OLED Light Extraction with Roll-to-Roll Nanostructured Films

摘要

Improving light extraction for OLED devices will be pivotal for their acceptance into the marketplace. Incorporating nanostructures within the high refractive index regions of the OLED multi-layer stack results in an over two-fold improvement in light extraction efficiency. Such nanostructures were made using roll-to-roll fabrication processes. We will also discuss the performance characteristics of the nanostructures on color-angularity and blurring of high-resolution pixels.
