Real-time comparison of time intervals of all trips, automatically marks items with multiple overlapping schedules within the same time period in red, generates conflict warning prompts, and helps users optimize their trip arrangements.

[0020] The recurring schedule cycle sub-unit automatically identifies recurring schedules such as annual birthdays, weekly meetings, and monthly fixed activities, and automatically generates schedule data in a loop, eliminating the need for users to repeatedly enter data and achieving long-term automatic schedule updates.

[0021] The dual-mode rendering module receives structured process data output by the sorting engine and adapts the rendering scheme according to the different hardware types of the mobile phone screen. It is divided into an OLED-specific always-on display mode and a universal on-screen pop-up mode, balancing display effect, power consumption, and screen security. The rendering logic is associated with the biometric recognition status. When the phone is not unlocked by fingerprint / face recognition, a lightweight desensitized / layered interface is rendered. After the phone is fully unlocked by biometric recognition, a full details interface is rendered.

[0022] OLED-exclusive Always-On Display (AOD) mode: Employs low-power monochrome local pixel illumination technology to render layered schedules, activating only the pixels required for display, significantly reducing standby power consumption; Equipped with a dynamic pixel random offset algorithm, it periodically fine-tunes the coordinates of text pixels, completely solving the burn-in and pixel aging problems caused by long-term fixed images on OLED screens; It also features a nighttime timed shutdown strategy, automatically turning off the always-on display schedule during preset nighttime periods, further reducing device power consumption.

[0023] Full-model screen-on pop-up mode: Adapted to all LCD and OLED smartphones. When the user presses the power button to turn on the screen or when the screen is locked, an independent semi-transparent schedule card is generated on top of the lock screen wallpaper. The schedule is displayed in three layers with different weights. The card will automatically fade and hide after 3 seconds by default. Users can also manually swipe down to hide the card without affecting the regular lock screen experience.

[0024] This module supports user-defined configuration parameters, including the number of days for trip display, font size, text color, card position, theme style, and trip category on / off switch. Birthday, work, and personal trip displays can be turned off individually to personalize the experience to meet user needs.

[0025] The lock screen interaction control module enables lightweight human-computer interaction in the locked screen state, breaking the traditional lock screen's limitation of only supporting unlocking and screen-on. Users can long-press on a schedule item on the lock screen to bring up a quick operation menu, supporting multiple operations such as schedule postponement, one-click reminders for attendees, itinerary navigation, and marking as completed. It also supports expanding / collapsed a seven-day advance itinerary list for quick access to the complete itinerary. All operations can be performed without unlocking the phone, greatly shortening the operation process. This module divides interaction permissions into three levels based on fingerprint / face recognition unlock status: 1) Screen-off silent state: no touch interaction, only static display; 2) Screen-on state without biometric unlock: only supports card collapsing and list expansion / collapse, prohibiting modification operations; 3) Unlock state authorized by fingerprint / face recognition: grants full permissions for schedule editing, push notifications, and navigation shortcuts, achieving precise permission isolation.

[0026] This module is the core of the security and power consumption control of this invention, comprising two major functional systems: intelligent power consumption management and privacy security protection. The privacy security protection system is linked to the biometric unlocking result to construct a three-level privacy display permission system: "lock screen authentication-biometric trust-full unlock".

[0027] Power consumption management system: Real-time statistics of additional power consumption during Always-On Display (AOD) are maintained, limiting daily power consumption increases to less than 5% to ensure normal battery life. The system dynamically adjusts the brightness of calendar text based on ambient light sensor data, automatically reducing brightness in low-light environments and adaptively increasing brightness in bright light environments, balancing display quality and power consumption. The power consumption management system also links to the wake-up frequency of the biometric module, reducing the additional power consumption caused by high-frequency wake-ups for fingerprint / face detection.

[0028] Privacy Management System: Features a built-in global privacy desensitization mode. When enabled, the lock screen only displays statistics for "Today's X Activities," completely hiding sensitive details such as activity time, content, and type. Users can individually block data from private, family, or work activities, adapting to privacy protection needs across various scenarios including office work, public transportation, and home. When the device fails to unlock using fingerprint / facial recognition, the desensitization display logic is forcibly loaded first; after biometric authentication is completed, the desensitization restriction is automatically lifted, displaying the complete activity details.

[0029] The method for displaying multiple schedule layers on a mobile phone screen-off / screen-on / locked screen according to the present invention includes the following complete execution steps: System initialization and permission configuration: Users can enable this function in the phone's system settings or plugin settings interface, complete the authorization of calendar, contacts, and third-party office software, complete the authorization of biometric permissions (read fingerprint / face unlock status), customize the schedule display cycle, privacy mode switch, interface visual style, automatic control parameters, and complete system initialization.

[0030] Multi-source data real-time synchronization and updates: The underlying system adaptation module continuously captures travel data from multiple platforms such as system calendar, address book birthdays, birthday manager, DingTalk, and Lark in the background, and synchronously collects the working status data of fingerprint recognition and face recognition modules in real time, updating the original travel database in real time to ensure data timeliness and integrity.

[0031] Intelligent sorting and structured processing: The multi-source intelligent schedule sorting engine cleans and classifies the raw data, sorts it hierarchically according to a three-level weight rule, completes schedule conflict detection, cycle schedule generation, meeting countdown calculation, and outputs standardized hierarchical schedule data.

[0032] Hardware recognition and dual-mode screen rendering: The system automatically identifies the phone screen hardware type. For OLED models, it renders both the always-on display and the pop-up window when the screen is on, while for LCD models, it only renders the pop-up window when the screen is on, thus completing the interface visualization. During the rendering process, the biometric unlock status is read simultaneously, and the corresponding level of process display style and data anonymization level are matched.

[0033] Lock screen interaction response processing: The system monitors user operations in real time and responds to interactive commands such as turning on the screen to view, long-pressing for quick operations, swiping down to collapse, and expanding long-term schedules. It combines the current fingerprint / face recognition authorization status to verify operation permissions, blocks highly sensitive editing operations in unauthorized states, and completes the corresponding function execution.

[0034] Dynamic power consumption and privacy control: The system automatically adjusts screen brightness, turns off always-on display, and hides trip details based on ambient light, time of day, and user privacy settings. It also optimizes power consumption allocation by linking biometric detection frequency to achieve all-weather intelligent management.

Figure 5 This is a schematic diagram of the interactive interface for displaying schedules in layers and differentiating permissions when the screen is locked, according to the present invention. Detailed description of the attached diagram: Figure 1 In this invention, five core modules are sequentially connected and interconnected. The underlying system adaptation module serves as the data input end, receiving multi-source data and transmitting it to the multi-source intelligent sorting engine for data processing. The processed structured data is then transmitted to the dual-mode rendering module for interface display. Simultaneously, it links with the lock screen interaction control module to achieve human-computer interaction. The power consumption and privacy management module regulates power consumption and protects privacy throughout the entire process, forming a closed-loop intelligent control system. The underlying system adaptation module additionally connects to the biometric identification subsystem, transmitting permission status data streams to the interaction and privacy modules.

Implementation

[0035] This invention provides two preferred implementation methods that are feasible to implement and adaptable to different models and application scenarios: The first method is the original factory pre-installed implementation: the entire system module is integrated into the underlying framework of the phone's operating system lock screen, and is factory-installed and fixed, with independent function switches in the system settings. This solution has a background memory usage of less than 80MB, no risk of background processes being killed, optimal power consumption control, adaptability, and stability, and is compatible with the latest flagship smartphones. It natively and deeply integrates with the system's biometric recognition underlying framework, with optimal permission isolation and power consumption linkage effects, and supports natively fixed control of three levels of interactive permissions.

[0036] The second approach is a third-party independent plugin implementation: A lightweight, standalone application is developed, implementing all core functions through a system lock screen widget and legitimate notification permissions. No underlying system modifications are required, making it compatible with older Android models and all iOS models. Only minor background operation limitations exist on some low-end devices, making it highly versatile. By granting read-only biometric permissions to the system to obtain the unlock status, hierarchical permission control is achieved without involving biometric data collection and storage, complying with privacy compliance requirements. Specific Implementation

[0037] Users can enable the schedule lock screen display function in the system settings of an Android OLED flagship phone, authorize access permissions for calendar, contacts, WeChat Work, and biometric status reading, set a seven-day itinerary display, and disable the privacy anonymization mode. The system automatically synchronizes three department meetings, two family members' birthdays, and four client appointments for the week.

[0038] The multi-source sorting engine highlights today's meetings and birthdays at the top, bolds and flashes meeting entries within 15 minutes and displays a countdown, detects no scheduling conflicts, and collapses customer appointments 4-7 days in advance to the bottom of the interface.

[0039] When the phone screen is off and in standby mode, AOD displays all schedules in a low-power, layered manner. The system fine-tunes the pixel coordinates of the text every 2 minutes to prevent screen burn-in. The screen-off schedule is automatically turned off from 11 PM to 7 AM the next day to reduce standby power consumption.

[0040] When a user presses the power button to turn on the screen, a semi-transparent schedule card automatically pops up on the lock screen, highlighting the upcoming meeting. At this time, the device does not perform fingerprint / face recognition unlocking; the system only allows card collapse and list viewing operations, blocking schedule modification commands. After the user completes the authorization verification via in-display fingerprint, they can send meeting reminders to all participating colleagues with one click without unlocking the desktop. After the operation is completed, the card can be collapsed by swiping, without affecting the normal use of the phone.

[0041] iPhone LCD models do not have a native Always-On Display (AOD) function; the system automatically adapts to retain only the on-screen pop-up display mode. After the user grants permissions to contacts, birthday management, Lark, and Face ID biometric reading permissions, the system automatically synchronizes annual family birthdays and online work meeting schedules, using different color blocks to distinguish between work and personal schedules.

[0042] Every time a user unlocks their phone, a calendar card automatically pops up for 3 seconds, displaying the day's and recent key events. When in public places, if the user enables privacy mode, the lock screen will only display the number of "2 events today," hiding all sensitive event details. After the user unlocks the phone using Face ID facial recognition, the system automatically removes global anonymization, displaying the complete event details and effectively protecting privacy.

[0043] This embodiment does not have an always-on display function, resulting in no additional standby power consumption. Background memory usage remains stable, preventing phone lag and excessive battery drain. It is compatible with older Apple models and runs stably. All biometric data is read only from status tags; no raw facial or fingerprint biometric information is stored, complying with mobile terminal privacy regulations. Beneficial effects

[0044] Compared with the prior art, the present invention has the following significant advantages: The S1 significantly improves operational efficiency: eliminating the cumbersome process of unlocking and opening the app, users can directly browse all important schedules for the past seven days even when the screen is off or locked, allowing for lightweight browsing and greatly improving schedule management efficiency.

[0045] S2 boasts a high level of intelligence: it enables automatic synchronization of multi-source data, intelligent classification, three-level weighted hierarchical sorting, conflict warning, and automatic generation of periodic schedules, eliminating the need for manual editing and organization by users, and significantly optimizing the intelligent experience.

[0046] S3 offers full-coverage compatibility across all models: differentiated adaptation for OLED and LCD screen models, enabling low-power always-on display with screen burn-in protection for OLED models, and providing a pop-up window mode for LCD models, compatible with all smartphones on the market.

[0047] S4 offers controllable privacy and security: It supports global privacy desensitization and categorized travel information blocking, and integrates fingerprint / facial recognition unlock status to manage data display permissions in a tiered manner. The display mode can be freely switched according to the scenario, effectively preventing the leakage of travel information in public places.

[0048] S5 unlock-free quick interaction: Enables quick operation of schedules even when the screen is locked. Based on biometric authorization level, operation permissions are differentiated, and one-click operation of multiple functions such as reminders, navigation, postponement, and marking is completed, shortening the usage process.

[0049] S6 is highly adaptable to various office scenarios: it integrates data from multiple sources, including the system calendar, address book, and mainstream office software, solving the problem of fragmented work schedule data and meeting the core needs of workplace users.

[0050] The S7 operates stably and consumes very little power: the pre-installed system version has extremely low resource consumption and controllable power consumption increments; third-party plugin versions have wide compatibility; biometric identification only reads the status and does not collect raw data, so there is no risk of privacy leakage and power consumption increments are controllable, which will not affect the phone's battery life and system smoothness, making it highly practical.
