According to recent chatter, the Samsung Galaxy S5 is rumored to debut with a 2,560x1,440-pixel AMOLED display.
At a upward of 560 pixels per inch, this "2K" resolution is unlike anything we've seen from Samsung. But as terrific as this sounds on paper, it pales in comparison to what's around the corner. Strap in, kids, Samsung's already working on an AMOLED UHD display capable of 3,480x2,160 pixels. In other words: 4K smartphones.
Samsung this week revealed (translate) at the Semiconductor and Display Technology Roadmap Seminar 2014 that these 4K smartphones with pixel densities of 820ppi are on the horizon. Given that we've yet to even see 2K smartphones take off, we're likely a year or more away from the next generation.
It's hard to imagine why any hardware maker would bother squeezing this many pixels into such a small display size. Truth be told, most people I've encountered aren't able to discern the difference between 720 pixels and 1080 pixels in a smartphone. Tablets? Sure, I get that. When you're talking about 10 inches of screen real estate, it makes more sense to push these boundaries.
Although we might not see these screens for another 12 to 18 months, we may start glimpsing prototypes popping up at various events. IFA, which takes place in the fall, could be the first time we see such high-resolution images packed into 5-inch displays or greater.
