Summary of New Mobile Technology Prospects In 2021: Traceless front Camera, Ultra Fast Charging and Lots More

2020 is destined to be an extraordinary year. Due to the epidemic, a large number of small and medium-sized enterprises are on the verge of bankruptcy. Consumers who feel the unemployment crisis are holding their pockets tightly, for fear that they will have no food tomorrow if they spend more money. Affected by this, the lives of various mobile phone manufacturers are equally difficult. This year was originally a year for the popularization of 5G technology. The prices of various products have risen to a greater or lesser extent. Coupled with the reduced consumer desire of users, the sales of flagship mobile phones are not good. As expected. Days are sad, but the technology of manufacturers is still improving. Notwithstanding, we have a handful of new mobile technology prospects In 2021.

With the gradual conclusion of the year-end new phone conferences of major mobile phone manufacturers this year, the mobile phone “war” in 2020 has come and gone.  We hope to see some “new things” to emerge.

In today’s smartphone market, due to the homogeneity of the basic configuration, manufacturers need to rack their brains to come up with some new selling points to better promote their flagship products.

Real fullscreen, super flash charge, high refresh rate, star diamond technology, micro-panel technology, almost every flagship mobile phone will bring some new technologies. This has to make users look forward to, what kind of changes will appear in the smartphone market next year, and perhaps what new experience it can bring us?

Summary of New Mobile Technology Prospects In 2021

Today, let us look forward to the future, from the current development trend of the mobile phone industry, predict what new technologies will be brought about by mobile phone development next year.

LTPO Adaptive Refresh Rate on OLED Screens

To be honest, OLED screens on mobile phones are no longer new, and the high refresh rate seems to have become the standard level for most smartphones, but the battery life problem brought by the high refresh rate of OLED screens seems to have not been solved until the LTPO technology emergence of OLED screens.

To put it simply, traditional OLED screens use LTPS technology. When the OLED pixels emit light, electrons need to pass through the crystal light of the display panel to stimulate the pixels to emit light. At the moment when the screen PPI is gradually increasing, manufacturers need to compress the size of the transistor, and the smaller the transistor makes the “resistance” of a single transistor increase, which will cause the power consumption of the screen to double.

The LTPO technology (low-temperature polycrystalline oxide) adds an oxide layer on the basis of LTPS. This oxide layer allows electrons to pass through the transistor faster and better, reducing the energy consumption required to activate the pixels, thereby reducing The power consumption of the screen display, the low-power screen technology reduces the consumption to as low as 1Hz, which in turn,  gives the mobile phone better battery life.

In theory, this technology can significantly reduce the power consumption of the screen display. According to actual measurement, the Apple Watch Series 4 with LTPO screen has better battery life when the screen is 30% larger than Apple Watch Series 3 and the battery is 30% smaller. For products that do not perform well in battery life, LTPO OLED is particularly important.

At present, only Samsung Galaxy Note20 Ultra uses LTPO technology on the market, and its display performance is 16% higher than that of the previous generation product. When equipped with a 120Hz high refresh screen, it has better power consumption performance. According to the news, we are likely to see this screen on iPhone 13 next year, and Vivo, which has a close relationship with Samsung, may also use this technology, which is really exciting.

120W Wired Flash Charging/80W Wireless Fast Charging

After all, mobile phones are portable mobile devices, so battery life has naturally become an eternal theme. Since 2013, we have experienced rapid charging technology innovation from 10W, 18W, 22.5W, 30W, 40W, 50W, 65W. Nowadays, wired fast charging technology up to 120W has been officially mass-produced. Although there are not many mobile phones with standard 120W fast charging technology, in 2021, more and more Android flagship phones will be upgraded to 120W Fast charge, which perfectly solves low battery anxiety.

In addition to wired flash-charging, wireless fast charging next year is also worth looking forward to. In the past, wireless charging was really not a very practical function. Although it can make you charge more convenient, the slower charging speed makes people more inclined to choose fast charging. Now, Xiaomi has announced the world’s first 80W wireless fast charge. It only takes 19 minutes to charge from 0 to 100%, which perfectly solves the problem of charging speed. Only for the first release of Xiaomi 11.

The Rear Dual Main Camera

More manufacturers have begun to specialize in mobile phone camera performance. Since 2018, many manufacturers have been promoting rear-mounted four-cameras. Sadly this kind of thing is more of a gimmick, and the extra 2 million pixels small lens is essentially a “make up”, Will does not have much impact on the phone camera performance.

Entering the second half of 2020, some manufacturers have begun to explore the image combination of rear dual main cameras, and achieve the effect of “less is more” through better photosensitive components, larger apertures, and better lens combinations. Judging from the current news, many manufacturers are preparing to follow up on this design this year. For example, the OPPO Find X3 series is expected to adopt a rear dual main camera design, that is, a wide-angle + ultra-wide-angle lens. Both cameras are IMX766 sensors (50 million pixels). , Image performance is expected to be further improved.

Under-Screen Cameras

Speaking of clichés, there seems to be no better match for this adjective than under-screen camera technology. Since 2018, the entire smartphone industry has been continuously searching for a true full screen. From Samsung’s upper and lower narrowing borders, Xiaomi’s front camera moved below the phone, to the full screen of the notch led by the iPhone X series, and then to the water drop screen, the digging screen and other special-shaped screens appear together, flip the camera, slide the camera, lift The true full screen of the camera is also imperfect.

It can be said that because of the existence of the front camera, the current full-screen designs on the market must have many drawbacks. If mobile phone manufacturers want to produce the ideal full-screen design, they must solve the technical problem of the camera. If you want to achieve a true full-screen design change, then the under-screen camera technology is essential.

In August of this year, the veteran domestic manufacturer ZTE released the ZTE A20 5G, which is also the world’s first smartphone with an under-screen camera. Subsequently, Xiaomi officially announced the third generation of under-screen camera technology, marking the maturity of under-screen camera technology. Judging from the current news, as the supply chain matures, it is believed that a large wave of “true full-screen” mobile phones will be born this year(2021).

New Screen Form

In recent years, as folding screen technology has become increasingly mature, more and more folding screen mobile phones have appeared in the mobile market. The essence of these products is to achieve the effect of mobile phone/tablet integration, but because the screen yield is not high, the flexible glass is fragile, and the screen has creases and other defects, they have not reached the level expected by everyone. So in 2021, will there be a better screen form?

Judging from the current news, the scroll screen seems to be the closest option to the perfect answer. The nature of this screen also uses the characteristics of the OLED flexible panel but abandons the folding design, so there is no trouble with hinges and creases. The manufacturer will bend the flexible display screen around one side of the fuselage, and as long as the user slides, the built-in motor can pull the screen out to extend the mobile phone screen.

At the Future Technology Conference held this year, OPPO brought us the OPPO X 2021 scroll screen concept machine. The product uses a variable-size flexible screen, allowing the mobile phone screen to achieve horizontal expansion and contraction like a scroll, and officially announced that this concept of technology will be commercialized. In the next year, more manufacturers will try this new screen technology, and the scroll screen will allow mobile phones to open up more ways to play, which can further change the consumer experience.

Summary

If you start with Nokia’s products, smartphones have been available for more than a decade. It is the rapid advancement of science and technology that allows it to last forever and always maintain its market competitiveness. Nowadays, smartphones have become an indispensable item in our lives. We use them for communication, entertainment, and even office work. We naturally hope that it can go to the next level and serve mankind better.

Judging from the development trend of the mobile phone industry at this stage, 2021 will be a year when many technologies will be commercialized, such as under-screen camera technology, scroll screen technology, and under-LCD fingerprint technology are expected to enter the stage of mass production. Manufacturers also hope to sweep the market slump in 2020 with new flagship products. As we journey through 2021 it is expected that manufacturers can bring different changes to mobile phones in the coming days.
