Sony Unveils Smartphone With 4K Screen
An anonymous reader writes: Sony has taken the wraps off its new Xperia Z5 Premium smartphone, which has a 5.5" display that operates at 4k resolution. "The company acknowledged that there was still a limited amount of professional content available in 4K — which provides about four times the number of pixels as 1080p high definition video. But it said the Z5 Premium would upscale videos streamed from YouTube and Netflix to take advantage of the display." Sony's answer to the obvious battery concerns raised by such a pixel-dense (808 ppi) screen was to use a 3,430 mAh battery and memory-on-display technology. The video upscaling can also be turned off to decrease battery drain.
That type of resolution lends itself very well to doing things like lenticular 3-D. I know people often don't like lenticular, but that's usually because it's done so poorly so often. Well-done lenticular is amazing to see and is not a strain on the eyes. If glass lenticules were built into the display itself, and were appropriately sized and spaced, it could be impressive.
There are other interesting technologies too that could be done, such as barrier-screen - that could be implemented by LCD over top of the display - which would be less intrusive and could be turned on/off.
I write software for these applications - I would drool over a screen that had 808ppi!
I used to have a sig, but I set it free and it never came back.
They say 8k is the ultimate target for a VR headset.
