World's Thinnest Glass Substrate for Touchscreens is 15 percent thinner

Just after a few months of introducing the world’s strongest glass, AGC or Asahi Glass Co, has unveiled last week in Japan a new soda-lime glass substrate for touchscreen displays just 0.28mm or 15% thinner than other previous models. Making it the World’s Thinnest Glass Substrate for Touchscreens.

The innovation will further enable smart device makers to make slimmer and lighter handsets.

Glass touchscreens in smartphones and tablets comprise a tough cover material and an underlying layer of substrate material embedded with electrodes. Soda-lime glass is an ideal substrate material for touchscreens because it maintains form when subjected to heat, resists discoloring due to ultraviolet radiation, accepts chemical strengthening and is easily processed.

• Soda-lime glass, composed mainly of sodium oxide and silicon dioxide, is used widely in construction, automotives and many types of electronic devices.

• The float process is a glass-manufacturing method in which glass is floated over molten metal for the efficient production of highly uniform glass.

• Chemical strengthening is a technology for submerging raw glass in chemicals to strengthen its surface.

AGC says that the new glass substrate will start being mass produced within a couple days in Japan and will be introduced formally at SID in North America next month. --------
