研究目的
To implement the UHD or higher-resolution displays, specially designed and fabricated FMM should be developed.
研究成果
The Invar slimming and the state-of-the-art laser ablation process open the door for UHD and higher-resolution FMM production. It is expected that with our high-resolution FMM sticks, display makers can produce UHD or higher-resolution AMOLED displays for mobile and AR application in the near future.
研究不足
The conventional rolled Invar FMMs with wet etching process have reached the technical limit, and the quality degrades significantly when the film thickness is decreased.
1：Experimental Design and Method Selection:
The study focuses on developing thin Invar foil and thermal damage-free laser ablation process for high-resolution FMMs.
2：Sample Selection and Data Sources:
Uses Invar foil for FMM sticks, with thickness reduced from 20 μm to 12 μm for UHD applications.
3：List of Experimental Equipment and Materials:
Includes femtosecond ultra-short pulse laser (USPL), electron backscatter diffraction (EBSD), and X-ray diffraction (XRD) for material analysis.
4：Experimental Procedures and Operational Workflow:
Describes the TCP method for Invar slimming and laser patterning process for fine pattern creation.
5：Data Analysis Methods:
Utilizes EBSD and XRD for analyzing material properties and stress.
