Abstract
A curved display includes a display panel having a curved major surface and a light control film disposed proximate the display panel. The curved major surface is curved about a first axis, and a central portion of the curved major surface has a surface normal along a second axis substantially orthogonal to the first axis. The light control film includes a major surface having a substantially same shape as the curved major surface and includes a plurality of alternating optically transmissive and optically absorptive regions. In a cross-section orthogonal to the first axis, a transmissive region and adjacent absorptive regions define a central ray transmission direction through the optically transmissive region such that a light ray emitted by the display panel and transmitted through the optically transmissive region along the transmission direction is refracted upon exiting the curved display into a direction substantially parallel to the second axis.
