Innovation Solution
A three-dimensional display device comprising first and second display modules, each including a display light source, retroreflective component, and light splitting component, where the components are abutted end-to-end, forming first and second floating images that partially overlap, creating a trompe l'oeil effect for a three-dimensional image when viewed by human eyes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If current 3D display technologies are used, then three-dimensional display function is achieved, but display effect quality is insufficient
Solution Approach 1:
The display system is divided into multiple independent display modules (first display module with first display panel, second display module with second display panel). Each module generates its own floating image, and the images are then fused together. This segmentation allows each module to be optimized independently while achieving superior overall display效果 through image fusion.
Solution Approach 2:
Multiple floating images from different display modules are merged/fused together to form a comprehensive three-dimensional display effect. The light splitting components and retroreflective components combine light paths from multiple sources, creating overlapping floating images that enhance the overall 3D display quality and performance.
2Manufacturing precision
If multiple display modules are used to improve display quality, then display effect is enhanced, but device structure becomes more complex
Solution Approach 1:
The system is segmented into modular display units, each containing a display panel, light splitting component, and retroreflective component. This modular segmentation makes the complex system easier to manufacture, assemble, and maintain, as each module can be produced independently and then integrated.
Solution Approach 2:
The components are arranged in a nested configuration where display panels are positioned at ends of light splitting components, which are in turn positioned at ends of retroreflective components. This nested arrangement optimizes space utilization and reduces overall device complexity while maintaining multiple display modules.
3Manufacturing precision
If floating images are made to overlap to create 3D effect, then three-dimensional display quality is improved, but alignment precision requirements increase
Solution Approach 1:
The nested arrangement of display panels, light splitting components, and retroreflective components ensures that floating images are naturally positioned to overlap at the correct locations. The geometric relationships established by the nested structure facilitate precise alignment without requiring additional complex positioning mechanisms.
Solution Approach 2:
The light splitting components are configured with asymmetric angle relationships (first angle between first light splitting component and first retroreflective component, second angle between second light splitting component and second retroreflective component). This asymmetric configuration allows flexible control of light paths and floating image positions, enabling precise alignment while accommodating manufacturing tolerances.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device realizes high-quality three-dimensional displays through the fusion of partially overlapping floating images, enhancing the display effect by utilizing different visual distances and color depths or brightness.
Implementation Method 1
a first retroreflective component... a second retroreflective component... display light emitted by the first display light source exits the first light splitting component and forms a first floating image; and display light emitted by the second display light source exits the second light splitting component and forms a second floating image
Implementation Method 2
a first light splitting component... a second light splitting component... display light emitted by the first display light source exits the first light splitting component and forms a first floating image; and display light emitted by the second display light source exits the second light splitting component and forms a second floating image

AI summary
A three-dimensional display device includes a first display module to form a first floating image and a second display module to form a second floating image, and the first floating image and the second floating image partially overlap. A trompe l'oeil effect of the first floating image and the second floating image being fused to form a three-dimensional image is generated when viewed by human eyes, and three-dimensional displays can be realized.
