Since the iPhone 5S first introduced fingerprint recognition, fingerprint recognition has gradually become the standard product of smart phones. However, with the advent of the era of full screen, the increasing proportion of screen makes it impossible to put the fingerprint identification module on the front of the mobile phone. Therefore, some mobile phones choose to put the fingerprint identification module on the side or back of the fuselage, but these schemes sacrifice convenience to a certain extent. In order to have a higher screen share without sacrificing the convenience of fingerprint identification, vivo took the lead in making a technological breakthrough, became the first mobile phone brand to launch screen fingerprint technology, and continued to research, develop and promote the development of screen fingerprint. Therefore, screen fingerprint is not only easier to use, but also popularized in a large area.

Vivo has an absolute say in the development of screen fingerprints. In the early stage, it even promoted the development of the whole industry on its own. As early as 2017, vivo began in-depth cooperation with Qualcomm to try in ultrasonic fingerprint identification scheme. However, at that time, it was still in the early stage of the development of screen fingerprint, the technology of ultrasonic fingerprint identification scheme was not mature, and the cost, practicability and other aspects were far from commercialization. Therefore, many peers looked down on the screen fingerprint technology at that time.

Although the ultrasonic fingerprint identification scheme can not be commercialized quickly, vivo still did not give up the screen fingerprint technology in a bad sound, but chose to cooperate deeply with synaptic. At CES 2018, vivo brought the first photoelectric screen fingerprint engineering machine, successfully solved the difficulties of cost and practicability, and has the ability of preliminary commercialization.

Vivo is at the top of the industry in the field of screen fingerprint touch technology

Just one month after the appearance of the engineering machine, vivo officially launched the world’s first screen fingerprint mass production machine – X20 plus UD. The identification principle is to identify the fingerprint through light, and finally refract the light back to the sensor. After matching correctly, the unlocking can be completed. As it is only the first generation of photoelectric screen fingerprint technology, although it has been commercialized, there is still a distance between the identification speed and accuracy and the physical fingerprint, but it is no longer a bad look at the screen fingerprint technology. At that time, many media and users speculated that the screen fingerprint technology will be the future development direction, and vivo has taken the lead.

Through painstaking optimization, shortly after the launch of X20 plus UD, vivo launched X21 screen fingerprint version equipped with second-generation screen fingerprint, which greatly improved the success rate of screen fingerprint identification. In the brand flagship vivo nex launched in the second half of the year, it not only has a “true” comprehensive screen scheme, but also carries the third generation of screen fingerprint technology, which has been highly practical, and the unlocking speed and accuracy can meet the normal use needs. It is precisely because of the success of nex that many manufacturers realize the importance of screen fingerprints. At this time, vivo is already in an absolute leading position in the industry.

Vivo continued to conduct in-depth research and development on screen fingerprints, and soon launched the x23 equipped with the fourth generation of screen fingerprints, which was double optimized at the software and hardware levels to make its unlocking speed reach 0.35s. At this stage, it has begun to gradually replace physical fingerprint identification. The nex dual screen version released at the end of the year is a new attempt of vivo to fully screen, and also integrates the fifth generation screen fingerprint technology, which once again improves the unlocking speed to 0.29s, and adds DSP acceleration technology to accurately unlock in the face of more complex use environment.

Among the various models launched in 2019, the flagship x27 Series in the first half of the year and the nex 3 5g recently released are equipped with the latest screen fingerprint technology. The unlocking experience in each scenario is not inferior to the entity fingerprint identification scheme, and even better in terms of convenience. It can be said that screen fingerprint technology will gradually become the standard configuration of smart phones, and vivo’s models can bring the best screen fingerprint unlocking experience.

In addition to the mass-produced screen fingerprint technology, vivo is also planning for the future. With the apex 2019 concept machine displayed earlier this year, vivo has realized full screen fingerprint recognition for the first time, that is, it can unlock any area of the screen, bringing a more arbitrary unlocking experience. Although today’s screen fingerprint technology is still developing, it can be expected to be higher.

From the development history of screen fingerprint, vivo does play an irreplaceable role. It not only took the lead in launching the first screen fingerprint mobile phone, but also continued to develop and optimize the screen fingerprint technology, so that users can finally obtain a more easy-to-use screen fingerprint mobile phone. In the face of the future development of mobile phones, vivo has also made preparations in advance. The apex 2019 concept machine has made many users see the infinite possibility of unlocking experience. I hope that subsequent vivo will show more eye-catching technologies.
