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 three phases: DoF < 0.2 (mm $\cdot $ wt%) focuses on color conversion, 0.2 < DoF < 1.6 (mm $\cdot $ wt%) shows a linear increase in scattering, and DoF > 1.6 (mm $\cdot $ wt%) leads to scattering saturation. The optimal DoF range is 0.25–0.35 (mm $\cdot $ wt%), balancing effective color conversion with minimal scattering. This study provides a streamlined approach for designing QDCF displays while maintaining high image quality.
