Samsung to demo 4.5-inch flexible AMOLED displays at CES 2011

Samsung Mobile Display (SMD) will be demonstrating a prototype of the most advanced flexible AMOLED display during the CES, at the Caesars Palace Hotel on Wednesday, January 5th from 7 to 10pm. Only 2mm thick, the 4.5 inch flexible AMOLED runs at a WVGA 800 x 480 resolution and can be rolled down to a one centimeter radius. At WVGA, this new concept prototype offers a display resolution four times that of the previous most flexible AMOLED prototype in the industry, thanks to the use of a new plastic substrate that can withstand the 450-500 degree temperatures required in the manufacturing process.

According to the press release,

Typically, flexible displays use plastic substrates instead of glass substrates because this helps the display become lighter and thinner. Furthermore, the new plastic substrates are not prone to breakage during manufacturing. Previously, plastic materials melted at temperatures over 400 degrees during the manufacturing process, making commercialization difficult.

Development of the 4.5 inch Flexible AMOLED prototype, designed for smart phone and tablet PC displays, is a major step on the road to mass production.
