The brightness enhancement film is a transparent optical film. It consists of a three-layer structure. The bottom layer of the light-incident surface needs to provide a certain degree of haze by back coating, the middle layer is a transparent PET substrate layer, and the upper layer of light-emitting cotton. It is a microprism structure. When the microprism layer passes through the fine prism structure of the surface layer, the light intensity distribution is controlled by refraction, total reflection, light accumulation, etc., and the light scattered by the light source is concentrated toward the front side, and the unused light outside the viewing angle passes through the light.
So, it's similar to your design, but the grooves are very small.

To experienced LLM users that's not surprising at all - providing citations, sources for quotes, useful URLs are all things that they are demonstrably terrible at.
But it's a computer! Telling people "this advanced computer system cannot reliably look up facts" goes against everything computers have been good at for the last 40+ years.
