Full HD on smartphone screens is close to default, and now lurks in the wings, but 4 k 4 k is too much for a smartphone?
Concepts such as HD and Full HD is now well-known words, when we are talking smartphone screens and monitors in General. But a new term is to sneak up on the market: 4 k, covering over a monitor with even higher resolution one case is with HD and Full HD.
4 k UHD (Ultra high definition) has a resolution of 3840×2160 pixels in 16:9 format, which is 4 times more than is the case with Full HD, where resolution is at 1920 x 1080 pixels.
Samsung has already announced that they expect to present smartphones with 4 k in 2015, and there are many indications that more manufacturers will follow suit.
For large TV screens give it maybe good sense that low resolution even higher than it is today, but what about smartphones, where screen size is substantially smaller than a TV screen?
We asked Rasmus Larsen from our site, on the super high resolution of 4 k makes sense on a smartphone:
“I believe it is in the over the edge, and it looks a bit like a parameter manufacturers use to sell their products. It can compare a bit with the megapixel-race, having previously been around cameras ”
“To push so many pixels into a tiny screen does not make sense, since the eye must be very close to the screen to be able to see the difference, and since most don’t keep their smartphone right up to your eye, you will not benefit from the high resolution,” he said.
He also believes that 4 k will be “overkill” even on conventional tablets with a typical screen size of about 10 inches.
But how much should the producers then press screens?
Rasmus Larsen believes that Apple is good in goal with their Retinaskærme on iPhones that have a solution where you want it to be. On the other hand, Apple can improve their screens at other points.
“You can’t uniquely categorize a screen as good, just because it has a high resolution. There are other thing producers can do better, as for example the ability to reproduce colors properly or good contrast “he says.
He also think that race around the resolution of mobile screens will die out within a few years, as consumers simply becomes saturated.
When will need to assess the quality of the screen, there are many other parameters that come into play than just the number of megapixels. Pixel density, the person’s eyesight, the distance to the screen, the amount of light and several other factors are also important, why an overall comparison with all these parameters will be incredibly complex.
Do you want to know more about the resolution and the ability of the human eye to perceive the world, you can get on the right track with this video, which overall asks the question: What is the resolution of the eye?
