Abstract: Overlay is described. In particular, an overlay with integral tabs for a display is described. The integral tabs is made by a laser machining process, to obtain the required thickness of the tabs. The overlay described herein is particularly suitable for display screens of devices such as laptop, tablet computers, cellular phones etc.

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.
