This month, Vivo held this year's spring conference, bringing you its first folding screen mobile phone - Vivo X Fold. X Fold as a high-end folding screen mobile phone, for everyone to bring a lot of black technology configuration, in addition to more advanced hinges, more mature screens, more business functions, but also the world's first equipped with 3D ultrasound dual-screen fingerprint recognition technology, vivo X Fold in the hardware can be described as full of surprises.
Vivo's high-end flagship products have always adopted ultrasonic fingerprint recognition technology, which has higher security, faster unlocking speed and stronger resistance to environmental interference compared with our common optical fingerprint recognition. Nowadays, many folding screen products only retain the facial recognition unlock function and the side unlock function due to technical reasons, which lack convenience in daily use. So today, the author will take you to understand the vivo X Fold equipped with 3D ultrasonic fingerprint recognition technology, and unlock what new ways to play for everyone.
01 3D ultrasonic fingerprint recognition principle
Before I begin, I will take you to a brief understanding of what 3D ultrasonic fingerprint recognition is. Ultrasonic fingerprint recognition is based on the principle of drawing fingerprint sound waves based on pressure readings of the skin reflecting sound waves (the readings can reach the level of deep pores). Since ultrasonic fingerprint recognition draws out the three-dimensional details of the fingerprint, the technology can capture fingerprint features such as fingerprint ridges and sweat pores, and the fingerprint pattern drawn is more secure and accurate.
Principle of ultrasonic fingerprint recognition
Thanks to the penetrating nature of ultrasonic waves, it is not only possible to penetrate glass, stainless steel, sapphire or plastic products, but also to overcome the problem that traditional fingerprints cannot unlock the phone due to sweat, grease, and dirt. However, due to cost problems, 3D ultrasonic fingerprint recognition has not been well popularized and promoted, and for daily use, 3D ultrasonic fingerprint recognition has an absolute advantage in use and experience.
02 Application of 3D ultrasonic fingerprint recognition
Compared with the general equipment, the 3D ultrasonic dual-screen fingerprint recognition used by vivo X Fold has a richer functional experience, in order to better verify the advantages of ultrasonic dual-screen fingerprint recognition, we have also prepared a series of tests for vivo X Fold.
Single-screen recording, dual-screen unlocking
It may be in everyone's general impression that the fingerprint recorded on the outer screen can only provide the external screen to be used, and the fingerprint entered by the inner screen can only provide the inner screen unlock. However, vivo X Fold has achieved a double screen unlock function, everyone does not need to enter their fingerprints twice, and only needs one time to realize the dual screen unlock function.
Through the animation, it is not difficult to see that vivo X Fold is very fast in fingerprint entry, it only takes a few seconds to quickly capture your fingerprint details, and the performance of vivo X Fold when unlocking is also very excellent, the unlocking speed is very fast, the unlock accuracy is also very high, and there will be no unlocking errors.
Wet hand unlocking, convenient and fast
In everyone's daily use of the machine environment, it is difficult to avoid the situation of wet hands unlocking the mobile phone, even if you always pay attention to the washing of hands to wipe your hands clean, it is difficult to avoid the phenomenon of fogging up the temperature difference. So, when the mobile phone screen or hand has water, can the unlock performance of the 3D ultrasound dual-screen fingerprint be as fast as usual? We sprinkle water droplets on the screen to simulate wet hands.
Through testing, it is not difficult to see that the unlock speed and unlock accuracy of vivo X Fold in the wet screen state are very reliable. Even if the screen is sprinkled with a pool of water, it will not affect the normal unlocking of the mobile phone, which shows that the ultrasonic fingerprint unlock does not have strict requirements for the dryness of the fingers.
Unlock without light and not dazzling at night
When we use the traditional optical fingerprint to unlock the phone, due to technical reasons, the general fingerprint area will be very bright, when unlocking the phone at night, the glare emitted by the unlocking area will be very dazzling, but the 3D ultrasonic screen fingerprint recognition of vivo X Fold improves this phenomenon.
Through the GIF diagram, we can see that the vivo X Fold will not emit any light when unlocking, and even if the phone is unlocked at night, it will not be dazzling, which greatly improves the experience of using the machine.
Underlying optimization, one-click direct
Vivo X Fold adopts the very highly acclaimed OriginOS Ocean system, which can bring different experiences to everyone through the underlying optimization. We can achieve direct application, quick opening and other convenient operations in the unlocking process. In terms of my usage habits, I like to browse e-books in the subway, so I can add reading software to the convenient opening category and open the APP with one click.
The author has this to say:
In general, vivo X Fold has many advantages over competitors in screen fingerprint unlocking, thanks to vivo's accumulation and research and development of 3D ultrasonic technology over the years, in order to make the best use of this technology, for everyone to bring a different machine experience.
Although this time only brings you a one-way evaluation of the 3D ultrasonic screen fingerprint, I believe that you can see more advantages through the detailed design of the vivo X Fold. Vivo X Fold, as vivo's first folding screen mobile phone, is a good start, with enough product strength to play very well. At present, masks have become the norm of our daily lives, fingerprint recognition function for everyone to bring convenience experience, I believe that everyone has more experience, in the long run, fingerprints will not change over time, in terms of security also has a natural advantage, so in general vivo X Fold is a very attentive product.
