The ZTE Axon 20 5G became the first phone with an under-screen camera to go on sale.
For some time now, several manufacturers have been working on placing the front camera of their phones under the screen. Soon it will not only be possible to place the front camera under the screen, as it will also be possible to place the facial unlocking sensor under the panel, as Trinamix has made official.
Trinamix has unveiled a 3D face unlock sensor that can be placed under an OLED panel. This sensor would allow to make an all-screen phone much more comfortable and that in the near future we could already see in some Android phones.
This Trinamix under-screen facial unlocking system stands out for its use of data. In addition to capturing infrared light with a pattern of dots, the technology uses a function called Beam Profile Analysis to measure distance and material. According to the company, it offers the same level of performance as systems such as ToF. In this case, the only important requirement is the use of a screen similar to the one ZTE has used in its cell phone.
This technology can be used in many cases, such as mobile payments, where it will be sufficiently secure. In addition, it will even have skin detection to ensure that it is a real person trying to unlock the phone and not a photo or some kind of cardboard.
This technology from Trinamix will hit the market in the near future, the brand has said to be working with some phone manufacturers, but they have not given names at the moment. The manufacturers are currently testing this new system, so it doesn’t look like it will be on the market this year. It is estimated that the first shipments could start in the first months of 2022. In addition, the firm will show it live at an event in Shanghai at the end of February.
As with an under-screen camera, it is possible that this under-screen facial unlocking system is going to be a compromise. The quality could be worse or it would take longer to recognize the face than a normal sensor, but it opens the way for more general use in the future.
