One of the most difficult problems faced now a dayz for designing mobile devices is to minimize the size of the device while simultaneously maximizing the size of the display. To get the best of both worlds, researchers from the Samsung Advanced Institute of Technology have designed and built a prototype of a seamless foldable display that folds in half without a visible crease in the middle.
As the researchers explain in their study,recently there has been a great deal of interest in flexible, extendable displays. Most of these flexible displays are bendable or rollable. Fabricating a display that can fold completely in half would have the advantage of providing a large screen in a small, portable form,so far its been a challenge for researchers to decrease the crease between two displays.
In the new study, the researchers have overcome this problem, demonstrating a seamless foldable AMOLED display with no visible crease. The display consists of two AMOLED panels, silicone rubber(The silicone rubber is commercially available, which could make it suitable for mass production.), a protective glass cover, and a module case. The two panels have a folding radius of 1 mm only, so that one panel lies almost completely on top of the other . also the glass cover not only pevents scratches bt also serves as touch screen.
In fact, the developers performed 100,000 folding-unfolding cycles to test the junction; the negligible 6% decrease in brightness was invisible to the human eye.
As for applications, a foldable display can be used in a wide variety of small devices such as mobile , cellular phones, tablet PCs, and notebook PCs. In addition, the researchers plan to investigate applying this design to fabricate large-size flexible displays.
