Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a conventional display panel structure is used, then the manufacturing process is simple, but the light emission is uneven
Solution Approach 1:
The patent applies composite materials by combining light diffusion material and light conversion material within the same light processing layer. This composite structure enables the layer to simultaneously perform both light diffusion and wavelength conversion functions, improving light emission uniformity without significantly increasing overall structural complexity
Solution Approach 2:
The patent merges the light diffusion function and light conversion function into a single light processing layer. By integrating both functionalities in one layer rather than using separate layers, the patent achieves uniform light emission while minimizing additional structural complexity
2Manufacturing precision
If light diffusion material and light conversion material are mixed in the light processing layer, then light conversion uniformity is improved, but material distribution control becomes more difficult
Solution Approach 1:
The patent applies parameter changes by carefully controlling the concentration ratios and particle size distributions of the light diffusion material and light conversion material. By optimizing these parameters, the patent achieves uniform light conversion while maintaining manufacturability through standard coating processes
