Korean scientists have developed NTS technology for producing large-format transparent OLED screens, which can reduce their cost by 10 times compared to existing solutions. The new technology is based on the use of titanium dioxide nanoparticles uniformly distributed over an ultra-thin film.

Transparent OLED technology has come a long way since the first prototypes, but high production costs have held them back from widespread adoption. According to New Atlas, a team from the Nanolithography and Manufacturing Research Center at the Korea Institute of Mechanical Engineering and Materials has unveiled NTS (Nano Transparent Screen) technology that promises to change that.

NTS is based on the uniform distribution of titanium dioxide nanoparticles with a diameter of only 100 nanometers across the entire surface of the film. This film, according to the developers, is “as thin as a human hair,” and the image is projected onto it using a high-resolution projector. This achieves high-quality images with a wide viewing angle of 170 degrees. An additional polymer film with liquid crystal can adjust the opacity of the background, improving image clarity in bright lighting conditions.
Interestingly, NTS technology is not afraid of extreme temperatures and aggressive weather conditions, which opens up wide application prospects. For example, shop windows, smart windows, outdoor and indoor advertising are just some of the possible use cases. The developers have already demonstrated the capabilities of the technology in practice by installing a transparent screen in the Youth Mall shopping center in Gongju (a city in South Korea).
Today, the cost of a regular 100-inch transparent OLED screen exceeds $72,000, making it unaffordable for a wide range of consumers, while cheaper transparent LED screens have not gained popularity due to their low resolution. NTS’ capabilities promise to solve this problem by offering mass production of screens at a price 10 times lower than that of OLED analogues.
“The nano-transparent screen manufacturing technology is an advanced, innovative technology created by combining nanomaterials and nano-manufacturing technology with existing IT technologies,” said project leader Jun-Ho Jeong. “In the future, we will focus on research and development to continuously improve the quality of NTS to become the first to popularize transparent screens.”
In addition to its affordable price, Nano Transparent Screen promises flexibility and scalability. The developers claim that it will not be difficult to create transparent screens larger than 100 inches in the future. Work has already begun on commercializing the technology.
