Ming-Chi Kuo: Qualcomm's under-screen fingerprint scanner has speed and accuracy problems

Ming-Chi Kuo: Qualcomm's under-screen fingerprint scanner has speed and accuracy problems
Qualcomm isn't going to like what analyst Ming-Chi Kuo has to say about its in-screen ultrasonic fingerprint scanner technology. But knowing his famously accurate predictions, based on tight supply chain contacts, it's most probably true.

The in-screen fingerprint scanning technology, recently showcased in a prototype smartphone by Chinese manufacturer Vivo, suffers from various drawbacks that prevent manufacturers from implementing it in their handsets.

Notably, key speed and accuracy issues must be resolved before the system is ready for prime time. The latest version, demonstrated on the Vivo phone, has improved scan-through rate and is able to discern real and artificial fingers. But the scanner still isn't quick and accurate enough to facilitate an adequate user experience.

Moreover, the technology requires special adjustments to work. It needs both a thinner cover glass and a flexible OLED panel to work. Currently, the latter technology is out of reach for many manufacturers, though this is going to change as production becomes more affordable and abundant.

Although Qualcomm believes that the fingerprint scanner will be ready to appear in smartphones next summer, Ming-Chi Kuo thinks it will take longer for this to happen. In the meantime, Samsung is working on its own under-glass fingerprint scanner. But it's said to be struggling with an issue that involves an unnaturally bright spot where the scanner is positioned. You can read more about that here.

Unfortunate. Will be a nifty feature when properly executed.

*Oops* who will rescue samsung now? Or will they go with their unreliable iris scanner or their lol worthy facial recognition app?

vivo demoed this tech last week, and somehow PA skip that news.. it's slow and not always work (kinda like 1st gen touchID)

1st generation touch ID has been a good implementation: it is slow(er) than the second (it isn't slow at all) and it is pretty much just as accurate as the 2nd.

And if it doesn't work, you know Apple won't "wreck the stylish" iPhone by placing a sensor on the back, which means the next gen iphone won't have touch ID.

There is no way Apple would release the tenth anniversary iPhone without a fingerprint reader. If the under-display fingerprint tech isn't ready for the iPhone 8, Apple would have no choice than to place it at the back of the iPhone 8, assuming the iPhone 8 will be bezel-less as the rumours have suggested. Otherwise, Touch ID will be embedded in the home button placed at this centre of the bottom bezel of the iPhone 8, which means big bezels à la iPhone 7 Plus.

Mass production of the new iPhone will start soon or has already started. Thus the very reliable leaks will start soon.

Apple has its own in house team working on this playa. It has nothing to do with Qualcomm. What's going to e funny is how good Apple will be looking when they release the ip8 with it after all the struggles from these other manufacturers. They will have to show them how to do it like always. Think Touch ID vs the Atrix crap.

Playa, AuthenTec built the finger print scanner for the Atrix and the iPhone (not in-house). The only thing Apple has ever shown anyone is how to get in line for stuff other people make. Think Touch ID and Atrix crap, then think AuthenTec , the company that made both.

you can keep dreaming. apple hasn't been making new tech for a very long time. they wait until others make it work and tend to make it better.

Funny, that is exactly what another dude said on another topic about Samsung tech and the reply was that, if it works on tech that hasn't been good or used in mobile, than that's a new tech. Kind of like Apple, don't you think?

Embed the Scanner in the backside Apple Logo. Done.

Or better still, in the power button. The best of both worlds. Anything but the horrible back placement tbh.

Weren't you, for the past few months, acting like you had insider info and were 100% sure Apple was putting the FPS under the display?

Yeah Bankz was apparently he has insider info and apple were the 1st to included a FPS under the dislpay but the news article today shows how wrong he was. There's alot of rumours of what the Iphone 8 will have but thats what they are rumours. Apple tend to bring out 1 or 2 big features each year. Bankz for some reason thinks this year they bringing out FPS under display, 3d face recognition, AR features. I think he just gets very excited reading Apple leaks.

I can 90% assure u they will embbed the fps under the display. Though plans could change but its highly unlikely, except some dramatic happens, which as at april was very well on course.

Bankz...90% certainty doesn't cut it, dude. You've been bragging left and right about how they were gonna have a perfectly functioning embedded under glass FPS. We've seen the same comment from you, several times a day, for the past few months where you flaunt iPhone 8 features, with screen embedded FPS being one of them. Don't try and get out of this now because of this article lmao! You're just afraid of being wrong and having everyone mocking you. So suddenly....you're 90% sure instead of 100% sure. Okay then.

"Locked" to "90%" Your goal posts have wheels.

Even the world master AMOLED display which can make bendable, Stretchable, transparent rollable...etc.. it struggling to put fps under it's highly advanced display. Then How can you even think .... that a rotten fruit seller can put a fps under outdated 3 year old AMOLED....

This hypocrite started throwing insults at me when I challenged him that from the leaks, it looks like Apple will pull a Sony and place the fingerprint scanner underneath that long power button it was constantly being shown in the leaks. He was mad I dared and challenged his rumors that it was a lock in that Apple will be placing the fps underneath the screen. Few weeks later, here he is, acting like he is Mr. Knows Everything, and how is that some sort of genius who figured that Apple didn't increase the size of the power button for nothing.

Btw, who this ming chi quo guy anyway? Always pessimistic about everything. How the hell does he know for certain that they'll be slow when they havent been mass produced? Talk bout a spoil spot.

He's the guy who predicts things without constantly back-tracking like someone on this site. http://www.phonearena.com/news/Ming-Chi-Kuo-iPhone-7-Plus-may-have-a-dual-camera-version-with-optical-zoom_id77755

Hmmmm? Not ready for prime time. iPhone 8 may not have this under the screen. I'm cool with the power button. Rather not see a half baked piece of tech. But I might just go 3 years on current device.
