Display Quality - 4.7-inch 1080p

The HTC One includes a 4.7-inch 1080p LCD display. I thought the HTC Droid DNA slash Butterfly was probably around the highest we would see pixel density go for a smartphone, turns out the HTC One is even higher, obviously, given its smaller size. The display is what HTC calls Super LCD 3, previous revisions were Super LCD 2. As far as I know this is an IPS display as well, Low Temperature Polysilicon (LTPS). Atop the display is a Synaptics ClearPad Series 3 S3202 with 10 point touch detection. This isn’t in-cell based on the presence of S3202.

I did some digging, turns out the display is curiously marked as being from JDI (Japan Display Inc) who also was behind the DNA and Butterfly display. In fact there’s even a press release from JDI about a display with those exact same specs (5.0 inch, 1080p, 443 PPI). Of course the One is even higher, 4.7 inch, 468 PPI, no doubt this is a different revision. Interestingly enough I believe Samsung display is also a secondary supplier based on the string I saw dumped.

For interested parties, this resolution and size puts the HTC One display in a category above xhdpi, the nascient xxhdpi Android density which is technically for 480 PPI but 470 PPI is apparently high enough to qualify as well. HTC internally defines the One as being 480 PPI to meet this threshold.

Subjectively, I find the HTC One display nothing short of amazing. The DNA already was incredibly high resolution, the One is even better. That level of resolution definitely exceeds my visual acuity, and is a sight to behold. When it comes to viewing angles, they’re excellent indoors and just about the same as every phone outdoors. There’s hardly any gap between surface and display with the One at all, it’s brilliant indoors and out. To say that 1080p on mobile devices has spoiled me is putting it lightly. In addition, 4.7 inches seems to be a nice middle ground in terms of display size — it’s close enough to 5 to not seem small, and not absurdly huge.

The HTC One includes a dynamic contrast function which can’t easily be disabled, as there’s no option in the display settings for it. There are obvious log messages which get dumped which reflect the dynamic contrast’s presence as well. This makes measuring contrast and black level somewhat difficult since it’s always adjusting brightness based on the content. HTC makes it pretty subtle, but it is definitely there.

Contrast Ratio

Brightness (Black)

Brightness (White)

The One goes nice and bright, at just shy of 460 nits. If you believe the contrast and black levels, it’s also incredibly contrasty. I suspect that real contrast is much closer to 1000 though than 1700+ given the dynamic contrast.

I did the usual thing and ran the One through our new-ish smartphone display calibration workflow. In the past I’ve been very pleased with HTC’s calibration, publicly I said that the One X was probably the best Android-landscape display I had seen for that generation, and the One S was by far the best I’ve seen SAMOLED calibrated and the most well controlled I’ve seen it out of the box, no joke.

CalMAN Display Comparison
Metric iPhone 5 iPhone 4S HTC One X Samsung Galaxy S 3 Samsung Galaxy Note 2 Google Nexus 4 HTC Droid DNA HTC One
Grayscale 200nits Avg dE2000 3.564 6.162 6.609 4.578 5.867 7.686 6.738 5.391
CCT Avg (K) 6925 7171 5944 6809 7109 8506 8108 8118
Saturation Sweep Avg dE2000 3.591 8.787 5.066 5.460 7.986 8.517 5.856 3.365
GMB ColorChecker Avg dE2000 4.747 6.328 6.963 7.322 8.185 7.531 6.687 4.656

By the numbers the HTC One is better calibrated (lower Delta-E is better in the table) than the One X or DNA, and the color space comes very close to sRGB out of the box. It is demonstrably better than the predecessor in every way, and amazingly gives the iPhone 5 a run for its money in saturation and the GMB color checker card. Inexcusable however is the 8000K+ white point, which is blue, although during use I never have looked at the One and thought wow this is really blue.


     


    


    


    

I think we’ve gotten to the point in the smartphone landscape where we have enough PPI, maybe a bit overkill honestly. There’s really no point in going much beyond the visual acuity limit, you could make an argument about nyquist and covering a few edge cases where the 50 percent square wave assumption built into 1 arcminute doesn’t hold up, but there’s no need to go much beyond this. Instead, now we need to get color accuracy tracking well and not drifting during a product’s lifespan. I think HTC continues to do a much better job than all the other Android OEMs, but only Apple is really taking things seriously here and taking the couple of dollar hit to have each panel calibrated. That said the HTC One’s display is a sight to behold, it is incredibly crisp and sharp in every condition you can throw at it.

    i am very interested in this HTC One phone but i am also interested in the RAZR HD maxx as well but it does not seem to be much of an upgrade from the razr maxx i currently own

    issue i have is will it Really last an full day on one charge of real world use, as i have seen a lot reviews of phones and the battery life part of the reviews to me seem an Lie quoting Twice the real world battery life, yours included as well i got the HTC One X (uk) and it was an Joke to use as it would not stay on for long (only one that gets close to correct battery report is the razr Maxx and the Razr HD) only one site seems to side with poor battery life or currant smartphones correctly and that is "theverge" but other sites and other users do not like the site and tend not to agree with there results

    on the razr maxx that i own it can go nearly 2 days or 1 day if i go nuts on it, i really love HTC phones but with the Joke of an phone HTC one X (its like an portable gaming laptop your lucky if it lasts 2 hours on battery) that got rid off in less then an month of owning it, every phone i have had has been poor battery life, i had the G1 and HTC desire (the first one) but i could use an extended battery on them yes it made them an brick but it lasted long time

    i do really like HTC phones but as all other smart phone makers are doing still is neglecting the battery size so it can Just about make it last an day if you use it lightly

    but to add this is an running battery life with any one person i have come across who has got smart phones Reply

    Is the period key broken on your keyboard? Nothing but run-on sentences. Reply

    was bit long my bad, just i find battery tests that sites do seem to be more then half what is reviewed as to why i norm just divide it by 2.3x ish to get real world results

    there needs to be a real world tests as well (facebook, twitter, skype, youtube, browsing so on), as there is no way you can get the times you see on review sites (HTC one X international version and the iphone is good example of unrealistic battery life is when reviewed)

    Interesting that you acknowledged that you had not punctuated your post you then made another post and again you didnt use punctuation it is interesting i was going to ask you why you did it i have decided not to do that that would be redundant i am of the opinion that you are going to continue to post this way as a result of that i am going to disregard your posts in the future .

    at least ieexgx has punctuation in his sentences, anybody should be able to tell when a sentence starts and ends without thinking about it Reply
