[Forbes] Why Mobile Could Be The Primary Driver of 4K Experiences

Why 4K-Derived PPI matters

My first reaction when I heard of 4K displays on phones and tablets was skepticism, until I started researched the topic. First of all, many in the industry generally agree that humans can perceive differences in max PPI ranging roughly from 350 to 575 PPI at a ten inch distance. The better the vision, the higher the visual acuity, and my Note 3, at nearly half the maximum, has a ways to go. Personally, I am painfully near-sighted and I can see pixels on a phone or tablet where others cannot. Others in the industry (Sharp and Qualcomm) and some researchers are talking about vernier acuity, or the ability to see the differences among two line segments. This suggests that human’s visual system is much more complex, indicating that humans can assess differences 5-10X the detail of visual acuity.


Of course, my quote of choice has less to do with mobile and more to do with the screen.

Finally we have an article with more than the usual "lines blur together at such and such a distance, therefore 4K is useless" drivel.

Vernier acuity = sensitivity to jaggies. 5-10x sensitivity compared to normal visual acuity. That's what I'm talking about.

Good. I have pretty good eyesight and I can still see pixels on high resolution phones. I really want 4k to become mainstream.

Yep. That's the real metric to use, and for some reason we humans are very, very good at seeing differences between two lines. Getting rid of jaggies is pretty much the hardest task as far as how displays interact with our visual system. Nice to see someone paying attention to it with more scientific rigor.

I will point out though that 4k *is* useless for TVs. They are, actually, far enough away so that you won't be able to see the difference.

Naaah. You just sit at 1 meter from a 32'' one and 4K makes perfect sense smile.gif

I always maintained that even if ppi is past the point where we can distinguish individual pixels, at the very least it will still add natural anti-aliasing. Somewhat gratifying to see the same result from research.

You need to make use of that kind of eyesight in a high paying job, cause DAYUM. I can't see pixels unless i looked really hard on my note 2 1080p screen. 4K on mobile (unless it's tablets) is a waste

But I do want that 4K 27" screen

The Note II utilizes a 720p screen resolution. Not 1080p. What you should be interested in is the pixel density.. and that's that PPI number. I have them both highlighted.

The higher the pixel density (PPI) is, the harder it gets to spot those pesky pixels thumb.gif

PPI is useful, but halfway there. What really matters is pixel per degree, which takes into consideration viewing distance.
post #9 of 39
are smartphone manufacturers going to keep pushing (mostly) pointless ppi upgrades as a way of promoting phones? probably yes. is a 500ppi 5" device going to be equivalent to the experience you get on a true 4k 27-30" display? no, just no
post #10 of 39
strong username to post content smile.gif

I've been waiting for an Android 8" tablet to ship with a 64-bit processor and 1600p for $300
may be I can hold out another year and perhaps they'll release 4K mobile devices then. rolleyes.gif
I don't care how crappy Android games are...being able to run 4K content natively is a major selling point to me esp if I wont upgrade my TV/monitors for a very long time
