In the past two years, mentioning "full screen" can always be associated with "Liu Haier". Objectively speaking, Liu Haiping was indeed a good solution for a full-screen mobile phone at that time, and there would always be sacrifices in removing the forehead. Today, with the emergence of under-screen fingerprint technology and the hidden design of the earpiece, the full-screen technology is becoming more and more mature. Therefore, we are gradually turning our attention to the under-screen camera technology.
In order to achieve a higher screen-to-body ratio, pop-up designs and slider phones with more complex frames are a solution. However, the use of the sliding cover form will inevitably make the overall body of the mobile phone thicker, sacrifice the quality of the camera, sacrifice a certain amount of heat dissipation for dust prevention, and the sliding cover structure occupies the space that the body does not have ample space.

The under-screen camera technology is the ultimate solution for a true full-screen display. For this technology, many brand manufacturers have started research and development in the past few years, and some research and development results have even been quite mature, close to the mass production level.
Sony provides technology, Samsung provides screen to jointly develop under-screen camera
As early as February 2018, it was reported that Samsung and Sony had abandoned the bezel camera module. And some industry insiders broke the news that Samsung and Sony have begun to cooperate in the development of under-screen camera technology based on their existing technologies.

According to digital expert Onitsuka__8M, the future under-screen fingerprint technology will rely on Samsung's OLED screen, because OLED screen has an excellent transparent substrate, which is very suitable for under-screen camera solutions. In addition to Sony's own under-screen camera solution, the cooperation between the two giants is a powerful combination, which is a must.

Judging from the pictures exposed above, the under-screen camera solution adopted by Sony does not seem to abandon the Home button, and the positions of components such as the camera above have not changed much from traditional full-screen mobile phones. It seems that this solution is completely satisfactory. Benefiting from the transparency of the "screen", it seems that a display sheet is used to cover the top of the mobile phone, and this sheet can not only display the color, but also has a "penetrating" effect on the Home button and the camera element, which is definitely called Modern black technology.
Samsung refuses to "squeeze toothpaste", the prototype of the camera under the screen has been made
News on November 11, as the overlord of the Android mobile phone market, Samsung's flagship products are full of various black technologies every year, especially in terms of screen display, which is ahead of most mobile phone manufacturers in the industry. According to reports, Samsung's next-generation flagship product, the S10, will be equipped with under-screen fingerprint recognition, and the screen-to-body ratio will be further improved.
It is reported that the Samsung S10 will have three versions, of which the standard version is code-named "Beyond", equipped with a rounded curved screen, the upper and lower borders are very narrow, and the screen ratio is further improved compared to the S9. In terms of size, the Samsung S10 and S9 are roughly the same, equipped with a 5.8-inch Infinity Display screen, but because the front camera is hidden under the screen, the screen ratio of the S10 will be higher, and it will look more like a real full-screen mobile phone.
In terms of performance, there is no doubt that the Samsung S10 will be equipped with the latest flagship products and will be equipped with three rear cameras. At the same time, it is reported that the Samsung S10 will also have a 5G version, but the details will not be known until the official announcement.
At the 2018 Samsung Developer Conference, in addition to showing its own folding screen mobile phone with Infinity Flex Display screen technology, Samsung also announced Infinity-U (water drop screen), Infinity-V (V-shaped groove) and Infinity-O (screen). Digging holes) and other three kinds of special-shaped screens.
Previously, many users praised Samsung for not adopting the special-shaped screen design, and Samsung also specially launched an advertisement mocking the design of Apple's special-shaped Liu Haiping. However, under the leadership of Apple, almost all other Android manufacturers, including Google's "pro son", have adopted the special-shaped screen design, and Samsung's use of the special-shaped screen design seems to be irresistible. The details of Samsung's three special-shaped screens are as follows:
Infinity U: It is almost identical to the bangs design of the Essential Phone, that is, the "water drop screen" familiar to domestic users;
Infinity V: Similar to Infinity U, but its square is a sharp corner;
Infinity O: There will be a full circular cutout on the display instead of a "notch" on the top edge of the screen.
As an important screen manufacturer, Samsung only sold special-shaped screens to the outside world and did not use it in its own products. After the "panoramic curved screen" of the Galaxy S8 / S9 and Note 8 / 9, according to the previous warm-up, the first model of Samsung's special-shaped screen is expected to be the Galaxy A8s.
Huawei: Realize 100% Full Screen hidden camera technology
The main difficulty in achieving a 100% full screen is how to layout the front camera and earpiece. Previously, media reports said that Huawei applied for a color-changing glass patent to realize the under-screen camera solution, and now, a new earpiece solution has also surfaced. The market speculates that these two new patents may be used in Huawei's 5G mobile phone next year.

Dimming glass is also called fogging glass. Dimming glass is a kind of intelligent high-grade functional glass. The dimming glass is controlled by voltage to change between scattering (transparent opaque) state and transmission (transparent) state. This change realizes the dual requirements of glass permeability and privacy protection. This glass back is widely used in hotel bathrooms, high-end offices, computer rooms, medical institutions, etc., and is usually used to prevent peeping. According to NTNews, Huawei makes the screen transparent and back to color. This is indeed similar to the color tinting glass. If Huawei applies the color tinting glass technology to mobile phones, it will make people fall into infinite reverie and look forward to it. .
It is understood that Huawei has adopted a screen hole-type handset, which is very different. Previously, some manufacturers were using the screen sound technology to remove the earpiece. I don't know why Huawei insisted on keeping it, and had to dig grooves in the screen.
In addition, according to foreign media Phone Arena, the patent for Huawei's under-screen camera has also surfaced recently. From the outflow of the patent image, although the front camera is hidden, there is still a "strip hole" part that cannot be hidden. , Phone Arena believes that the "bar hole" not only inherits the earpiece, but the front camera and the required sensors are actually hidden in this place.
It is worth mentioning that the USPTO announced the patent draft of the handset solution submitted by Huawei on November 6, and the first application date can be traced back to September 2, 2016. In addition, the phone in the patent uses a fingerprint on the back, a 3.5mm headphone jack on the top, and a USB-C port on the bottom. It is not known which phone it can correspond to.
Although everyone knows that the shape of Liu Haiping and special-shaped screen will not be the end of the smart phone, but no one can give the exact 100% full screen time. In the transition, designs such as slide covers and pop-up lenses have emerged. However, such designs are questioned that the photographic quality will be affected.
Once Huawei realizes the hiding of the front camera, it will undoubtedly be a step forward from the beautiful screen. However, it is expected that Huawei will have to wait until June next year at the earliest to come up with this technology on the flagship machine.
Considering that Huawei's rotating chairman Xu Zhijun and Huawei's consumer business CEO Yu Chengdong have said in public that Huawei's first 5G mobile phone will be released in June 2019, the market speculates that "under-screen camera technology", "screen-digging earpieces" "It may appear on this phone at the earliest.
LG files patent for smartphone with under-screen camera, bezel-less 100% full-screen smartphone

LG has recently filed a number of patent applications for future smartphones, which will have almost 100 percent screen-to-body ratio and be completely bezel-less. From the content of these patents, the only thing on the front of the screen that is not part of the display area is the small cutout for the front camera.
These patents, filed by LG with South Korea's local Intellectual Property Office, basically show two different smartphone full-screen designs. The first, pictured above, is a "solid" phone in the style of the iPhone 5, with rounded corners and a bezel-less design.
The second has a similar full-screen design to the first, except that the right side of the screen is slightly curved to create a sort of bezel with tapered sides.
Both models are full-screen smartphones with flexible displays. Considering that OLED is one of LG's major developmental display technologies, this phone design is likely to use an OLED screen.
These patent applications were analyzed and reported by LetsGoDigital and published on October 24 and November 2 this year, respectively, so they may have been filed for months or even a year or so. Among the designs proposed in these patents, the placement of the in-screen front-facing camera is the only visible difference.
The oval cutout above the phone is a feature of its design. LG Electronics explained in the patent document that the upper end adopts an oval transparent display, which can realize a full-screen display or use a hole in the panel to realize a full-screen design by building a camera.
The patents applied for by LG Electronics are expected to be used in future smartphones. The commercialization schedule is still unknown, but this shows that LG is actively participating in the hottest field of smartphones at present - high screen ratio full screen and screen. The design of the study under the camera.
vivo has opened two small holes on the phone and the rest of the sensors are minimalist
When it comes to the minimalist sensor processing solution, vivo has the most say, because this year's vivo NEX has such a design. In addition to the use of hidden sensors in vivo NEX, the earpiece design of vivo NEX has also been cancelled, and replaced by the screen speaker function. With the sensors and earpieces out of the way, the remaining conundrum is the front-facing camera.

In fact, as early as March 2018, vivo began to study the under-screen camera technology, and handed over the task of the screen to Samsung. In May 2018, Samsung had already produced a small number of screens that can support under-screen camera technology. This type of screen can not only ensure the normal display effect, but also ensure the light transmission effect of the camera, which is equivalent to the aperture camera in effect.

Recently, a set of spy photos of vivo Xplay 7 were exposed on major dating platforms, not only with off-screen cameras, but also on-screen fingerprint technology and facial recognition. It is said that the running memory has exceeded 10GB.

Judging from the pictures, vivo Xplay 7 does cleverly hide the front camera in the screen. When the screen is fully lit, the picture is hardly affected. The actual experience will have to wait for the real machine to be released before revealing the answer.
