Jin ah Hwang’s business card is unique. It’s a thin, clear film with a rectangle that has been turned an opaque white, superimposed with multi-colored text.

The card is a demonstration of the products made by her company, Chungju, South Korea-based Livicon Co. Ltd. Its 0.39 mm to 0.12 mm thick film can attach to glass or plastic and has a range of potential uses.

Hwang described those possibilities Monday night at The Milwaukee Club upon meeting Robert Tatterson, Ph.D., an advisor and investor in early stage companies. Having retired a few months ago from his position as chief technology officer at Sealed Air in Racine, Tatterson has been evaluating new technology companies for investment and mentorship opportunities, he said.

“It’s been interesting to meet businesses in all different stages of maturity,” he said. “I have a background in technology and I’m really passionate about new product development and innovation.”

Livicon films are installed at the tallest building in South Korea, the 123-floor Lotte World Tower, on a glass skywalk floor. Visitors walk out onto the opaque skywalk, and suddenly it turns clear, revealing Seoul below. The films are also installed in some offices’ glass-walled conference rooms to offer privacy during meetings, and on companies’ storefronts to either allow customers to see in during the day, or display a large advertisement on the opaque screen off-hours. The films could be used as blinds in a home or to block the sun on car windows, she said. Read the full story here.
