The most popular folding screen has different desi

  • Detail

Folding screen design ideas are different, and there are so many patterns before it is launched.

before entering the intelligent era, we can see a very rich design style. According to the presentation effect, it can be roughly divided into four categories: straight screen, flip (fold), slide and rotate, mainly to make the layout of the screen and physical keyboard more innovative. When the physical keyboard is no longer required for interaction, and all operations can be realized through a touch screen, the ID design of has converged year by year, and gradually lacks features and new ideas

at present, the development direction of the industry is to make the screen as large as possible and keep the body size in a state that can be held by one hand. In order to increase the proportion of screens, manufacturers have made great efforts. The proportion of screens has increased from 16:9 to 18:9 and 19.5:9. This is not the end. Sony recently exposed a 21:9 ratio, which fully proves that the longer and longer ratio has gradually become a trend. The constant pursuit of large screen also gave birth to solutions such as bangs screen, water drop screen and perforated screen, which only retain some sensors on the screen. Mechanical structure and sliding cover structure have also re entered our vision

▼ from folding to folding screen

with the gradual maturity of upstream supply chain technology, there is another familiar solution for us to be reborn, that is folding. In our early years, the folding was to fold the screen and keyboard together through the rotating shaft, so as to hide the main screen and keyboard area. After the physical keyboard is replaced by the touch screen, this scheme turns the larger screen to be bent, so that the device can have two display sizes to meet different scenarios. Although the folding screen device has not been officially released for commercial use, there have been several distinctive concept products at the current concept stage. Let's have a look

▼ Samsung - folding screen prototype

Samsung showed a folding screen prototype at the press conference earlier, which is designed with a small screen and a folding screen. In the closed state, the normal operation can be realized through the small screen. When fully expanded, you can get a 7.3-inch screen, which changes to a tablet device in seconds. This is very similar to the folding in earlier years. It just extends the screen to the physical keyboard position. After closing, the external small screen is also the same as the secondary screen of the flip

– technical implementation principle:

Samsung uses its own AMOLED screen in this equipment manufacturer. The OLED screen is different from the LCD screen with backlight layer and liquid crystal layer. It can achieve large bending and use more superior cop packaging process. The screen backplane changes from glass to flexible material, so that the chip can be bent and folded. It is applied to the folding screen to achieve the effect of 1 + 1> 2. It can not only bend at will, but also achieve a more extreme narrow border effect

Samsung submitted a folding design patent in August 2017. The leading design patent increases the bending degree of OLED screen in order to realize the flatness of the folded fuselage. A large circular arc is formed inside the screen at the rotating shaft to protect the screen from being damaged due to excessive bending. This solution is likely to be applied to inward folding devices, which can maximize the protection of the screen from damage due to excessive bending, and also keep the folded fuselage horizontal

▼ Xiaomi - double folding

Xiaomi also officially exposed its own folding screen device. He said that he has conquered the flexible folding screen technology and flexible cover technology. This device adopts the 4WD folding shaft technology to realize folding, and is successfully adapted to the MIUI system, which can switch between and tablet experience

from the video, we can see that this model is very different from the prototype concept of Samsung. Samsung has two screens. The main screen is folded in half, and the screen is clamped in the middle to be protected. Both sides of Xiaomi double fold can be bent, and the turning direction is opposite to that of Samsung

this model looks like a small flat plate when fully deployed. The screen area on the left and right sides is half of that of the middle screen. Turning back just meets the center line behind, it becomes a circular screen

according to the known technology, Xiaomi uses the flexible foldable panel realized by OLED screen. Compared with Samsung's inner folding screen, the inner folding needs to consider the maximum bending curvature of the screen, and the outer bending does not need to consider this because of the thickness limit of the fuselage. There is no need to consider the screen bending limit, which is relatively easy

the mechanical structure can also be realized through hinges, which is generally similar to the hinge design of surface series, but it needs a lot of effort to achieve a better fit to the fuselage after bending

there are also several folding screen devices that have exposed information and patents/design drawings, but have not exposed the real machine. The design ideas are different and very interesting

▼ Motorola - Razr reprint

razr V3 is a leading ultra-thin product launched by Motorola in 2004, with a thickness of only 13.9mm. The fuselage adopts aviation aluminum alloy shell, which can better protect internal components. After opening the keyboard, the laser carving process is used, which adds a lot of points to the overall design. With the light and thin fuselage, the pursuit of ultra-thin design can be more realized when the screen is opened. The design is a generation of classics

the folding screen is somewhat similar to the flip. Now it is not only similar. According to the latest information, moto will release a replica that retains the Razr design language. This Razr replica with folding screen directly extends the original main screen down to the bottom of the physical keyboard area, and you can get a whole screen by expanding it. The bottom and back of the fuselage still retain the iconic design of Razr

▼ LG - "scroll" patent

now more flexible screens are applied to surface design, and folding screens only need one area to fold. LG's patented design is very interesting. It gives full play to the characteristics of flexible screen. The device is fully stowed in two parts. One end is the main body for storing the screen, and the back is the conventional experimental volume key and power key that are not easy to choose as plastic materials. The small screen on the front displays the notification and power icon in the status bar. The other end has a function key, which may be used to realize fingerprint recognition. To make such materials into solid parts by horizontal pulling on both sides, a large pressurized furnace is used to pull the screen out of the main body like a scroll, and the displayed content will change with the size of the screen

▼ apple - two way folding patent

apple is not so radical in the use of new technologies. It always comes up with the best and safe solutions directly after the technology is mature to make friends have difficulties. The two real machines that have been shown above and the two concept products that have no messages adopt the one-way folding scheme. An Apple patent shows that its folding device can realize forward and reverse folding. This has two advantages. The inner fold can protect the screen more fully when not in use. During normal use, the external folding can reduce the volume of the equipment by half, which is more suitable for ② forming a deep interface dispersion and mechanical interlocking single hand operation at the interface. It is an ideal solution

▼ summary:

we can see two ideas, Zoom in and "Zoom out". Through the expandable folding screen technology, you can obtain a larger screen and a wider display field. It not only meets the portability of the, but also meets the needs of users for a large screen. It is very suitable for going out to watch movies and play games. The tablet is two in one. After the initial introduction of the folding screen device, how to reduce the thickness from one system to another will be a major problem faced by manufacturers.

zoom out through the folding screen The existing fuselage size is also a good design idea. At present, both Samsung and Xiaomi display folding screen products, which stretch a conventional size into a larger size tablet device. For the current 6-inch or 7-inch devices, they can actually meet the entertainment needs of ordinary users. Folding the vertical screen into a more portable device is also a good choice

with the approach of MWC 2019, it is believed that more folding screen devices will meet us. It is expected that as in the era of functional machines, hundreds of flowers will bloom, and each manufacturer will bring more suitable products to users according to its own style and characteristics
