UTG
A cover material used in foldable-screen smartphones, characterized by bendability, scratch resistance and high light transmittance.
Timeline (last 90 days)
Book-style inward-folding designs generally use ultra-thin flexible glass (UTG) to cover the inner screen and leave a bending radius in the hinge area to control the crease.
The mainstream approach for foldable inner-display cover layers is to stack a surface-treatment layer on ultra-thin flexible glass (UTG) or transparent polyimide (CPI) film.
Apple's long absence from foldable screens is widely believed to be a wait for hinge durability, UTG (ultra-thin flexible glass) yield, and system-level large-screen adaptation to mature simultaneously.
Ultra-thin glass (UTG) cover panels are typically only 30–50 micrometers thick and carry the risk of microcrack propagation under extreme temperature changes.
Samsung has developed an ultra-thin glass (UTG) cover solution with a thickness of only 30 micrometers, approximately one-third the diameter of a human hair.
Ultra-Thin Glass (UTG) technology has gradually replaced the plastic protective layers used in early foldable screens.
Samsung's UTG (Ultra-Thin Glass) technology has reached its third generation, with hinge lifespan increasing from an initial 200,000 cycles to over 400,000 cycles.
Samsung Display's third-generation UTG technology has reduced crease visibility by approximately 40% and the folding lifespan exceeds 200,000 times.
UTG technology raises screen hardness from the 2-3H of CPI materials to 6-7H.
Samsung first applied UTG technology to the Galaxy Z Flip in 2020, compressing glass thickness to 30 micrometers and improving hardness to 6-7H.
