[Q] Would it be possible to replace the EVO Screen?

Would it be possible to replace the EVO Screen with a super AMOLED or a regular OLED screen? if so how? I just thought the EVO would look so much better with a better screen.

Amoled is overrated, i like my Evo screen just fine

How so?.....

burn in + power consumption on white screens aka websites, aka movies that aren't dark.

He didn't ask if people think it's a good idea or not, he asked if it's possible.
And to answer his question.. I don't know

Probably should be possible since HTC is changing to S-LCD since production of S-AMOLED has shifted to Samsung's phones until 2011.
If so then it should be possible.
What I do not like about the AMOLED is the PenTile Matrix and that itself will steer me away from it. I picked up the new Fascinate from Samsung and the Pentile dots drives me crazy. On smaller text its just too noticeable and very fuzzy on Google Maps when zooming in.

Pentile looks rediculously disgusting.
S-LCD is the way to go, and i hope one comes out for the evo soon from china soon.
The lcd on the evo is a very high quality LCD as is. I don't know why you would be thinking it would look better with a better screen in the first place.

True HD IPS is much sharper than HD Super AMOLED

I know the True HD IPS screen is better than the AMOLED but I didn't think it was that much sharper than the HD Super AMOLED on a borrowed Galaxy Nexus. It's almost like putting on glasses, very crisp detail. I'm guessing when there is a non pentile HD AMOLED the differences may be a lot smaller but against the pentile HD AMOLED the difference is huge. The only thing holding the Optimus LTE back against truly surpassing the Galaxy Nexus in just about every way is the lack of an official ICS rom but then there is always CM9 for those of us who know how to get it on the phone.
Could take some pictures for comparison if anyone is interested

Yup. 3 subpixel elements rendering out light using RGB + a decently wide gamut backlight, rather than educated guesswork (well, subpixel rendering) using only a combination of two subpixels per pixel (and still off color). Also, no uneven black screens. Minor nitpick, but has always annoyed me on all amoled displays (it really shows up a night).

Also keep in mind that the G nexus has a slightly larger screen, therefore lower PPI.

There's no question about it. I also compared the Nexus vs. Nitro side by side, and the text on Nexus' screen is more like my old 3GS, but on Nitro it's much sharper. Oh, did I mention the over-saturated color?

What's funny to me is that the next great android super phone, the Galaxy S3 is STILL going to use a pentile AMOLED screen.

HTC did the right thing using the SUPERLCD in the one X imo

Yeah that is disappointing. Those who say pentile isn't noticeable never used a high density IPS display; I could see what looks like a dithering pattern everywhere coming from the optimus true hd lte. I also don't like how AMOLED has these blotches everywhere when viewing the screen on low brightness.

I refuse to get anything less than our True HD IPS. Coming from an iPhone 4 to the Nitro, me eyes have been looking at retina quality screens for too long to go back to anything less.

That's the difference I'm talking about

Another thing to point out (and maybe it's just me) the last phone I had was an infuse 4g and I noticed a burn in with the status bar, my brother's phone is the same which is a galaxy s. Both of them are amoled. Which I could notice while playing games on them.

True I've already seen a few AMOLED displays with burn-in visible. I think LCD technology is also prone to some image persistence problems but not nearly as prone as AMOLED

Wow the youtube video really gets the point across. And I was already considering buying a Galaxy S3. I think we may be spoiled by our phones because there is a possibility LG may not continue to do the IPS displays. Also, the processor is a factor as well. I'm still on the fence between a 4X and GS3.

I've yet to experience the burn issues with OLED but I've never peaked out the brigtness settings for a prolonged period either which it strongly states can cause screen burn.. There is a divided group I've come to notice were some don't really get all that excited by the vibrant colors and outright detest the lack of viewabilty in open sunlight. I don't make any qualms against those and their reasons are valid. There are a lot of us however who are passionate about them for their stunning colors that captivate a photographers eye. I suppose it's an each their own issue but for anyone who is new with AMOLED, any prolonged brightness at the maxed settings on a fixed screen inevitably causes burn. I've personally never had any issues.

Biggest downside for me on p930 is the touch sensitivity. It's definitely noticeable compared to the skyrocket. It's especially pronounced on the screen edges. Otherwise, the form factor is better (thinner, textured back), the screen has a great feature where the glass curves over the edges of the bezel. Could be the reason the edges are less sensitive? I also prefer the three capacitive buttons vs. four. And as mentioned display quality is great: ppi, benefits of it's lcd vs amoled, etc. Show someone the videos included with the stock gingerbread wrong. It amazing.
Samsung said they are including the pentile again, because it lasts longer then the HD amoled display. Something else to consider.

This sorta seems like a slap in the face to current Galaxy S2 owners doesn't it? "Hi, this is Samsung, your Galaxy S2 screen should be dying soon, perfect time to buy a new S3!"

Basically, it's Samsung admitting burn in IS an issue, even within the 2 year confines of many phone contracts (though some in Canada get 3 years!?).

In Canada you basically have to go 3 year contract or the subsidy isn't worth it and you might as well buy the phone outright

I think it's more likely that they can't make a profit if they included Super Amoled Hd + displays.

Thank you for your new reel

I returned my Galaxy nexus and bought a LG Nitro HD. The screen on the Nexus had way too many flaws to pass for a high end phone. The yellow tint, and the ghosting were unacceptable to me.

Samsung & PenTile Displays

So I see lots of threads/posts about PenTile. Found this to be interesting, sharing it. It's mainly in regards to Samsung Galaxy S3 but as we know, Galaxy Nexus uses PenTile as well. So it would apply for our phones as well.
Samsung's Philip Berne explained to me that the blue subpixels on AMOLED displays actually degrade the fastest - quicker than the red or green subpixels. With a PenTile layout, the subpixels are arranged RGBG (red, green, blue, green), so they feature more green subpixels and fewer red or blue subpixels than an RGB stripe layout with the same resolution. Because of this, AMOLED displays that have the PenTile layout tend to have a longer lifespan than those with RGB layouts. Since Samsung is selling its phones to users that usually keep them for 18 months or longer, it has to be sure that the display will still offer peak performance at that time. According to the company, PenTile AMOLED displays have proven to be more reliable than those with RGB layouts.

Thanks. Saw a few links to this. I don't really see what the issue is with PenTile. In normal use, its next to impossibile to see.
I think what people have bigger issues with are banding/discoloring/streaking, not necessarily the PenTile arrangement. Its just a nice 1-word "catch all" for not liking a display.

Motorola gave PenTile a bad name using rbgw arrangements. Now everyone assumes they will get screendoor effects.

The RAZR coming out ~same time as the Nexus with that god-awful display definitely gave a negative connotation to "PenTile".

Pentile was somewhat noticeable on the first SAMOLED display that they had in the SGS lineup, but only when it was text on a solid background. With SAMOLED HD, the pixel density is so high that I have yet to be able to see a jagged edge on text anywhere. I wonder what people would think if Apple used a Pentile matrix on an iProduct. Probably be the best thing in display technology rather than the most hated if it happened.

I love my galaxy nexus and my friend got a htc one x and it does look really good but I prefer my nexus maybe cause I like dark colors

Yeah I agree with Motorola giving PenTile a bad name. When I first saw the Galaxy Nexus screen, I didn't even notice any differences. I don't know the technical terms on why it's different but compared to my previous phones, Nexus S / Galaxy S1 (Vibrant).. I don't really see any difference, in fact the GN looks even better but that might just be Super AMOLED HD. But whatever it is, it looks amazing.
The people criticizing about PenTile without even looking at the phone or trying it for a week or two need to re-evaluate themselves.

Ya, but Samsung still has not found a good enough manufacturing process to make regular "Super AMOLED+ HD" Screens at 4.6inch+ (hence the pen tile). That's why the screen's pen tile.

Y'know, I always thought that PenTile would bother me too much to ever use a phone. I'd seen some devices that used older or low-end versions of it, and they looked terrible.
I was apprehensive at best of getting the Galaxy Nexus. PenTile and the lack of an SD card slot bothered me, to say the least. Over time, I've grown to love the phone. Much of that is because while there are some issues with the PenTile display, such as some banding and purplish greys at very low or lowest brightness settings, these issues aren't noticed even at a slightly raised brightness settings. Otherwise, the display is one of the best performing displays I've ever had the pleasure of using. The colors are bright and vibrant, the blacks are black, there are no light bleeds common with backlit displays and the outdoor performance, while not the best, is still excellent.
Super AMOLED HD isn't perfect, but it's certainly a good step forward in the evolution of display technology.

Didn't you know? Apple never makes mistakes
When I was looking at new phones, Pentile bugged the hell out of me every time I saw it. I swore I'd never buy a phone that used it. After Google started selling the Galaxy Nexus, I took a look at the VZW model just for kicks, and I honestly couldn't tell the difference unless I held it point-blank.

Owning both devices, I actually prefer the one X screen over the nexus. Not by
a drastic margin though. Pentile displays are pretty atrocious on smaller resolution
screens (qhD or below).
It's a non-issue on the nexus.

I can tell occasionally but the high Res far outweighs the small nuance of seeing it in certain situations and being HD it still looks great. :thumbup::thumbup: for HD rgbg pen tile.
...of the people, by the people, for the people...

I thought the issues of the blue sub-pixels degrading faster than the red and green ones had been, basically, sorted - at least in as much that the degradation, whilst still faster than the other sub-pixels, was now slow enough that it was not particularly perceptible over the lifespan of the device (at least for the likes of phones, which are replaced much quicker than most consumer electronics devices).
I mean, according to Wikipedia the typical time for blue sub-pixels to degrade to half their original brightness is 14,000 hours - or 8 hours a day for 5 years.
Now I don't know about the rest of you but I don't have my handset's screen on for anywhere near 8 hours a day nor do I expect to still be using it in 5 years time.
And on top of that, it talks about 'experimental' blue OLED panels which can sustain 400 cd/m2 for over 62,000 hours - and that was in 2007.

Wrong. Galaxy tab 7.7 . If Samsung put samoled HD plus in sgs3 the price for the phone would be too damn high and the difference between screens quality is not that big as people who haven't even used it or used sgs1 with small resolution are trying to tell.

The Galaxy Tab 7.7 is using a SAMOLED+ screen that is ~7". It is not a SAMOLED HD screen despite having an HD resolution. At least they do not advertise it as SAMOLED HD, it is listed as an HD resolution SAMOLED+ display.

When the g nex first came out all I say was the horrible screen. So I bought the t mo gs2 which had the ugliest screen resolution ever so I got a nexus. The screen on the phone is awesome dark blacks deep colors this is a great screen. The super LCD 2 is nice but I prefer this

Bingo. I think Samsung is just trying to get the most value out of their current process-level.
The panel in my (oft mentioned) ET4G SGS2 is roughly the same exact dimensions as the GNex screen....though if you multiply 800x640x12 (subpixels) you come up with the same exact number you would if you multiplied 1280x720x5 .....and that 5 is where the damning "Pentile" moniker comes from.
So, that means these two (oft compared) panels have the same amount of subpixels arranged in the same amount of space in a slightly (or vastly, depending on how you looked at it) configuration.
So, for solid colors--aside from calibration differences and luminance (brightness) differences--the panels are effectively identical. I know I simplified a lot of the dynamics away with those qualifications, but, in this scenario we have the same amount of subpixels in the same exact density making the same exact color...
Before I decided to swap up to the GNex I marched down to the Sprint store and did the nerdiest side-by-side comparison I could and there wasn't a single moment where I had any question which screen I'd rather be looking at all the time....It's the GNex. The only thing I noticed was that it wasn't as cornea scarringly bright....big deal....after 30 seconds of screen-on maxed out the SGS2 screen turns itself down to prevent damage or something.....and then it's dimmer than the GNex anyway.

Apple is anal. They do alot more testing than Samsung because people will actually use + buy there phones well past its 18 month life span.

[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.

Amoled vs lcd

I love my amoled display, but which do you prefer, and why? For Amoled I mean [Amoled, Super Amoled, Super Amoled Plus, Super Amoled HD, (Super Amoled HD Plus?)] And for LCD I mean every other LCD you can name, there are too many for me.

After spending time on the beautiful display of the Galaxy S3 as well as many other phones I've worked on, I have to say the AMOLED will always win for me. I am REALLY big about contrast. I love being able to see a display with nearly infinite black level, beautiful saturated colors and decent energy consumption on top of that. OLED technology is the future in my opinion. It's a new technology and there's still so much room to make it even better and there is so much focus going into making it better.

There is no other screen technology that can produce black levels like amoled. However, IPS displays have the best viewing angles.

I've held my friend's HTC One X+ (a "Super LCD 2" screen) side by side with my S3, both at maximize brightness, outdoors on a sunny day. The LCD screen was noticeably brighter and easier to read in direct sunlight.

Yeah the whites are off, yeah the brightness isn't the greatest, yeah it is pentile. Technically it's not as good as the screen on the Nexus 4. And yet, my eyes prefer this AMOLED hands down. You can't explain that.

I have a Nexus 10 tablet and the GS3. Although the resolution of the Nexus 10's PLS (a type of LCD) display is unquestionably higher, the GS3's SAMOLED HD is still considerably better, in my opinion. With that being said, the IPS display used in the Kindle Fire HD is absolutely gorgeous. I'd go as far as saying that it gives the SAMOLED HD a run for its money.

This sg3 is my first Samoled device. I love it. Blows away my old Atrix display.
Sg3 is still oentile.but the new note 2 uses the newer tech with samoled..

I'm also coming from an atrix. Amoled technology is much better no question. Much more expensive to manufacture. I love how you put the brightness up a little and see perfectly in sunlight. Plus black themes will save you battery. Plus it looks amazing.

My cousin got the note 2 the other day, and we compared the two side by side. Honestly, neither of us could tell the difference.

The s3 has a great screen, but personally I do like samsungs super amoled + better. For example my s2 had a richer contrast to it, that I liked better. However, its still not something easy to see unless you're looking for it. The note 2 when i held them side by side, maybe had a little more sharpness, but that didnt matter to me at all with the fact I found it impractical to use with one hand. Or how I would hate having to hold that huge thing to my ear every time I made a call.

My wife has an iPhone 5 and i had the iPhone 4 (both LCD) and so I can easily make a direct comparison. The iPhone 5 is much brighter and is more accurate in its color. The Galaxy 3 has deeper blacks and more color saturation. Here is a professional comparison:
