The Samsung Galaxy S IV is launching next week, that much is certain. Everything else, including its processor, its shape and its screen technology is largely up in the air, even though everyone seems to have opinions on the matter.
The latest rumour surrounding the Galaxy S IV is a fairly new AMOLED screen technology called green PHOLED, which the company has been producing in relatively small quantities since early 2012. The process uses a phosphorescent material made of green and yellow parts, which last “tens of thousands of hours” longer than the equivalent blue PHOLED products and are up to 37% more energy efficient than traditional AMOLED displays.
Such application on the Galaxy S IV could lead to “all-day battery life” Samsung executives boasted was coming in the next generation of smartphones. Battery life improvements haven’t scaled with the rest of the smartphone industry, leading to larger devices and bigger battery cells rather than more efficient applications. It’s expected that if the Galaxy S IV comes with an Exynos 5410 SoC, battery savings will need to be obtained from alternate sources.
The GS4 may also boast “floating touch,” similar to what Air View accomplishes on the Galaxy Note with the S Pen. Users may be able to hover their fingers over a folder, for example, to peak into its contents.
