Transparent Display Transmittance Adjustment for Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional transparent screens lack adjustable transparency, leading to information leakage and compromised display effects when placed on intricate surfaces, as users can view content from various angles.
Innovation Solution
An electronic device with a display unit and an adjusting unit that switches between different transmittance states in response to command information, allowing for adjustable transparency to enhance display flexibility and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the transparent screen maintains high transmittance for viewing content from both sides, then users can view content from various angles, but information leakage occurs and display security is compromised
Solution Approach 1:
The patent applies a transmittance adjusting unit that enables the transparent screen to dynamically switch between different transmittance states. The screen can transition from a first transmittance state (allowing viewing from both sides) to a second transmittance state (preventing information leakage), resolving the contradiction between viewing convenience and information security through dynamic adaptability
2Device complexity
If the transparent screen has fixed transmittance, then the structure is simple, but display flexibility and user convenience are degraded
Solution Approach 1:
The patent introduces a transmittance adjusting unit with multiple transmittance states that can be switched based on different display needs. This dynamic adjustment capability provides versatile display flexibility while maintaining relatively simple structural integration, allowing the screen to adapt to various usage scenarios without significant structural complexity
3Adaptability or versatility
If the transparent screen is placed on an intricate surface, then the device can accommodate complex surface geometries, but the display effect is affected
Solution Approach 1:
The patent applies a transmittance adjusting unit that can locally control the optical properties of different regions of the transparent screen. By adjusting transmittance at specific locations or regions, the system can compensate for the effects of intricate surface geometries, ensuring consistent display quality across the entire screen area while maintaining compatibility with complex surfaces
