Qualcomm fingerprint reader
Fingerprint readers hidden on the screen of smartphones are finally coming: Qualcomm has demonstrated a technology that allows the installation of biometric ultrasonic sensors under metal, glass or even OLED panels. And they can read your finger even if the device is submerged in water.
The demonstration was done on a modified Vivo Xplay 6 smartphone to house the Qualcomm sensor. Here’s a video explaining how technology works:
Qualcomm says its new biometric reader is the first commercially available scanner that can be installed under 1,200 micrometers (1.2 mm) OLED screen, 800 μm glass or 650 μm aluminum. To increase safety, the technology is able to identify heartbeats and blood flow in the finger.
But the sensor is still not perfect. The Engadget , which move in the prototype at an event in Shanghai, said: “Although the solution work as advertised, I thought the fingerprint recognition speed was noticeably slower – about a second between the first touch and the entry screen Initial “. This may explain why the Galaxy S8 did not come with the sensor on the screen .
In addition, the sensor recognition area is small: “In theory, the same detection technology could be applied across the screen, but this would significantly increase the cost of production.” There is a possibility that in the future, Vivo will place the sensor across the bottom half of the screen, which would already improve the experience.
Although the technology has been demonstrated by Qualcomm, the biometric sensors will be available even for devices without Snapdragon chips. There will be two versions: one for glass and metal, which will be released to trading partners later this month; And another for screens, which will reach the hands of smartphone manufacturers in the last quarter of 2017.
