Carrying Devices into the Flexible OLED Future

Carrying Devices into the Flexible OLED Future

A look at your OLED phone’s glass beginnings

A flexible OLED device starts and ends with glass.

When you look at your Samsung Galaxy S9, you see sleek Corning® Gorilla® Glass 5, which is featured on both the front and back of the device.

But what you don’t see is the stunning OLED display’s glass beginnings.

Creating a high-performance OLED panel requires a demanding, high-temperature manufacturing process, so materials used in these displays should be structurally and thermally stable. High-performance display glass substrates – like Corning Lotus™ NXT Glass – are uniquely optimized to remain structurally stable despite high temperatures.

When set makers request that a mobile device’s display panel be molded, curved, or folded for its industrial design, panel makers add plastic – a polyimide layer, to be precise.

In this case, Lotus NXT Glass is the carrier glass substrate, providing a solid foundation to usher the polyimide backplane through this demanding process. With the Lotus NXT Glass carrier substrate as a stable base, a high-resolution panel can be built and remain thermally and structurally stable upon a malleable backplane material.

 Once the glass substrate carries the polyimide-based panel to fruition, a UV laser helps cleanly remove the carrier glass substrate. Now the polyimide-based panel can be bent and molded into today’s cutting-edge industrial designs.
