Besides cool, is collapsible just a big screen

now, as the hole digging screen begins to enter the research and development sequence of large manufacturers, the major companies are moving towards the ultimate shape of a complete comprehensive screen, which seems to have taken another step towards their good combination with the polymer matrix, and these are also working towards 100% of the screen share. However, no matter how this comprehensive screen evolves, what we finally see is still a traditional straight board, and there is no revolutionary change in the use of logic or operation, And these ultimate comprehensive screens only make the straight board to the extreme

if you want to make another breakthrough in the bottleneck, self linearity naturally needs to be amazing in the means of operation, and folding screen seems to be a new development direction in the future. However, folding, which looks very cool outside, still needs very advanced and rigorous technology to realize. Compared with the straight board, what are the technical difficulties of the foldable flexible screen and how is it different from the ordinary large screen

first, folding screen, screen is the key

as an important technical difficulty of folding screen, the screen is the top priority of the whole, and the bending degree of the screen determines the quality of folding. As the two most mainstream screens at present, OLED and LCD have different feasibility of using folding

first of all, LCD and OLED are very different in light-emitting principle and structural characteristics. The LCD structure is to place a liquid crystal cell between two parallel glass substrates, a thin-film transistor is set on the lower substrate glass, and a color filter is set on the upper substrate glass. The rotation direction of liquid crystal molecules is controlled by changing the signal and voltage on the TFT, so as to control whether polarized light is emitted from each pixel and achieve the display purpose. OLED makes every RGB pixel self luminous, which is much thinner than LCD

for the folding screen, the screen needs to be bent, and the LCD has a backlight layer and a liquid crystal layer, so the material cannot be bent greatly, while the OLED can be bent greatly, even circled like paper, which provides a technical guarantee for the realization of the folding screen. Therefore, the folding that has been shown at present adopts the material of OLED

after the folding of the screen technology is realized, how to fold the screen without displaying hinges and other factors affecting the appearance has become the next difficulty that manufacturers need to overcome. The giant Samsung gave a solution about screen folding

the folding design patent submitted by Samsung in August 2017 reveals how Samsung realizes the folding of the screen. Samsung claims that they have increased the bending degree of the OLED screen, so that the screen can form a large arc inside the rotating shaft to protect the screen from being damaged by excessive bending, so as to realize the folding of the screen. At present, Samsung has shown the galaxy F, which is expected to adopt this principle

▲ LG exposed the folding screen patent

and the domestic technology manufacturer Ruoyu technology also launched its own foldable flexible screen, which is also the world's first foldable flexible screen. In terms of parameters, roupai is equipped with a 7.8-inch cicada wing flexible screen of generation 2, with a resolution of 1920 × 1440 (unfolded state), which can be folded to an ordinary size of only 4.0 inches in daily use, and the thickness of the fuselage is 7.6mm; At the same time, it has more than 200000 bending operations in terms of durability, and because of the characteristics of the flexible screen, it will not break the screen in the future. From the rendered image, roupai adopts a hinged design, which also increases the overall thickness of the

through the stacking of screens, the folding screen can make the screen larger when the surface area remains unchanged. For example, the softpie above can rely on a 4.0-size screen to achieve a 7.8-inch screen, which is also a good way to increase the display area when the surface area is at its limit

second, UI compatibility is equally important

as mentioned many times in the previous article of it home on folding, the introduction of folding screen requires not only the implementation of hardware, but also the corresponding software. For example, using a special UI or system, for example, Samsung released one UI specially adapted for folding screen. Samsung one UI threw away the bar frame design, greatly reduced the decoration in detail in the design, and the icon is more flat, The way of presenting information is more concise and clear

obviously, Samsung has begun to make software preparations for Galaxy F. at the same time, in addition to the native apps, third-party apps also need to be specially optimized for these folding screens. On CES 2019, foreign media also experienced softschool, and said that most software functions of softschool still have many problems, and there are quite a lot of bugs in the use experience, Obviously, in terms of software experience, folding screen needs more software optimization

summary, folding screen is equivalent to large screen

obviously, the fundamental purpose of folding screen is to increase the screen area that is difficult to increase at present, so as to change users' habits. Of course, basically speaking, the folding screen has a huge screen. When it is fully expanded, the screen area can be fastened in time with the tablet computer; Mention and discuss, which will lead to the antipathy of anti big screen people

no matter from the display effect or the use logic, the small screen will not occupy the mainstream position in the folding screen. Naturally, for consumers who are insensitive to the large screen, the future foldable flexible screen may be your dish, but it must be admitted that when the large screen ravages the whole manufacturer, the small and refined living space is getting smaller and smaller
