Samsung researchers have reportedly solved the crease problem with foldable displays which means full size tablets could soon fit in your pocket, according to Physorg.
In the new study, the researchers have overcome this problem, demonstrating a seamless foldable active matrix organic-light-emitting-diode (AMOLED) display with no visible crease. The display consists of two AMOLED panels, silicone rubber (a hyperelastic material), a protective glass cover, and a module case. The display has a very small folding radius of just 1 mm, so that one panel lies almost completely on top of the other when the display is folded at a 180° angle. Also, the glass cover not only prevents scratches, but can serve as a touch screen, as well.
The display was tested by folding and unfolding it 100,000 times. This resulted in a brightness decrease of 6% at the junction, a difference hardly noticeable by the human eye.
"All the materials in a foldable window unit (glasses and silicone rubber) must have almost the same optical properties and attach to each other strongly without any optical property change," HongShik Shim of the Samsung Advanced Institute of Technology told PhysOrg.com. "Our method has the advantage that mature, high-quality AMOLED display panels already exist but for real commercialization, some new processes and new materials must be developed, which takes about 1-2 years."
