Investigating the Impact of Dosage Factor on Scattering and Image Quality in Quantum-Dot Displays

This study explores the relationship between dosage factor (DoF) and scattering ratio (SR) in quantum-dot color conversion films (QDCF) for display technology. Quantum dots (QDs) enable color conversion but induce light scattering, impacting image quality. Using LightTools simulations, we identified...

description This study explores the relationship between dosage factor (DoF) and scattering ratio (SR) in quantum-dot color conversion films (QDCF) for display technology. Quantum dots (QDs) enable color conversion but induce light scattering, impacting image quality. Using LightTools simulations, we identified three phases: DoF < 0.2 (mm·wt%) focuses on color conversion, 0.2 < DoF < 1.6 (mm·wt%) shows a linear increase in scattering, and DoF > 1.6 (mm·wt%) leads to scattering saturation. The optimal DoF range is 0.25-0.35(mm·wt%), balancing effective color conversion with minimal scattering. This study provides a streamlined approach for designing QDCF displays while maintaining high image quality.
