The Making of Ultra Thin Glass, For Smartphones And Smartwatches

These pieces of glass are thinner than a single human hair. Its thinness allows it to flex like plastic and have greater electrical sensitivity for use as screens for smartphones and smartwatches.Hardened ultra-thin glass is scratch-resistant and bendable up to a radius of a few millimeters and doesn’t show any signs of fatigue.

By using innovative materials and its own proprietary down-draw technology, they can reliably produce ultra-thin glass as thin as 25µm today. These glasses offer many advantages over other materials such as plastic or silicon, support the trend toward miniaturisation and make exciting concepts possible in the race to develop smartphone technologies of the future.

Ultra-thin glass also withstands the increasing heat generation of high-performance processors in smartphones better than plastics that are currently being used in chip packaging. Even the thinnest glass does not bend during use and thus makes extremely flat device types possible.


Furthermore, it has excellent barrier properties and protects against environmental influences. This makes it an ideal substrate or encapsulant for OLEDs that ultimately make bendable or foldable displays possible.

This then opens the door for manufacturing flexible smartphones or so-called wearables, in other words devices that can be worn as bracelets or be integrated into textiles.
