With the rapid development of science and technology in recent years, with the ever-changing electronic intelligence products, from mobile phones, tablet computers to watches and glasses, etc., both shape and function are constantly refreshing people's attention, but also bring users Brand new feeling. However, the only thing that has not changed is the toughened glass screen, and the recent advent of flexible display technologies such as wallpaper OLED (organic light-emitting diode) display panels and "green" flexible electronic paper make us feel that the era of flexible electronics Is within reach.

Watching the "Harry Potter" series of movies, dynamic magazines that I am afraid that many people left a deep impression. In some ways, this can be regarded as a flexible display screen. How wonderful this magic comes true!

With the rapid development of science and technology in recent years, the ever-changing electronic intelligent products, from mobile phones, tablet computers to watches and glasses, are continuously refreshing people's attention both in shape and function, and also bring new feelings to users . However, the only thing that has not changed is the toughened glass screen, and the recent advent of flexible display technologies such as wallpaper OLED (organic light-emitting diode) display panels and "green" flexible electronic paper make us feel that the era of flexible electronics Is within reach.

Wallpaper OLED display panel

Is there an OLED display that can be easily attached to a wall like paper and then removed for reuse?

According to a recent report by the Physiologist Network, South Korea's LG Display Corp. unveiled a sleek new product in Seoul with a thin, wallpaper-like OLED panel measuring 0.97mm in length and 55 inches in length and weighing 1.9kg. When in use, it can be easily mounted on the wall with a magnetic pad, and if you are not satisfied with the position of the display, you can always take the adjustment position.

In contrast, LG monitors the existing 55-inch OLED panel 4.3 mm thick, the insiders commented: "The benefits of the new product is the increase of large-screen placement possibilities, it is easy to bend into the living room."

The use of magnetic pads, the screen is easy to be adsorbed on the wall, to remove the display panel from the wall, just peel off the screen under the magnetic pad. South Korea's Yonhap news agency said in a report that it is easily removable wallpaper OLED display panel.

"Green" flexible electronic paper

E-book terminals in the promotion of the market, e-paper found the driving force for development. Experts in technology research and development have long predicted the advent of the flexible electronics era. Researchers have worked hard to achieve compliance in many ways, but many products rely on petroleum-based plastics and toxic substances. And thanks to the maturity of flexible substrate technology, flexible display device is not far from the large-scale practical, on this basis, the researchers sought to develop a flexible green electronic paper.

According to a report by the Daily Telegraph a few days ago, through a simple suction filtration method, scientists first developed a shiny, transparent and flexible electronic paper material, making flexible electronic products to a new level.

The product is a thin, clear nanocellulose made from wood flour, on which researchers impregnate biocompatible quantum dots, small semiconducting crystals made of zinc and selenium. The paper glows at room temperature and can be rolled up without cracking.

The findings were published in the ACS issue of ACS, the latest issue of the American Chemical Society.

Flexible folding phone

Bendable, collapsible phones seem to be products that are seen in some science-fiction movies, but that's not what's coming in the future. In fact, technical engineers have been working on flexible screens for many years. Even earlier, some international manufacturers once released the concept map, which surprised many mobile phone users.

In fact, as early as 2011 CES (International Consumer Electronics Show), Samsung introduced flexible screen technology, and even then there are rumors that the technology will be used in Samsung GALAXYS3 and GALAXYNote Ⅱ. But this time Samsung's Youm flexible display panel technology is more mature, to produce bendable, twisted and folded display. In addition, at the CES2013 show Sharp also brought a 3.4-inch flexible LED screen can be bent, the international giant Intel also jointly Plasticicon exhibited a flexible screen tablet.

However, the real sense of a flexible phone will not be realized in the short term, but after the "stereotyped" flexible screen phone is still expected to market, such as Samsung CES2013 show on the right side of the screen has a certain downward tilt OLED screen prototypes from the point of view, except for the rest of the screen, do not require special design.

Wearable device development

In the future, flexible display materials will meet the needs of wearable devices for on-screen displays with the advantages of bendable, ultra-slim design, ultra-low power consumption, durability and portability.

Wearables, represented by Google Glass, smart watches and health monitoring wristbands, will become the "fourth platform" after televisions, computers and mobile phones. Wearable devices are expected to be the next explosive growth point after smartphones .

When the five major platforms of Apple, Google, Microsoft, Amazon and Facebook, and corresponding developers are competing into the field of wearable devices, wearable devices will become the mainstream when the background data and front-end detection and transmission are improved. According to the latest statistics, consumers click and share content on their mobile devices twice as fast as their desktop counterparts, and the data available for sharing explodes as social networks become more important.

The mainstream applications of wearable devices include infotainment and social sharing, medical and health monitoring, military and industrial applications. At present, most wearable devices are in the form of portable accessories that can be connected with mobile phones and various types of terminals, and mainstream ones Products include wrist-supported watches; foot-supported footwear, including shoes, socks, or other future legs; and eyeglasses supported by the head, including eyeglasses, helmets and headbands, As well as smart clothing, bags, crutches, accessories and other non-mainstream product form.
