AI Technical Summary
Conventional display device cover members, particularly those made of glass, face challenges in balancing impact resistance, flexibility, and safety due to their high elastic modulus and tendency to break when thinned for flexibility.
A display device member comprising a thin glass substrate with a resin layer on one surface, where the resin layer has a composite elastic modulus of 5.7 GPa or more and a thickness of 5 μm to 60 μm, enhancing impact resistance and flexibility while maintaining surface hardness.
The solution provides a display device member with improved impact resistance, flexibility, and safety, preventing glass fragmentation and enhancing scratch resistance, while maintaining optical transparency and flexibility for foldable displays.
