With Android on every display from a low-end smartwatch to a ultra-high-end smartphone, Google drafted a clever way to make sure only the correct file image resolution was used on certain devices, to maximise memory space and make sure the user has the best experience.
On Android 4.3, Google has added yet another ultra-high resolution, supporting 4K displays. Google engineer Dianne Hackborn said this will be for 4K Android TVs, but we believe it is merely another move by Google to allow manufacturers to stretch the limits of displays on smartphones and tablets.
Previously, there were five hardware DPI categories:
- Low DPI (LDPI) = 120DPI (smartwatches)
- Medium DPI (MDPI) = 160DPI (low-end smartphones)
- High DPI (HDPI) = 240DPI (two year old smartphones)
- Extra High DPI (XHDPI) = 320DPI (last year top-tier smartphones)
- Extra Extra High DPI (XXHDPI) = 480DPI (this year top-tier smartphones)
The newest edition is named XXXHDPI and will support over 600 DPI. Considering 4K has not even flooded the PC marketplace and barely scratched the surface on TV, it is hard to imagine we will see this explode on Android phones.
However, with the speed of display movement in the mobile industry today, we wouldn’t be surprised if Samsung, LG, Sony and other mobile manufacturers aren’t cramming as many pixels into new displays as possible.
This is good news for those that have always wanted to watch a movie on their smartphone, but the cost of innovation won’t be cheap and we wonder what the first 4K smartphone will cost.
