Unanswered Questions

How does the aspect ratio of the absorptive regions affect the performance of the light control film?

The aspect ratio of the absorptive regions is crucial in determining the efficiency of light absorption and transmission in the film. A higher aspect ratio may lead to better light control capabilities, but it could also impact the overall transparency of the film.

What materials are typically used in the production of light control films with alternating transmissive and absorptive regions?

The choice of materials can significantly influence the performance and durability of the light control film. Understanding the specific materials used can provide insights into the film's optical properties and potential applications.

Original Abstract Submitted

A light control film comprises a light input surface and a light output surface opposite the light input surface. Alternating transmissive regions and absorptive regions are disposed between the light input surface and the light output surface. The absorptive regions have an aspect ratio of at least 30 and the alternating transmissive region and absorptive regions have a relative transmission at a viewing angle of 0 degrees of at least 75%.
