2014 is by now widely expected to be the year that flagship smartphones will come with WQHD (2560×1440) displays. With MWC 2014 just around the proverbial corner, the first announcements may come in less than a month. If further proof was needed, Samsung Display confirmed this week’s Semiconductor and Display Technology Roadmap Seminar 2014 that it was getting such displays ready. It also revealed that it was already working on UHD (3840×2160) AMOLED displays as well.
A 5-inch Full HD (1080×1920) display gives you about 440PPI (Pixels Per Inch). At QHD, that jumps to 560PPI. At UHD, it stands at 860PPI, nearly double that of the Full HD displays our flagship smartphones sport today. To put that in perspective, most agree that even the sharpest eyes are not able to discern individual pixels on a smartphone screen (at a reasonable distance of about 30 centimeters) at about 500PPI (I’m being generous as well).
UHD or 4K resolution as it is also known is just starting to hit store shelves in the form of new high-end televisions and computer monitors. And while Samsung is busy trying to cram that down into a smaller display, it is also looking at 8K UHD (7680×4320) for the next generation of televisions.
It’s not certain that 2015 will be UHD’s year but the pace at which display technology is moving means that it could well be. Before then, it is likely that we will have a few more debates about whether we need such high-resolution displays on our smartphones or not. After all, even if we can perceive an improvement, does it warrant the extra battery power required to power such a display when battery life remains a limiting factor for so many of us?
Any takers for a smartphone with a UHD display as soon as it launches? Let us know below why or why not.
