Light Shutter Panel for Transparent Display Clarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transparent display apparatuses often hinder video information recognition due to background scenes, degrading the primary function of providing video information.
Innovation Solution
A light shutter panel with a light blocking and light transmitting function, integrated into a transparent display apparatus, allowing users to select between transparent and non-transparent modes by adjusting the light transmittance ratio and blocking background light, ensuring video information clarity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a transparent display apparatus always provides a background scene, then the display can show both video information and background scene simultaneously, but the background scene hinders the observer from properly recognizing the video information
Solution Approach 1:
The patent applies the dynamics principle by making the light shutter panel switchable between transparent and opaque states. The shutter layer can be dynamically controlled to block or transmit light, allowing the display to adapt between transparent mode (showing background scene) and non-transparent mode (blocking background scene for better video information recognition). This dynamic control resolves the contradiction by enabling the system to change its state based on usage requirements.
2Loss of information
If a light shutter panel blocks all light from the back side, then video information clarity is improved, but the light transmittance ratio decreases
Solution Approach 1:
The patent applies the local quality principle by creating different regions within the light shutter panel with different light blocking characteristics. The first ink storage portion contains first black ink with specific optical properties, while the second ink storage portion contains second black ink with different optical properties. This allows selective light blocking in different areas, enabling the panel to block light where needed for video clarity while maintaining light transmission in other areas to preserve sufficient light transmittance ratio.
3Device complexity
If the light shutter panel uses a single ink storage portion, then the device complexity is reduced, but the ability to control light transmittance and blocking is insufficient
Solution Approach 1:
The patent applies the segmentation principle by dividing the ink storage portion into multiple separate portions - a first ink storage portion and a second ink storage portion. Each portion contains different black ink formulations with distinct optical properties. This segmentation allows independent control of light blocking and light transmission characteristics, providing enhanced adaptability for controlling light transmittance ratio while maintaining manageable device complexity through modular structure.
