Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a light conversion layer is added to Micro-LED to achieve color display, then colorization requirement is met, but light intensity distribution becomes uneven
Solution Approach 1:
The patent applies local quality by creating concave-convex structures at specific locations within the light conversion layer. These localized structural variations cause different regions to scatter light differently, with convex portions directing light in certain directions and concave portions in others, thereby achieving uniform overall light distribution while maintaining color conversion functionality
Solution Approach 2:
The patent utilizes curved surfaces through the concave-convex structure design. The rounded convex and concave portions effectively scatter light by multiple reflections and refractions at curved interfaces, preventing direct light transmission and achieving uniform light intensity distribution across the display surface
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 solution enables uniform light intensity distribution, ensuring improved display effects by converting light in a different wavelength range and diffusing it through the concave-convex structure layers, meeting full-color display requirements.
Implementation Method 1
the color conversion layers are located within at least a portion of the through holes and capable of emitting a light in a wavelength range different than that of an incident light
Implementation Method 2
the concave-convex structure layers are arranged at least correspondingly in each of the through holes accommodating the color conversion layers, and each concave-convex structure layer is located on a light incident side of the light conversion layer and has a concave-convex structure surface facing towards the respective color conversion layer
