Samsung's AMOLED displays are a thing of pride for the company, and for good reason too. While some users prefer LCD panels over how AMOLED works, no one can deny that Samsung can make a truly beautiful display. Samsung was a little slow coming to market with a 1080p display, being behind some competitors by almost 6 months by the time the Galaxy S4 came out, it looks like they might be trying to rectify that by pushing QHD 2K displays before anyone else. While we thought LG would be first out of the gate with a QHD 2K display on their upcoming G Pro 2, it looks as though that device will "only" be 1080p, so that still leaves us wondering if the Galaxy S5 will be the first QHD 2K display or not. At the Semiconductor and Display Technology Roadmap Seminar 2014 today Samsung announced that it was producing QHD 2K displays, which are capable of displaying at a resolution of 2560 x 1440 pixels. That's 4 times the number of pixels on a 720p display, and nearly double of a 1080p. Looking at a 5-inch display as would be seen on a Galaxy S phone, we're talking a jump from the current 440 pixels per inch to 560 ppi. Samsung didn't say whether or not this display would be on the Galaxy S5 or not, but we imagine they'd want to debut a big display leap with a big new phone.
What's more Samsung also confirmed development of UHD 4K AMOLED panels which are capable of a resolution of 3480 x 2160 pixels. Put that on the same 5-inch screen and you end up with a rather insane 880ppi, which is considerably beyond what we seen on current smartphones and other devices. That's a whopping 4 times the number of pixels on a 1080p display. The question now is, do we really need these sorts of densities on small mobile displays? At this point most people can't see the density increase that's been seen on 1080p displays at the size most mobile displays are, and going forward the difference will likely become more and more minimal. Our eyes can only see so much detail, and generally somewhere around the 360ppi mark is considered a "perfect image" when being held at a standard length away from your eyes. Samsung does love to use a pentile matrix pixel configuration in its displays though, and this naturally creates a seemingly less dense picture, so higher resolutions tend to make a bigger difference on Samsung displays than others might. Samsung also talked about its plans to release an 8k UHD TV, which as the name implies is even more pixels than 4K, sporting an eye-popping resolution of 7680 x 4320 pixels, or well over 32 million pixels total. That's a pretty big step up from 4K's 7.5 million, which makes us wonder how far Samsung will try to take the mobile display market in the future.
