Abstract
AbstractWe present a convenient and low‐cost method to fabricate large‐area polycarbonate AR nanostructures to improve the luminous intensity and image clarity of a commercial 2.0‐inch OLED display panel in bright condition. The polycarbonate AR nanostructures were nanoimprinted by the graded‐density nanoporous silicon template with nanoparticle‐catalyzed etching. After attaching on the display panel to reduce the light reflection on the substrate, the brightness enhancement and decrease of ambient light reflection were observed. Due to the enhancement of contrast ratio, the quality index of the Lena image test was improved from 0.85 to 0.92 under strong ambient illumination.
