File:Samsung rollable mobile phone

Advantages[edit]

Rollable display has many advantages than glass: better durability, lighter weight, thinner dimensions, and can be perfectly curved and used into any devices.^[1] Moreover, the major difference between glass and rollable display is that the display area of rollable display can be bigger than the device itself. It means if a flexible device having 5 inches in diagonal and a roll of 7.5mm, so it can be stored in a device smaller than the screen itself and close to 15mm in thickness.^[2]

Apply[edit]

Due to the flat panel display has already been wildly used more than 40 years, it is the time to improve the display technology to a lighter, thinner and easier way to carry and storage. Though the development of rollable display in recently years, the scientists and engineers agree that the flexible flat panel display technology has the huge potential market and industry in the future .^[3]

Rollable display can be used in many places:

1. Mobile devices.

2. Laptops and PDAs.

3. A permanently conformed display that securely fits around the wrists. ^[4]

4.A child's mask for Halloween and other uses.^[5]

5.An odd-shaped display integrated in a steering wheel or automobile.^[6]

Overall, there are plenty of new devices and technologies will be invented with the development of rollable display technique.

SAMSUNG YOUM[edit]

In January 2013, Samsung exposed their brand new unnamed product when the company's keynote address at CES in Las vegas. Brian Berkeley, the senior vice president of samsung's display lab in San jose, California. He said: " the technology will let the company's partners make bendable, rollable, and foldable displays", and he actually showed how the new phone can be rollable and flexible during his speech. ^[7] Samsung officially released their first flexible mobile phone called "Youm". "Youm" has curved display screen, the use of OLED screen giving this phone deeper blacks and a higher overall contrast ratio with better power efficiency than traditional LCD displays. ^[8] Also this phone has the advantages of rollable display, it is lighter, thinner and longer durability than LCD displays.

Samsung did not give a specific date to launch "Youm" in the market. However, Samsung stated that "Youm" panels will be seen in the market in a short time, it will be produced in 2013. ^[9]
