OLED in the future wearable devices widely used

Imagine, if you put the mobile phone in his jeans pocket, even sit down and don't dig it out, because it is not afraid of fold, even if bent can be straightened, it is not so handsome? If your mobile phone has a shock, even by the deformation of the hammer also never mind, because it is soft also, breaking the back, isn't that cool? This is not just a science fiction movie, flexible screen mobile phone may be able to create a miracle.

Not long ago, LG and Samsung almost simultaneously launched a flexible screen phone, NOKIA has also recently applied for a curved folding battery patent. Take the lead in the role of the eldest brother of the mobile phone is self-evident, starting from Apple touch screen boom, as well as Samsung opened a large screen prelude is evident. In this case, the flexible screen phone seems to fire up.

However, the flexible screen is currently mainly based on OLED technology, Samsung, LG, who still have confidence this site? Furthermore, do not fix a flexible screen mobile phone screen can be finalized, but also the batteries, glass and a series of key devices can support. So, flexible screen phone is quite beautiful, but really want to do it or not blind break.

Screen neck block

Flexible display is mainly based on OLED technology to do, the traditional TFT panel can not achieve flexibility, while domestic enterprises in the relevant technical reserves is still relatively weak.

Now on the market most of the mobile phones are using TFT-LCD screen, a number of high-end products using IPS technology, there are some positioning tall on the phone application AMOLED screen. Compared to OLED, TFT-LCD technology is more mature, more market-oriented products. But flexible screen just based on OLED technology.

In October this year, LG Display announced the beginning of the production of the world's first smart phone with flexible OLED panel. Almost at the same time, Samsung also released the first flexible OLED screen phone Galaxy Round. DisplaySearch analyst Terry told reporters that the current domestic production has not yet achieved flexible display, even Samsung and LG capacity planning is not high. But according to his understanding, Samsung next year will increase the capacity of flexible display.

The flexible display is mainly based on OLED technology, the traditional TFT panel can not achieve flexible, and domestic enterprises in the relevant technical reserves is still relatively weak, and this is the main reason for the current domestic manufacturers have not done flexible displays. "Terry says. A few months ago, the first domestic color flexible AMOLED display in the Guangzhou New Horizons Photoelectric Technology Co., ltd.. In just the end of the fifteenth China Hi Tech fair, BOE official told reporters: "there is no BOE flexible screen, Ordos 5.5 generation line, will be used for the production of flexible screen. "

As a leader in the domestic panel industry, the BOE's answer seems to domestic flexible display industry Zhaxian dawn, but think about the production line from production to production process, as well as the domestic situation in the OLED technology, the light seems to be a little far.

In Terry it seems that Samsung's production of flexible screen phone is mainly the performance of its market strategy, hoping to further expand their own leading edge in the field of OLED. But for now, even if the Samsung display flexible screen phone, but also not really flexible. Samsung Galaxy Round and LG G two flexible screen phone is only equipped with a curved screen, in the actual use of the meaning is not large in the Flex. Flexible screen in the future should be free to bend, fold, and now is only the initial stage of development.

Key devices suck

To produce flexible screen phone, in addition to the screen, but also need to match the body material, power, batteries and other support, and these key devices is still difficult to meet the requirements.

In the expert opinion, flexible display industry has not developed, in the process, equipment commissioning, yield and other aspects are facing many problems. The production of flexible screen phone, in addition to the screen, but also need to match the body material, power, batteries, etc., so the short term flexible screen phone is difficult to form a climate.

Said the first mobile phone screen material, soft, how to do the? Now mobile phone whether it is plastic shell or metal shell, are difficult with the performance of flexible screen bent or folded, but also continue to find new materials.

Look at the glass, the current mobile phone glass screen is used as the basic protection, bending, folding glass screen if the long break to break, wear and tear is inevitable. So now the flexible screen device to choose a plastic screen. Glass screen flexible OLED panel LG Display launched on the use of plastic screen and very see, the panel becomes flexible, not easily broken; at CES earlier this year, Intel also unveiled a flexible PaperTab tablet computer, the same application of flexible plastic display. However, the plastic screen in the permeability, sensitivity and other aspects of the glass, and the relevant technology is not yet mature.

There are batteries, mobile phones are now the use of lithium batteries large, hard, which ensures a long endurance. It may be difficult to make the battery bend with a soft phone, and a new solution is needed.

In this way, the phone is not really you want to break, you can break.

Wearable device applications

Flexible AMOLED screen is relatively light, if it can be folded, bent will be more portable, and not easy to break. These characteristics determine its wearable device will have a wider application space.

It is understood that Samsung has
