40-4: Moth-eye Anti-reflection Surface for Sunlight Readable Flexible Displays

A broadband anti-reflection surface with moth-eye structure for sunlight readable flexible displays is demonstrated. The proposed nanostructure exhibits excellent anti-reflection performance (luminous reflectance 0.23%), low haze (0.95%), great flexibility (curve radius <8 mm), high hardness (>3H) and self-cleaning characteristics. A numerical model is developed to simulate and optimize the nanostructure. Excellent agreement between simulation and experiment is obtained.
