    Abstract: A multilayer optical film includes a plurality of polymeric layers arranged sequentially adjacent to each other. A difference in thickness between spaced apart first and second polymeric layers in the plurality of polymeric layers is less than about 10%. Each polymeric layer that is disposed between the first and second polymeric layers has a thickness less than about 400 nm. Each layer in a group of at least three polymeric layers in the plurality of polymeric layers that are disposed between the first and second polymeric layers has a thickness greater than an average thickness of the first and second polymeric layers by about 20% to about 500%. The group of at least three polymeric layers includes at least one pair of immediately adjacent polymeric layers.

    IPC: G02B5/30

    Abstract: Optical films, such as reflective polarizer films, and optical systems including the optical films are described. An optical system includes one or more optical lenses having at least one curved major surface, a partial reflector, and a reflective polarizer. For a substantially normally incident light in a predetermined wavelength range extending at least from about 450 nm to about 600 nm: the partial reflector has an average optical reflectance of at least 30%, and the reflective polarizer has an average optical reflectance Rs for a first polarization state, an average optical transmittance Tp for an orthogonal second polarization state, and an average optical reflectance Rp for the second polarization state, where Tp≥80%, Rp≤1%, and 50%≤Rs≤95%.

    Abstract: An optical system including a first optical element having a curved first major surface and an optical stack bonded and conforming to the curved first major surface of the first optical element is described. The optical stack includes a reflective polarizer substantially transmitting light having a first polarization state and substantially reflecting light having an orthogonal second polarization state and a non-adhesive flexible optical layer bonded to the reflective polarizer and comprising substantially parallel opposing first and second major surfaces. At least one location on the non-adhesive flexible optical layer has an optical retardance of less than about 100 nm or greater than about 200 nm at a wavelength of about 550 nm.

    Abstract: The disclosure relates to emissive displays and, in particular, to emissive displays that include a top surface (111) that has a diffusely reflective inactive surface (116) adjacent a diffusely reflective emissive surface (114). The emissive display further includes a polarization selective antireflection film component (120) that includes a linear absorbing polarizer (126), a reflective polarizer (124), and a quarter-wave retarder (122), 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.

    Abstract translation: 本公开涉及发射显示器，特别是涉及包括邻近漫反射发射表面（114）的具有漫反射不活泼表面（116）的顶表面（111）的发射显示器。 发射显示器还包括偏振选择性抗反射膜部件（120），其包括线性吸收偏振器（126），反射偏振器（124）和四分之一波长延迟器（122），并且与顶表面分离定位。 本公开还涉及由这些抗反射膜组件产生的问题，例如亮度效率损失和图像劣化，例如像素模糊。 增强的抗反射叠层在商业OLED显示器中表现良好，具有20％或更大的亮度增益，30％或更大的环境光反射增益，并且没有视觉上明显的图像劣化。
