US 2022/0055348 A1 · BENDABLE ELEMENT

Abstract

The present disclosure relates to bendable elements. The bendable elements can be used in display covers for electronic devices such as smart phones. The elements have reduced delayed elastic deformation or creep when released from the influence of persistent mechanical stresses, e.g. unfolded from a folded position. The present disclosure also relates to covers for color filters, filter printed electronics, sensors for touch control panels, fingerprint sensors, mobile electronic devices, bendable/foldable displays that include the bendable elements as substrates, or other applications where a combination of high chemical stability, temperature stability, low gas permeability, flexibility, high strength, low thickness and premium cosmetic appearance is necessary. Besides consumer and industrial electronics the present disclosure could also be used for protection applications in industrial production or metrology.

Dependent claims

A bendable element having a thickness, a length and a width, and having a first and a second primary surface,

wherein the element can be bent to a bending radius of 5.0 mm without failure, and
wherein the element has reduced persistent deformation characterized by a total persistent deformation a0 of not more than 3.0 mm and a deformation recovery time b1 of less than 10 hours after bending the element to a bending radius of 15.0 mm for 24 hours at 25° C. and 30% relative humidity.

Dependencies are inferred from the claim text.
