So far the fingerprint sensor standard, located on the front under the screen and in the back. In both cases the sensor always remains in sight, but Qualcomm has introduced a new technology of fingerprint sensors that work under the screen or under the back .
This will allow the fingerprint sensor to be hidden and at the same time simplify the manufacture of submersible devices. This technology has been presented at the MWC of Shanghai and according to the company itself in 2018 it will be available for use.
The funny thing is that one of the best-known Chinese manufacturers, Vivo, has also launched a prototype that approaches the same technology presented by Qualcomm. This tells us that the starting signal has been given, now all the manufacturers will run to be able to develop this technology as soon as possible.
Qualcomm introduces a fingerprint sensor technology under the screen.
The main characteristic of these sensors is that they will remain hidden from the user, but the device needs to meet a series of requirements. When integrated into screens, it should be OLED-type , so it already points to high-end devices.
The sensor works by means of ultrasound , so it must be placed under a very thin material, such as glass or metal. In mid-range mobiles, which currently almost all equip a metal body, it would be easy to integrate these fingerprint sensors in the back.
In addition, these biometric sensors will have the added ability to measure heart rate and blood flow . Without a doubt, they are all very attractive additions for the end user and that we will surely start to see during the summer of 2018.
Nobody expected this news from Qualcomm, as it is a company better known for the advances of its processors, but it has definitely surprised us all.
