OLED-Info reports that researchers from the Samsung Advanced Institute of Technology in South Korea developed a new seamless foldable touch AMOLED display that can fold in half without showing a visible crease. Samsung says that current research is mostly geared toward flexible/bendable displays , but a display that can be folded in half is great for making a large display in a portable form.

To make the seamless display, the team used two AMOLED panels, silicone rubber, a glass cover and a modular case. Their prototype was folded 100,000 times - and still the brightness at center of the display (where the two panels meet) decreased by just 6% - which is hardly visible by a human eye.

Samsung says that commercialization of such a device will take one or two years - as new materials and processes must be developed.

Samsung has been working on foldable OLEDs for quite some time. In December 2010, the company showed a concept 3D TV that uses two foldable OLED panels. In 2009, they demonstrated a foldable phone with two AMOLED panels.
