Electronic enthusiasts eight o'clock in the morning: In 2017, there has been a small change in smartphone design, including the use of a 2:1 slim screen, canceling physical buttons, and increasing screen share. One of the premise of this change is the elimination of fingerprint recognition based on physical keys. According to the latest news from foreign media, Qualcomm has launched an off-screen fingerprint recognition solution, and next year's smartphones are expected to popularize this technology.
According to the US technology news website AppleInsider, Qualcomm and Chinese mobile phone manufacturer Oppo jointly demonstrated the technology and prototype design. It is reported that the fingerprint identification module will be placed under the mobile phone display.
It is reported that the screen recognition solution developed by Qualcomm uses ultrasonic technology, which is already the second generation technology. Qualcomm said that the new fingerprint recognition technology can penetrate 650 micron aluminum material, 800 micron glass, and 1200 micron OLED display glass substrate, but the sensor used for fingerprint recognition is slightly different for different isolation materials. .
According to Qualcomm, this ultrasonic sensor technology can be used not only to identify fingerprints, but also to measure heart rate, blood flow and other information. In other words, this technique can identify whether the "finger" it sees is a real human finger, not other counterfeit materials.
Qualcomm's application processor will also gradually support this fingerprint recognition technology, and the newly released Snapdragon 630 and 660 chips are already supported. In addition, Qualcomm also said that the identification technology can support other application processors other than Qualcomm.
In July this year, Qualcomm will provide mobile phone manufacturers with sample parts for the screen fingerprinting solution, which can penetrate glass and metal. Engineering samples of related sensors will be available to manufacturers in October.
Smartphones or mobile devices using this technology are expected to be available in 2018.
Screen fingerprinting has become a hot technology. In the Apple 10-year mobile phone released this fall, Apple will also adopt this technology, thus eliminating the old physical buttons. It is reported that Apple's plan has encountered some technical challenges. Previously, the fingerprint module was not mature. Apple once planned to cancel the fingerprint on the screen and transfer the fingerprint recognition module to the back of the mobile phone. However, the latest news said that the screen fingerprint technology has been "fixed", and Apple will successfully cancel the physical button.
Samsung Electronics Galaxy S8 mobile phone, Samsung originally planned to implant fingerprint recognition on the lower side of the screen, but the technology is not enough, but the identification module can only be placed on the back of the mobile phone. The mobile phone canceled the physical button, and the screen ratio increased greatly, which was highly praised by the industry.
In October last year, Apple also applied for a patent for a screen-printing technology, which is said to be very similar to the Qualcomm program.
In the ten-year version of the mobile phone, Apple used what kind of screen fingerprint recognition technology, which is still unknown. However, it is certain that if the fingerprint of the mobile phone screen is smooth and reliable, the fingerprint under the screen will become a popular technology for smartphones next year.
Under the demonstration effect of Apple and the Qualcomm technology solution, next year's smartphones are expected to cancel physical buttons, significantly reduce the area of ​​the upper and lower borders, and the relatively low-profile "ugly" mobile phones will be difficult to stand on the market.
