vivo screen fingerprinting | you certainly have special care

In the era of full-screen smartphones, not only the proportion of screens has changed, but the historical significance of its existence is to promote technological change, and finally we have the fingerprinting of the screen under the display area. On January 24, 2018, Vivo released vivo X20Plus screen fingerprint version in Beijing, cancel the back fingerprint instead of the screen fingerprint recognition, the other configuration changes little, 4GB RAM +128 GB ROM, color black gold, priced at 3598 yuan.

We got the machine the first time, I believe we already have long-term fingerprinting under the screen long-awaited. Nonsense to say, so that the test is not so good to know, let us tell you what you want to know about the vivo screen All the fingerprints

The most intuitive advantage of the fingerprint form on the screen is to enhance the sense of unity

Compared to ordinary fingerprint recognition, the screen can give us what the fingerprint? Else not to say, the most intuitive feeling is the integration of the appearance of the phone to strengthen the vivo X20Plus screen fingerprint version to remove the back of the fingerprint hole, the back of the machine Body clean and simple look.At the same time do not need to open the front panel, to a certain extent, to ensure that the front panel screen aesthetics.

Except for the back fingerprinting, the screen fingerprints did not change the appearance significantly

From the appearance point of view, in addition to color, the two phones really not much changed.Importantly, due to the cancellation of the back of the fingerprint recognition module, the overall thickness of the fuselage but reduced by 0.1mm (X20Plus screen fingerprint version of the body size 165.2mm × 80.02 mm × 7.35 mm, regular version 165.32 mm * 80.09 mm * 7.45 mm).

In fact, the screen version of the screen fingerprint is not completely different appearance. Interesting screen state, a certain angle Strong light exposure , We can see a sensor that is used for fingerprinting and tilting, and the light is generally not found.

The trigger mechanism for fingerprinting needs to be lit up first

And the first generation of fingerprints and facial recognition trigger mechanism is similar to the recognition module is not always in the power state, you need to trigger. Vivo screen fingerprinting is based on photoelectric reflection technology, some say optical fingerprint identification method, so the need for fingerprinting At the first light to trigger recognition.

Vivo optical fingerprint trigger provides two ways: First, shaking light identification mark, press the sign to identify the equivalent of facial recognition lift wrist bright screen, but the vivo fingerprint trigger more sensitive; Second, double-click the bright screen , Then fingerprint recognition.

Recognition rate recognition speed is slightly slower than the traditional capacitive fingerprint

From our testing, the recognition rate of the screen fingerprint is still quite good, even if you hold down more than half can unlock, as long as do not deviate from the recognition position, fingers do not move too fast, unlock success rate will be high.

Judging from the speed of recognition, the screen fingerprint is still slightly inferior to the mature capacitive fingerprint recognition. In the state of the screen, press and hold the fingerprint recognition logo, press and hold the location will appear highlighted, and then there will be a circuit to walk Transition animation, the animation can be completed after the unlock.

In actual use, we compare the speed of the vivo screen fingerprint with that of the iPhone X. As the iPhone X lift the wristwatch to unlock, you also need to manually slide, in contrast, the vivo screen fingerprint pick up the phone can be unlocked The efficiency is higher.

There are some restrictions on fingerprints on wet hands and film screens

Mature capacitive fingerprinting flaw lies in the wet hand can not be identified, sweat for the hands of users, the basic function of summer fingerprint recognition is paralyzed. So vivo screen fingerprints can be wet hand to unlock it? The test found that, Dipped too much water on your finger can not be unlocked, but the simulation of natural sweat wet hand state, there is no problem with the fingerprint unlock.

So the film on the screen fingerprint affect it? We find an ordinary plastic film to test and found that although the foil can be unlocked, but the recognition rate has declined.So you want to foil users, can only wait vivo screen fingerprints Official custom film.

There is no difference between screen recognition and normal fingerprint recognition

Screen fingerprinting functionality, support for WeChat, Alipay payment, support for handheld bank fingerprint verification, support for application lock decryption, etc., and there is no difference with the conventional fingerprint recognition.When fingerprint recognition is needed, the fingerprint identification will automatically light up.

The above is about vivoX20Plus screen fingerprint version of the product evaluation reports, vivoX20Plus screen fingerprint version of the appearance, screen, camera, battery life, performance and other follow-up content, please continue to focus on the report on vivoX20Plus screen fingerprint version of the report.

How to recognize the principle of vivo screen fingerprint is how to achieve

Vivo screen fingerprinting is a photoelectric reflection technology supported by Synaptics, a technology that uses a combination of capacitive and ultrasonic solutions previously used in cell phones to capture fingerprint images by light reflections, specifically - 'specifically adapted The RGB Pixel of the OLED screen emits light, penetrates the 0.68-mm-thick glass cover and reaches the finger. The reflected light is different due to the different lines of the finger, which then penetrate the screen and reach the fingerprint sensor for fingerprint identification. Since the body micro-official)

During recognition, a certain intensity of light is required for recognition, so when the recognition mark is pressed, a partial highlight is provided to provide sufficient reflected light.

In addition, the fingerprint input, the system will remind a little hard to press the recognition effect is better.The reason is not because the screen integrated pressure sensor, but when pressed hard fingerprint on the screen, fingerprint recognition sensor can get more Clear fingerprint reflection image.

We also mentioned earlier that the sensor placed obliquely under the screen, which is because when the sensor is placed horizontally, the pixel arrangement of the OLED screen covers the light of a part of the sensor and can be exposed more and easily after being rotated by 45 degrees.

Prior to the famous 'Apple analyst' Guo Mingchi has said that optical fingerprint technology is poor penetration, it is easy to be affected by the light source and the screen color, there is the problem of recognition error. And vivo precisely with high-quality light-emitting materials and excellent fit Technology solves these problems.

Why custom membrane on the film vivo will not affect the recognition rate

We have just tested, although ordinary plastic film can achieve fingerprint recognition, but the recognition rate will decline.So vivo custom film is how to ensure the recognition rate of the screen fingerprint?

It is reported that the quality of the film need to be stretched, but in the process of stretching will produce streaks, these streaks will make the light changes, seriously affecting the optical fingerprint recognition. And our experimental common plastic film, should not be stretched Of the film, to achieve recognition, but due to the bubble and other factors led to recognition rate is not high, of course, the film too thick will have an impact on the identification.

The customized film, there is no directional stripes, moderate thickness and excellent protection of the film, so in theory, vivo custom film costs will be higher.

See here I believe we have on vivo screen fingerprint has a more comprehensive understanding of how, vivo X20Plus screen fingerprint version Is your dish?
