There are a few areas in which smartphones have continued to improve and push the boundaries of mobile technology, such as CPU power, screen resolution and graphical grunt. One of the most user-facing improvements in recent years though, has been how densely populated with pixels our smartphone displays have become. Google and Samsung made waves when they announced the first 1280 x 720 display with the Galaxy Nexus – now we've got 1080p displays becoming the norm, and display technology is advancing just as fast as everything else.
Of course, all the companies behind such advances will be looking to the future, and it stands to reason that in the next year or so, another wave of high-density displays will be on the market. According to ETNews, smartphone displays will soon reach 500 ppi with resolutions of 2560 x 1600, that's basically bringing the Nexus 10 display down to fit comfortably in your pocket. For those that get all excited at the prospect of fancy new acronyms, that's WQXGA resolution. 5-inch displays at the Full HD resolution of 1920 x 1080 feature 440 ppi and it's said that next year could be the year of the 6-inch 2560 x 1600 panel.
Korean and Japanse companies are already working on new technologies that could enable such high-resolution displays, technology such as Low Temperature Poly Silicon or LTPS is being worked on. LG Display will continue to use their AH-IPS technology to get that 500 ppi number, while JDI (Japan Display) and Sharp are also taking steps to reach the dizzying number of 500 ppi, there's even talk of Sharp adopting their IGZO technology to make sure that such high-resolution panels don't have an adverse effect on battery life.
All of this sounds great and all but, isn't 1080p good enough? Do we really need to continue cramming pixels into our pocket displays? It's said that there are only so many pixels our eyes can actually appreciate on a display and so the question really is; do more pixels always equate to a better display? It isn't about time that these companies start making improvements in color, contrast and so on? So far, it looks like Samsung are the only company more concerned with how a display looks rather than how many pixels there are in the display.
