Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic displays lack the ability to provide a three-dimensional effect and personalized content to multiple users simultaneously, as they are primarily designed for static or semi-static content and do not effectively utilize liquid crystals for dynamic and semi-static modes.
Innovation Solution
A display device incorporating a first display and multiple transparent displays made of Smectic A liquid crystals, which can produce slices of an image to create depth and varying content for different users by blocking, diffusing, or scattering light, allowing for dynamic and semi-static modes of operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If multiple transparent displays are used to produce image slices for three-dimensional effect, then depth perception and three-dimensional effect are improved, but device complexity increases
Solution Approach 1:
The image is divided into multiple slices displayed on separate transparent displays stacked in layers. Each transparent display shows a portion of the image at a different depth plane, creating a three-dimensional effect through light field generation. The segmentation of the image into depth slices allows multiple users to perceive different content based on their viewing angle and position.
Solution Approach 2:
Multiple transparent displays are stacked in a nested configuration where each display layer is positioned within the optical path of the others. The displays are arranged in a compact stacked structure that generates a light field, allowing the system to achieve three-dimensional effect while maintaining a space-efficient form factor.
2Adaptability or versatility
If transparent displays block or diffuse light to provide personalized content for multiple users, then user personalization and content differentiation are improved, but transparency and user interaction are worsened
Solution Approach 1:
The transparent displays dynamically adjust their light modulation properties based on user position and viewing angle. The system uses real-time detection of user locations to control which display layers block, diffuse, or transmit light to specific users, enabling personalized content delivery while maintaining overall system transparency for interaction.
Solution Approach 2:
Different regions of the transparent displays have different light modulation characteristics tailored to specific user positions. Each display layer selectively blocks, diffuses, or transmits light in specific angular ranges to deliver personalized content to individual users while allowing other regions to remain transparent for general interaction and visibility.
3Adaptability or versatility
If Smectic A liquid crystals are used in transparent displays, then light control capability and display versatility are improved, but manufacturing complexity increases
Solution Approach 1:
Smectic A liquid crystals are used to enable dynamic control of light properties including transparency, scattering, and diffusion states. The liquid crystal material allows electrical control of optical parameters, enabling the display to switch between different operational modes (transparent, scattering, diffusion) and provide versatile light field generation capabilities.
Solution Approach 2:
The transparent display combines Smectic A liquid crystals with transparent substrates and optical elements to create a composite structure. This composite material approach integrates the light-modulating properties of liquid crystals with the optical clarity of transparent materials, achieving both light control capability and display versatility while managing manufacturing complexity through integrated design.
