Color Brightness of RGB Light Sources Covered by Anti-Reflective Nanoimprinted Films

摘要

Single-and double-sided imprinted anti-reflective (AR) films with conical nanopatterns were fabricated using an ultraviolet nanoimprint lithography process, and their anti-reflection performances are studied considering the effects of RGB display backlight. The effects of the fabricated AR films on the RGB color generated by reflection were evaluated to understand the contribution of backlight on anti-reflection performance. It was found that the fabricated double-sided imprinted AR film on PMMA exhibited anti-reflective performance with transmittance of 96.76% and reflectance of 0.55% at a wavelength of 550 nm. Additionally, the measurements on the target to background ratio of RGB pigments covered with the studied films showed that the detrimental effect of the double-sided imprinted film was smallest owing to the high transmittance and low reflectance of the double-sided nanopatterns.
