This chapter investigates the central challenges that confront optical coatings as display technologies advance toward flexible, stretchable, foldable, and even holographic formats. While coatings have always been integral to managing reflection, transmission, and surface durability, their role is becoming increasingly complex with the adoption of unconventional substrates and multifunctional requirements. The discussion identifies adhesion, durability, and optical uniformity as the three most pressing bottlenecks that must be resolved for next-generation displays to achieve reliable performance. These interrelated challenges are framed within the broader context of how coatings interact with substrates, environmental stressors, and the demand for scalable manufacturing.

摘要

This chapter investigates the central challenges that confront optical coatings as display technologies advance toward flexible, stretchable, foldable, and even holographic formats. While coatings have always been integral to managing reflection, transmission, and surface durability, their role is becoming increasingly complex with the adoption of unconventional substrates and multifunctional requirements. The discussion identifies adhesion, durability, and optical uniformity as the three most pressing bottlenecks that must be resolved for next-generation displays to achieve reliable performance. These interrelated challenges are framed within the broader context of how coatings interact with substrates, environmental stressors, and the demand for scalable manufacturing.
