Samsung Unveils World's First OLED Display With Built-In Fingerprint and Blood Pressure Sensing

Is it just me or does that not make sense? How can the reflected blood show the pressure? It would show a pulse rate yes. But how is the reflected light showing the pressure of the blood, if that’s the case any Apple Watch could do the same thing, and it can’t.

Curious about this also. All gold standard pressure measurements require pressure to stop flow in a major vessel than measure flow as it resumes. Finger is almost all capillaries and you cannot measure what we call blood pressure in capillaries.

Amazing that this kind of technology is being developed, but it's Samsung so I'm highly skeptical it will actually work well. Even if the hardware is spot-on, they will find a way to bungle the software. I'm saying this as a user of a Samsung phone and watch.

The good news for iOS fans is if the hardware is reliable, Apple might be able to make the software work (although Apple's track record with bugs hasn't been that great the last few years either). Or Apple will omit some useful functionality that all the Android devices end up having.

This sort of capability becoming a step closer to reality is the most exciting piece of tech update I have seen in a while.

"To accurately measure a person's blood pressure, it is necessary to measure the blood pressure of both arms," notes Samsung Display's press release. "The Sensor OLED display can simultaneously sense the fingers of both hands, providing more accurate health information than existing wearable devices."

Da-yum, y'all. The doctor's office has been taking inaccurate BP reading on me for years.😏 They only cuff one arm when measuring my BP.
MacRumors said:
Samsung says the system works because OLED light is reflected differently depending on the contraction and relaxation of the blood vessels inside the finger, and when it returns to the panel, the OPD is able to recognize it and converts it into a blood pressure reading.

Measuring BP via lightwaves. That's some Star Trek technology there. I'll stick with devices that actually measures pressure for now. I'm old fashion.

Fingerprinter reader on the OLED. Yeah, I can believe that. Accurate BP measuring via OLED? Call me Thomas, Doubting Thomas.😐

Lots of people on here will probably jump in and rubbish this. I think it's great! Even if it's not perfect yet, this sort of development stops Apple from getting complacent. Competition is good.

Apple is complacent? Have you heard of Apple Silicon? Their A and M series of chips have put the rest of the microprocessor firms on notice and are far ahead.
Just because a company doesn't work on things you want them to, doesn't make them complacent. They don't care about fingerprint scanning in the screen, when the FaceId system is superior anyway. I don't get how anyone prefers fingerprint to FaceId unless they are a spy that changes faces every day lol

I wish Samsung offered some alternative to Android. I’m sure it would be insanity now, especially if Android and iOS are forced to allow third party stores. Still, Samsung is impressive. Sad that they stopped making cameras as well.

In the future, I will lose all my 5 fingers for someone to break into my phone :)
 
Hmm considering how Samsung named their QLED TVs...

Is this "Sensor OLED" a new Samsung invention that has nothing to do with OLED either?
 
Apple has been waiting for this for a long time. Once this tech matures it will adopt it ..., maybe Fusion Display or something and put it on Ultras first and ... you know the drill.

But, hey ... if it works well. We know Samsung advertisement machine very well as much as we know Apple.
 
I’m holding out until the screen can detect my alcohol levels and not unlock my phone. That way I don’t drunk text my ex’s. Maybe next year Samsung.

What competition?
They'd just be buying these from samsung for their iphone 18/19/etc the same way they already buy screens from samsung for their iphone 14 today.

Apple competes with samsung for a lot of things, but they're in kahoots with a lot of things too.

Presuming Apple is still using Samsung AMOLED screens in iPhones by that time. They may be in the process of transitioning to their own MicroLED displays.

MicroLED is still a long long way from being economical to manufacture; plus their main advantages are brightness and lifespan; brightness is good but lifespan isn't that important to a phone that gets turfed after 3-5 years; vs say a tv that ideally lasts at least a decade.

The screen is already one of the most expensive items in an iphone BOM, quadroupling it for a benefit to brightness (and longevity) won't make much sense; not until they refine the process enought o make it as cheap or cheaper than amoled is today.

They did - it was calles Tizen OS. But the biggest challenge was making developers to adopt Samsung's operating system. Let alone building a stable OS.

In fact, their watch used to run on Tizen until the last gen.
