Jntc

Jntc makes toughened glass components, such as the protective cover glass on smartphone and tablet screens, and waterproof USB-C connectors used in mobile devices.

Listed on KOSDAQ, Korea's tech-focused small-cap board, it supplies these parts to consumer-electronics manufacturers, with Chinese smartphone brands forming a significant part of its customer base. Its business runs across two divisions: an advanced-materials segment centred on various glass products, and a connector segment; the company is actively broadening its glass portfolio beyond mobile cover glass into glass substrates for semiconductors and glass platters for hard-disk drives.
