研究目的
To propose a novel optical model for layer structure films to enable precise control of light diffusion angle range, incorporating the effects of refractive index differences and structural characteristics.
研究成果
The proposed DPGS model effectively incorporates structural characteristics (distorted interfaces and varying layer widths) into a phase grating framework, enabling precise control of light diffusion angle range. Key factors are the difference in refractive indices (ΔnHL) and layer width, with validation through simulation and experiment showing consistency. Future work could focus on refining the model for more complex structures and practical applications in display technology.
研究不足
The optical model may have simplifications compared to real film structures; simulations are based on specific assumptions (e.g., stepwise changes in layer width), and experimental variations (e.g., photo-initiator concentration effects) might not fully capture all complexities. Optimization for broader material sets or industrial scalability is not addressed.
1：Experimental Design and Method Selection:
The study used optical simulation based on the finite-difference time-domain (FDTD) method to construct and analyze models of layer structure films, including phase grating models and the proposed Distorted Phase Grating Stacking (DPGS) model.
2：Sample Selection and Data Sources:
Simulations were performed with varying parameters (e.g., grating spacing, refractive indices); experimental validation used fabricated films with different photo-initiator concentrations.
3：List of Experimental Equipment and Materials:
Optical simulation software (Poynting for Optics, Fujitsu Corporation), confocal laser microscope (VK-9700, KEYENCE Corporation), conoscope (AUTOPONIC-MELCHERS GMBH), collimated LED light source, Slice Master (JASCO Corporation), and materials like monomers (UX-6101, OPP-1 from Nippon Kayaku Co., Ltd.) and photo-initiator (2-hydroxy-2-methylpropiophenone from Tokyo Chemical Industry Co., Ltd.).
4：Experimental Procedures and Operational Workflow:
Simulations defined computational domains with specific boundary conditions and light sources; experiments involved fabricating films via UV polymerization, slicing them, imaging cross-sections, and measuring luminance vs. diffusion angle.
5：Data Analysis Methods:
Analyzed light diffusion distributions from simulations and experimental luminance data to compare with model predictions.
