Sony is still not ready to launch Quad HD smartphones


Most of the relevant Android vendors already have at least one smartphone with a Quad HD (1440 x 2560 pixels) display, but Sony isn't included here. Last year, Sony defended its decision not to make a Quad HD screen for the Xperia Z3, and this year the company is, once again, doing the same thing - this time in regards to the Xperia Z3+ (pictured above).

Jonathan Lin, general manager of Sony Mobile Taiwan, recently talked to Focus Taiwan, saying that the company will launch Quad HD smartphones only when it "can make significant improvements in display quality and digital image processing technology." At the moment, Sony doesn't believe that screens of around 5.5 inches can really benefit from Quad HD resolutions.

Of course, a Quad HD display is more power hungry than a 1080p one, and negatively impacts battery life. With a 1440 x 2560 pixels screen, the Xperia Z3 and Z3+ would probably not be able to provide 2 days of battery life. The long-lasting battery is one of Sony's flagships' highlights, and it's no wonder that the company doesn't want to give up on this just for the sake of a higher pixel resolution (when 1080p is still perfectly fine).

What do you think, is Sony doing the right thing by not joining the Quad HD party yet?

at least someone has some good sense. QHD is the most pointless thing in the world on screens that small.

I think QHD resolution is pretty much useless under 6 inch screen. But if they do use QHD resolution for 5-5.5 inch phone they should wait at least 2 gen. I believe SD820 is perfect capable for QHD resoution but Imagine a phone with SD820 with FHD resolution. Super performance and great battery life.

Well, if Vivo could launch a QHD phone (first one perhaps) back in 2013 with SD800, SD810 should be good enough for QHD phones in 2015. Now if they want to use QHD, it should be RGB as pentile QHD brings pretty much nothing over 1080p RGB other than the marketing stuff.

Yes, the sharpness of pentile QHD panel and RGB FHD is pretty much the same. So its even more justifiable to not to jump to QHD resolution. RGB FHD resolution is more than enough for a 5.2-5.5 inch screen. SD810 is great for FHD phone (great gaming experience), SD820 will be superb for FHD phone. I would personally like Sony to stay FHD for SD820 it will not only give better overall performance but it will also ensure great battery life. Go for QHD resolution for whatever comes after SD820.

I totally agree with you and that's exactly why the compact versions are actually faster than the regular Z models. An SD820 1080p phone would be ideal for me too! But most customers care only about the numbers. Sony will have to go QHD sooner rather than later. What's more ironic is that they have to go RGB QHD and take a bigger hit on the battery life. Quite a dilemma!

The often perpetuated myth, is still a myth. Our eyes are much more sensitive to green than blue and red, which is why a higher resolution in the green channel has a much larger visual impact than the same increase in the blue and red channels. And a 1440P Pentile screen still has 78% more green pixels than a regular layout 1080p screen, hence higher percieved sharpness.

And here's the evidence to support that claim, from left to right: G4 1440P - S6 1440P Pentile - M9 1080Phttp://oi57.tinypic.com/t9w5zb.jpg

LOL at your math & myth. 1440p petile has ~25% more green s-pixels (that's nowhere near your inflated 78% claim) and ~5% less red & ~5% less blue s-pixels compared to RGB 1080p PA already did a comparison. Turned out pentile S6 can't render simple white that a $50 phone can do all day long.

well I totally disagree with you regarding pentile QHD and RGB FHD... I had pentile QHD note 4 and RGB QHD vivo xplay 3s and RGB FHD huawei mediapad x1 at a time... I put all these three together to check the quality of the display and nothing can match the clearity, sharpness and true color reproduction of Note 4's display... note 4's pentile SAMOLED QHD display's superiority is far too great to match by any LCD at the moment(my experience)... Moreover, vivo xplay 3s has visibly better and sharper QHD display than FHD of huawei mediapad. Please, do keep in mind that both devices are 6inch and above, where you can easily notice the difference between QHD and FHD. Now I will agree with SONY for sticking with FHD for small devices... We cannot identify any difference between QHD and FHD on a screen size 5.5inch or below, same like we cannot identify any difference between 1080p and 720p on a display size 4.5inch or below

That's not true, the Galaxy S6 is way sharper than the HTC One M9, and just as sharp as the LG G4. Just look at comparisons on the web.

how will you explain the note 4's battery life? and the S6 with small battery that can compete with most 1080p screen with bigger batteries?

Best display, best optimization on Android, best soc, power efficient amoled, best camera. That's s6

Pentile amoled: it's as sharp as normal fullhd, so it's nothing special

Hmm... I think someone by the screen name of bur60 need an eye specialist... please dont be fooled by screen pixel/subpixel mathematics... in real life, in practical use, the display quality of SAmoled is leading the display herd... why not experiment if it doesnt hurt? take a note 4 and put it side by side, one by one with all the devices available in the market. Then you will realise, what the pentile SAmoled is

Sony Xperia Z3 compact is one of the best phones when it comes to battery life. You can go and see by yourself that Z3 & Z3c have better battery life than SGS6 or SGN 4http://www.phonearena.com/phones/benchmarks So that proves that with lower resolution higher battery life comes.

ofcourse, there is no rocket science in it... low resolution = better battery life... Even there is no need to paste a link to prove this simple and common point, However I appreciate the effort... Since you have replied to above arguement and there is a point in above arguement... and a very important point which you failed to realize and I would like to clarify, in above argument they are talking about power consumption of QHD and in reply the power efficiency of SAmoled QHD. Which is greater than LCD QHD... if you want to talk about 1080p or 720p then ofcourse they will be more power efficient... but if the question of QHD arises then SAmoled QHD is a better and efficient implementation

Thanks for clarification, he didn't mention Amoled at all, unlike the above comments that isn't related to this.That is why I didn't get it. I agree with you on SAmoled and it is better for battery than LCD . (which one is better in general I can't say) FHD Amoleds are the best solution for battery :D

yes because battery matters more !

If they want to use a power efficient QHD panel, why can't they use AMOLED.

Amoled is crap.

Maybe 3 or 4 years ago... Can you name any current downsides to AMOLED?

Power savings go down when browsing the web or using other apps with black text against a white background. There is still an issue with burn in but the way the display gets cycled it shouldn't be a problem nowadays and the only burn in I see now is phones on display at stores or careless owners that don't shut off the phone if it gets frozen.

Power savings go down? Meaning normal usage? Amoled display phones get great battery life and can be more power efficient than LCD displays. Lots of apps offer dark themed versions and most web browsers offer an inverted view. Burn-in is no longer an issue unless you hold onto your phone for 3 or 4 years. I doubt 90% of people use theirs for more than 2 years. The scenarios you offered are more than preventable.

Oversaturation and burns (yes they still occur if you leave a still image anywhere on the screen. Every amoled device still has the problem, some less than others.)

AMOLED is not crap. They used to be crap but not anymore. Amoled is on par with the best LCD even surpass LCD in many aspects. But it is also true that Samsung don't give the best AMOLED to their partners, they keep the best for themselves and give a crappier version of it to their partners.

whats wrong in keeping the best for themselves? its a good move and pergectly fine. Do the rotten apple give ios to others? do the apple give cyclon chips to others? do they sell their touch id technology? Instead apple bring law suits on minor things if any other OEM take an idea from them. Apple is more hidious than any other company
