Scientists have devised a new approach to making large, transparent screens at low cost — and they hope it could lead to more affordable transparent TVs in the near future.
In addition to its light and flexible appearance, the panel's transparency can be adjusted — with the screen capable of showing the most detail when at its most opaque. It is also highly reflective to targeted light, producing clear images when hit with a beam from a powerful projector, and has a lossless 170-degree viewing angle on either side.
These nanoparticles give the NTS its durability and improve the optical quality of the film, the scientists said, meaning images projected onto it remain clear. The film is also layered with a kind of crystal polymer known as a polymer dispersed liquid crystal film. By applying an electrical field to the crystals, the PDLC can be made more or less transparent — allowing the screen to become more opaque when users want to see more detail on the screen.
