Just days after Synaptics announced that it had started mass production of its first optical In-Display Fingerprint Sensor, it has now been revealed China's Vivo will bring the first device with the integrated sensor. The phone will come from Vivo who, while isn't entirely popular in the United States, will likely make its name known across the industry as the first to embed a fingerprint reader in a display. In addition he says that the CMOS image sensor is.7mm thick and reads the fingerprint through an OLED screen. However, it may soon become possible to get a front fingerprint sensor on a full-screen smartphone.
The technology, named Clear ID works like this: There will be an illuminated fingerprint image below the display on the screen and by touching this, the phone can be unlocked. The in-display sensors work with wet, dry, and cold fingers, and can unlock devices including while it's sitting on the table, at any angle, or while in a auto mount. Synaptics, in fact, claims its Clear ID is twice as fast as Apple's Face ID. It's also around three times less expensive than Face ID, so the overall cost of the phone won't be inflated. SentryPoint technology will be part of the system, providing companies with a wide variety of highly secure authentication features. To put all of this in layman's terms, good luck trying to fool this sensor.
While Vivo might not be the first name people think of when it comes to top 5 phone manufacturers, IDC reports that it was behind only Samsung, Apple, Huawei, and OPPO in Q1 2017. Pre-production units are already available for testing and they're living up to the hype. Apparently, the display has to be woken from the power button, then the finger goes on the display to be unlocked.
As noted in the original article, recent leaks showing the fingerprint sensor on the rear of the handset suggested Synaptics' tech wouldn't debut in the Galaxy S9. This will help with processing for rounded corners and notches, smooth auto-dimming and support for extra long displays.
Named "Clear ID", these are expected to work exactly like the home button fingerprint sensors.
This is a critical detail, as companies such as OnePlus that have tried to emulate Apple's facial recognition tech without advanced depth-sensing cameras have had to compromise security in favor of convenience.
