Fingerprint unlocking has now become one of the most commonly used ways for us to unlock mobile phones. It has experienced upgrades from sliding fingerprint recognition to press-type fingerprint recognition unlocking methods, from back fingerprints to front fingerprints and side fingerprints. Change of fingerprint unlocking position. With the advent of the full-screen era of smartphones, the screen-to-body ratio of mobile phones continues to increase, and the physical fingerprint recognition buttons on the front have also evolved into screen fingerprint recognition.
Compared with physical fingerprint recognition, screen fingerprints can maximize the screen-to-body ratio of mobile phones, but the recognition speed and accuracy are still slightly weaker than the already quite mature physical fingerprints. Recently, domestic mobile phone manufacturer OPPO has obtained the authorization of an ultrasonic fingerprint recognition patent, which can improve the accuracy of ultrasonic fingerprint recognition, allowing us to see new possibilities for under-screen fingerprint upgrades.
(Fingerprint Identification)
According to the Qichacha APP, OPPO’s patent authorization is called “Ultrasonic Fingerprint Identification Method, Device, Electronic Equipment and Storage Media”, and the public number is CN110298313B. According to the patent abstract, this patent divides the touch display screen corresponding to the fingerprint press operation into a first area and a second area, and the first area corresponds to M ultrasonic fingerprint recognition modules, and the second area corresponds to N ultrasonic fingerprints. For the identification module, M and N are both positive integers, which means that there can be more than one fingerprint identification module in these two identification areas. When a fingerprint pressing operation is detected, the ultrasonic fingerprint recognition modules corresponding to the first and second areas will be awakened to perform ultrasonic fingerprint recognition, thereby improving the accuracy of fingerprint recognition.

The current common screen fingerprint recognition is optical under-screen fingerprints. In comparison, the ultrasonic under-screen fingerprint solution is more penetrating. It has strong anti-fouling ability, can be unlocked even with wet hands, and has a high recognition rate and fast recognition speed. This newly authorized patent from OPPO uses ultrasonic fingerprint recognition modules in two display areas to perform fingerprint recognition, further improving the accuracy of recognition. If this patented technology can be implemented, it will undoubtedly increase the speed of screen fingerprint recognition. and accuracy.

In addition to the ultrasonic fingerprint recognition patent authorized this time, OPPO has always made achievements in the field of fingerprint unlocking. A while ago, OPPO obtained a patent for full-screen fingerprint recognition, which can provide a structure to set the fingerprint recognition function on the display screen to achieve full-screen fingerprint recognition. With this technology, users do not need to align a single fingerprint position when unlocking. They can unlock the fingerprint by pressing anywhere on the screen. Compared with the current single-area fingerprint recognition, the unlocking experience will be greatly improved.

In general, OPPO has been studying fingerprint recognition technology and constantly exploring front-end technology. There are full-screen fingerprint scanners in the past. With recognition patent authorization, perhaps the entire screen can support recognition and unlocking in the future; now there is an ultrasonic fingerprint recognition patent to further improve the accuracy of fingerprint recognition. As OPPO obtains these patent authorizations, perhaps in the near future, we can see OPPO actually implementing these technologies into mobile phone products. By then, I believe it will greatly improve the experience of using under-screen fingerprint recognition and bring about a better screen fingerprint unlocking experience. Innovation and upgrade.
