Sharp has announced its intention to manufacture the world's sharpest display, a 5.5" IGZO screen with a 4K/UHD 3840x2160 resolution (806 pixels per inch), for some 2016 smartphones. Is 806 PPI too much? Tom's Hardware notes the drawbacks while celebrating the new milestone:
Although devices that are 1440p or even 4K will look even more stunning, there are indeed diminishing returns benefits-wise as the cost, the power consumption, or the GPU resources required to handle such high resolutions are significantly higher than the previous generations.
That's not to say that a 4K display today will necessarily cost more than a 1440p display did last year, but it does cost significantly more than a 1440p display being sold this year. Although the price ratios for components may remain relatively the same for the new technologies inside a new smartphone, if the benefits are increasingly smaller, then there's an opportunity cost, as well.
For instance, the extra cost to get a 4K display over a 1440p display this year could be used instead towards improving the device's camera. (OEMs could use a sharper lens, a larger sensor, improved OIS, and so on.) This sort of balance should always be taken into consideration.
[...] That doesn't mean higher resolution displays in smartphones are not useful. However, they could be even more useful for other applications; for example, 4K displays are ideal for VR. In order to have a VR experience that makes you completely forget you have a screen in front of your eyes, you'll need at least a 4K resolution screen.
Higher-resolution displays will also help lower the cost of lower resolution panels.

Newsprint are somewhere around 300 dpi. So we fiannially got a display where you can actully read the small print. Like so many websites llike to use tiny print. :-/

Now they will use even finer print.
When will business that places fine print on their business announcements be seen by the public like a job seeker wearing a bandit mask would be seen by a hiring manager?
Every time I see gray areas on a business communication, the hair along the back of my neck raises, and I wonder what kind of fast one the business is going to pull on me. I cannot read it without the microscope. If they are going to present me with something like that, they may just as well have smeared dog excrement over their business communication. Its received the same way.
I see grey print as a business's way of telling me that they aren't honest and upright, and they are hiding something.
