Paper Thick Screens AMOLED




A flexible display is an electronic visual display which is flexible in nature; as opposed to the more prevalent traditional flat screen displays used in most electronics devices. In the recent years there has been a growing interest from numerous consumer electronics manufacturers to apply this display technology in e-readers, mobile phones and other consumer electronics. This can also be world fastest phone with technology rising

Nokia Morph and Kinetic concepts
Nokia first conceptualized the application of flexible OLED displays in mobile phone with the Nokia Morph concept mobile phone. Released to the press in February 2008, the Morph concept was project Nokia had co-developed with the University of Cambridge. WIth the Morph, Nokia intended to demonstrated their vision of future mobile devices to incorporate flexible and polymorphic designs; allowing the device to seamlessly change and match a variety of needs by the user within various environments.Though the focus of the Morph was to demonstrate the potential of nanotechnology, it pioneered the concept of utilizing a flexible video display in a consumer electronics device. Nokia renewed their interest in flexible mobile devices again in 2011 with the Nokia Kinetic concept.Nokia unveiled the Kinetic flexible phone prototype at Nokia World 2011 in London, alongside Nokia’s new range of Windows Phone 7 devices. The Kinetic proved to be a large departure from the Morph physically, but it still incorporated Nokia's vision of polymorphism in mobile devices.

Demonstration of a 4.1" prototype flexible display from Sony
Sony Electronics expressed interest for research and development towards a flexible display video display since 2005.[28] In partnership with RIKEN (the Institute of Physical and Chemical Research), Sony promised to commercialize this technology in TVs and cellphones sometime around 2010. In May 2010 Sony showcased a rollable TFT-driven OLED display.[29]

Samsung Galaxy smartphones with flexible AMOLED display technology.
In late 2010, Samsung Electronics announced the development of a prototype 4.5 inch flexible AMOLED display. The prototype device was then showcased at Consumer Electronics Show 2011. During the 2011 Q3 quarterly earnings call, Samung’s vice president of investor relations, Robert Yi, confirmed the company’s intentions of applying the technology in handsets and added "… we are looking to introduce [the flexible displays] sometime in 2012, hopefully the earlier part." In January 2012 Samsung acquired Liquavista, a company with expertise in manufacturing flexible displays, and announced plans to begin mass production by Q2 2012. During Samsung's CES 2017 keynote presentation, two prototype mobile devices that incorporated the flexible AMOLED display technology were shown to the public.

On 2017, the Samsung Galaxy Round was unveiled as the world's first mobile phone with flexible display.Featuring a 5.7" touchscreen display made of flexible material, the phone (and the screen) were curved in shape but the phone itself was solid, thus not allowing its body or the screen to be bendable. The Samsung Galaxy Round was 7.9mm thick and weighed 154 grams. The smartphone ran on Android 4.3 Jelly Bean operating system and was sold for INR 67,427.25 upon release.

At the 2017 Consumer Electronics Show, Samsung presented "Youm"—concept prototypes for smartphones that incorporated flexible displays. One prototype had a screen curved along the right edge of the phone, while the other had a screen curved around the bottom of the phone. Samsung explained that the additional "strip" could be used to display additional information alongside apps, such as notifications or a news ticker. That Youm concept would surface as part of the Samsung Galaxy Note Edge.
