This weekend, I came across Samsung Display’s keynote speech at this year’s International Information Display Meeting (IMID) 2022. For those who follow industry trends, Samsung Display’s keynote opened your eyes to what’s in store for mobile, foldable, slider, gaming and automotive. attach. Below is a YouTube video of the keynote, and if you’re like me, you’ll need to turn on closed captions (CC) in order to follow along.
One of the technologies Samsung Display CEO Dr. JS Choi talked about was next-gen all-screen fingerprint-enabled displays. Samsung has developed a very powerful organic photodiode which will soon market a fingerprint sensor available on the whole screen. Instead of having a fingerprint sensor found on a single area of a smartphone like today, future smartphones will be able to have full-screen fingerprint displays that could capture multiple fingerprint scans, like shown in the Samsung Display slide below.

According to Dr. Choi, this means that the level of security will increase significantly and lead to the development of various applications. Moreover, the all-in-one sensor will integrate a 5G antenna, biosensors and many more.
Specifically, while Dr. Choi was talking about biosensors, the slide referred to specifically identified sensors related to “blood pressure and blood sugar,” two areas of health that Apple has been working on for a while now for Apple Watch. The biosensors built into Samsung’s next-generation OLED displays will be revolutionary.

Before offering a full-screen fingerprint display, Samsung filed a patent application for a dual fingerprint display for foldable devices. It was made public on November 24, 2022.
According to the patent, the fingerprint module will also include additional sensors such as an iris sensor, pressure sensor, and illuminance sensor. Samsung figure. 7 below is a diagram illustrating an arrangement of a first fingerprint sensor and a second fingerprint sensor on a foldable electronic device.
Unfortunately, some Samsung patents simply focus on the mechanics/engineering of a technology and do not provide readers of the patent with an explanation of how that feature will be used. Although common sense suggests that to open the user’s home screen, the user will need to use two fingers or two thumbs to open it, which doubles the security.
Samsung’s Korean patent filing can be viewed on the WIPO IP portal under number WO2022244975 entitled “Foldable electronic device comprising a plurality of fingerprint sensors”.
