Nanostructured holographic antireflection films

Antiglare (AG) and antireflection (AR) properties are important optical features of the front surfaces of flat panel displays and other information displays. AR as well as AG surfaces can be generated as surface-relief structures using holographic processes on large areas suitable for use on flat panel displays. The seamless structured area has now been increased to 600mm × 800mm. Size is the important success factor for nanostructured AR films. The latest development in the field is a superposition of an AG structure and an AR structure (MARAG1). Such structures can be mass-produced by precision nanoreplication, which has been demonstrated in a continuous filmUV nanoreplication (UV-PNR) proces. The resulting surface not only shows the desired optical properties, but is also equipped with a hardcoating suitable for the real world. All features are added in the same replication process: hardcoat, AR and AG.
