[Q] WVGA vs. Super AMOLED

Ok so I was about 98% set on purchasing the G2x/O2x but then realized it had a WVGA screen. Isnt that outdated?
I really liked the Galaxy S and above because of the SUPER AMOLED. I have an MP3 player with that screen (Cowon) and its great looking.
I am looking for comparison, if WVGA is fine and bright, perhaps comparison in sunlight, etc. I thought AMOLED was the next big thing and all phones would have it.

WVGA is the screen size, mate. It means 800x480.
For the screen, yes, it is not AMOLED which is brilliant to display black color but poor in direct sunlight. It is supposedly more engergy saving (but then you need to increase the brightness in sunlight)
The TFT IPS LCD that Optimus 2X has is very good indeed in my opinion.

Personally i prefer the screen on the O2X, i don't like the colors on the Amoled, not realistic at all

The IPS screen on O2x are brighter, sharper and with better colours than Amoled - its also better in the sun and have as good viewing angles as Amoled. The only thing where Amoled are slightly better is pure black. It's the same type of screen as the Iphone4 (actually its LG that manufactures the screen for Iphone4 to Apple) - except the Iphone4 screen has higher resolution.
You wont be disappointed about the screen on the O2x - it is very good.

Mate. LG screen clarity is outstanding, sunlight, clublighting, office home you name it. I run it with auto off and at approximately 20%. So brighter is available.
You will not be disappointed.

Thank you for all the responses and clearing up. I was lookiing everywhere for the info on what the screen was, it was strange because one site just said "WVGA" for g2x and the galaxy it said AMOLED so I wasn't sure.
G2x is now still at the top of my list =) I am deciding between this and when the Galaxy S II comes out, seems like slightly better hardware, but dont know other details

Indeed and amazing better as the Amoled from my HTC Desire S only the black isn't pure black in some cases but hence the vivid colors and the overall screen make up for it big time

I came from the Galaxy S to the OP2X, so I can report for you
The Super AMOLED of the Galaxy S is nothing short of glorious. Even though it uses a "pentile grid" subpixel layout, it's crisp and bright. It's even readable in daylight.
Coming the the OP2X and its TFT LCD, I was very pleasantly surprised. The screen has great viewing angles and almost no colour warping at high angles. The blacks are really deep, so the contrast ratio is much better than I was expecting. If I hadn't experienced the SGS screen first, I'd be utterly in love with the OP2X screen. As it is, I'm 'merely' very happy with it

Having spent 4 days using an S-LCD Nexus S, then going back to my AMOLED Nexus One, I can say that the S-LCD is miles sharper than the AMOLED. OK so you do lose out on a bit of black, but not being Pentile does make up for it.

Thanks, a viewpoint I was looking for =) I guess that eases me. Yeah I was concerned about the viewing angles, crisp of the colors and daylight viewing.

Do yourself a favour and go somewhere where you can look at the O2x screen live - anyone having concerns about the screen should do that - and be pleasently surprised
It really is very good - high contrast, high brightness, excellent colours with no banding, excellent deep blacks (for an LCD), good viewing angles etc. - viewing pictures of real life scenarios on the screen is a treat.
It actually makes my Desire Amoled screen look slightly dull

I sit on a bus and can read just fine. And its been really sunny where i am at the mo.
This screen is fantastic compared to my HTC Hero lol!!

The screen is really nice. Im very convinced, also in bright sunlight I can read the screen well enough.

LCD vs OLED
I wish people would just stop using 3-4 letter abbreviations for screen resolutions. In the early days (80s and 90s) there only were a few of these abbreviations and they signified a lot more than just resolution, like color depth and graphics capabilities, but now they're just confusing. Why not just put the two numbers and save everyone the trouble of having to google what WXSDHDGA (don't bother, I just made it up ... at least, I hope so) is supposed to be.
Back on topic.
OLED
Black is really, totally black. The contrast ratio is technically infinite, but that isn't just a good thing, as it hurts my eyes in the dark. It's a bit like staring at a television in a pitch black room.
Colors are more vivid (read: oversaturated). Most people love that but to me it just looks unnatural. Like kid's toys.
The pixels will degrade rather quickly and lose brightness in the process. Since each primary color ages at a different rate your color balance will shift. You should be good for 2-3 years, though.
As long as the image displayed is mostly black or dark, it'll use less power than LCD, on bright images a lot more. Setting your background to pitch-black is a real power-saver on these devices.
Most OLED displays currently on the market use something called a PenTile matrix (see http://arstechnica.com/gadgets/news...exus-ones-screen-science-color-and-hacks.ars/ or just google it), where each pixel only has 2 subpixels instead of 3. As a result pixels cannot independently display every color but need to work together with adjacent ones, which reduces the effective resolution of the display by at least 1/3. Photos and Videos still look fine, but text gets ragged colored edges and is a lot harder to read than on an LCD.
Handsets with OLED+PenTile matrix, f. ex.: Samsung Galaxy S, Nexus One
Handsets with OLED+full matrix, f. ex.: HTC Legend, Samsung Galaxy S2
LCD
You won't get black, only dark gray, because light emitted from the backlight can't be perfectly masked. As long as the display is on it will emit light.
Power usage is just dependent on the brightness setting, not on the content displayed.
AFAIK all current LCD displays have a full subpixel matrix
A lot of the rest, like color, viewing angles etc. depends on the panel type used. Usually that's TFT, which is kind of meh, the premium choice is IPS (iPhone 4 and some LG phones, like most (all?) 2x variants).
The choice between a (full matrix) OLED screen and an IPS LCD is a matter of personal choice, if you can't get either, get a TFT LCD. Personally I'd never buy anything with PenTile, but, well, some people like it so YMMV.
Going by my preferences and specs alone, the iPhone 4 currently has the best mobile display, followed by the LG Optimus Black / Speed (2x). Since I don't like iOS that would make the 2x the handset of choice, if I needed a new one right now. As it is, I'll wait for the SGS2 and see how that stacks up, first.

I'm brand new to the world of Smartphones, and hence don't have much perspective, but I DO have direct experience comparing the 2 types.
I started last week with a Samsung Galaxy S 4G with the SAMOLED(+?) screen. The screen on the Samsung was very, very nice. As others have said, the blacks are TRUE black and hence everything tends to "pop" more. Think of it kinda like a plasma vs an LCD HDTV. Plasma blacks just can't be beaten by an LCD.
I moved to the G2X two days ago, mostly because I decided I wanted as close to a stock Android experience as possible AND a more future-proof dual core phone. I have NO complaints about the screen on the G2X. Sure, the blacks aren't quite as black, but the colors look great, it's bright and readable, and I don't use a black background anyway. As an added bonus, it is MUCH easier to read in sunlight than the SAMOLED was on the Galaxy.

Just got mine today. Nice phone, but the screen.....
The top left and right corners of the screen have a small white glow, the same as some lcd tv's had in the beginning. So the "color" black isn't covering my whole screen....
This is NOT my phone, but just to show you where the glowing parts are.

Mate, isn't that the lg notification bar? I've heard about some people having backlight problems though, but than it is your phone

[Q] iPhone 4 vs Note Display (Do I have a bad Note?)

Hey Guys,
It has been two months since I switched from my iPhone 4 to the Galaxy Note and I haven't touched the iPhone since I bought the Note until yesterday to factory reset it and give it to a friend when I noticed that the iPhone's display looked better (higher resolution) than the galaxy note!! I felt that my Note has a bluish tone to its display?!?! Is this normal or do I have a faulty note? Please help!!

The iPhone 4 has a higher PPI (Pixels Per Inch), so the iPhone's screen is sharper. But the Note's screen is far from bad. Can you post a pic of your screen? (Not a screenshot) And try to get a good pic.

I am at work right now. Will post pics of the Note once I get back home (Can't post pics of iPhone and Note together cos I gave the iPhone away). I am not saying that the Note's display was bad but when I placed them side by side I could tell that the iPhone's display was better easily. I thought the Note should beat the iPhone in display easily because of the Note's higher resolution.

iPhone 4 (and 4s) has smaller screen, but higher resolution: 3.5 inches 960 × 640 px at 326 ppi. So it's screen shows more detail than the one on the Note.
I played with iPhone 4s and the Note side by side and would agree that movies, for example, often look "better" on the iPhone, especially the darker sciens. Although the overall picture is smaller, the iPhone's super LCD screen tends to give "more natural" look to a video than the super AMOLED screen on the Note, especially if the quality of the video encoding is not that great. In my experience anyway...
That being said, the quality of screens on the Note appears to vary quite a bit. There's a couple of rather long and active threads here discussing the screen issues...

Coming from a One X i must say that ever since I had the One x i simply despise amoled screens. The Black might be good but i'll take better whites over blacks any day. Apart from that the screen also felt so much brighter than the amoled screen.
The first thing I did when i heard of the nexus 4 and its price was to look whether the screen is Amoled or not. If it were an amoled screen i would have most probably thought twice before buying this device. Amoled IMO is just not there yet. I recall comparing the galaxy nexus's screen with my one x... That dim bluish white on websites was simply horrible.

Watch the first few seconds of this video (Nexus 4 boot up) and you will see that although blacks on the current top of the line LCD displays may not be the same as blacks on AMOLED screens, they're still VERY good.

Well, watched video. Amoled rules. Colors reproduction is way better. LCD way to go for improvement.

I have a question...okay the black is better on the galaxy nexus....but when you use your phone, the screen is always black ? because, the white is better on the nexus 4 and the contrast is a lot better. So i don't understand all of this thing about the black on the galaxy nexus....( i used a lot the galaxy s 2 )

This isn't English
How about you ****ing note that in the title, or at least somewhere in the post?

Like I've said before, what's the point of having on screen buttons when the background of the buttons are pure black? And until unless the phone doesn't produce deep blacks, what's the point? The Galaxy Nexus feel more like a Nexus MAINLY because of the AMOLED display.
Don't know why people keep complaining about the PenTile, it's not bad. It really isn't. The Galaxy Nexus, I agree, had some yellow-ing issues but most of the devices DID NOT. I had those issues - My screen broke - I got a new screen and it's FANTASTIC.
Just yesterday, I compared my Galaxy Nexus's screen with the HTC One X, the iPhone 5 and the HTC Sensation (All 3 having LCD displays) and trust me, none of the phones stand a chance in front of the color production of the Galaxy Nexus.
The main reason I didn't buy the Nexus 4 and I never will is the AMOLED. Nexus devices have had AMOLED since their first release. From the HTC One X to the Galaxy Nexus, the devices have been AMOLED and they looked amazing!
Sure the Nexus 4 has a great crisp screen but it surely doesn't beat the Galaxy Nexus in terms of color production and the black levels.
But well, every one has their own opinions. Don't jump on me!

No thanks, Jeff. Pentile is an absolute disaster. Forget color reproduction. It has nearly 30% less sub pixels than the Nexus 4. I still remember telling people that the screen is 720P. My iPhone carrying friends literally laughed, because the difference in sharpness between the two screens was a complete and utter joke. Blacks are only noticeably different in a dark environment (try to see the difference in daylight; you can't), and considering most of us use our phones mostly in well lit areas, I'd take LCD > OLED. Lastly, do I even need to mention how pathetic whites were on Samsung crap? What about the severe burn in? Yeah. No thanks. AMOLED, never again...

Contrast:
Amoled>>>LCD
Contrast is the brighness of the whites divided by the brighness of the blacks, since the blacks on Amoleds have almost zero brightness their contrast is extremely high.
How contast is not everything, my main use of the phone is browsing and messaging so I will take accurate whites over perfect blacks anytime.
I also got sick of the oversaturated colors an even worse the unavoidable screen burn that is even worse on phones with onscreen buttons.

so i think the nexus 4 is definitely a degrade from Gnexus.... every one saying that ips lcd has a far better brightness than amoleds but its clearly showing in video that TRUE IPS PLUS LCD is totally crap when comparing to HDAmoled ..color reproduction,contrast levels, blacks as well aswhites(look in when comparing chrome browsers) , saturation everything excellent on AMoled.... i thought nexus 4 has a super duper display....but its a big dealbreaker for me...i sold my s3 for a nexus4 ...

Actually you tend to find colour reproduction on AMOLED is worse. Sure it's more vibrant looking (often referred to as over-saturated), but that doesn't make it accurate.

Tab S2 9.7 vs S 10.5 screen quality

Hi
Can someone who have used both S2 9.7 vs S 10.5 and had some chance to compare them side by side comment on the screen quality? I'm interested because I have the S 10.5.
Aside from the obvious aspect ratio and minor size difference, how are the displays. Text sharpness, clarity, color saturation, contrast, etc.
I saw one amoled phone (don't remember the model) and what I liked about it was the display image seemed to float right at that surface of the screen. I think it's because the gap between the top glass and display is very thin. I don't get the same feel with the Tab S, i.e. it feels more like the display image is below the glass, if that makes sense. What about the S2?
I hear the S2 uses pentile attachment as opposed to RGB. I know this is controversial and some say it does not matter, but if it does not affect quality then why don't Samsung and everybody use it in everything from phones to high end TVs since it's cheaper and less power hungry.
Thanks

Question S8 screen quality?

Looking to buy S8 as it is comparatively more compact & cheaper.
How is the overall quality of LCD on S8? Does it have any accuracy issue like warm tone?
Thanks

S8 has got TFT panel instead of OLED like s8+ and S8 Ultra has got.

Screen quality is better than Tab s5e
(especially if your have allergy and tears on Amoled)
UPDATE: screen is amazing

Screen of S8 is good, it's a TFT screen but is consistent even in the edges of the screen. Only issue i got is that Samsung doesn't have adaptative warm tones on panels that aren't oled, also don't expect perfect blacks.

It's great. I have no complaints with it.

Great quality (Samsung galaxy tab s8 ultra ).

He is asking for s8 which hasn't oled. S8 ultra has oled. If you like oled, you don't buy s8 regardless how good is the screen, it isn't oled..

You are right Sosimple, i respond to quickly. Sorry for that.

I've a Tab S8 since some months. The screen quality is excellent. It is a LCD display , one of the best.
In the past I had also a Tab S7 plus with amoled but I like more the Tab S8 because of the size. The LCD allows also better energy consumption compared to the amoled.
I may suggest to buy also the keyboard with trackpad (the one made for tab S7 , not the recently released version without trackpad) . It is a nice accessory that transform the tablet into a semi Surface expecially in the Dex Mode.

LCD takes actually more power than amoled/oled. Since black on amoled/OLED has got leds turned off which takes less power on black areas. While LCD keeps leds on and mixes colours into more like grayish black.

What you say it's true but S8 battery life is much better than S8+ (according to what i saw on the internet), this might be cause S8 is the only one with adaptative refresh rate
