EMISSIVE ARTICLE WITH LIGHT EXTRACTION FILM |
| 摘要 |
An emissive article includes an OLED having a light emission surface, a circular polarizer, and a light extraction film optically between the OLED and the circular polarizer and being optically coupled to the light emission surface. The light extraction film includes a two-dimensional structured layer of extraction elements having a first index of refraction and a pitch in a range from 400 to 800 nm and a backfill layer including a material having a second index of refraction different from the first index of refraction. |

1. An emissive article comprising:
an OLED having a light emission surface; a circular polarizer; and a light extraction film optically between the OLED and the circular polarizer and being optically coupled to the light emission surface, the light extraction film comprising:
a structured layer of two-dimensional extraction elements having a first index of refraction and a pitch in a range from 400 to 800 nm;a backfill layer comprising a material having a second index of refraction different from the first index of refraction, wherein the backfill layer forms a planarizing layer over the extraction elements. |
