An optical system includes a lens layer including a plurality of microlenses arranged along orthogonal first and second directions, and at least one optically opaque mask layer spaced apart from the lens layer and defining a plurality of through openings therein arranged along the first and second directions. There is a one-to-one correspondence between the microlenses and the openings, such that for each microlens, the microlens and corresponding openings are substantially centered on a straight line making a same oblique angle with the lens layer. An optical layer can include the lens layer and the optically opaque mask layer embedded in the optical layer.

Optical layer and optical system

Provided is a barrier adhesive composition comprises polyisobutylene resin, organically modified nanoclay (e.g. montmorillonite or bentonite) and sorbent nanoparticles (e.g. CaO which acts as a desiccant and/or getter). In a preferred embodiment, the barrier adhesive composition is disposed on a gas-barrier film to form an adhesive barrier film. The adhesive barrier film can then be used for protection from oxygen and moisture in OLED displays and solid state lightings, solar cells, electrophoretic and electrochromic displays thin film batteries, quantum dot devices, sensors (e.g. touch sensor) and other organic electronic devices. The adhesive barrier film is especially well-suited for applications that require oxygen and moisture protection as well flexibility and good optical transmittance.
