GSM Arena’s Screen Showndown: Nokia’s CBD AMOLED – best contrast, best colours, better sunlight readability than Super AMOLED!

November 29, 2010 16 comments

The meticulous folks at GSM Arena (Thanks Aymen Kanzali for the heads up to tips@mynokiablog.com) have compared the display technologies used in HTC Desire HD, LG Optimus E900, Sony Ericsson X10, Nokia N8, iPhone 4, Nokia C6-01, Samsung Wave and Galaxy S.

Basically, LCD vs AMOLED vs IPS LCD vs Super Clear LCD, vs CBD AMOLED vs Super AMOLED.

Nokia C6-01 with Clear Black Display (CBD) AMOLED proves to be a mighty contender, having best contrast with the Wave, followed closely by the N8 leaving iPhone 4 behind.

For sunlight readability, CBD is in first place with iPhone 4, BEATING the SUPER AMOLED buddies Galaxy S and Wave to 2nd and 3rd place.

On best colours – Super AMOLED? No guess again it’s Nokia’s C6-01 CBD with best colour rendition, edging out the two SUPER AMOLEDS.

Gallery: Nokia N900 vs Nokia E7 – Just how much better is CBD AMOLED over TFT LCD?

September 25, 2010 13 comments

Just how much better has the Nokia’s CBD AMOLED improved from the previous N900 TFT LCD (disregarding the N86 2.6″ AMOLED). The difference is startling. (note, N90 does have screen protector, but the colours would look pretty much the same regardless as it did so on the show floor N900).

N900 does ‘win out’ though on resolution, but the benefit perhaps with nHD is improved battery life with pushing around less pixels. Hopefully N9 has a bigger battery pack, eh?

The gallery below should link to full sized  12mp (though compressed somewhat) and to other photos where N900 is closer to the camera (so equalling reflection flare for N900 comparison).

The case of the Nokia N8 teaches us to be weary of extremely early, leaked ranting “reviews” of prototype, unannounced phones. Remember the lack of info o the powerful broadcom GPU? Which we now know is class leading? The putting down of the supposedly standard, nothing special camera? Which we know now to be the best ever on a mobile phone? And what about the screen?

“Nokia N8 with other smartphones that are being prepared for release, and I must say, this is ridiculous. For example, I see that the N8 is very cheap OLED display. In fact, Nokia calls it the AMOLED display, but if you compare the display with the Samsung HD i890 (1,5 years already on the market), Nexus One of Google and other phones, it is not so good. The display is not as great as Super AMOLED in Samsung…”

Samsung’s rare Super AMOLED is touted as the best in terms of screen technology. At least in certain circles. Bright, vibrant colour reproduction with superior sunlight visibility (a feature taken for granted in touch displays, particularly AMOLED and certain LCD). We have shown you that the E7’s performs great outside (regarless of unusual test parameters, I COULD SEE THE SCREEN IN SUNLIGHT)

Looking at a Super AMOLED display (Galaxy S) versus the Nokia E7, you can see a clear difference between Nokia’s own. More vibrant or over saturation? Whilst the E7 and C6-01 seem to produce colours more closer to each other, the N8 and C7 seem to still have an image that pops out slightly more than the Galaxy S. This may be due to white balance issues – who knows. Having seen the screens on these phones, one thing is true – they are FAR from the cheap OLED displays Eldar had described.

Renowned non-nokia enthusiats over at engadget have mentioned that the E7’s display is brighter and more vibrant than their beloved magical Retina Display with the E7’s clear black looking “SIMPLY Gorgeous, black levels are no joke. Samsung’s stranglehold on badass mobile displays was pretty short lived”.

Whether the N8 also has CBD is uncertain but some current N8 owners have described N8’s outdoor visibility to be better than Super AMOLED. Screen technology aside, you know it’s not just some cheap OLED display.

The only issue these screens lag behind in one aspect could be screen resolution. 640×360 vs 800×480 (e.g. N900, Galaxy S). On the upside, lower screen resolution benefits improved battery life. For sure, N9 will have 800×480 with CBD AMOLED, and awesome keyboard and 4″ screen at least all worked out.

HD Video and Gallery: Nokia E7 Clear Black Display Outdoor sunglight visibility test. It’s bloody good that’s what!

The major fear of AMOLED screens is their inability to be visible in sunlight. LCD screens can suffer similar fates too. My Samsung Camera for instance has a vampiric screen and dies when outdoors (hence these outdoor shots not being that good). But you can see that in very bright sunlight, the 4″ CBD  (CLEAR BLACK DISPLAY) screen of the Nokia E7 copes amazingly well. What’s more, you cannot really appreciate how great the E7 CBD screen looks through this camera and your computer screen. Truly blacker blacks, much more vibrant colours. You really have to see it in person. In a later post, I will show you indoor comparisons with the N900 and the difference is night and day.

People have ridiculed Nokia for not putting the latest screen technology on their phones and bigging up the “plain” AMOLED on the N8 (which, btw has decent sunlight visibility – not sure if there are similar polarizing filers ala C7). Now, with CBD on the E7 and budget C6-01 Nokia have something which is arguably comparable if not better than Super AMOLED.

Now in the video below, we bring the E7 outdoors in the morning sun to face mr Sun. The N900’s LCD TFT display is actually quite ok in the sun. The backlight sort of washes away till you have just a plain monochrome looking LCD display. The E7, there’s very little change – you can still see the rich colours outdoors. The only thing that would prevent visibility is the slight reflection on the screen.

As with AMOLED, the viewing angle is fantastic. The only thing that really stops readability are some slight reflections from the display, but they’re minimal (though surprisingly exaggerated by these pictures/videos)

In terms of resolution, the nHD isn’t that detectable, and looking surprisingly sharp given the big 4″ stretch. In a future post, you will see that the CBD screen looks like it’s printed glossy paper

TestMobile compares the Nokia N8’s AMOLED with the Samsung Galaxy S’ eye melting Super AMOLED. Though of course the camera could increase/decrease the differences (adjusting to brightness of one screen, affecting look of another), disregarding this, in the photo below you can see that the deep blacks and brighter whites in the Super AMOLED display.  I’ve seen both, but only individually so I can’t comment on comparisons, but both look fantastic.

Not to fear though as the N8’s AMOLED is not just a step above regular TFT LCD displays (see 5800 comparison) but is apparently head and shoulders above some current AMOLED displays (Eldar has mentioned N8’s display is superior to the Nexus one.) And apparently Samsung’s Super AMOLED will be exclusive to their own devices for a while – I don’t recall where I read that though, so perhaps unless you want a Samsung, we’ll all have to settle for great AMOLEDs

In AMOLED vs TFT LCD, AMOLED displays are brighter, have higher contrast, richer more vibrant colours and consume less energy.

In AMOLED displays, each pixel controls its own brightness, as opposed to having a unified backlight in TFT, so blacks can be well, blacker and whites can be whiter and the colours are richer and more vibrant. Plus by not needing a backlight, they can utilise less power.

Here’s the HTC Google Nexus One AMOLED vs Super AMOLED on the Wave (on top) VIA Mobile-Review.

The differences are much more obvious here, the Samsung is bursting with brilliance.

Comparison shot between the Nokia displays by All About Symbian. Apparently N8’s AMOLED is much better at outdoor visibility than N86/N85 which suffered from vampiric screens.

Nokia N97 vs Samsung Omnia HD vs Sony Ericsson Idou

Nokia N97 vs Samsung Omnia HD vs Sony Ericsson Idou

I was all set on the N97 until a three way ruckus broke out with the Omnia HD and Idou both diving in to join the Super-Mobile-Convergence-Device war.

Samsung and Sony Ericsson have extremely strong contenders, with:

The Omnia HD packing in a most gorgeous 3.7” AMOLED display, Symbian S60 V 5.0, 8MP camera and 720p 24fps widescreen HD video recording and

The code-named Idou, bringing in 3.5” widescreen display, as well as Symbian S60 V 5.0 and a 12MP camera with Xenon.

They all run on Symbian S60 V 5.0; even with their own specific interface ‘quirks’, they should all be pretty similar to each other. We’ll just have to see when they’re all at production level to see who makes the most to bring the best user friendly and innovative interface.

Is the 32GB of memory and physical keyboard enough to keep you from straying to the Samsung or Sony-Ericsson camp? We’ve seen most of the wow features on the N97 along while ago from the aged classic that is the N95 announced in 2006! On-board GPS, A2DP, 3G, HSDPA, WiFi, 5MP Carl Zeiss camera with LED flash, 3.5mm audio/tv out jack (most of which the mass public easily overlooked). Whilst the N95 was ahead of its time for quite a while the N97 which hasn’t even hit the shops is already flanked by two other very powerful rivals.

It seems it won’t be long until the hardware battle becomes saturated, all phones being more or less identical in shape, size and features where everything will come down to who’s providing the best software, online services and community/ecosystem interaction.

So, in this combat of flagships, do any pack enough artillery to sink the infamous iPhone? Or will that be accomplished by the elusive Palm Pré, or perhaps an Android?
