Subpixel density - Galaxy Note II Q&A, Help & Troubleshooting

Hey Everyone,
As we all know, the Note 2 is a 5.55" inch screen and has 10% less pixels, leading to a 7% lower DPI. (264.5 vx 285, roughly).
My question is this, though: Given that the new pentile arrangement is RGB and not RGBG, doesn't that technically mean we have
a significantly higher subpixel density?
Isn't the old subpixel count: 1280 * 800 * 2?
and the new one: 1280 * 720 * 3?

Yes. Yes it does.

Wait....so the PPI is higher because of RGB and not PenTile?

if you do a simple ppi calculation , without taking into consideration that the note 1 is pentile , note 1 has a slightly bigger number of pixels per inch , but that is a pentile , not an rgb arrangement .

267ppi on the new Galaxy Note II. BUT, with non-pentile arrangement it will 'appear' to have a sharper image quality.
Even though the screen is .2" larger diagonally, it only has a 2% larger surface area.

I am waiting for the 32/64 gigs titanium grey to be available at emag Romania sometime at the begining of november .

The PPI is lower for the Note 2. BUT that's only because the Note 1 cheats the PPI by only having 2 out of 3 of the sub pixels in a traditional screen. This is one reason why the HTC One X's 720p screen (IPS LCD in RGB) looks significantly sharper than the SGS3 or even the Galaxy Nexus's 720p screen (OLED in Pentile).
Even though the PPI may drop slightly, you'll have significant clarity improvement especially with text and hardlines like in what a webpage displays. On the other hand, one may not notice the difference when looking at pictures or viewing movies.
The new Note 2 will have LONNNGGG awaited RGB OLED. No other phone that has OLED has had an RGB Matrix [Edit: ok, I mean HD OLED displays]

Retina Display + WP7?

This is one of the things that always comes up to my mind when I'm using my Samaung Focus and iPhone 4, what if my Samsung Focus had a Retina Display?
Or if iPhone 4 had three buttons and WP7
If the Samsung Focus had a retina display it would have a higher screen resolution.
please, lets stop using merchandising bs terms, its just a higher res screen, its not a new technology, its just a buzz word.
i have a samsung focus too, and i would reall really like it to have a higher res screen and RGB configuration, but not at the cost of changing from SAMOLED to IPS
Man, my focus with a lousy 3.5" screen would be terrible. What I want is WP7 on one of those new 4.5" super amoled + displays they're gonna put on that android phone they're making. That'd be the cheese, right there.
800*480 OLED with normal sub-pixels is good for phone sizes.
Text is most important and with normal subpixels you can turn on cleartype and have a boost in effective resolution. At 800*480 I think it's good for both images and text.
Pentile has lower actual resolution and doesn't have OS sub-pixel support.

It's a bit more than a higher res screen. It is LCD tech but it has a viewing angle that is as good as OLED. There is no loss of detail or washout at angles...extreme angles.
The thing though, is that I've never had a situation where I was using my phone and needed those types of viewing angles. As long as the phone is readable from a 100-120 degree viewing angle is seems like it's good enough for me.
The iPhone's viewing angles are good, but the screen size IMO worked against it for situations where the viewing angles would be a saver (showing stuff on your phone to others).
Also, the iPhone is still not that great when viewing it in direct sunlight, although it is better than some other LCD panels.
The Pixel Density is the biggest thing about the screen. It makes text, pictures, and even video look better than on lots of other lower-res phones...
Yeah, the screen size is on the smallish side. I wish Apple would consider a 4.3 being the minimum size. But I'm finding other things about the iPhone screen (the whole screen - LCD and plate) that really make up for size deficiencies. I think Apple is using the Oleo-phobic tech on the iPhone because it is so much easier to move your finger across it than on other displays. I have Fruit Ninja on both my iPhone and HD7 and slashing the fruit is painless on the iPhone. Slashing the fruit on my HD7 is a bit of a chore because the finger want to adhere to the surface...like the squeak you get when running a squeegee over a clean pane of glass. The touch response seems to be a bit more accurate on the iPhone, too. But that is likely due to the coding of the game and nothing to do with the HD7's tech.
I think MS just simply ported FN to WP7 without even optimizing it because the display is squished rather than having the proper aspect ratio (a circle being oblong...like a football...rather than a true circle).

You are just talking about IPS panel.
iPhone4 and iPad do use IPS, but iPod Touch 4 does not have IPS. However Apple still call it "retina" display, so the term "retina" just means the 960X640 resolution.

True, it is IPS LCD, which gives the best viewing angle among LCDs. But the main thing with the "Retina display" is the pixel density. Here is an excerpt from Wikipedia explaining the iPhone 4's display:
"The display of the iPhone 4 is designed by Apple and is manufactured by LG. It features an LED backlit TFT LCD capacitive touchscreen with a pixel density of 326 pixels per inch (ppi) on a 3.5 in (8.9 cm) (diagonally measured), 960×640 display. Each pixel is 78 micrometres in width. The display has a contrast ratio of 800:1. The screen is marketed by Apple as the "Retina Display", based on the assertion that a display of approximately 300 ppi at a distance of 12 inches (305 mm) from one's eye is the maximum amount of detail that the human retina can process.[35] With the iPhone expected to be used at a distance of about 12 inches from the eyes, a higher resolution would allegedly have no effect on the image's apparent quality as the maximum potential of the human eye has already been met. This claim has been disputed. Raymond Soneira, president of DisplayMate Technologies, said in an interview with Wired Magazine, that the claims by Jobs are something of an exaggeration: "It is reasonably close to being a perfect display, but Steve pushed it a little too far." Soneira stated that the resolution of the human retina is higher than claimed by Apple, working out to 477 ppi at 12 inches (305 mm) from the eyes.[36]
However, Phil Plait, author of Bad Astronomy, whose career includes a collaboration with NASA regarding the camera on the Hubble Space Telescope, responded to the criticism by stating that "if you have [better than 20/20] eyesight, then at one foot away the iPhone 4’s pixels are resolved. The picture will look pixellated. If you have average eyesight, the picture will look just fine.

Hang out for the new organic display tech. It sounds like each dot can be any color, rather than having each pixel made up of red, green, blue separate dots. If this is the case, the definition will shoot through the roof.

Such a screen size would be appropriate only if they change drastically their UI. Just think where usually are the main navigation controls on the iPhone - on the upper side of the screen. I am struggling to navigate comfortably with one hand on 3.5”, cannot imagine how can do that on bigger size. So much for the vaunted apple UI…
What is the highest resolution that WP7 supports? It seems strange that even Samsung do not want to increase the pixels on their new models announced at MWC. I feel WVGA is too 'basic' and not as pin sharp.

Sure, it's all about the pixels. Steve also mentioned that the limit for what the human eye can se is 300ppi. Therefore, we already have a bunch of "retina"displays around, and also have had for years. Among them, The Sony Ericsson Xperia X1 from 2007 had a ppi of 320, if I remember correctly. Toshiba had an device many years ago with ppi 311.

was the toshiba device the e900 series? i believe it was a 3.2 WVGA screen, so it had a high pixel density on a mere 3.2 inch screen. Correct me if i'm wrong.

Pixel Density on NG 4.65" OLED Pentile screen size

http://www.flatpanelshd.com/news.php?subaction=showfull&id=1319022037
that is a very technical yet interesting read.
This has been discussed to the death in the Galaxy S days.
Galaxy S and Nexus S has the same tech in it.
I think they looked fine.
If you have to calculate the pixel density like this, what does the Nexus S has with it's 4" 800x480 display? 150ppi?
Looks interesting will have to see one for real now hopefully soon

The PentTile AMOLED displays look great with pictures, video, etc, especially with the excellent black levels. However, for text it's not so good. I have a Galaxy S and the PenTile display looks really bad at times. Text looks tinted, and red text on black or just red on dark backgrounds in general? It looks like it's hovering above the display, horrible...
Sure, the GN has a smaller screen than the Galaxy Note and therefore a higher DPI, but I'm not so sure it's enough to hide the weaknesses of a PenTile display.
Hopefully someone will get their hands on one for a proper test of the display.
Hey look! Another AMOLED display and another site found out about PenTile RGBG vs. RGB or "Real Stripe"!
Hardly something new, that's been around since the first Nexus One and they don't break with tradition. Nexus One, Nexus S and now the Galaxy Nexus, all have a PenTile matrix.
Yes, PenTile RGBG matrix offers less sub pixels and still PPI and resolution are based on "pixels". That might not be ideal and there will always be PenTile haters counting sub pixels one by one. But unless Samsung can produce 300+ PPI AMOLED displays with their "real stripe" method it's either PenTile or LCD.

the nokia phones do not have the pentile matrix displays, nokia orders samsung oled screens with true RGB subpixel layout. however nokia struck that deal, likely paying more per screen (?), is a mystery because even samsung themselves who make the screens use pentile thru the years...while nokia got the true RGB OLED screens.
this includes nokia n8, n85, do not have pentile.

That second article is a more realistic view of how pentile performs in real life.
Most importantly, take a look at everyone's initial impressions of the screen, and check out the clear amazement in almost all of those articles, it seems that these new nay-sayers are very much based on prior conceptions, rather than real world performance.

The icons and text look okay in the running video. Not sure what the distance is.
More interesting were the benchmarks in the video. What were they, and how do they compare with the same benchmarks on some of the flagship devices from the last three months?
Also there seems to be a little bit of rendering/painting delay at 3:55-4:00 when the user tries to pinch an enlarged section of a web page, though that might be expected behavior. Was surprised to see that since the reported Sunspider and V8 benchmarks for the Galaxy Nexus handily beat the SGS2.

[Q] Ppi pixel density

According to gsmarena wave 2 has more ppi pixel density than galaxy s
Is it means that wave 2 produce little bit more sharper image than galaxy s though galaxy s has better screen technology. I need to know what does exactly ppi pixel density means..
Best Regards !!
PPI means pixel per inch, so yes Wave 2 has way more sharper image than Galaxy S.

[Q] Screen

hey guys i was thinking about getting a galaxy but my only concern is the screen i have like an ocd thing about pixelation and i heard their hardly isnt any on the galaxy note 2 although it has less pixel density as well, well maybe at least compared to the gs3. how are you guys liking the new screen?
I came from the high ppi iPhone 4, from 326 to 267, and I'm very happy.
I'm not as OCD as you, but I'm still OCD, and with all the features of the Note 2, and humongous battery, I am definitely pleased.
1280x720 > 960x640 anyday, albeit lower ppi.
If you mean, clarity of small text. I can read full page pdf docs with smallish writing, in portrait mode. Dont have to zoom in. Iphone would be just a blur. The massive screen more than compensates for effectively tiny ppi differences. Wait till we have 1080p on 5inch displays then it will be more noticeable.

No problems here either. I've owned all of At&T's recent top end phones (iPhone 4, Note 1, One X, and S3 to name a few) , and I think it's the best screen on a mobile device to date. PPI isn't the end all be all. The bigger the device the greater the viewing distance is. The greater the distance the less PPI really matters. Can't really compare a 4" and 5.5" device on PPI alone.

that doesnt really explain it. note 2 may have lower pixel density, but it makes up for it with an overall higher subpixel density, which is the reason why our note 2 screens are sharper than our note 1 screens. theres less blurring of pixels because of the full rgb matrix on the note 2 compared to the pentile display of the note 1 where adjacent subpixels were borrowed.
pls help me to fixed my blurry screen samsung galaxy note II. i dropped in water of stlesst 4 sec. snd when i turn on blurred
