Fresh rumors about Samsung's Galaxy S4 hint at new screen technology and floating touch input for the flagship Android phone.
According to SamMobile, an inside source is saying that the Galaxy S4 will use green PHOLED technology for its display.
PHOLED uses phosphorescence instead of fluorescent light like traditional OLED displays, making it significantly more energy efficient.
The technology has so far been implemented in displays that use PHOLED for one or two of the red, green or blue light spectrums.
The green PHOLED would cover the green-yellow spectrum, lowering the display's power needs.
Look and don't touch
While the rumors suggest that the Galaxy S4's screen will be more energy efficient, there are also hints that users will be touching the screen a whole lot less.
The same inside source indicated that Samsung will use floating touch technology in the Galaxy S4, letting users hover their finger over the screen to for actions like previewing emails and thumbnails without tapping to open them.
Samsung used similar technology in the Galaxy Note 2, which used the S Pen to hover over the screen for the Air View feature.
Floating touch joins eye control through the Smart screen suite as a rumored new interface for the Galaxy S4.
Samsung is expected to fully reveal the Galaxy S4 at the Unpacked event, scheduled for March 14, and TechRadar will be there to bring you all the details on Samsung's new flagship smartphone.
