Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional micro display modules with X-cube prisms suffer from a lack of compactness and high light transmission efficiency due to the space required for cages to support display panels and potential optical losses during light transmission.
Innovation Solution
The micro display module integrates at least two micro-LED display panels directly adhered to the surfaces of an X-cube prism, eliminating the need for a cage and enhancing light transmission by minimizing space between the panels and the prism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a cage is used to support the X-cube prism and micro display panels, then the structural stability is improved, but the device volume increases and light transmission efficiency decreases
Solution Approach 1:
The support function is merged into the X-cube prism structure itself. The prism is designed with integrated support surfaces and positioning features that directly hold the micro-LED display panels, eliminating the need for a separate cage structure. This integration reduces the overall device volume while maintaining structural stability through the unified design.
Solution Approach 2:
The cage structure is extracted and removed from the system. By taking out the separate support cage and replacing it with integrated support features on the X-cube prism, the design eliminates unnecessary components that occupy space and interfere with light transmission, achieving a more compact and efficient structure.
2Manufacturing precision
If a cage is used to support the micro display panels, then the positioning accuracy is improved, but the light transmission efficiency deteriorates due to potential optical losses
Solution Approach 1:
The positioning function is merged into the X-cube prism structure. The prism includes integrated positioning surfaces and alignment features that directly contact and position the micro-LED display panels, eliminating the need for a separate cage. This integration ensures accurate positioning while providing direct optical pathways without intermediate structures that could cause light loss.
Solution Approach 2:
The cage structure is removed from the system. By extracting the separate support and positioning cage, the design eliminates potential optical obstructions and reflection surfaces that could cause light transmission losses, while the integrated prism structure maintains positioning accuracy through its built-in alignment features.
3Ease of manufacture
If space is provided between the micro display panels and X-cube prism, then the assembly ease is improved, but the light transmission efficiency decreases
Solution Approach 1:
The alignment and positioning functions are merged into the X-cube prism structure itself. The prism includes integrated alignment features, positioning surfaces, and mounting structures that guide and secure the micro-LED display panels in precise positions. This integration eliminates the need for separate alignment tools or complex assembly procedures, making the manufacturing process easier while ensuring optimal light transmission through direct contact.
4Loss of energy
If the micro-LED display panels are adhered directly to the X-cube prism, then the light transmission efficiency is improved, but the device complexity increases
Solution Approach 1:
The support, positioning, and optical transmission functions are merged into a unified X-cube prism structure. The prism is designed with integrated features that combine structural support, precise alignment, and optical pathways into a single component. This integration simplifies the overall device architecture by eliminating separate cages and alignment mechanisms, reducing structural complexity while maximizing light transmission efficiency through direct panel-to-prism contact.
