Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D displays have not gained widespread adoption due to design limitations, particularly in creating a convincing depth perception without cumbersome wearable devices like AR and VR, and there is a need for innovative modalities to integrate depth into built environments.
Innovation Solution
A deep surface liquid crystal display system comprising two transparent and one opaque LCD screens mounted on an adjustable aluminum frame, utilizing the gap between them to create a volumetric and stereoscopic effect without requiring anaglyph glasses, by playing multiple videos simultaneously or sequentially to enhance depth perception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional single-layer LCD screens are used, then the device structure is simple, but depth perception and volumetric display effects cannot be achieved
Solution Approach 1:
The patent transitions from a traditional single-layer 2D display to a multi-layer stacked configuration with spacing, creating a three-dimensional volumetric display structure. Multiple LCD layers are positioned at different depths along the z-axis, enabling true 3D spatial representation and depth perception without requiring complex wearable devices.
Solution Approach 2:
The display system is divided into multiple independent LCD layers, each capable of displaying separate content. This segmentation allows different video files to be played on different layers simultaneously, creating stereoscopic and volumetric effects through the spatial separation of display elements.
2Manufacturing precision
If AR or VR wearable devices are used to achieve depth perception, then volumetric display effect is improved, but device complexity and user comfort deteriorate
Solution Approach 1:
The patent extracts the depth perception function from complex wearable AR/VR devices and implements it through a standalone multi-layer display structure. By using multiple LCD layers with physical spacing, the system achieves volumetric display effects without requiring head-mounted displays, glasses, or other wearable components.
3Manufacturing precision
If multiple LCD layers are stacked with gap to create volumetric effect, then depth perception is improved, but device complexity increases
Solution Approach 1:
The multi-layer LCD structure serves multiple functions simultaneously: each layer displays independent content, the spacing between layers creates depth perception, and the stacked configuration enables both 2D and 3D display modes. This universal design achieves volumetric effects while maintaining operational simplicity through standardized LCD components.
