2014 is shaping up to be the year of 2K displays, with two Chinese manufacturers already confirming handsets with the super high resolution displays.
To start, let's clarify what we mean when we say 2K, as there are numerous resolutions that fall under this moniker.
When we mention 2K displays we are specifically referring to the Quad HD (or QHD) resolution, so called as it comes with four times more pixels than in a 720p HD display - that's a 2560 x 1440 resolution.
QHD is the next level up from Full HD (1920 x 1080), which is technically 2K as well, but we're focusing on the former here.
Why oh why?
Why are mobile manufacturers so interested in 2K displays at the moment? According to Michelle Leyden Li, Qualcomm's Senior Director of Marketing, the answer is simply 'us'.
"Consumers never seem to be satisfied and people want more and more things on their devices," Li explains.
"People are using their phones more for movies, TV, video... it's their own personal device and they want a beautiful experience."
It is that experience that is driving consumers to the high end flagship devices, with Apple's Retina display causing excitement when it was released on the iPhone 4. There's always an appetite for ever brighter and more high resolution displays, as it leads to consumers feeling like they're getting a next generation of technology for their money.
Evolution, not revolution
Looking back mobile displays have dramatically increased both in size and resolution, with the 3.7-inch 480 x 800 pixel screen on the Google Nexus One from 2010, for instance, now considered pretty tiny and low-res - coming in at 252 pixels per inch.
Today manufacturers are quick to highlight the resolution and pixel density of their new devices, with the likes of the Galaxy S4 coming with a Full HD 441ppi screen and the HTC One besting that at 468ppi.
In terms of pure numbers, a QHD resolution stretched over the 4.7-inch screen of the HTC One would give a whopping pixel density of over 800ppi.
We're unlikely to see a 2K display that small however, with LG's QHD screen (announced mid-way through last year) measuring in at 5.5 inches and giving you a 538ppi pixel density.
Compare this to the Nexus One with its WVGA screen and the difference that four years has made is nothing short of astounding.
The theory of implementing 2K displays is they'll provide smoother, crisper images, games should pop and movies should sparkle. Whether or not the extra pixels will actually help remains to be seen, given it's hard to quantify whether users are actually getting any visual benefit.
Apple currently believes that for its smartphones a density of 326ppi is sufficient, saving its 2K displays for the MacBook Pro with Retina display.
Big screens = big batteries
Anybody that has used a device with a larger screen will know that these tend to have an adverse effect on battery life, something that is driving handset manufacturers to put larger and larger power packs inside our phones.
This is something that the industry will react to, according to Li; "The industry always seems to solve issues. The 4K screens will require a lot of power, but the industry always seems to rise to the challenge."
