Compared with the folding screen, which can not be completely eliminated at present, the scrolling screen has no such problem at all, and the scrolling screen will have an advantage in the size of the mobile phone. So from the perspective of future mobile phone design, the scroll will be more in line with the progress of the times, but it is too difficult to achieve mass production now.
Below, let's take a look at which manufacturers have "painted cakes" scroll screens. What's their difference?
OPPO: the first scrolling screen concept machine
At last year's Future Science and Technology Conference, OPPO brought an OPPO X 202 1 scrolling screen concept machine, which adopted an organic light-emitting diode screen with a maximum size of 7.4 inches and a minimum size of 6.7 inches, achieving a screen effect of almost "zero crease", breaking the traditional folding screen shape design and guiding a new direction for the final shape development of mobile phones.
PPO has invested a lot of research and development in the process of realizing scrolling screen, realizing an integrated and expanded screen layout, ensuring the thickness of the fuselage, the service life and durability of the display screen. It is said that OPPO will probably release a scroll phone at the new product launch conference held in February 14, 65438!
Vivo: patent exposure of scrolling screen technology
Followed by vivo! Recently, a technical patent of vivo scrolling screen was exposed on the external network, which was officially made public at 65438 on February 2 this year. It is mentioned in the patent that a scroll is built into the left side of the fuselage, which can enlarge the screen from left to right and become a size similar to the screen size of a tablet computer. This screen design method is very similar to the scroll screen phone before OPPO.
It is worth mentioning that the patent mentioned that the front of vivo scroll screen adopts the design scheme of digging holes in the upper right corner, and there are three vertically arranged cameras on the back, instead of adopting the front screen scheme like Samsung Galaxy Fold 3. Foreign media speculated that vivo, a brand-new screen winder, will be officially unveiled next year. At that time, we will see who can take the lead in commercializing the scrolling screen between OPPO and vivo. Perhaps it is not impossible to kill a new mobile phone manufacturer halfway to cut Hu's first scrolling screen.
Xiaomi: Xiaomi scrolling screen mobile phone patent exposure
In fact, as early as 20 19, Xiaomi exposed the patent of scrolling mobile phone.
According to the news of foreign media LetsGoDigital, at the end of 20 19, Xiaomi applied to USPTO (United States Patent and Trademark Office) for the patent of "flexible screen terminal equipment", which was approved on 20 19129 and published in WIPO (World Intellectual Property Office) database.
As can be seen from the renderings designed by foreign designers according to patents, this mobile phone is similar to Xiaomi MIX Alpha, the concept machine of surround screen that Xiaomi showed before. The difference is that the screen extension width of this machine can reach 200%, and the screen size can be automatically adjusted according to the displayed content. According to the structural diagram, it can be found that two foldable support structures are added inside the fuselage, which can ensure that there will be no obvious creases when the screen expands and contracts.
At the same time, the supporting structure can also protect the screen from deformation when it is squeezed by external force. The key on the top of the mobile phone is the power switch, and also serves as the unlock key for screen expansion. At present, there is no new news on Xiaomi scroll screen mobile phone. I don't know if it is brewing silently. Will there be a big move then?
In addition, although Xiaomi has not yet sent out relevant information, the screens of products such as folding screens, off-screen front positions and tablets released by Xiaomi are all supplied by Huaxing. If Huaxing produces scroll screens, Xiaomi should also use them!
Huawei: concept renderings of Mate series stretchable scrolling screen mobile phones.
In August, Huawei released a set of concept renderings of Mate series stretchable scrolling mobile phones. It is estimated that Huawei also has plans to scroll the screen. It is understood that this scrolling mobile phone has three expansion methods!
When the retractable screen is pulled out, the screen will be deformed because the screen is rolled out along the side of the device. In order to prevent the screen from wrinkling, two magnets are put together, so that the display screen is flat on the device. No matter whether the display screen is pulled out or not, it looks wrinkle-free.
Placing a roller between two magnets can ensure a certain gap between the pull-out display and the magnets. This can avoid unnecessary friction.
This is a very detailed patent, the main purpose of which is to prevent unnecessary screen folding. Another detail is disclosed, that is, the device will have three modes. You can pull the screen out a little, a little more, or you can not pull it.
Samsung: patent exposure of scrolling screen
In June this year, Samsung's scroll screen patent was exposed. It is understood that this mobile phone uses off-screen camera technology and may be released in the first half of 2022.
At present, Samsung has not officially launched a physical scrolling screen, and the domestic screen has taken the lead this time. Congratulations!
Huaxing Optoelectronic: Roll Screen+Folding Screen in One
I don't know who was the first person to eat crabs, but the biggest winner is probably Huaxing Optoelectronics.
Just today, Huaxing Optoelectronics exposed a prototype! The machine can be folded, and the screen can be unfolded to the left in the unfolded state, which perfectly combines the characteristics of scrolling screen and folding screen. This is the first screen scheme in the industry that combines scrolling screen and folding screen!
At present, the folding screen mobile phone is mature, and the scrolling screen is expected to be mass-produced and commercialized soon. The latter has wider practical value than the folding screen, and the scrolling screen has no crease. At present, the scheme is still in the prototype stage, and it may take a long time for mass production. It is reported that Huaxing photoelectric screen rolling scheme has been sent to the manufacturer for testing, and it is likely to be mass-produced and commercialized in 2022!
Who do you think will eat crabs first?
