Even Samsung bought it... Metamaterial principles and commercialization in action that would surprise even Ditto (feat. metasurfaces and metalenses) | When? Ep17
- What to look for
- Explore the principles and real-world development of metasurfaces, from displays that switch to 3D and camera and Face ID applications to nanoimprinting for mass production.
- Why it matters
- Understanding how nanostructure design changes optical performance and manufacturing costs helps you interpret news about the commercialization of new materials.
AI summary
It introduces metasurface technology, which controls light and sound waves using tens of billions of protrusions on a flat glass plate, as a technology about to enter the world, starting with smartphones. It shows a smartphone display demonstration in which a metalens conversion device between the panels switches between 2D and 3D with a single button. It explains that an array of 250 hundred-million meta-atoms, each 100 nanometers in size, or 1 thousandth of 1 hair's thickness, simultaneously provides convex and concave functions to switch lenticular-lens images. It reports that a single sheet corrects aberrations to make phone cameras thinner, that a dot projector 5 times smaller than Apple's was developed, and that Samsung bought the related patent for approximately 10 hundred-million won. It says the world's first mass production was verified using nanoimprinting, which replicates patterns costing tens of millions of won for a few thousand won, and roll printing at 300 units per second, and forecasts commercialization within 5 years. All directional outlooks are the speaker's conditional judgments, not definitive short-term price predictions.
