Korea-based Sewon NC announced that it is entering the OLED-based optical patch business, based on technology developed by Kwangbio and Korea's KAIST institute.

We do not have many details, but apparently Professor Kyung-cheol Choi from KAIST developed OLED optical patches for phototherapy that can be used to treat pain and encourage skin regeneration. Following an investment agreement, Sewon NC has secured the rights to produce and sell the OLED patches.

The OLED optical patch developed a KAIST is a free-form platform that can be attached to the body. It is based on flexible OLED panels and is less than 1 mm thick. The patches have been tested with preclinical trials in the first half of 2022, which achieved excellent results. Sewon plans to expand the application of the patches to more fields, such as dementia, skin cancer, skin regeneration, wrinkle improvement, and other skin diseases.

Using OLED for medical phototherapy is not a new idea. UK-based PolyPhotonix, for example, has been researching OLED technologies for many years, and its first commercial product is be the Noctura OLED sleep mask which helps patients with Diabetic Retinopathy. Pioneer is supplying the OLED lighting panels for PolyPhotonix's mask.



In 2017 it was reported that KAIST, together with Korea's Engineering Research Center (ERC) are establishing a OLED light therapy engineering center. The photo above was released by KAIST back in 2017 when it announced the new center.
