OPPO R9 is the first mobile phone of OPPO that uses a positive fingerprint identification module. In the previous evaluation, we found that OPPO R9's fingerprint identification speed is amazing, but we still dare not assert that its fingerprint identification speed can surpass all mobile phones on the market at present, but its fingerprint identification experience is at least the first echelon, Now let's take a closer look at the fingerprint identification module of OPPO R9.
According to the location of smart phone fingerprint recognition module, there are three different fingerprint recognition modules on the market, which are located on the Home key on the front of the phone, the back of the phone, and the middle frame on the side of the phone. Take the iPhone 5s as an example. The iPhone 5s is the first smartphone that uses the push home fingerprint unlocking mode. Since then, the industry has set off a wave of fingerprint identification, followed by Samsung and other manufacturers.
At that time, because the only company with a mature home key fingerprint unlocking solution, AuthenTec, was acquired by Apple, this technology could not be used on other mobile phones for a while. However, with the development of technology, many companies have mastered the mature Home Key front fingerprint identification scheme, including Huiding Technology and Swedish Fingerprint Cards.
This OPPO R9 adopts the FPC1140+FPC2050 solution of Swedish Fingerprint Cards. Among most mobile phones equipped with front fingerprint identification modules in China, most of them also choose the scheme of Swedish Fingerprint Cards. Compared with the back fingerprint identification, the front fingerprint identification will bring a better experience. For example, when the phone is placed on the table, the back fingerprint identification phone must be picked up before it can be unlocked. In daily use, pressing the Home key to unlock will be faster than the back fingerprint unlocking.
The advantage of back fingerprint identification is that it places the fingerprint identification module on the back of the mobile phone, so the contact surface of the module can be enlarged, thus improving the success rate and identification speed of fingerprint identification. This is why we think that the fingerprint identification speed of domestic back fingerprint identification mobile phones is faster than that of iPhone and other front fingerprint identification mobile phones. However, although OPPO R9 uses the front fingerprint identification module, it can do fingerprint identification faster than the back fingerprint identification, which is really amazing.
OPPO R9 uses the latest generation of fingerprint identification module, uses zirconium gem as the fingerprint key material, has 8.5 Mohs hardness, and has a dielectric constant higher than sapphire, which makes its fingerprint identification more sensitive. It only takes 0.2s to unlock the fingerprint in the black screen or the bright screen state - which is about equal to the blink speed of human beings, fast enough to not feel the process of fingerprint identification. R9 fingerprint recognition system is divided into three parts: self-learning function, automatic dynamic matching function and adaptive function.
First of all, the self-learning function automatically learns the user's fingerprint when the learning conditions are met. The system will automatically add the edge part of the fingerprint that has not been entered before to the fingerprint database, and its fingerprint will be more accurately recognized.
Secondly, the automatic dynamic matching function ensures that the sequence of template images in the database is always consistent with user habits. The self matching system will automatically remember the most commonly used fingerprint and pressing position of the user, and automatically match the fingerprint database images, and compare them in priority in advance to speed up the identification
The last is the adaptive function, which can automatically detect the scene, and can only adjust different electrical intensities. When the hand is wet and there is oil, the electrical intensity will be automatically increased, and the identification will be more sensitive.
The fingerprint lock of OPPO R9 can be applied to all the apps of the machine. You can set all the apps of OPPO R9 to the mode that fingerprint is required to unlock access. Fingerprint unlocking has a wide range of applications.
OPPO R9 fingerprint identification video demonstration:
In the actual test, OPPO R9's fingerprint recognition speed is very fast, and the recognition success rate is very high. Both the speed and the success rate are far better than iPhone 6s Galaxy S7 edge。 In several demonstrations, OPPO R9 was unlocked even after the iPhone 6s screen was lit. This is not a problem of transitional animation at all. Its fingerprint recognition speed is amazing.
summary
The fingerprint of OPPO R9 can not only be widely used for mobile phone encryption (full App encryption), but also far exceeds that of similar smart phone products in terms of speed and accuracy. The boom in smart phone fingerprint recognition originated from the iPhone 5s. As a pioneer of this technology, Apple failed to carry it forward and was gradually overtaken by some domestic mobile phone manufacturers, and OPPO was one of them.
