Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If liquid crystal display devices or organic light-emitting display devices are used to achieve high-definition large-screen displays, then display resolution and size can be improved, but device complexity and manufacturing cost increase significantly
Solution Approach 1:
The patent combines multiple light-emitting parts (first, second, and third light-emitting parts) into a single integrated semiconductor device structure. The wavelength conversion layers, partitions, and color filters are merged into one cohesive unit, eliminating the need for separate liquid crystal or organic light-emitting modules. This integration maintains high display resolution while significantly reducing overall device complexity and manufacturing cost.
2Manufacturing precision
If liquid crystal display devices or organic light-emitting display devices are used to achieve high-definition large-screen displays, then display resolution and size can be improved, but manufacturing cost increases significantly
Solution Approach 1:
The semiconductor device is segmented into distinct functional layers: light-emitting parts, wavelength conversion layers, partitions, and color filters. Each segment performs a specific function and can be manufactured independently using standardized semiconductor fabrication processes. This segmentation enables mass production through established techniques, significantly reducing manufacturing cost while maintaining high display resolution.
3Manufacturing precision
If partitions are placed between light-emitting parts to improve color purity, then color purity is improved, but light transmission efficiency may decrease
Solution Approach 1:
The partitions are designed with specific local properties: they are positioned only where needed between different color light-emitting parts, and their width is optimized to block stray light while minimizing impact on primary light transmission. The wavelength conversion layers are selectively applied to convert light wavelengths in specific regions, achieving high color purity without excessive light loss.
4Manufacturing precision
If the width between wavelength conversion layers is increased to improve color purity, then color purity is improved, but device area increases
Solution Approach 1:
The device structure employs asymmetric width design where the spacing between wavelength conversion layers is greater than the width of the light-emitting parts themselves. This asymmetric configuration allows sufficient separation for color purity while optimizing the overall footprint. The partitions provide additional asymmetric light blocking in critical areas, enabling compact device area without compromising color purity.
