“…From the SEM images, the particle diameter was measured to be 95.90 nm with a standard deviation of 5.88 nm, and the inter-particle distance was 12.49 nm 1.95 nm. Actually, such a nanoparticle monolayer can also exhibit an AR property [20][21][22][23][24]. In our experiment, we used it as an imprinting template to obtain a concave structure.…”

Sunlight readability is a critical requirement for display devices, especially for mobile displays. Anti-reflection (AR) films can greatly improve sunlight readability by reducing the surface reflection. In this work, we demonstrate a broadband moth-eye-like AR surface on a flexible substrate, intended for flexible display applications. The motheye-like nanostructure was fabricated by an imprinting process onto a flexible substrate with a thin hard-coating film. The proposed nanostructure exhibits excellent AR with luminous reflectance <0.23% and haze below 1% with indistinguishable image quality deterioration. A rigorous numerical model is developed to simulate and optimize the optical behaviors. Excellent agreement between the experiment and simulation is obtained. Meanwhile, the nanostructure shows robust mechanical characteristics (pencil hardness >3 H), which is favorable for touch panels. A small bending radius (8 mm) was also demonstrated, which makes the proposed nanostructure applicable for flexible displays. Additionally, a fluoroalkyl coating was applied onto the moth-eye-like surface to improve the hydrophobicity (with a water contact angle >100°). Such a self-cleaning feature helps protect touch panels from dust and fingerprints. The proposed moth-eye-like AR film is expected to find widespread applications for sunlight readable flexible and curved 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.
