Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light conversion substrates in display technology face interference issues between different light conversion bodies, limiting their suitability for high pixel density display panels due to manufacturing process constraints.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If different light conversion bodies are arranged on the same surface of the substrate, then the manufacturing process is simple, but the light conversion bodies interfere with each other and cannot be spaced closely
Solution Approach 1:
The patent transitions from arranging light conversion bodies on a single surface (2D arrangement) to arranging them on opposite surfaces of the substrate (3D arrangement with alternating patterns). This dimensional change allows first light conversion bodies on the first surface and second light conversion bodies on the second surface to be spaced closely without interfering with each other, as they occupy different spatial zones separated by the substrate thickness.
2Productivity
If the interval between different light conversion bodies is reduced to increase pixel density, then display resolution improves, but the manufacturing process becomes difficult to control
Solution Approach 1:
The patent segments the light conversion bodies into two distinct groups: first light conversion bodies arranged in first grooves on the first surface, and second light conversion bodies arranged in second grooves on the second surface. This segmentation allows each group to be manufactured and positioned independently, improving manufacturing controllability while enabling smaller intervals between adjacent different-type light conversion bodies on opposite surfaces, thereby increasing pixel density.
3Productivity
If light conversion bodies are arranged in alternating grooves on opposite surfaces, then interference between light conversion bodies is eliminated and pixel density increases, but the device structure becomes more complex
Solution Approach 1:
The patent combines multiple functions into the single substrate structure: the substrate serves as both the mounting platform for light conversion bodies and as a physical separator that prevents interference between bodies on opposite surfaces. The alternating groove patterns on both surfaces are integrated into one unified substrate design, allowing the increased pixel density and interference elimination benefits to be achieved without proportionally increasing overall device complexity.
