- Trinamix has unveiled a face unlock sensor that can hide under an OLED phone display.
- Your phone wonâ€™t need a notch for secure and effective sign-ins.
- The first devices using the technology should arrive in the first half of 2022.
You might not have to settle for a thick bezel or notch just to get secure face authentication. Trinamix has introduced a 3D face unlock sensor that can hide under an OLED phone display, making all-screen phones that much more practical without turning to fingerprint readers.
The company told Android Authority that its under-display face unlock system stands out through the use of data. In addition to capturing infrared light with a dot pattern, the technology uses â€œBeam Profile Analysisâ€� to gauge the distance and material. It offers the â€œsame levelâ€� of performance as conventional time-of-flight and structured light systems, according to Trinamix. The only major requirement is a display similar to those used for under-screen selfie cameras.
The technology will be secure enough for mobile payments, and will even offer skin detection to be sure thereâ€™s a real person unlocking the phone instead of a photo or head mockup.
Youâ€™ll have to wait a while to find face unlock under the display. Trinamix hasnâ€™t named customers, but phone makers are testing the system and could put it into shipping products by the first half of 2022. People attending Mobile World Congress Shanghai (yes, an in-person event) can see a live demo between February 23 and February 25.
As with under display selfie cams, thereâ€™s a real chance this face unlock method will involve some compromise, at least early on. It might also be a tougher sell if the pandemic still demands widespread mask use. Still, this hints at a future where you donâ€™t have to choose between an uncluttered screen and hands-off unlocks.
