Vivo smartphones will be first to feature in-display fingerprint sensor

A few months ago, China's smartphone maker Vivo has announced that it is developing an in-display fingerprint technology that will soon be presented on the next smartphone. Now the company has posted a new image teaser that reveals that the smartphone that will carry the technology soon launched.

According to Gizchina's report, Vivo has announced that it has collaborated with Synaptics, who is a pioneer in this field. With the cooperation of both companies will produce smartphones that have chip Clear ID FS9500. The chip is the hardware that will handle all the procedures related to the fingerprint.
The new chip will be announced by Synaptics in the coming weeks and this chip will support smartphones that have 18: 9 screen aspect ratio and 20: 9. This new chipset consists of a small CMOS sensor placed just below the AMOLED screen, and is ready to scan fingerprints when illuminated, with a "read" reflection of each finger scan. To make this reflection, part of the screen must be lit, and then the sensor will capture the shadow between AMOLED pixels.

Synaptics discloses if the whole process requires very little power, ie no more than 80mA. In addition, this process will also work in conjunction with all the relevant sensors from each smartphone, to know when to activate the fingerprint and turn on the appropriate portion of the screen.
Some companies claim the speed of their fingerprint scanning process can take place in just 0.2 seconds, and Synaptics also does not forget to boast a fingerprint scan speed of just 0.7 seconds. Although the numbers are still less quickly, but it will not be so felt because all the process is less than a second.
