Transparent Display Visibility via Dynamic Content Repositioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transparent display apparatuses face challenges in improving visibility of information due to interference from objects visible through the transparent screen, leading to deteriorated visibility.
Innovation Solution
A transparent display apparatus that includes sensors to detect the positions of objects and users, and a controller to determine the transmissive area where the object is viewable by the user, adjusting the display information's position and attributes to avoid overlap and enhance visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a transparent display apparatus is used to display information, then the user can view both the displayed information and objects behind the display simultaneously, but the visibility of the displayed information deteriorates due to interference from background objects
Solution Approach 1:
The patent applies dynamics by making the display attributes (position, size, color, transparency) changeable and adaptive based on real-time detection of background objects and user viewing conditions. The controller dynamically adjusts display parameters to optimize information visibility while maintaining transparency functionality, resolving the contradiction between fixed transparency and variable visibility requirements.
Solution Approach 2:
The patent changes physical and visual parameters of the display including position, size, color, and transparency level of displayed information based on detected background objects and user position. By adjusting these parameters dynamically, the system maintains both transparency capability and information visibility, overcoming the contradiction between these two features.
2Device complexity
If the transparent display shows information in fixed positions, then the display structure is simple, but the information may overlap with background objects reducing visibility
Solution Approach 1:
The patent transforms the static display position into a dynamic one that automatically adjusts based on background object detection. The controller continuously monitors the environment and repositions displayed information to avoid overlapping with background objects, maintaining visibility without requiring complex manual intervention while resolving the contradiction between simplicity and effectiveness.
Solution Approach 2:
The patent implements a feedback mechanism where the display system detects background objects and user position, then uses this information to automatically adjust display parameters. This closed-loop control ensures information visibility is maintained while keeping the overall system relatively simple, addressing the contradiction between structural simplicity and functional effectiveness.
3Loss of information
If sensors and controllers are added to detect positions and adjust display attributes, then information visibility is improved, but the device complexity increases
Solution Approach 1:
The patent applies multi-functionality by designing the controller to perform multiple tasks: detecting user position, identifying background objects, determining optimal display parameters, and adjusting display output. By consolidating these functions into a single control unit rather than separate dedicated components for each function, the system improves information visibility while minimizing the increase in device complexity.
Solution Approach 2:
The patent enables the display system to automatically detect and adjust its own parameters based on environmental conditions and user position without external intervention. The system self-regulates display attributes to optimize visibility, reducing the need for additional complex control mechanisms and manual operation interfaces, thus improving visibility while keeping complexity manageable.
