Abstract
The disclosure relates to emissive displays and, in particular, to emissive displays that include a top surface () that has a diffusely reflective inactive surface () adjacent a diffusely reflective emissive surface (). The emissive display further includes a polarization selective antireflection film component () that includes a linear absorbing polarizer (), a reflective polarizer (), and a quarter-wave retarder (), and is positioned separated from the top surface. The disclosure also relates to issues arising from these antireflection film components, such as brightness efficiency loss and image degradation such as pixel blur. The enhanced antireflection stack performs well in commercial OLED displays, with a 20% or greater brightness gain, a 30% or greater ambient light reflectance gain and no visually apparent image degradation.
