Asahi Glass, a Tokyo based company, has come up with the thinnest glass substrate so far, measuring 0.28 mm. The glass substrate is 15 per cent thinner and lighter than what is being used now.
It resides between the glass cover and the LCD (liquid crystal display) screen.
If used, it will make tablets and smartphones even lighter.
Asahi had also come up with the most durable glass cover, DragonTrail, some time ago and it is already in use in numerous gadgets.
Touchscreen glass is made of chemically strengthened cover material and substrate material, which has electrodes in it. Soda lime substrates are popular among smartphone and tablet manufacturers as they retain their shape even when they are subjected to heat, and do not get discoloured in the face of ultraviolet radiation.
Glass touchscreens are produced using the float process, which involves floating the glass over molten metal, which results in the production of extremely uniform glass.
Notably, thinner glass is flexible but prone to damage.
