Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices complicate user access to security-set information, requiring separate passwords or authentication procedures, making it difficult for users to clear security settings.
Innovation Solution
A display device with a touch-sensitive display unit, sensor unit, and processor that provides feedback indicating a security on state, detects continuous touch inputs for security off or maintenance, and obtains a fingerprint to clear or maintain the security state of selected information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional user interface is provided for clearing security, then security protection is maintained, but user access becomes difficult
Solution Approach 1:
The display device provides visual feedback by displaying an indicator (e.g., locked icon) when information is in a security-on state. This feedback mechanism allows users to immediately recognize the security state without complex authentication procedures, resolving the contradiction between maintaining security protection and ensuring ease of user access.
Solution Approach 2:
The system automatically detects the user's intent through touch input patterns (continuous touch for security off, intermittent touch for security maintenance) and automatically processes the security state change without requiring separate password input or authentication procedures. This self-service approach simplifies user access while maintaining security through automatic fingerprint verification.
2Reliability
If separate password input is required to clear security, then security is maintained, but operation complexity increases
Solution Approach 1:
The patent merges the security verification process with the existing touch interface by detecting touch patterns (continuous vs. intermittent) and automatically initiating appropriate security procedures. This combines multiple functions (security verification, authentication, and state management) into a unified touch-based workflow, reducing operation complexity while maintaining security through automatic fingerprint verification.
3Adaptability or versatility
If touch input duration is used to differentiate security off and maintenance inputs, then input differentiation is achieved, but detection precision requirements increase
Solution Approach 1:
The system dynamically adjusts its detection criteria based on the touch input pattern. By monitoring the temporal characteristics of touch input (continuous vs. intermittent contact over time), the system adapts its security response accordingly. This dynamic approach allows robust input differentiation while maintaining reasonable detection precision requirements through pattern recognition rather than exact timing measurements.

AI summary
A display device is disclosed. The display device comprising: a display unit; a sensor unit; a storage unit; and a processor configured to: provide feedback for indicating a security on state of selected first information when selection input for selecting the first information in the security on state is detected, when a security off input for clearing security is detected in response to the feedback, obtain the fingerprint using the display unit, and convert the first information in the security on state into a security off state when the obtained fingerprint is matched with a pre-stored fingerprint, when a security maintenance input for maintaining security is detected in response to the feedback, maintain the security on state of the first information.
