A 4K screen on a phone is not a trivial change involves having to have a much more powerful hardware to keep moving with guarantees that amount of pixels, and also affects the autonomy of the team, but it is an inevitable trend, also driven by the virtual reality.
I explain apart from the virtual reality helmets that cost a pretty penny, there are many companies that want our phones are the eyes of those helmets, approaching the experience more affordable. Samsung and Google are the most interested companies it either with solutions cardboard, plastic well. But the reality is that they are functional, with phones that are already on the market.

The idea to cram more pixels into such a small space makes sense if we think in this new way, as a normal distance will not notice much difference, but Inboard start making sense that everything is well defined. Our news today has to do with a development of Samsung, oriented to this use.
Koreans have led the SID Display Week – a fair on screens – a panel of 5.5 inch 4K resolution, or what is the same, 3840×2160 pixels in the size of a normal phone. Nor is the first panel and nor will be the last, but it is very important that it is Samsung who wants to give visibility to the issue.
In a mobile or inside a helmet
We speak of a dot density of 806 pixels per inch, the better for use inside a helmet. For now it is only a prototype, but it is easy to imagine that will go to a new Note or Galaxy S, which will have as an ally a new Gear VR.
Or who knows, possibly panels are designed to include a virtual reality helmet, no phones involved. To give us an idea both HTC lives as Oculus Rift they have screens 2K, with 2160 x 1200 pixel resolution.

Samsung also boasts brightness levels, reaching 350 nits. The screen is also capable of playing 97% color gamut. What is different about this development with respect to other panels of the house is the implementation of a technology called “Bio Blue” which is supposed to emit less than the AMOLED blue tones of the house, potentially damaging to the eye.
At the same fair, Samsung has taken another technology called “Lightfield display” allowing represent a very special feeling of depth.
Sony did before with 4K
The first to give birth to a phone with the screen resolution, and sell it, has been Sony with its Xperia Z5 Premium, also at 5.5 inches. Then it has come a model more, but the reality is that it is an uncomfortable amount for most chipsets market.
