The technology was developed with the ability to scan through OLED displays stacks of up to 1.2mm thick, up to 0.8mm of cover glass, or up to 0.65mm of aluminum - but it can not work properly with an LCD screen. Specifically, they can scan through OLED display stacks up to 1200um, up to 800um of cover glass and up to 650um of aluminum. These new sensors are highly advanced and ambitious and they are certainly a major departure from the existing technology in use. Next, expect screens with fingerprint sensors included. Meanwhile, the Glass fingerprint sensor works through displays and/or glass surfaces up to 800μm thick.
These new fingerprint sensors have been designed for use with the Snapdragon platform, but there are stand-alone sensors that'll work in other situations too. Since the smartphone market is dominated by big screen devices, Vivo seems to be setting the bar higher by launching a phone that has a fingerprint sensor embedded under the display. The technology in the exhibition includes Vivo under display fingerprint scanning solution, Digital signal processing photography solution.
Other than recognizing the user's fingerprint, it is also created to detect heart beat and blood flow for improved mobile authentication experiences. Samsung was similarly rumored to do so for the upcoming Galaxy Note 8, but we have heard that the company is still trying to work out the kinks, so much so it looks like the competition has beaten both of them to the punch. The company has already announced the latest range of 400-series chipsets for mobile platforms that will be built on the 14nm technology. As demonstrated in a hands-on demo by Engadget, you simply press your thumb to the display and the device unlocks within a second or so of reading your fingerprint. The first Snapdragon chips that will take advantage of the new Fingerprint Sensors will be the Snapdragon 660 and 630, which were also recently announced by the company just last month.
