Moto released the Droid Turbo 2 yesterday. The appearance of this machine continues the strong tough style of Moto since the V3 blade era. The pure metal frame and the leather/ballistic nylon rear cover also show its top business machine status. In addition to the appearance loved by successful people, the biggest highlight of the machine is that it is equipped with the Shatter Shield technology that Moto has been developing for three years. It claims to have an indestructible screen. The press conference has demonstrated its super anti wrestling ability many times, which can be said to be crazy for publicity. At the same time, Moto also promises to provide up to four years of broken screen warranty service, which shows that Moto has full confidence in the anti broken screen performance of this screen. So what is the knack of Droid Turbo 2 with such strong resistance to falling? Let's start with the screen structure with Shatter Shield technology.
The anti falling screen adopts a five layer structure, with the outer two layers of protective glass, the inner layer of touch screen and flexible AMOLED display panel, and the bottom layer of aluminum alloy base plate to enhance the overall strength of the screen.
External protective glass - high strength protective layer to prevent scratches and abrasion.
Internal protection glass - high transparency shatterproof glass, with relatively low hardness but good toughness, to prevent shattering.
Double touch layer - to prevent the touch control failure caused by the collision of the screen, so a double touch sensing layer is adopted.
Flexible AMOLED display panel - bendable flexible display panel can absorb certain buffer.
Aluminum alloy base plate - the solid metal base plate can increase the overall strength and durability of the screen.
In addition to the ultra-high overall strength, the biggest feature of this screen is the use of flexible display panels. When the mobile phone falls, the screen of the general mobile phone is hard to touch. Although the gorilla glass is very hard, it will be brittle and easy to break. The inner layer of Moto's screen is made of flexible AMOLED material. When the mobile phone is hit, the flexible screen will act as a buffer and the screen will not break.
The flexible screen is commonly known as OLED screen, that is, the organic light-emitting diode in the above figure. Compared with the complex structure of traditional LCD screen, OLED can emit light by itself, so it can not rely on backlight, liquid crystal and other components, and is simpler in structure. It can be installed on flexible substrates such as plastic or metal foil. It is precisely because flexible materials are used as the substrate instead of hard glass. In addition to being able to bend, it also has a certain degree of flexibility. When encountering collision, it will produce distortion and deformation to absorb part of the vibration. Compared with traditional LCD screens, it has made significant progress in fall resistance. The Shatter Shield anti shatter screen technology of Droid Turbo 2 is developed based on this feature of flexible screen.
In addition to improving the fall resistance, another major feature of flexible screens is that they are flexible and plastic. In recent years, Samsung and LG have shown flexible displays at major electronic exhibitions for many times, which are mostly used for the ergonomic design of mobile phones and wearable devices. In the past two years, with the increasing screen size of mobile phones, some brands of mobile phones have even reached more than 6 inches. It is no longer a dream for mobile phones to be bigger than Facebook. In addition to the difficulty of holding and operating such a huge mobile phone, even putting it in your pants pocket has become a problem, and how to improve the convenience of operation has also become a challenge.
At this time, the flexible screen is in use. The LG Flex2 and Samsung Galaxy Round are examples. The phone itself has a certain radian. In addition to better fitting the palm to improve the grip, the curved screen can effectively reduce the operating distance between the fingers and the two edges.
In addition to mobile phones, flexible screens can also be used on smart watches, sports bracelets and other devices. Friends who have used such products may know the trouble of smart watches - the screen is too small to operate, and the screen is too large and uncomfortable to wear. The flexible screen can effectively solve this problem. The curved surface fits more closely to the wrist radian, reducing discomfort, without losing the display area. You can have both fish and bear's paw. It is a little pity that most of these curved screen products are fixed angle and cannot be bent at will. However, with the progress of science and technology and the growing maturity of flexible circuit boards and flexible batteries, we believe that this day will not be too far away.
In addition to mobile phones and wearable devices, TV is another battlefield of flexible screens. LG and Samsung are almost in a battle. The curved screen TVs of LG and Samsung can be seen in almost every large-scale electronic exhibition. Compared with flat TV, curved TV can provide a larger viewing angle and a more realistic "embracing" sense of presence. In addition, curved TV is more in line with the characteristics of human visual structure, which can eliminate the visual distortion of the four edges of the screen and make the visual experience more comfortable.
Flexible screen has so many advantages and wide application space that its future is immeasurable. Although it is not possible to mass produce truly bendable products due to current technology, with the maturity of technology and the gradual reduction of cost, it is believed that in the near future, we can really roll up mobile phones and put them in our pockets.
