SEOUL, July 3 (AJU PRESS) - The Korea Institute of Machinery & Materials (KIMM) has successfully commercialized a 100-inch nano transparent screen that can be mass-produced at a fraction of the cost of existing technologies.

The innovation, developed in collaboration with Meta2People, allows for adjustable transparency based on ambient lighting and image information.

The new screens utilize titanium dioxide nanoparticles dispersed within a film as thin as a human hair. When combined with polymer-dispersed liquid crystal (PDLC) film, the screens can adjust their transparency to enhance image clarity in various lighting conditions.

Unlike traditional transparent OLED or LED displays, which are either expensive or suffer from low resolution, these nano-transparent screens offer high-resolution images at approximately 10 percent of the cost of transparent OLED.

"The technology for manufacturing nano-transparent screens is a cutting-edge, innovative technology created through the combination of nanomaterials and nanomanufacturing technology with existing IT technologies," Jeong Jun-ho, principal researcher at KIMM's Nano-lithography and Manufacturing Research Center, said,

The screens are expected to find applications in various fields, including transparent display cases in department stores, smart windows for buildings and promotional displays for both indoor and outdoor use. The technology is showcased at Nano Korea 2024, the country's largest exhibition of its kind, from Wednesday to Friday at KINTEX in Ilsan.
