Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic systems with multiple displays lack effective control over privacy filters, making it difficult to manage visibility of information on different screens independently and adapt to varying orientations and usage scenarios.
Innovation Solution
Implementing electronically controllable privacy filters on each display device, coupled with sensors to detect orientations and a control unit that adjusts opacity based on detected orientations and software applications, allowing individual control of privacy settings on each screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple displays are added to present more information, then information capacity is improved, but privacy control becomes more difficult
Solution Approach 1:
The patent applies segmentation by providing individual privacy filter control for each display device. Each display can independently activate or deactivate its privacy filter, allowing users to segment privacy control across multiple screens rather than treating them as a single unified system. This resolves the contradiction by maintaining high information capacity through multiple displays while simplifying privacy control through independent per-display management.
Solution Approach 2:
The patent implements dynamics by enabling real-time adjustment of privacy filter opacity based on detected orientations and usage scenarios. The system dynamically transitions between different privacy states (e.g., high opacity when laptop is closed, low opacity when open) allowing the privacy control mechanism to adapt to changing conditions. This resolves the contradiction by making privacy control flexible and context-aware rather than static, improving ease of operation while maintaining information capacity.
2Object-affected harmful factors
If static privacy filters are used on multiple displays, then privacy protection is improved, but flexibility and adaptability deteriorate
Solution Approach 1:
The patent transforms static privacy filters into dynamic components that can adjust opacity levels in real-time based on detected orientations and usage scenarios. The system transitions from fixed privacy protection to adaptive privacy control, allowing users to maintain privacy when needed while enjoying flexibility in display configuration. This resolves the contradiction by making privacy protection context-aware rather than rigid.
Solution Approach 2:
The patent applies parameter changes by modifying the opacity parameter of privacy filters based on detected orientations and software applications. Instead of using fixed opacity values, the system dynamically adjusts the optical parameter of privacy filters in response to changing conditions. This resolves the contradiction by enabling privacy protection to adapt to different usage scenarios through parameter modification rather than fixed configuration.
3Adaptability or versatility
If individual privacy filter control is implemented, then flexibility and adaptability are improved, but device complexity increases
Solution Approach 1:
The patent implements self-service by having the system automatically detect orientation and usage scenarios without requiring manual user input. The sensors and control unit work autonomously to determine when privacy filters should be activated or adjusted, reducing the burden on users while maintaining flexibility. This resolves the contradiction by enabling individual control flexibility through automated detection rather than complex manual control interfaces.
Solution Approach 2:
The patent applies feedback by using sensors to detect orientation and usage scenarios, then using this information to automatically adjust privacy filter opacity. The system creates a closed-loop control mechanism where detection information feeds back into the privacy control decision-making process. This resolves the contradiction by simplifying the control mechanism through automated feedback-based control rather than requiring complex user input and processing systems.

AI summary
An electronic system and method detect orientations of display devices of an electronic system, and determine an orientation mode of the display devices. The system and method identify one or more software applications presenting information on at least one of the display devices. Electronically controlled privacy filters in the display devices are individually activated or deactivated in the at least one of the display devices to alter opacity of the displayed information based on one or more of the orientations of the display devices and/or the one or more software applications.
