Engineering Contradiction Analysis
1Manufacturing precision
If conventional display devices are used for VR/AR/SR/MR, then the device can be manufactured at current cost levels, but the resolution is insufficient and color reproducibility is poor
Solution Approach 1:
The display device is segmented into multiple light-emitting elements (first and second light-emitting elements) that emit different colors, with each element having its own pixel electrode and organic layer. This segmentation enables high-resolution display while maintaining manufacturing feasibility through modular construction
Solution Approach 2:
Different regions of the display device are assigned different functional qualities: the first light-emitting element emits one color while the second emits another color, with each region optimized for its specific function. The insulating layers and resin layers are strategically positioned to enhance local color accuracy and resolution
2Manufacturing precision
If the display device uses multiple light-emitting elements with different colors, then color reproducibility is improved, but the device structure becomes more complex
Solution Approach 1:
Multiple light-emitting elements emitting different colors are merged into a single integrated display structure sharing common electrodes and insulating layers. This combining approach achieves high color reproducibility while reducing overall structural complexity compared to separate display units
Solution Approach 2:
The common electrode and insulating layers serve multiple functions: they provide electrical connection for both first and second light-emitting elements, provide insulation for multiple organic layers, and maintain structural integrity across different color regions. This multi-functionality reduces the number of separate components needed
