Touch-Sensitive Display Unlocking Method for Portable Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional unlocking methods for touch-sensitive electronic devices, such as pressing physical keys or inputting passwords, are inconvenient and time-consuming, failing to meet the design concept of touch-sensitive information products.
Innovation Solution
An unlocking method for touch-sensitive devices that displays unlocking images on unfixed or fixed points on the screen, allowing users to switch the interface to an unlocking state by detecting clicks on these points, either simultaneously or sequentially, using a touch-sensitive device with a user interface controlling unit, display driving unit, and sensing unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical keys or passwords are used for unlocking, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The patent replaces physical mechanical key presses with touch-sensitive display interactions. Users can unlock by touching specific patterns or areas on the touchscreen, eliminating the need for physical key combinations while maintaining security through software-based authentication mechanisms.
Solution Approach 2:
The patent introduces an intermediary unlocking interface between the locked state and full access. This intermediate state presents visual cues or patterns on the touchscreen that guide users through the unlocking process, making it more intuitive than direct password entry while still providing security verification.
2Reliability
If passwords are used for unlocking, then security is improved, but loss of time worsens
Solution Approach 1:
The patent implements preliminary recognition of user intent through partial pattern detection or biometric pre-validation. When a user begins interacting with the unlock interface, the system anticipates the unlocking action and prepares authentication verification in advance, reducing the actual time required to complete the unlocking process.
Solution Approach 2:
The patent allows users to skip certain authentication steps under specific conditions. For example, recognized users or devices in trusted states can bypass full password entry and proceed directly to biometric verification or instant unlock, significantly reducing unlocking time while maintaining appropriate security levels.
3Ease of manufacture
If physical keys are used for unlocking, then ease of manufacture is improved, but adaptability worsens
Solution Approach 1:
The patent makes the touchscreen serve multiple functions: it acts as both the display interface and the input interface for unlocking. The same touch-sensitive display used for showing information also detects touch patterns, gestures, and inputs for authentication, eliminating the need for separate physical keys and improving device adaptability across different form factors.

AI summary
An unlocking method for a portable electronic device, and a portable electronic device and a touch-sensitive device employing the unlocking method are provided. The portable electronic device has a touch-sensitive display, and a user interface is displayed on the touch-sensitive display. The unlocking method includes respectively displaying at least one unlocking image on at least one unfixed point of the touch-sensitive display when the user interface is in a user interface locking state and sensing a touch signal of the touch-sensitive display. The unlocking method further includes switching the user interface to a user interface unlocking state when at least one click corresponding to the at least one unfixed point is detected on the touch-sensitive display.
