摘要： A diffuser stack may include a first film with a first index of refraction and a second film proximate the first film. The second film may have a second index of refraction that is higher than the first index of refraction. An interface between the first film and the second film may include an array of microlenses of substantially randomized sizes. The microlenses may include sections of features that are substantially spherical, polygonal, conical, etc. The first and second films may be disposed between an array of pixels and a substantially transparent substrate. An anti-reflective layer may be disposed between the first film and the second film.

摘要： An apparatus may include a first layer having a range of first layer indices of refraction. The range of first layer indices of refraction may include at least two indices of refraction. The apparatus may include a second layer proximate the first layer. The second layer may have a second index of refraction that is outside (e.g., lower than) the range of first layer indices of refraction. An interface between the first layer and the second layer may include an array of microlenses of substantially randomized sizes. The microlenses may include sections of features that are substantially spherical, polygonal, conical, etc. According to some implementations, the first and second layers may be disposed between an array of display device pixels and a substantially transparent substrate, such as a glass substrate, a polymer substrate, etc.
摘要翻译：装置可以包括具有第一层折射率范围的第一层。第一层折射率的范围可以包括至少两个折射率。该装置可以包括靠近第一层的第二层。第二层可以具有在第一层折射率的范围之外（例如，低于）的第二折射率。第一层和第二层之间的界面可以包括基本上随机化的尺寸的微透镜阵列。微透镜可以包括基本上是球形，多边形，圆锥形等的特征部分。根据一些实现方式，第一和第二层可以设置在显示装置像素阵列和基本上透明的基板（例如玻璃基板）之间，聚合物基材等
