UTG

UTG(Ultra Thin Glass)

As a key component of foldable smartphones,
this ultra-thin tempered glass is thinner and more durable than plain tempered glass.
Secured the technology to remove progressive micro-cracks that break the glass upon impact and the chemical strengthening technology to achieve the minimum R value of the glass radius.
Secured glass surface treatment technology to maintain stable repeatability of 250,000 times.
Establishment of mass production system by developing dedicated facilities to secure stable productivity and improvement of yield.
With UTG for foldable phones, we manufacture the glasses in the desired shapes of our customers, with 30~70㎛ thickness, and provide a total solution for PET film lamination.
Moreover, we are capable of producing large-size UTGs such as tablets, laptops, and monitors, including sizes of 6.7-inches to 8.2-inches for foldable smartphones.
