 The next trend for smartphones is user interactions and unspecified, like vital monitoring, guest tracking or secure face authentication. This means adding a specialized camera on the front of the mobile, but who also wants phones with large displays and with no holes to enjoy a truly full screen. That's why a behind-all-edged camera is the best solution. Qualities of displays are improving, thanks to higher pixel density. Consequently, with lower transparency, camera sensing behind-all-edged is more difficult. To offer a turnkey solution, VisionX, Trinamix and ST-Microelectronics work together for cost-efficient and a fully secure behind-all-edged face authentication system. At MWC last year, we show our commitment to under-all-edged solutions, with Trinamix face authentication. This year, we complete the solution with innovative OLED display from VisionX, which is located here under the screen and does not need a hole. ST cameras are specifically tuned for this use case. Trinamix algorithm and module with highly secure and certified light-light data. VisionX display is customized with a small region where the OLED transparency is improved. They tune their technology to optimize both the performance and the manufacturability. Trinamix approach is natively compatible with the illumination pattern and they are quite immune to OLED artifacts. Robust, even when trying to hack the authentication with an expensive and very high resolution mask. ST global shutter camera embeds a pixel especially enhanced for the best near-earth sensing under all display. With recent breakthroughs, ST demonstrated highly improved image quality for 940 nanometer illumination. Mandatory for use under OLED sensing. This innovation was only possible thanks to our integrity in manufacturing, where low-level silicon bricks are developed congenitally with a full system. Thanks to the three-party cooperation, ST, Trinamix and VisionX, it's a unique and full-time key solution for under OLED face authentication. It's also a great opportunity for new user-centric features on mobile phones like guest tracking, virtual sim monitoring and many more. For more info, check out ST.com.
