This screen operates both indoors and outdoors, and can be adjusted to become transparent according to the user’s needs.
Using a new type of film material, scientists have developed a 100-inch transparent nano screen (NTS), as thin as a human hair, capable of displaying detailed images with high color and light clarity.
The screen shows the most detail at its highest opacity, while also reflecting well with target light, producing sharp images when projected with rays and offering a 170-degree viewing angle without distortion on both sides.

Researchers at the Korea Institute of Machinery and Materials (KIMM), in collaboration with the private company Meta2People, have begun the commercialization of this transparent nano screen.
They stated that the screen is produced through a roll-to-roll process, in which a film sheet is treated with tiny particles of titanium dioxide.
These nano particles provide durability to the NTS and enhance the optical quality of the film sheet, meaning the images projected onto it remain sharp. The film sheet is also coated with a type of polymer crystal known as polymer dispersed liquid crystal (PDLC).
By applying an electric field to the crystals, PDLC can become more or less transparent, allowing the screen to become blurrier when users want to see more details on it.
According to the researchers, to purchase a transparent OLED screen, users typically spend around $72,000. However, their new panel costs only one-tenth of that amount.
They emphasized that this type of screen can be mass-produced under existing manufacturing conditions and can withstand extremely high or low temperatures, meaning it can be used both indoors and outdoors.
The scientists hope that this new technology could lead to the production of more affordable transparent television screens in the near future.
The transparent nano screen technology has been patented The researchers have just begun their journey of commercializing the transparent nano screen, but they have already been granted a patent for their technology. “This is an advanced, innovative technology created through the combination of nano materials and nano manufacturing technology with existing IT technologies,” said Jun Ho Jeong, the lead researcher at the Korea Institute of Machinery and Materials. “In the future, we will focus on research and development to continuously improve quality and lead the popularization of transparent screens,” he added. |
