Vivo before Apple puts a fingerprint sensor behind the screen
Rumors attributed to Apple’s attempts to place the fingerprint sensor behind the screen, but to the surprise of many the first this technology is demonstrated by another company.
Qualcomm has just introduced its new ultrasonic fingerprint sensors, which, in particular, can be placed behind the OLED screen with a thickness of 1.2 mm, as it turned out that the Vivo is ready a prototype of a smartphone with the new sensor.
The basis for the prototype model Xplay6. The sensor is placed behind the screen, according to a source familiar with his work, behaving as usual. However, the recognition rate is much lower. Perhaps this is due to the fact that the development is in the prototype stage. In addition, the sensor corresponds to only a small portion of the screen — it would be convenient to be able to unlock the smartphone by touching the right thumb anywhere on the screen. According to Vivo, this has increased the cost of the product, but it is possible that the sensor will still be much more common — the ability to recognize fingerprints will give the lower half of the screen.
In addition, it was shown the operation of the sensor under water.
When development will appear in the serial devices — while no accurate data. Assessment Qualcomm, the first serial device with sensors to scan fingerprints through the glass and metal will be released in the first half of 2018. A sensor for scanning across the display will be available to OEMs in the fourth quarter of 2017.
