The technology in the mobile phone industry has been updated very quickly. For example, in terms of screens, major manufacturers have explored various forms of screens, such as slide screens, flip screens and folding screens ... Now, folding screens have fallen behind, and scroll screens are the outlet!
compared with the folding screen, which can't be completely eliminated at present, the scroll screen has no such problem at all, and the scroll screen will have more advantages in the size of the mobile phone, so from the perspective of the future mobile phone design, the scroll will be more in line with the characteristics of the times, but it is too difficult to achieve mass production now.
Next, let's take a look at which manufacturers have "painted cakes" scroll screens, and what are their differences?
OPPO: the first scroll screen concept machine
at the future science and technology conference last year, OPPO brought an OPPO X 221 scroll screen concept machine, which adopted an OLED screen with a maximum size of 7.4 inches and a minimum size of 6.7 inches, achieving almost "zero crease" screen effect, 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 the scroll screen, realizing the integrated and extended screen layout, ensuring the thickness of the fuselage, the service life of the screen, the durability and so on. It is said that OPPO is likely to release a scroll screen mobile phone in the new product launch conference held on December 14th!
vivo: the patent exposure of scroll screen technology
followed closely, and vivo also entered the game! Recently, a technical patent on vivo scroll screen was exposed on the external network, which was officially made public on December 2 this year. It is mentioned in the patent that a scroll is built in 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 OPPO's previous scroll screen mobile phone.
it is worth mentioning that the patent mentions that the front of the vivo scroll screen adopts the design scheme of digging holes in the upper right corner, and there are three cameras arranged vertically on the back, instead of using the front screen scheme like the Samsung Galaxy Fold 3. Foreign media speculated that the new scroll screen of vivo will be officially unveiled next year, and then it depends on which of OPPO and vivo can take the lead in commercializing the scroll screen. Perhaps it is not impossible to kill a new mobile phone manufacturer to cut off the first scroll screen halfway.
Xiaomi: The patent exposure of Xiaomi scroll screen mobile phone
In fact, as early as 219, Xiaomi exposed the patent of scroll screen mobile phone.
according to news from foreign media LetsGoDigital, at the end of 219, Xiaomi applied to USPTO (United States Patent and Trademark Office) for the patent of "terminal equipment with flexible screen", which was approved on October 29, 219 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, a concept machine of surround screen previously shown by Xiaomi, but the difference is that the screen extension width of this mobile phone can reach 2%, and the screen size can be automatically adjusted according to the displayed content. According to the structural drawing, 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 under the extrusion of external force. The button on the top of the mobile phone is the power switch, and also serves as the unlocking key for screen expansion. At present, there is no new news from Xiaomi scroll screen mobile phone. I don't know if it is brewing silently. Will it release a big move at that time?
In addition, although Xiaomi hasn't sent out relevant information, the screens of folding screens, off-screen front shots, tablets and other products previously 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 scroll screen mobile phones
In August, Huawei released a set of concept renderings of Mate series stretchable scroll screen mobile phones. It is estimated that Huawei also has plans on the scroll screen. It is understood that this scroll screen mobile phone has three ways to expand!
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 placed together, so that the display screen is laid flat on the device, and it looks wrinkle-free, regardless of whether the display screen is pulled out.
between the two magnets, a roller is placed, which can ensure a certain gap between the pull-out monitor and the magnets. In this way, unnecessary friction can be avoided.
this is a very detailed patent, and its main purpose is to prevent unnecessary screen folding. Another detail is disclosed, that is, the device will have three modes. You can pull out the screen a little, a little more, or not at all.
Samsung: patent exposure of scroll 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 222.
at present, Samsung has not officially launched the physical scroll screen, and the domestic screen has already taken the lead this time. Congratulations!
Huaxing Optoelectronics: scroll 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 expanded to the left in the unfolded state, which perfectly combines the characteristics of the scroll screen and the folding screen. This is the first screen scheme in the industry that combines the scroll screen and the folding screen into one!
At present, the folding screen mobile phone is mature, and the scroll screen is expected to be mass-produced and commercialized soon. The latter has wider practical value than the folding screen, and the scroll screen has no creases. At present, the scheme is still in the prototype stage, and it may take a long time before mass production. It is reported that Huaxing photoelectric scroll screen scheme has been sent to manufacturers for testing, and it is likely that it will be mass-produced and commercialized in 222!
who do you think will be the first person to eat crabs?
