screen with back light on and off. Indoors and out. This is a first generation Qi on a Lenovo laptop.
note: These are poor phone camera images. The first two are inside with normal lamp light. The second two are full sun (notice the sharp shadows) at my back with a slight angle to get rid of the glare. 1st generation Qi is not matte like Adam. The blue tint is probably from a white balance problem. The true whites on the screen are paper white and the blacks are black with definition. The screen was tuned with Adobe Gamma.
From questions on another forum I will answer some
of them here for you.
The Pixel Qi in LCD back light on mode functions like any other LCD. My color, saturation and sharpness is just like any other LCD at the same size and resolution. In back lite off it functions the same as the LCD with back light on except less color down to gray scale.
You are not getting a sub-par LCD. You are getting a normal LCD with enhanced modes. It is a positive. No negatives. You have not lost anything to gain the other. I can read my screen with a 4 graph array in my office with the back light off from 6' away. I can read for hours in full Florida sunlight with no more eye strain than you would have from reading any other 10" screen. The refresh rate is instantaneous just like any LCD.
thanks for the photos! i didnt know they already had a PQ in a notebook already. from all the images, i'm hoping Adam will look the same. what's the highest resolution the notebook is using btw?

Bought the Lenovo off Fleabay for couple hundred used. There are only a few laptops it will fit on and function correctly. Several videos on how to do it. Never opened a laptop before and I didn't break anything. Use it in my work in Florida every day. No longer have to run for shade to add notes or read something. Can sit by the pool and read RSS for hours. Add the extra memory to the S10-2 if you want a bunch of window open at once, otherwise base memory is fine. WIFI is very good for G.
Some nomenclature so at least you can sound like
you know what your are talking about.
Pixel Qi has three modes.
transmissive mode = back light on like regular laptop LCD
transflective mode = Back light turned down and good ambient light (Some say this is the best mode for reading.)
reflective = back light off. Ambient light used 100% to read the screen.
I use transflective mode when reading outside as it gives me a bit of color in the photos.

Matte for the Adam?
I thought there was not yet confirmation about the matte screen because of difficulties with green pixels, especially when the extra gap of the touch screen comes into play.
Also note that the Pixel Qi to be used in the adam is meant to be considerably better as it is the third? generation of Pixel Qi. (Maybe second by I seem to remember reading third?).
Even thougth it is very tempting to pre-order, It surely has to be worth the wait to see user reviews before going ahead and buying? I know I want one yestreday, but I am forcing myself to wait... Painful as that is!
I believe he said matte, just not how much matte
In blog when talking about matte screen he says"
"We told you how much we love Matt (that’s one reason why all the monitors here are from Dell). We have invested a lot of time in figuring out the right surface values which gives the perfect combination of 2 worlds (no reflection property of matt and scratch resistant property of glossy surface).
"It took us really long and was really harder for the manufacturers to make what we wanted. We can’t compromise on few things and this was one of them.
"(You need to open it in another tab and see it full screen). If you can see (I hope you do), you will see small green fringes and speckles. Matt surfaces don’t work well with Green colors and creates diffusion around green pixels. You Dell screens look good for two reason, one they have done good job and two, they don’t have to deal with the gap of touch screen in LCD monitors. Gaps add more refractions. Please see the next illustrations for more understanding.
"We have done a good work when it comes to both of these issues and you can observe the same in the final product".
I believe he has said the screen will be matte. It is a question of "how much matte" that is open to interpretation.
Generation
"Also note that the Pixel Qi to be used in the adam is meant to be considerably better as it is the third? generation of Pixel Qi. (Maybe second by I seem to remember reading third?)."
There really is no way at this point to figure out what generation the screens are. All she has said is that Adam will have "their latest and greatest." I have the Makershed "do it yourself" version which seems to have a wider viewing angle than what they were calling their 1st generation at CES 2010. Was this first gen. production, off the work bench, out the door" Who knows.
On one of the Qi videos they have one version they are showing off they called their "next generation" and then they go inside and get another newer version to show off. This was back in the summer.
Adam could be getting 10th generation for all we know, but at least we will be getting her "latest and greatest". I am sure we will be getting the screen they will be showing off at CES. Would not make sense for them to dis their best customer by showing off a better screen than was coming out on a product that was just starting to be shipped.
I see both of these companies going far, Notion Ink and Pixel. Eventually you may even see Pixel displays on smartphones.

Had a quick question I was hoping some Nexus S owners could help with, to do with the screen's pixel layout.
Pretty much every LCD display I've seen has its pixels lined up in neat horizontal and vertical rows (basically in a '+' configuration). Looking at the AMOLED screens on the HTC Desire and Samsung Galaxy S i9000, they both look like their screens have been rotated 45 degress, so that the pixels line up on an 'X'. This means that straight horizontal or vertical lines actually look jagged on an AMOLED phone (as opposed to diagonal lines looking jagged on normal LCDs).
Having seen the Nexus S in videos and photos, I think it may have a more normal, LCD-type '+' pixel grid. Can somebody take a look at their screen (or better yet, take some up-close photos of straight horizontal/vertical lines) and tell us what they see?
The only way you'll see anything jagged looking is if you're looking at your phone under a microscope.

Agreed, and even then it's not like when you are looking at a G2 or MyTouch 4g screen you just cry yourself to sleep. I think they are still pretty good screens, but SAMOLED is like the switch from a tube TV to that nice Plasma, never gonna be the same.
What the OP is noticing is the different pixel arrangement that samsung decided to use for these SAMOLED panels... which is RGBG instead of the traditional RGB on most LCDs. It's also responsible for the type of 'jagged' lines, which in effect is not really jagged, it's just that there's more space between red and blue subpixels than on a traditional RGB layout so you see more gaps for certain colors.
I notice the fuzzyness that the original poster is talking about when looking at the Samsung Vibrant. Text just was not as sharp on the SAMOLED screen on the vibrant (and other amoled screens) as on LCD screens on the G2 or Mytouch4g. This is due to the subpixel layout of the SAMOLED screen. Some people notice it more than others.
The Nexus S screen does seem to be sharper than the Vibrant, at least on the demo I played with.
the OP is right. and the Nexus S screen is the same as Galaxy S in that matters. its not a +. more like X.
however, i find it really hard to notice it unless you get very close to the screen. you have a good eye man.
Yup, the mesh/screen effect you notice over the pixels are from their different pixel arrangements, called pen-tile arrangement. More info here: http://en.wikipedia.org/wiki/PenTile_matrix_family
The galaxy S phones, and the nexus [1S] use this pen tile arrangement. I think the only amoled display I've personally seen without the pen-time arrangement, is the nokia N8's, though I'm sure there are more..
Hi, all?
EK-GC100 had 4.8" HD Super Clear LCD
Some time i felt that it seems like Pentile (Especially on White Screen)
So i magnified the GC's screen through the webcam!
http://forum.xda-developers.com/attachment.php?attachmentid=1992878&stc=1&d=1369584846
▲Galaxy Camera, EK-GC100, 4,8'(1280*720) HD Super Clear LCD (WRGB/BRGW)
As a Result
I can take the picture of GC's screen & GC's Screen was WRGB type LCD
It seems like the screen was composed of WRGB,BRGW's Double Array
And then i think
WRG
B is one pixel
RGB
W is another pixel
May be Put int the 'W' LED into normal RGBtypeLCD, Samsung can increase the birght of Screen but i cannnot appreciate that, it isn't amoled screen it's LCD screen. and i wanna Real HD Screen Not pentile, in addition it is unpleasent enough Cuz i felt that, Screen is pentile. Anytime...
So,,,The Conclusion is 'Samsung Galaxy Camera's Screen is WRGB Type Pentile Screen'.
What about your oppinion? (And Sorry for my ENG)
I don't know their exact reason for going with pentile, but for cameras LCD is better because colors are more accurate.
OLED screens are much harder to calibrate properly.
im lookig forward to buy this phone. just want to know if its display is IPS or just a regular Lcd panel ? is colour quality same as 2013 moto g ?
First of all, there is no "regular" LCD screens. All LCDs use some type of screen technology, wether it's TN, IPS, PLS, VA or something else.
That beeing said, the Moto X Play does have a IPS LCD.

by regular i meant TN/tft etc. since those doesn't have great colours and viewing angles.
I received my Axon 7 on Wednesday this week. The AMOLED screen does have very good blacks and looks vibrant, but there is an issue I haven't seen discussed - I'm trying to determine if its just my phone, an issue with AMOLED in general, or perhaps a coating specific to the Axon 7:
When I view the phone directly, whites look correct (warm, natural or cool depending on the Display setting). However, turning the phone even a little off-axis, 10-20° either vertically or horizontally, introduces a very small blue shift - whites especially take on a bluish, sort of washed-out cast. It makes the colors seem much more shallow and unreliable. Can those of you who received your phones go to a WHITE or light-color screen and report if this happens for you too?
This is actually hard to identify, most people will just see something is a little "off" - to my eye, it looked like a very subtle version of a TN-panel color shift. I never have seen this on an IPS panel, though off-angles may get washed out (see Nexus 5/5X) quickly at 50-60°, they always retain their color, even if it lightens. Or, e.g., the Moto X Pure 2K IPS panel that I'm coming from has zero off-angle color shift, no wash-out, and just darkens a little even at 180°. This is my first AMOLED panel, so I'm not sure if it happens often.
If anyone can help me determine whether this is a defect or an expected limitation, that would be great.
I've noticed it on my A7 too. This is my first AMOLED phone, so I too am not sure if this is normal.
I see it also. Thanks a lot now I won't be able to insert it.
For now I will blame the screen protector that came in the screen.
Welcome to Amoled.
The cheap screen protector contributes too,
Thanks, all - I guess it's just the phone then. I actually don't have the screen protector insert applied, so I assume the "screen protector" refers to the factory glass overlay.
Does anyone know if even the new Samsung AMOLEDs exhibit this shift? I think the Axon 7 is technically a Samsung panel, but I wouldn't be surprised if Samsung kept the best AMOLED technology for themselves.
Not sure this is a dealbreaker, but it's definitely a step down from the great color-true viewing angles on the Moto X Pure. (Too bad Moto abandoned the good design the Moto X Pure had for gimmicky snap-on modules this year rather than iterating - it seems like the Axon 7 is otherwise the spiritual successor to the MXP.)

Of course Samsung keeps the top production panel for themselves... However, it's still a great panel according to colorimetry tests.
Don't notice it on my unit. Jumped from a galaxy S7 edge to the Axon 7 and the display looks exactly the same to me.
This is an area that has driven me a little crazy. I'm used to my Samsung AMOLEDs (Note 4, Note 3, S3, etc.), and they don't have any noticeable "shift", This screen is gorgeous, but it's not a top-tier Samsung panel (obviously). Still, small price to pay for a 400 dollar savings over a Note 7. I am also positive the matte screen protector isn't helping. Once my tempered glass one gets here, I will switch it out and see if it makes a difference.
Which tempered glass screen protector are you getting? I have not read one good review for any of them...yet.
As an update, I went and tried some floor model Galaxy phones at the mall, and they actually had worse off-axis blue shift. Not sure if that's because of the initial screen quality, or that it got worse over time.
Does anyone know of any AMOLED phone (specific model) that does not have any perceptible shift? Does anyone know if the shift gets worse over time?

I believe others are correct that it is the cheap screen protector. Plastics is refracting the light leaving the phone. Since blue light refracts more (the reason the sky and sea is blue). you will then to get more blue especially at certain angles.
I don't think tempered glass of the same thickness will make a significant difference but i do recommend getting a tempered glass protection because the cheap plastic one will surely be scratched very quickly. There a lot of things that will cause increased color shift, but I am not sure its a huge issue. I don't think accurate color is needed off axis. I could be wrong. I typically only look at the screen off axis when I am trying to take a odd angle picture or too lazy to move when I am in bed.
If any one does find a screen protector that distorts less please let us know.

The first thing I did was remove the screen protector, and I still notice a blue-ish shift at angles. It's minor though, and it's definitely not a dealbreaker.

AMOLED screens are typically like that. When I get on the bus and see people using their galaxies, it always looks cyan from an angle. LCD technology loses contrast at angles, whereas AMOLED has chroma shift.

Just to be clear - the color shift happens without any additional protector. Someone else used the word "protector," but I only have the bare Gorilla Glass in front of the AMOLED screen, no plastic or other layer added.
I see it as well with no screen protector on.

I never understood why phone makers use glass. Just make it plastic with a removable glass screen protector that the user can replace if broken. My GF dropped her phone, The tempered glass protector broke but protected the glass screen.
I do like that the S7 active has a plastic screen just wish all companies did this.
Hello,
I have the same issue with 5 devices I was testing. Every Axon 7 had the issue with the color shift from a red tint, to a blue tint when tilted.
Is there someone without the issue or is it really normal?
