Screen: Picture quality Tab VS galaxy S?

I had a HTC Desire and bought a Galaxy S. I didn't notice a big different between the screen on those 2. Now I bought the Desire HD, and I'm VERY disappointed with the screen on this! Yesterday I ordered a Galaxy Tab, but I cancelled it now, as I'm VERY afraid that this screen is not as good as the one on the Galaxy S. Having used an AMOLED, I think everything else is a step-down...
Anybody used a Galaxy S for some time that uses the Pad? How is the screen quality? What about Androids coming soon with at least 4" Amoled?

Samsung manufacture something like 90%+ of all the AMOLED panels in the world and they've only just announced the first 7" on for use in mobile devices, so it'll be a while before we see anything Tab-sized with an AMOLED or sAMOLED display (current rumours say June 2011).

The screen on the tab is excellent. I doubt any of the alternatives currently running android have better screens, so its a pity you cancelled your order.

I have an HTC Desire and bought a Galaxy Tab over the weekend. The screen on the Tab is really good - it's very, very bright and very clear. Only difference is the blacks aren't quite as 'black' as the HTC.
Re-order, you won't regret it.

Ditto!
The screen on the Tab is very good, even when compared to the AMOLED Desire.

Is very very good

Two thumbs up. Don't know what the fuss is all about on AMOLED. The Tab is real beautiful.

I find the Tab's display more than adequate. The colors are vibrant (saturation can be adjusted) and the white/black levels can be configured too.
The IPS technology used in the latest Apple products offer better viewing angles (in terms of maintaining color and contrast), whereas the Tab's display tends to wash-out some details. That being said, it is still amongst the better displays, nothing deal-breaking. There's also a slight issue with regards to refresh rates, which creates a tiny bit of ghosting, particularly visible with text rendering. Once again, it's a really minor issue, just being picky here.
Overall, I absolutely love reading and playing on the device, the screen is simply beautiful. I haven't tried outdoors yet, but I guess it's like every single multitouch-display out there: it sucks !

I also have a Vibrant but so far the Tab's screen has very good so far. I've only had it for less than a day but I can say it's at least not strikingly apparent.

I have both Galaxy S and Tab.
Side by side, S has better screen. Black is really black because of the amoled technic and the overall contrast is better.
But Tab has also very good screen, it is excellent. If there wasn't the S to compare, I couldn't imagine any better.

Choose: 1024x68 IPS display or 1280x800 LCD display?

In comparing the iPad with the Xoom, no doubt the iPad's display looks nicer. I have Dell IPS and non-IPS monitors and the color gamut on the IPS looks nicer.
However, I don't think Motorola "cheaped" out on the display as I've been hearing in passing. I think what it came down to is this no parts manufacturer has developed a mobile IPS display at 1280x800 because if they did, you know Apple would've used it in their MacBook Pro's.
So, if you were VP of Moto's Product Development, would you have made the same decision?
UPDATE:
Here's a link to an image that you can use to test image quality across different device. Try to display at 100% as different scaling algorithms may degrade the image quality.

ips for sure. Love the xoom, but the display is not the best. Even my Viewsonic G tablet does a better job displaying photos when viewing straight on. Maybe someone will figure out a way to tweak the xoom display for better contrast and color.

For a device this small, I'll take the larger resolution, and quality wise, I'm perfectly happy with the Xoom display (particularly after turning off auto brightness).
Now if we're talking about a LCD for PC, I'll keep my IPS

The stock photo viewer does suck. If the image is scaled at all, it looks a bit garbled.
Go to the market and download QuickPic. It's a MUCH better photo gallery app, and even large images taken with my DSLR look good scaled down.

I'd have to agree. I'll take 1280x800 and slightly reduced image qualit over 1024x768

When I get my Xoom, I plan to do a cbr/cbz comparison against my R10 (1024x768 IPS screen).

IPS is still LCD. IPS is just one of the better types of LCD panel, and hence your thread title is weird.
Why are some people saying that the LCD on Xoom is non-IPS? Has it been confirmed already? I can't find the model number of the Xoom LCD panel. iFixit doesn't list it, maybe I can email them and ask. But from all the review pictures and videos I've seen so far, the view angel of the Xoom LCD does seem very wide, on par with typical IPS panel. Color reproduction-wise, it can vary a lot among IPS panels depending on model. Without doubt, the one on the iPad is exceptional. But then, with the volume that Apple is shipping, they probably won't have much problem getting some custom made specification.
EDIT: Ok, I just Googled. iSuppli has the part list
http://www.isuppli.com/Teardowns/News/Pages/XOOMBOM-Totals-$359-92-IHS-iSuppli-Teardown-Reveals.aspx
The display model is AUOptronics B101EW04 V.0, and it doesn't mention the panel type (no, TFT is not a panel type). Googling this model number gives me nothing. iSuppli does mention that the IPS panel on the iPad is infact AFFS panel, a high quatlity and newer type of IPS panel (those who have modded their Thinkpad X200 are familiar with this type of panel).

Alright, answering my own question.
Did some Googling and it seems that AUO doesn't make any IPS panel. Cannot find B101EW04 on their website, but their website does list a B101EW05. Judging from the model number it may be similar to the B101EW04 that Xoom uses. Perhaps it's a newer model that replaces the B101EW04?
http://www.auo.com/?sn=149&lang=en-US&c=34&n=146
B101EW05 is a 10.1" 1280x800 VA panel. VA panels are high quality panels that are comparable to IPS. Dell WFP 2407, 2407-HC, and 2408 (and maybe more, I just know these models) all use VA panels and everyone knows that they look exceptional. The B101EW05 looks spectacular on spec sheet, and enters into production only in Q4 2010. Perhaps just a little bit too late to be employed on the Xoom?

Someone in another thread that is a professional photographers said the xoom is more accurate on color than his ipad, for what it's worth.

Are you also keeping yours now??

Don't confuse a bright and colorful display with accuracy. Accurate means the way it looks in real life. Look out the window, it does not look like Wonderland or Oz.
A photographer needs an accurate representation on a device of his work so that the final product is not misrepresented.

Well, yea, I think most XDA readers know that IPS is LCD, but I just wanted to keep the title short.
I just added a link to a test image for those who want to test the quality of their different displays.

I was doing a side by side comparison against a friends iPad and my Xoom when playing a movie. They both look really good, but the main difference is the iPad being 4:3 looks really awkward when playing widescreen movies. The good thing about a "fragmented" OS is apps had to detect the screen size to work correctly, and now we have all these widescreen tablets of whatever resolution people like, while iOS is locked into 4:3 forever basically, or risk huge backwards compatibility problems as I'm sure 95% of iPad apps have 1024x768 hard coded in them.

Resolution wouldn't be a problem for Apple. Since iOS devices are made only by Apple, Apple has complete control over what resolution their devices use. And given the volume that Apple ships (they sold 15 million of iPads in the first 9 month for god sake...), they probably can have a screen made to their specification (e.g. the super high pixel density screen of the iPhone 4).

It's the viewing angles that make IPS screens so much better.
Lay both an iPad and a Xoom flat side by side in portrait mode and look at them as you're laying down on a bed. You'll definitely notice a difference. The blues at the top of the Xoom screen of the tron-like Honeycomb wallpaper turn purple. The iPad colors largely look the same no matter what angle you're looking at it.

As a photographer, although i love android os but i still have to go with Ipad screen, the color look more accurate to me.
i went to Bestbuy and try out the xoom, the screen is pretty bad but better than my g-tablet.
I really hope that people can port honeycomb to ipad 2.

I tested both as well at Best Buy. I wouldn't say that it's "really bad." It's not as good as IPS, but it's not bad by any means.
Before I got my Dell Ultrasharp U2410 monitors, I was using plain Dell LCD monitors. I now have a quad monitor setup, 2 normal Dells + 2 IPS Dells. The U2410's have the edge on color gamut, but other than that, quality is very close.
If Samsung was smart, they'd make a 1280x800 SAMOLED display and keep it to themselves or else charge a huge profit margin to their competitors.
Sometimes, I wonder how these product VP's get their jobs? It just seems like all their decisions are against common sense.

Unfortunately Super AMOLED isn't available this big yet. The Galaxy Tab 7" has a pretty nice screen, and early hands on preview of the Galaxy Tab 10.1" say that the screen on it is just as nice. It's not surprising though, since Samsung is probably using their own panels and their panels are always nice. If you look take a look here:
http://www.samsung.com/global/business/lcdpanel/product/note.html
Samsung makes 3 sizes of tablet screens, 7", 10.1", and 9.7", which coincides with the almost confirmed rumor that they will reveal another 9.7" Honeycomb tablet at CTIA. If you want a 10.1" Honeycomb tablet with nice screen, wait for the Samsung 10.1" or 9.7" Galaxy Tab. (But the Galaxy Tab 10.1" has no USB port and SD card slot .... yes, Samsung somehow think it's a good idea to use a proprietary 30-pin connector)

our IT nerd from work lent me his iPad for direct comparison and I have to admit that the Xoom does not even get close to the viewing angles of the iPad. Due to the 16:10 form factor the Xoom also appears smaller. Still, I'm having so much fun with my Xoom that if you don't torture yourself with putting the iPad right next to it it works well!

Screen Angles

Xoom versus a GTAB versus a SmartQ R10 (same IPS screen as an iPad):
http://www.slatedroid.com/index.php?/topic/15865-screen-angles/
Bottom line - it's better than a GTAB, but not as good as the IPS screen. The only pro for using it for comics is that the 16:10 screen ratio is almost perfect for a comic - very little of the screen is wasted.

I had a Gtab, God the viewing angles were terrible! I mean just awful.
No hardcopy to compare colors?

I returned my GTAB because of the viewing angles and the occasional touch failing to register.
The XOOM viewing angles are impressive. When I was shoing a friend how to use it at breakfast the other day.. I was able to look at it from my side of the table upside down and see it well enough to instruct him how to use it as well as press the right things. That is an impressive feat for any LCD in my opinion.
EDIT: Why is the XOOM out of focus in every single picture?

Same as you all on the gtab. It was so cheap but man the angles were so bad. I bought it at 8:30am and as soon as I got out of work I returned it.
I realllllyyy wanted to like it but man Viewsonic blew it. My Xoom isn't as good as my iPad but is more then passible.

I might have to do that, later - Sgt Rock just happened to be what was available at that particular moment. The IPS screen might actually be a little softer than the Xoom, but I prefer that. I can actually see the yellowing pages on some of the scans, on the IPS screen.
The Xoom definitely is passable, though. If I didn't have my R10, I don't think I'd even notice a problem at all.

Traded in my TF for a....

Hey Folks,
First and foremost, I'm not hear to start bickering with anybody...just here to share. Yesterday, I received my TF from BB via UPS. I was anxious to get it but at the same time had fingers crossed being that there's been quite a few documented issues both hardware and software related. As I turned on the device, the first thing that was blaring at me was there was screen separation. This was under the bezel where I could see the white of the black light clearly. Not the same as light bleed (there was some of that also). I went ahead and setup my account but had already known at that point that I was going to at least replace the unit. Initially, the unit was on 3.0.1, but after the battery had charged to about 70%, I got the notification that the 3.1 update was available. Now prior to me updating, which in all honesty wasn't a ton of time, I was experiencing FC's left and right. Believe me, I'm not the drama queen type, BUT IT WAS FREQUENT. Next thing I noticed was that, albiet not to thick, the tablet was quite heavy..a fair share of fatigue after holding for a short spell. In the TF's defense, I know a Xoom would have been equally taxing, as would an Iconia, etc.
Now I had been in Best Buy the same day that my TF came in the mail and saw that the Tab 10.1 was being released the next day (today). BTW...I live in NYC and was at the Union Square location. Fast forward to today; I was contemplating what I was going to do. Should I replace the unit with another and take the chance that everything is okay or do I choose something else. Low and behold, greatly due to the fact that there have been so many reports over various forums, I chose the Tab 10.1.
I've just had it a couple hours now, but so far here's what's evident. It is quite a bit lighter and more comfortable in hand.There's just about 0 light bleed. The colors are brighter on the Tab (take that as a pro or con....the colors are 'Galaxy S' oversaturated). There have been 0 FC's and the Tab is noticeably more responsive even when compared to the TF after it updated to 3.1. I'll miss the TF's widgets and extra cloud/DNLA services even though I never got a chance to hook it up. It's good to know that there are already accessories available that are made just for the tab. I bought a book style case for it from Belkin. '
All-in-all, I felt a bit let down enough by the TF to quickly decide that it wasn't the right choice for me. If any of you are feeling the same, I pray that provided you don't have any major hardware issues that Asus and Google can straighten them out with future updates. As for me, I prefer to take a less tentative unsure route.

Interesting. Thanks for the input.
Is there a keyboard case for the tab?

no microsd? dealbreaker.
samsung qual control? dealbreaker.
active # of developers for tab? semi dealbreaker.
love the TF. love the dev community. love the dock. good luck with the tab.

Keyboard Case? Not sure. I saw the Keyboard today, but don't know about the case to be honest.

Call it the luck of the draw and I hope I continue to be lucky, but as I'm using I haven't encountered anything as yet. But again, this is just after a couple hours of use. I will tell you this much though, there are certain options that I can't seem to find on the Tab...such as the option to have the Tab be seen as a desktop device so less mobile pages load. As far as the microsd, it's not that big of dealbreaker for me as I don't necessarily need to have a ton of movies or music on the device. I'll be able to hold a decent share, but it was never one of my major objectives to load the baby up like I would an ipod or my mac. I may change my tune. I guess time will tell.

This is where your rant fell apart for me.
The reason the colours are so saturated on the Galaxy S phones is because of the SuperAMOLED screen they have in them.
The Galaxy Tab 10.1 uses a traditional TFT panel which is absolutely nothing special whatsoever, TFT is the most basic screen technology you can get right now.
You are imagining things, dust and light bleed issues aside the IPS panel in the Transformer is far, far superior to the ancient TFT panel in the Galaxy Tab 10.1.

The Galaxy Tab 10.1 has a PLS panel which is suppose to be an incremental improvement over IPS with even better viewing angles and brightness.

What are you talking about??? The 10.1 US verison runs on a PLS screen which is a IPS panel....Maybe you're thinking about the 10.1V which was release eariler this yr.

I guess it may have been the non-US version.

The tab has a pls display (better than ips) not tft. And the saturation has nothing to do with being an amoled or not. Samsung just likes to increase the saturation on its displays so they look more appealing

That is just a very generic description for 1280x800 LCD. Even IPS panels are WXGA TFT. That isn't suppose to tell you what kind of panel it is, be it TN, VA, IPS, or PLS.
So the description is correct, it's just vague in not including the panel type.

Learn to read, this fact was already pointed out by at least two other people. Jesus, do people just enjoy kicking someone while they are down?
Also, I'm still not entirely sure. I'm looking at some sites and I see a lot of them listing a WXGA TFT display.
Edit: Okay, I guess this link confirms it. I still don't care though, I just went through two months of Transformer back-order bullcrap and I'm guessing it will be the same story with the Galaxy Tab for a while.

Yeah, but when they just say TFT it usually means the crappiest kind. If they had something to advertise they would (well looks like they do, not sure why they don't advertise the SuperPLS panel more).

I'm still undecided what to do with my Transformer. This is the second one I've had. Sounds like my first had the same issue the OP has with his and my second has a light colored blotch in the middle of the screen.
Both tablets have some very positive qualities. So hard to weight what is going to be more important to me.
Transformer
+ $100 cheaper
+ micro SD
+ mini HDMI
+ netbook style keydock
Galaxy Tab 10.1
+ lighter and rounded edges (more comfortable)
+ better speakers
+ PLS display
+ LED flash
+ just better looking
Almost afraid to say it, because I detest custom UI, but I almost want to give the Galaxy Tab 10.1 a + for TouchWiz UX. The demo of it actually has some very nice looking features.
Because of the lack of micro SD I almost certainly will need to spend $200 more for a 32GB Galaxy Tab 10.1, versus the 16GB Transformer I'm using now with my 16GB micro SD card. So the price difference is greater (I am sure I need more than 16GB for a tablet).

Sorry, my experience has been that people like to gang up. Someone makes a clerical error and makes a misinformed statement, one person points out this error and it should end there. But usually you get a dozen other people join in and say the same thing just to feel good.
So yeah, sorry that I misunderstood your intent.

Same here. My TF is on its way to Asus for Repair. My display went dead after 1 months.... Before, having an sd slot was very important to me, but now its not cause I pretty much stream all my videos from my server at home with plex. What I like about the 10.1 is the battery life (engadget review) got 10 hrs, and better speakers. I am going to purchase 10.1 next week from Bestbuy and test it out. IF its good, then my TF will go straight to Ebay.
Here is an mini comparison of both Tablet.

Im typing in the browser now and there is a bit of lag, but one thing that makes it a bit easier is that the Tab has haptic feedback. The TF didnt or by default it was turned off. The lag is definitely there though.

You are imagining things, dust and light bleed issues aside the IPS panel in the Transformer is far, far superior to the ancient TFT panel in the Galaxy Tab 10.1.

Again, I'm not here to bicker or say mine is bettrr than yours, I'm just sharing. However, at the same time I'm not imagining things. The colors are very bright. Similar to what i have seen on Galaxy S phones. Moreover, that's not necessarily a pro. I am more partial to colors being closer to neutral.

Screen Comparisons: Contrast Ratio

I've been trying to understand the relative differences between the IPS displays used in the IPAD 2 and the Transformer, the Super PLS display of the Galaxy Tab 10.1 and the TFT used in the XOOM. I settled on contrast ratio as an objective means of comparison.
Article 1 XOOM: 750
Article 2 XOOM: 597!
iPad 2: 775
Galaxy Tab 10.1: 830
Transformer: 763
Article Quote: "Contrast ratio is also better on the Galaxy Tab 10.1: 830:1 vs 763:1 on the Eee Pad Transformer."
What surprises me the most out of all this, besides the XOOM discrepancies , is that the contrast of the Galaxy Tab 10.1 display is not as incredible as we were lead to believe. It compares favorably with IPS, but isn't really leaps and bounds better. In fact, it might have equivalent or slightly lower contrast than an IPS display, or conventional display but better viewing angles.
Interesting quote: "On the other hand IPS (and PLS) has significantly lower contrast ratios compared to the best VA based panels that Samsung and other manufacturers have used in high-end phones for years."
Side note is that the multiple contrast ratios for the XOOM screen might reflect the multiple screen sources/manufacturers that were used in different XOOMs.

The most important things to me on a tablet screen:
1. Color reproduction. Is it uniform and even? This leads me to
2. Viewing angles, top, bottom, left and right. Does the screen stay relatively sharp or does the image dissolve/wash out?
3. No back-light bleed. This is inexcusable regardless of the lectures people spout out about it being inherent to the technology. It's not when the product is designed correctly.
The panel in the GTab 10.1 is beautiful. It meets my criteria where the xoom failed on all of them and the iPad failed miserably on back-light bleed.
Contrast ratio to me is just a number. I have tolerances for all my electronics devices and to me, the panel on the Samsung is the clear winner in the tablet race. Let's hope the build quality follows suit. I'm already starting to get annoyed at how long a full charge takes.

The screen looks amazing! The only thing I noticed is that the screen calibration is a
little bit oversaturated. I'm planning on using mine as a photography/design portfolio and have noticed color shift when compared to my calibrated monitor.

I had Xooms (with both screen versions Auo and Sharp), an I pad and now a Galaxy Tab 10.1 and the screen on my tab is far and awy better than all of them.
The Xoom has 2 screen fkavors, Sharp and Auo optronics. the screen mfg by Sharp had much better color saturation and better contrast, but unfortunately for me, a ton of light bleed due to a defect in the panel.
Specs only tell part of the story.

When Samsung releases the kernel source, supercurio can start developing his Voodoo Sound and Screen tweaks for the SGT 10.1, which will make color reproduction much more realistic.

I'm new with android and this is awesome to hear. I also own the iPad 2 and Datacolor made an in app color calibrated picture viewer called SpyderGallery but an overall screen color calibration would be awesome!

I threw these numbers out there because, so far, almost all the info on PLS panels used in the Galaxy Tab 10.1 has been primarily subjective. Its totally new technology.
However, recently, Samsung has started to develop the PLS Panels for use in stand-alone computer monitors, and some reviewers are beginning to analyze and reveiw the technology. This is a really interesting article, and "sheds some light" (to make a bad pun) on the PLS panel technology used in the Galaxy Tab 10.1, how it works and some of its pros and cons:
http://www.xbitlabs.com/articles/monitors/display/samsung-sa850.html
Remember this is a stand alone PLS monitor, so one would expect its performance would exceed that of an integrated tablet screen, but they found a contrast ration of only 545:1. Thats pretty bad in my opinion. They try to theorize why this occurs:
"The low contrast ratio may be due to the poor uniformity of the backlight. The picture based on the results of my measurements shows a bright spot in the center of the screen, just where I measured the contrast ratio. That spot is not as bright as the bottom left corner, though.
Although the extent of the variation in brightness is exaggerated in the picture for illustrative purposes, the monitor is obviously far from ideal, especially with black. Talking about the exact numbers, the average nonuniformity of brightness for black is 8% whereas the maximum deflection from the base level is as high as 45%! For white, the average and maximum are 3.6% and 8.3%, respectively. It’s hard to say why the monitor is so good with white and so poor with black....."
So, disturbingly, they found the first dedicated PLS prototype monitor to have POOR contrast ratio!! Not what you would expect. They theorize that it might be due to poor backlighting, but it is worrisome.
To summarize what the reviewers found after examining this prototype PLS monitor:
Highs:
•Low response time, good color rendering, excellent viewing angles
•Full coverage of the sRGB color space
Lows
•Low contrast ratio
•Poor uniformity of backlight for black
If this review is accurate, these first panels seem to show that the PLS technology is good, but not great. Its an OK alternative to IPS but really not that stellar in its performance. Its biggest advantage seems to be that it is a cheap alternatative to IPS that has much better viewing angles.
Remember, one of the biggest selling points cited by Samsung was cost! Its cheaper to produce than IPS. That may be a larger motivation to Samsung than increased performance.
Of course, how this translates to the performance of our own toys is debateable, but its something to think about beyond the subjective impressions we have already heard.

That's definitely interesting. Perhaps the larger the panel, the greater the difficulty in achieving a uniform amount of back-light. I have definitely experienced this with clouding and flash-lighting on TV sets (and mainly the reason I switched to plasma - I'd rather roll the dice with image retention than sit and stare at uneven back-lighting during movies)
Have you read about the issues Samsung's having with the panel thickness on the GTab 8.9? There's not much other than a translated-from-Korean report, but it seems the company (and panel suppliers) use a very thin "G1F" touch panel for the 10.1, and may be forced to use a (40%!) thicker application (GFF) for the GTab 8.9 due to either shortages in supply or complications in the manufacturing process.
^I think that bit is a key factor when comparing display performance - anything that sits on top of the actual pixels will contribute to the clarity of the content being displayed.

Thanks. Very interesting article. Especially considering that there has been a lot of talk about the quality control of the existing 10.1 panels. There have been threads about moisture under the screen, dust under the screen, lots of people with dead pixels. Haven't encountered nearly so many screen anomalies in other device forums. Wonder if that's the reason the GTAB 10.1 is so scarce in many places. Perhaps there are problems producing the 10.1 screens.
Oh and I went Plasma for all my TV's as well for the same reason, in addition to the faster response time. Even my video gaming TV is a Plasma. And I have never had a single problem with image retention.
Edit: Looks like another website has an article about the screen supply problem, only this time relating specifically to the GTAB 10.1. They speculate on a change in GTAB thickness if they can't make enough of the screens.
http://www.slashgear.com/samsung-galaxy-tab-10-1-to-be-thicker-than-ipad-2-due-to-supply-shortage-10158766/
Maybe soon there will be THREE versions of the GTAB 10.1: The 10.1, the 10.1v and the 10.1 series 2 extra thick!

I just found dust on my screen. Its definitely behind the glass panel.
Samsung Galaxy Tab 10.1

Slashgear is rife with editorial errors. that article misquotes the one I linked earlier. They even have published content that indicates it's the 8.9 and not the 10.1 affected but the different panel thickness:
http://www.slashgear.com/galaxy-tab...tter-screen-in-some-areas-at-launch-10158611/
Either way, I doubt the US will see the thicker screen - they continued shipping AMOLED phone displays here despite a worldwide shortage, causing many other markets to receive Super LCD screens instead.
