iPad Who got a perfect screen on the Air 2?

[sanke1]

For me, perfect panel means
1. Neither blueish white nor too much yellowish white. I actually hate blueish whites as the colors look washed out and too much blue tinge hurts eyes while night reading.
2. There should not be any dead pixel.
3. The screen brightness must be uniform in all the areas.

Both my Air 2s have DM serial. Both have exactly identical displays and both were manufactured in the last week of November. Both are perfect as per my above 3 requirements.

That sounds about like mine except mine has the dead pixel. So you would say yours are warmer than the display units?

There are variations in every production batch (we don't know for sure even if Apple is using just one supplier or several), but the only way to say that is to put side by side your unit with the display unit at the Apple store, under the same light.

Mines are exactly same as display units and ironically, the display units were manufactured in last week of Nov 2014 too.

My ipad's displays are not warm. They are fairly neutral at around 5000k which I call perfect natural white.

How can you tell when it was manufactured? Is it on the box?

Can you please tell me know how to measure color temperature on iPad ?

I checked the color temp at a friend's electric shop.

Can you give me advice? I have 2 iPad Air 2 now, but I do not know which I should keep. Both of them are uniform bright, insignificant light bleeding and distortion. However, the left one is as yellowish as old paper while the right one is less yellowish. In portrait mode, when I look them at an angle, the left one is whiter while the right one seems to be pinkish or purplel.

Which iPad do you think best match your requirements? I like neutral and uniformity white.

If you are not sure then return both and ask for replacement due to screen issues. They do not look uniform in brightness across their screens.

But if you have to keep one, then the left one should do you just fine. Slight yellow is eye friendly compared to pink/purple hue.

Do they not look uniform? I can not recognize them. Can you show me the areas that are dofferent compared to others ?

I also prefer the left one but in the landscape mode, the left one looks very old yellowish while the right one is brighter.

I went throught a lot of iPads Air 2. A few of previous are good but I returned them because I upgrade to greater storage or Cellular. I returned some of them becuase pinkish hue. The last 2 ones were pinkish/grey haft.

In the pic they do look slight non-uniform. But it can easily be due to room lighting and camera angles.

Here is a screenshot of my two iPad Air 2s.

They look almost exactly like one another with maybe 5% variance in pic
But for me they are perfect and I cannot nitpick.

Yours look great uniform. Which should you keep?

I just took more pictures of mine. Full brightness in dark room with vavious angles

One more

The last one

Here's a pic of three iPad Airs. The top two are iPad Air 2 models, the bottom one is a an iPad Air 1. They're all on max brightness.

If you spent $1,000 on the top one and you compared it side by side to the bottom one, wouldn't you be at least a little bit annoyed? Wouldn't you want the crisp white shown in the middle one or especially the bottom one?

Does the bottom iPad Air have the DL or DM serial?

I am keeping both (DM Serial)

It's subjective for you. If you are not satisfied then go for an exchange. I personally would keep the slightly yellower as it's easy on eyes.

Both of them are DM

Below are five of my family iPads. From left to right: iPad 3, iPad Air 1, my sister iPad Air 2, my yellowish iPad Air 2, my less yellowish iPad Air2. All of them are DM

Which should I keep between the rightmost 2 iPad Air 2?

Actually, I did prefer the yellowish, which I got from apple store while the less yellowish one was still in transit, but the right one is brighter (at 0 angles) than it.

I would keep the 4th one from left. You are finding it yellow because of the presence of pink/purple ipads in that lineup. It's all comparative.

Even my iPad Air 3 was purple to the point I hated it and sold it in 2 months.

I do not understand why I juxtaposed between the 4th one and displays at apple store and bestbuy, I also saw that mine is really old yellowish while the displays are bright white.

When I compared with my sister one(the 3rd), they look nearly identical exept my sister one is more neutral.


In reality, I do not see any shift in color or brightness on the 5th one while I recognized the 4th look more yellowish at the bottom area.

It is a hard decision.

What a quality control disaster for Apple. They all should be in the same ballpark.

It sound terible, but it is true. All iPads are different in color temperature when juxtaposing them, so it is almost impossible to say which one is neutral white which is yellowish and which is pinkish.

The longer I use one of them, I feel it white bright and uniform. However, when I justapose least 2 iPads, I recognize there is a huge difference between them. One is pinkish others are yellowish or grey. For example, I thought my last iPad Air 2, which I got on 12/11, is cool white and uniform until I set up my sister iPad Air 2 on Christmas Day. When I justaposed mine and my sister's one, I found out that mine was pinkish haft and grey haft (Its top area was pinkish while the bottom was grey)Fu**

Now, after inspecting these 2 iPad Air 2, I found out that none of them have dead pixel, shift in colors, significant light bleeding. They are almost uniform. The only difference between them is different degrees in yellowish tint. The least yellowish iPad has least light bleeding (almost non-existent) while the most yellowish has a slight light bleeding at the top right corner.

So what's your problem?
You don't have to work on both simultaneously.
If they are both uniform, without dead pixels, without color shifting or light bleeding, what's the problem in have a slightly different white temperature calibration on a consumer grade device?

----------

This is what mine looks like next to the display model under the same light.

Your is warmer, but uniform.
I can't see a problem on any of the two iPads showed.

Do you really think that millions of consumer grade displays could be calibrated in the same exact way ? Do you understand that the shift between the two units is, in term of white temperature, minimal ?

I would keep the one you are calling yellowish, that isn't yellowish but just warmer.
It seems to be the best of the five, and I don't like cold calibrated displays.

You always try to downplay Apple on every single post you write.
There is no quality control involved here. The displays are all fine and well within production margins.
Screens comes from multiple suppliers/batches and are calibrated as intended for consumer grade use, not photographic professional use (for that people use big monitors with calibration tools for a total value of SEVERAL THOUSAND DOLLARS).
