Subpixel density

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]
Pentile (7 pixles)
|RG|BG|RG|BG|RG|BG|RG|

[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's great. I've been debating on getting one but now that I have opinions I might go buy one now

Blurry?

My note 2 screen appears to be blurry as compared to my note 1 altough rich colors.

Maybe you have a bad screen. Because comparing to my dad's note 1, the note 2 screen is clearly better.
Also mines quite crisp for an amoled

Yes, note 2 got lower ppi than note 1 and the screen blur pixels together

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

screen question

I have a galaxy tab s 8.4 and a note 4, spec wise the screens are the same, but the tab s screen looks so much better, can someone tell me why, what am I missing?

The resolution is 1600 x 2560 pixels with ~359 ppi pixel density vs the not 4's 1440 x 2560 pixels with ~515 ppi pixel density.

Is the Screen Resolution of the Mate 20x Amazing?

I'm thinking of buying this phone. But I need to know hows the screen resolution. Is it amazing? Is it as great as the resolution on the samaung a70?

Both resolutions are FHD+
a70 has a 6.7 inch screen with 398 PPI
Mate 20 X has a 7.2 inch screen with 346 PPI
Technically a70 is a little sharper but hardly noticeable to the naked eye
Also, Mate 20 X's screen (18.7:9) is thicker compared to a70 (20:9)
All in all, from just a screen perspective it's better to get the Mate 20 X because you're getting a bigger screen with just a small reduction in pixel density. The quality is still amazing.

A70 is much cheaper. Maybe get a80 as a good comparison.
