Abstract: Foldable substrates have a first portion, a second portion, and a central portion positioned therebetween with a first transition region having a first central surface area of the central portion with a first average angle. In aspects, the first average angle is from about 176.10 to about 179.9° or from about 177.0° to about 179.9°. In aspects, a polymer angle is from 178.3° to about 179.9° or from about 179.10 to about 179.9°. Methods comprise disposing an etch mask over the first major surface of the foldable substrate before etching the foldable substrate. In aspects, the etch mask comprises a first polymer layer positioned between a first barrier layer and the first major surface. In aspects, the etch mask comprises a plurality of ink-jet printed shapes. Methods of measuring a contrast ratio comprise impinging a transparent apparatus with a collimated beam.
