Abstract
Display modules typically incorporate a transparent hard material such as glass on the outside of the module in order to better protect the display stack from scratches, dents, and other mechanical deformations. However, as displays move to novel form factors such as bendable, foldable, and reliable display modules, these transparent hard materials (e.g., glass) may not be used due to their limited flexibility. Therefore, it is desirable that replacement materials be sufficiently flexible while maintaining the desirable optical (e.g., >90% transmission and low yellow index) and mechanical properties (e.g., pencil hardness>H) that comparable glass hard materials offer.
