Full screen mobile phone is the inevitable trend of mobile phone development in the future. It has been two years since Xiaomi mix launched in 2016 to popularize the concept of full screen. Sigmaintell predicts that the shipment of full screen mobile phones will reach 910million in 2018, and the penetration rate of full screen products in the smart phone market will reach 61%. Full screen mobile phones have evolved from the conservative “18:9” era to the current “full screen +” era.

There are four major problems in the initial stage of comprehensive screen development

“The trend of the times is vast, and those who follow it will prosper, while those who go against it will perish.” the comprehensive screen is the general trend of the development of smart phones. It brings users a more shocking visual experience with a very high proportion of screens, and can also effectively control the growth of mobile phone size. Although the general full screen mobile phone is the inevitable trend of mobile phone development, it is still in the stage of concept popularization. Therefore, there are still the following four problems in the development of the general full screen mobile phone.

First, the user experience is poor. Full screen mobile phones have to face the eternal paradox of “you can’t have both fish and bear’s paw”. While pursuing a higher proportion of screens, you must compromise the user experience. If we want to achieve a truly comprehensive screen, the essential front camera, fingerprint identification module and earpiece of smart phones cannot have a foothold, even in the initial stage of a comprehensive screen. For example, in order to achieve a comprehensive screen, Xiaomi mix replaced the earpiece with bone conduction, moved the camera to the lower end of the mobile phone, and put the fingerprint module on the back. However, the result is that the earpiece sound is too low, it is inconvenient to take photos in front, and the back of the mobile phone is not integrated, which reduces the user’s experience.

Second, the screen share is still not high. The concept of full screen mobile phone originates from Chinese mobile phone manufacturers. As the name suggests, it refers to mobile phones with 100% of mobile phone screens, but it is almost impossible to achieve it with the current technical level. Therefore, mobile phone manufacturers call mobile phones with 18:9 screens and more than 80% of screens as full screen phones in the primary stage of full screen. According to the data of China industry information network, the average proportion of mainstream full screen mobile phone screens in the market in 2017 was 83%, only about 10% higher than the proportion of non full screen mobile phone screens in 2016. The actual increase is not obvious, and the proportion of screens is still not high.

Third, the screen touch error rate is high. The increase of the screen share is inseparable from the reduction of the border around the mobile phone, and the continuous reduction of the border of the mobile phone will inevitably lead to the problem of screen MIS touch. For example, the page is turned before you finish reading, and you suddenly pause or quit while watching a movie. These small problems together become a big problem that hinders the user experience.

Fourth, the screen is fragile and difficult to repair. The original intention of the full screen is to achieve 100% of the mobile phone screen. At present, although it can not achieve 100%, it is also working towards a nearly 100% screen share. The frame around the mobile phone naturally narrows, but it also means that the protection of the mobile phone frame to the screen is relatively reduced, increasing the risk of broken screen of the full screen mobile phone. Moreover, due to the particularity of full screen packaging, the difficulty of mobile phone maintenance is also increasing. For example, the essential phone, which is designed by the father of Android and adopts the beauty tip, has been rated as the most difficult phone to repair by the world-famous dismantlement agency. It can be seen that the maintenance of the full screen mobile phone is very difficult.

Lack of software and hardware technology leads to congenital deficiency of comprehensive screen

Some people are born to be kings, while others become bandits. However, since the day of the birth of the full screen mobile phone, there has been a congenital deficiency. In the final analysis, it is caused by the immaturity of technology, and it is the result of the joint action of hardware technology and software technology defects.

In terms of hardware, as the front camera, earpiece and various sensors are now the essential functional modules of smart phones, which need to occupy part of the front panel of mobile phones, the proportion of full screen mobile phone screens in the initial stage is still not high.

In terms of software, the overall screen mobile phone software adaptation is not ideal, the daily software display lacks weight and the video display has large black edges. At present, the software developed by most developers has not been optimized for full screen mobile phones, and even the official system has not optimized all scenarios in the system, resulting in abnormal display of full screen mobile phones in most application scenarios. For example, playing the famous “wangzherongyao” with iPhone x will also cause the display content to be partially blocked by Qi bangs, seriously affecting the user’s game experience.

The existence of black edges in video display is due to the screen ratio of full screen mobile phones is 18:9, the ratio of movies is 16:9, and the ratio of TV dramas is 4:3. Therefore, no matter what video you watch with a full screen mobile phone, there will be wide black edges around. If you force the full screen, the video picture will be seriously deformed, affecting the viewing experience of users.

In addition, the narrower frame of the mobile phone makes the screen fragile and easy to touch. Although the frame wastes the limited space of the front panel and affects the beauty of the mobile phone, it has to be said that the mobile phone frame can effectively protect the screen and prevent accidental touch. The overall screen mobile phone frame becomes extremely narrow, which increases the probability of the mobile phone screen touching the ground on the one hand, and increases the probability of the mobile phone screen touching by mistake on the other hand.

Comprehensive screen “three families” have their own strengths and weaknesses

From the era of “18:9” two years ago to the era of “full screen +” today, the full screen solutions in the market are gradually enriched. From the first Samsung curved full screen to the imitation of Apple’s qiliuhai, then came the potential full screen used by oppo find x, vivo nex and glory magic 2. After updating and iterating, the full screen solutions in the market have emerged three liberation solutions. But who can lead the industry trend of full screen mobile phones with three full screen solutions?

Class I: surface full screen

The curved screen was born a year earlier than the full screen. Samsung released its first curved screen mobile phone, the Samsung S6 edge, as early as 2015, which amazed four seats. However, the full screen broke out completely in 2017, and Samsung had to join the army of full screen due to the impact of full screen mobile phones. Combined with its own advantages, it combined the curved screen with the 18:9 full screen to produce the first full screen mobile phone Samsung Noto 8.

The curved full screen mobile phone has the characteristics of high screen share, high color value and low production difficulty. The flexible curved screen of Samsung is used. The left and right screens are conducive to the refraction of light by the curved surface. There is almost no frame on the left and right sides visually. In addition, the upper and lower extremely narrow frames make the proportion of curved full screen mobile phone screen reach about 87%. In addition, the curved screen design has a better appearance experience. The left and right screen displays are extended to the side of the mobile phone, making the mobile phone more attractive. In addition, the production process of curved surface full screen is relatively mature, which not only has low production cost, but also has low production difficulty.

However, the curved full screen mobile phone looks more like an improved version of the ordinary 18:9 full screen mobile phone, which retains the basic appearance structure of the ordinary full screen mobile phone and is not very attractive to consumers. In addition, the fragility and touch error rate of the curved full screen mobile phone are higher than those of other full screen mobile phones. In contrast, the user experience is even worse than that of the ordinary 18:9 full screen mobile phone.

Class II: special shaped full screen

The introduction of the special-shaped full screen is the product of the compromise between the full screen mobile phone and the reality in the process of evolution. It was born in september2017. It is the mobile phone for the 10th anniversary of Apple mobile phone. Soon after its introduction, it has become the imitation object of major mobile phone manufacturers. The beauty tip and water drop screen design extended from the bang special-shaped design belong to the special-shaped full screen.

The special-shaped full screen has a higher screen share, which is generally distributed between 80% and 90%. Among them, the highest screen share of the special-shaped full screen mobile phones with meimeijian and shuidi screens can be as high as 90%, such as nut r2s, essential phone and oppo R17; In addition, the special-shaped full screen is better than the curved full screen in terms of fall resistance and anti touch. Although the frame is wider than the curved full screen, the special-shaped full screen makes use of more screen space, and can retain a reasonable frame to protect the screen and prevent screen fragmentation and MIS touch on the premise of increasing the screen proportion.

But no man is perfect, and no machine is perfect. In addition to the above advantages, the special-shaped comprehensive screen also has the following disadvantages: the display content of the special-shaped comprehensive screen is incomplete. For example, when the Xiaomi 8 Se used by the author plays games such as the glory of the king, it will be partially blocked, resulting in incomplete display. When watching videos, it will also have large black edges. Secondly, compared with other mobile phones in the “full screen +” era, the phones with special-shaped full screen have a lower appearance value. Many mobile phones with special-shaped full screen will lead to aesthetic fatigue of the public. Finally, the screen production cost and difficulty of irregular full screen mobile phones are high, and the price of mobile phones is more expensive than other mobile phones with the same performance.

Category III: periscope full screen

Periscope full screen is the latest product of full screen development. Not long ago, Huawei launched the glory Magic 2 in IFA, Germany, which is designed with a periscopic comprehensive screen. The screen proportion reached an unprecedented 95%, almost breaking through the limit of existing material science, becoming the most surprising egg in IFA exhibition. It has also been wildly praised by dozens of domestic and foreign media, saying that glory Magic 2 is a truly comprehensive screen mobile phone. Subsequently, Xiaomi Weibo said that Xiaomi mix 3, which will be released in October, will also adopt this design. It is worth noting that both vivo and oppo have launched comprehensive screen mobile phones with this design this year, which has been unanimously recognized by the outside world. The periscopic comprehensive screen design seems to have become a new favorite of smart phone manufacturers.

Periscope full screen mobile phones have an ultra-high proportion of screens. Oppo, vivo and glory’s three mobile phones with periscope full screen design account for more than 94%, which almost breaks through the limit of current human materials and takes a big step towards 100% full screen, almost calling it a true full screen.

Thanks to the periscopic full screen, the mobile phone cleverly hides the front camera inside the body, and automatically or manually pops up the camera when necessary. In addition, the periscopic full screen mobile phone also combines the earpiece with the sensor on the upper side of the fuselage, hardly occupying the front panel of the fuselage. In addition, the three mobile phones integrate the fingerprint identification module under the screen, which retains the integrity of the fuselage, so their appearance is generally high.

Due to the high degree of integration of the mobile phone, it is a combination of all avant-garde technologies. In addition, the current production technology is not mature. The periscopic full screen mobile phone still has problems such as high price, high production cost and difficulty, and large-scale mass production.

In a word, the periscopic full screen has a high degree of integration and a full sense of science and technology. It has basically achieved the true “full screen”, which is an excellent comprehensive screen solution at present; The irregular full screen mobile phone, although greatly increasing the screen share, destroys the integrity of the mobile phone screen content display, and the software adaptation is difficult, so it is not the best solution for the full screen; The curved full screen is more conventional, without obvious shortcomings and advantages, and it is not the solution of full screen. So to sum up, the periscopic full screen is a better full screen solution at present, and is likely to lead the new trend of the full screen mobile phone industry.
