Here at CES 2018, I had a chance to look at what some of us probably considered mere fantasy a few short years ago: a fingerprint scanner that can see through a smartphone display. It sounds like something that must be so complex it would be beyond explanation, but really, the basic principles aren't terribly difficult to grasp.
The short of it is this: smartphone screens are light-permeable, because they are porous. The thinner the display, the more light-permeable it probably is, and OLED screens are the thinnest currently being manufactured. By shining a bright enough light through the porous display, a sensor can observe the reflection of your fingerprint against the display components and use that to create a computer-readable image.

Getting the fingerprint sensor inside a display has been the next logical step for years (unless you're Apple). It has proven hard to crack the code on that, though. As displays keep getting bigger, it's time for someone to take the plunge, and Synaptics says it has the technology to make it happen. Its new Clear ID in-display fingerprint sensors are coming soon in partnership with a "top 5" smartphone OEM. That's a bit cryptic. Read More
We've reached a point in the smartphone world where most devices have fingerprint sensors. Some are faster and more accurate than others, but I think that most of us can agree that they're pretty awesome to have. Synaptics is a large player in the industry, although some may recognize the name from the touchpads on their laptops. The biometrics company announced yesterday that it's working on a new fingerprint sensor for security, convenience, and versatility. Read More
