Samsung to unveil next-gen flexible and transparent AMOLED displays at CES 2011

There’s bound to be all manner of display technologies vying for eyeballs at CES 2011 when it kicks off in Las Vegas next week and two prototype AMOLED displays from Samsung Mobile Display (SMD) will definitely be high on our list of things to check out. The first is a 4.5-inch 800 x 480 (WVGA) resolution flexible AMOLED display concept prototype for mobile devices, while the second is the world’s largest transparent AMOLED display prototype for use in PC monitors and TVs.
Flexible AMOLED display prototype
SMD’s 4.5-inch flexible AMOLED display is two millimeters (0.08-in) thick and can be rolled down to a radius of one centimeter (0.39-in). The concept prototype’s 800 x 480 resolution, which Samsung claims is four times that of the previous most flexible AMOLED prototype constructed, comes courtesy of a new plastic substrate that can withstand the 450-500 degree Celsius temperatures required in the manufacturing process.
As this overcomes the problem of previous plastic materials melting during the manufacturing process that made commercialization of such devices difficult, Samsung says the concept display on show marks a major step on the road to mass production for the next-gen display, which is aimed at smartphones and tablet PCs.
Transparent AMOLED display prototype
The second prototype display to be unveiled is aimed at larger screen applications such as TVs and PC monitors. The 19-inch transparent AMOLED display prototype sports a qFHD (quad Full High Definition) resolution. This is a non-standard resolution of 3840 x 2160 pixels arranged in a 16:9 aspect ratio that gets its name from being four times the resolution of 1080p.
The prototype display is the world’s first large transparent AMOLED display prototype and, while the average amount of transparency previously achieved has been below 10 percent, SMD’s display maintains up to 30 percent transparency whether it is turned on or off. Samsung says this will allow the technology to be used for surfing the internet while watching TV or even watching TV on windows – and by that it means the glass kind, including car windows, not the operating system.
As well as the 19-inch prototype, SMD will also be exhibiting a 14-inch qFHD transparent AMOLED display designed for notebooks.
