Substrate vs. Cover Glass: What does each do?

Increasingly, it is the glass substrate that is doing more and more of the “work” of the display in the device. The substrate is what makes the display and device…

• Thin so you can reduce thinning costs and decrease carbon footprint
• Responsive for things like touch screen applications
• Very high pixel count displays for noticeably better resolution and clarity
• More dynamic color with the potential to go even thinner (OLED)

The explosion of touchscreens has helped advanced glass innovations expand beyond display substrates to now incorporate cover glass technologies that support functionality, expand design options and create a more durable interface.

The newest display products leading the market today include several different pieces of advanced glass used in a combination that allow for a distinctive design, high-performance display and/or customer piece of mind regarding durability.

While Corning’s advanced display glass – both substrates and cover glass – are formed with the same manufacturing process, the chemical compositions of each type of advanced glass is different.
