Screen Fingerprint Sensor Touch Control for Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminals, especially large-screen devices, face inconvenience in quickly turning off the screen due to the difficulty in operating the power button, leading to inefficient power consumption management.
Innovation Solution
A screen control method utilizing a touchscreen and screen fingerprint sensor to detect biometric texture information, allowing users to turn off the screen by touching specific areas or using a body part with non-pre-enrolled texture information, considering touch position, area, duration, and moving track information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the power button is used to turn off the screen, then the screen can be turned off, but the operation is inconvenient for large-screen devices
Solution Approach 1:
The patent replaces the mechanical power button with a touchscreen-based solution. The screen fingerprint sensor detects touch operations and biometric texture information to trigger screen shutdown, eliminating the need for physical button pressing while maintaining reliable screen control functionality.
Solution Approach 2:
The touchscreen itself serves dual purposes: it functions as both the display interface and the control input mechanism. By detecting touch operations and biometric information directly on the screen surface, the system uses the screen's own capabilities to control its own state, eliminating dependency on separate physical buttons.
2Use of energy by moving object
If automatic locking duration is set to reduce power consumption, then battery life is extended, but the user cannot immediately turn off the screen when needed
Solution Approach 1:
The system provides dynamic screen control with multiple shutdown triggers. Users can choose between automatic locking for power saving during inactivity, or immediate manual shutdown by performing specific touch operations (such as sliding from the top edge or pressing with unrecognized biometric information), allowing flexible adaptation to different usage scenarios.
Solution Approach 2:
The system pre-configures multiple shutdown triggers that are ready to activate immediately when conditions are met. The top-edge sliding gesture and unrecognized biometric touch are pre-programmed as shutdown commands, so when the user performs these actions, the screen shuts down immediately without requiring additional processing or configuration steps.
3Adaptability or versatility
If screen fingerprint sensor is used to detect touch operations, then biometric texture information can be obtained, but the system complexity increases
Solution Approach 1:
The screen fingerprint sensor is integrated into the touchscreen to provide multiple functions: it detects general touch operations for interface interaction, identifies biometric texture information for authentication, and recognizes specific patterns (such as sliding from the top edge) for system control. This single component serves multiple purposes, reducing the need for separate sensors for each function.

AI summary
Embodiments of the present invention provide a screen control method and a terminal. The method is applied to a terminal that has a touchscreen and a screen fingerprint sensor. The method includes: when the touchscreen is in a lighted state, receiving, by the terminal, a first touch operation; obtaining, by the terminal, texture information and touch information of the first touch operation by using the touchscreen and the screen fingerprint sensor, where the texture information is skin texture information corresponding to the first touch operation, and the touch information includes at least one of a touch position and a touch area; and turning off, by the terminal, the touchscreen based on the texture information and the touch information. The embodiments of the present invention can improve convenience of turning off the screen.
