UTG(Ultra Thin Glass)
UTG
- 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.
