Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional manufacturing methods are used for light-emitting devices, then the manufacturing process is relatively simple, but the pixel density is low
Solution Approach 1:
The manufacturing process is divided into distinct stages: forming pixelated template with convex and concave portions, transferring two-dimensional material to the template, selectively removing material from concave portions, and integrating into light-emitting device structure. This segmentation enables high pixel density while managing process complexity through systematic breakdown of steps.
Solution Approach 2:
The patent utilizes two-dimensional material (such as exfoliated Ruddlesden-Popper perovskite single crystal layers) and transfers it to a three-dimensional pixelated template structure. This dimensional transition enables high-density pixel arrays by leveraging the atomic-layer properties of 2D materials conformally covering the template's convex and concave surfaces.
2Manufacturing precision
If high pixel density is achieved through conventional methods, then manufacturing complexity increases significantly, but the patent achieves high pixel density with manageable complexity
Solution Approach 1:
A pixelated template with predefined convex and concave portions is prepared in advance before material transfer. This preliminary structuring of the substrate enables subsequent high-precision material deposition and selective removal processes to achieve high pixel density without proportionally increasing manufacturing difficulty.
Solution Approach 2:
The pixelated template serves as an intermediary structure that facilitates the transfer of two-dimensional material into high-density pixel arrays. The template's convex and concave portions act as a mediator that guides material deposition and enables selective removal, simplifying the overall manufacturing process while achieving high precision.
