The above-mentioned optical properties are of course the basic requirements of LOCA adhesives. The next challenge is to be certain that these optical qualities will be retained and consistent over time under real-world operating conditions. It is in this regard that b* number becomes a useful tool. The b* number is especially important in its consistency over time as yellowing of screens is considered highly undesirable and indicative of aging or failure in the eyes of consumers.

Many environmental conditions have been shown in the past to lead to a yellowing of LOCA materials over time and a corresponding deterioration in image quality. By measuring the CIELAB coordinates of a given device after initial manufacture, it is then possible to expose the device to harsh conditions and measure any changes in CIELAB numbers.

Each of these tests and all of them combined is designed to simulate years of real-world aging in environments such as in automobiles and appliances. By showing consistency over time under these conditions of the b* value, manufacturers can be confident of resistance to yellowing for LCD displays. In addition, customized testing is not uncommon in cases where a product may be exposed to unique or especially harsh conditions.

What your picture shows is two screens with different white points; the system on the left has a cooler white point (bluer white) that the system on the right (warmer white point, so yellower white). Neither is wrong - they are just different.

You can calibrate the screens. The best way to do this is to use a hardware colorimeter or spectrophotometer with calibration software, but a good quality system along these lines typically costs around US$150 and you can spend up into the thousands for spectrophotometer based solutions. I use hardware calibration here on screens intended for colour critical applications and the results are amazing, but this is well out of the range of most people. Most users tend to think that very blue (cool) whites are desirable on computer screens so would probably regard my properly calibrated and profiled screens as a bit yellow and perhaps also a bit dim; I follow standard industry practice for the majority of applications and calibrate to 6500K white point which is approximately daylight white.

A typical low to mid end notebook screen doesn"t perform well enough to justify a hardware calibration setup unless you can get an older one second hand, are aware of its limitations and figure out or know how to make it work with Windows 10. I am not going to offer instructions for the setup I am thinking of because you need some knowledge of colour management concepts to understand the limitations in what you are doing, also it is a faff to get the drivers to install.

Assuming calibration using hardware is out of the question, the next best thing is to follow the instructions @Riddle_Decipher posted, though be aware that whilst the process is described as calibration, it is not calibration to an objective standard but merely tuning the screen by eye to provide more subjectively pleasing results.

I highly doubt there would be this much variance on true original Apple screens, this looks more like what everyone always says about “you get what you pay for” in aftermarket screens.

Dymax Light-curable Optical Display & Touch Screen Laminating Adhesives are specifically formulated for applications where durable, crystal-clear, invisible bonds are required. Their fast, on-demand cure allows substrates to be repositioned precisely until parts are ready to be cured. These one-part LCD adhesives are designed for touch panel assembly including bonding flat panel displays, LCD screens, tablets, outdoor kiosks, navigation systems, liquid crystal displays, kiosk panels, mobile phones, and smart connected devices.

The Dymax family of Ultra Light-Weld® Optical Display and Touch Screen Adhesives are available in varying viscosities for use in flat panel display bonding where bond strength, non-yellowing, and re-workability characteristics are important. The two low-viscosity materials, Dymax 9701 and Dymax 9702, offer easy-flow characteristics for panel laminations while Dymax 9703, the higher viscosity product, is available for damming requirements.

These adhesives feature “on-demand cure” with UV/visible light which means that substrates can be repositioned precisely until parts are ready to be cured, while using a thin layer of adhesive controls cost and can reduce the weight of the final product. LCD adhesives help reduce air entrapment and bubbles to create strong, ripple-free bonds that help increase panel strength – they also  act as a barrier against stress, significantly improving product reliability and warranty costs. Optical Display & Touch Screen Laminating Adhesives are suitable for bonding – glass/glass, PET/ITO glass, CAB polariser/acrylic, polycarbonate/polycarbonate, glass or polycarbonate/CTA, polycarbonate/mesh/polycarbonate.

Other characteristics include: non-yellowing for increased light transmission, enhanced brightness, optical clarity, and better contrast ratios; excellent bond strength; superior re-workability for easy removal or repair; easy flow characteristics for flat panel lamination; excellent thermal shock resistance; and low shrinkage which minimizes visible distortion after cure.

The LCD preview screen can show something different than what will actually be recorded. This often happens with the more consumer-oriented cameras that try to make everything look nice on the screen. Turn off the pretty stuff, read the histogram instead of relying on the screen brightness, calibrate your colour balance, and never rely on Automatic White Balance to do everything for you. Of course, if you showed a reproducible example of the problem and explained the method by which you took the photograph, someone might get a clue about what is actually causing the colour shift.

Canon EOS 6D has problem with yellow tint lcd, i can"t custom WB with lcd, when i see the image on lcd is warm but when i shooted and preview on macbook or iphone, this became blue than the lcd, what happened with my lcd, i bought it 2 week ago in Vietnam, i compared it with another 6D and my camera 6D is more yellow tint than another. Who can help me dicuss about it and how to fix theme? I feel sad now because it bought from my salary and i am a student in college! I search on Google and the image same my problem, my camera same with 5DSR.

Looks like that"s how the LCD was designed.  How do the photos look on the LCD when you set the Kelvin to 5200 or Daylight?  Do the photos also look ok on the Macbook at 5200K?  I think you"ll find that most camera LCDs will have a different temperature tint to the laptop or phone display.  Hopefully it is not too far different.

Jasmine Atcho, an iPhone lover, bought iphone12 with great enthusiasm and ended up in disappointment. The iPhone yellow screen was fleeting at Jasmine. It was a terrible thing for her and against her expectations. She is not alone in the queue.

You must be wondering why the iPhone screen looks yellow? Why does a world-famous company have such a fault in their high-selling product? We will try to find some genuine reasons. Maybe there would not be a significant fault as you are thinking.

If you have a habit of switching blue light filters daily, it can make the screen look yellowish and even cause yellow dots or spots on your phone screen.

Whenever we have an issue, we think that it must be with the rest of the world. It"s not the case. Many Apple users are complaining that my iPhone screen is yellowish. But the fact is that not all iPhones have that problem. Luckily, there are some simple settings by which you can set that unwanted iPhone yellow screen.

You might be wondering what white point has to do with yellow tint. It"s all about adjustments and settings. There is no drawback of changing some settings to control the iPhone screen yellow tint.Another solution can be to reduce white points. It"s easy to do so.

The best part is that you can increase or decrease the intensity of bright colors as per your likeness. It will make your screen color look much better.

The 3rd simplest solution to fix the iphone screen yellow tint is to update your phone. As you know, any phone company like Apple or Android gives options of updating the system after every few weeks.

If you have tried the above three methods and your iPhone still sticks in the yellow screen of death, you"d better use an advanced tool or contact Apple support directly.

One of the best tools to fix the iPhone/iPad yellow screen of death is iMyFone Fixppo. Fixppo fixes not only iPhone stuck on the yellow screen of death, but also many other iOS problems like: safari keeps crashing iPhone, iPhone WiFi keeps turning on, iPhone camera turns on by itself, and so on.

Step 3. It will take a few seconds to verify the firmware and extract software before fixing it. Then click Start and wait for a few minutes until the screen shows successful.

It"s not too bad that the iPhone screen looks yellow, but it must not be yellow all the time. The yellow screen can look better at night time only. There can be many reasons for the yellow tint.

Some iPhone 7 and iPhone 7 Plus screens appear very yellow, or at least seem to display a much warmer color spectrum than what many people were used to on a prior iPhone display. If your new iPhone has a yellow screen or a warmer display, we’ll show you how you can color correct the iPhone display quickly and do away with any yellow screen tint.

Before proceeding, realize that on some occasions, select prior iPhone and iPad devices have had a yellow tint to the screen that seemingly resolves itself over a several day period. Supposedly this is because an adhesive on the display is not yet entirely dried, which can cast a slight yellow color hue onto the display. If this is the issue, it should resolve itself just by doing nothing other than waiting a couple of days for that glue to dry. Consider this before adjusting the iPhone display color hue as we’ll cover next.

Adjusting the color tint intensity and hue should let you quickly get to a display that does not have a yellow tint or warmer hue. You can also easily overdo it and get a very blue cooler screen, or an ultra warm screen, but adjust away according to your own visual preference.

You can see a few different examples of the yellow screen side by side before color correction, the regular color iPhone 6S Plus is on the left and yellow tint iPhone 7 Plus is on the right. These pictures were taken with an iPhone 6 Plus so they’re not going to be the most amazing photos in the world, but they do demonstrate the notable difference in screen warmth:

Do note that if the earlier mentioned adhesive screen glue drying thing is legitimate (and not just a longstanding rumor that seems to recirculate with every iPhone and iPad launch), then your iPhone 7 or iPhone 7 Plus display is probably going to look oddly cooler in a few days, so you’ll probably want to return back to the Color Tint settings and either turn the feature off, or re-adjust it as needed.

The ability to adjust color tint on the iPhone (or iPad) screen is a new feature to iOS 10 and it’s really quite nice, sort of similar to how calibrating a screen on the Mac works in Expert Mode with precise color adjustments. Since adjusting the screen tint to be slightly more cool seems to do away with this yellow display tint, it makes you wonder if the iPhone 7 and iPhone 7 Plus display was just color calibrated to be warmer to begin with. Time will tell, because if it’s just a yellowish screen glue thing, it’ll go away on it’s own shortly.

Did your iPhone 7 or iPhone 7 Plus screen have a yellow tint or warmer hue? Did you use the color adjustment tip to fix it? Let us know in the comments.

Mark, thanks for your feedback. I’m sorry to hear that the Color Filters setting doesn’t fix the yellow screen issue. Have you tried to bring your device to an Apple Store and ask for a replacement unit?

I have the same issue. My iPhone 6 (which I am replacing) has a much better display than this new iPhone 12 Pro. The latter has a yellow screen and way less clarity. Such a disappointment,

Hi guys, sadly I do have the same problem… called apple care and “discretely” after 15 minutes chat, the operator confirmed that lots of cases are arising around the yellow screen. He fixed me a meeting in the closest apple store in town and I went today. At first they have recognised the problem and after several trials they decided to exchange my iphone. Those on display were perfetc and I felt really happy and relieved only until discovering that the new one they gave me had the very same problem!!!

P.S.: iOS 14.2 has just been released. We recommend you to update and let us know if by any chance the yellow screen problem is fixed by this update: https://www.iphonetricks.org/ios-14-2-software-update-10-features-15-fixes/

Just got my iphone 12 today… set it next to my iphone X to do the file transfers and I was shocked at the difference in screen color. I figured it was a setting so i finished the transfer and went through all the display adjustments/corrections stuff… then googled and found this forum. Tried everything… the display is simply not as good as the iphone X i have. Sigh apple. Another reason to never buy the launch!! I’ll be going to At&t to hopefully get it resolved.

I am having the same trouble with the screen color. I am replacing an iPhone 7. The screen on the iPhone 12 mini is like sepia, AFTER we adjusted all of the settings to make it white. I have been talking with support for over 2 1/2 hours. They have basically told me to return it and buy a different model. They say they have not seen any issues with screen trouble with this model. I don’t believe them. I am so frustrated.

Marcia, thanks for your feedback. So, the iPhone 12 mini is affected too. Until now we only had reports about the iPhone 12 and 12 Pro yellow screen occurring. It seems that the later released 12 mini and 12 Pro Max can be also affected by the low quality OLED manufacturing standards. We know how frustrating this is. Hope you can get a replacement unit soon, one that doesn’t have the same problem! Keep us updated.

I received my new iPhone 12 Pro Max yesterday and was really disappointed with how yellow the screen was compared to my XS Max. It just felt yellow and dingy.

CornishTD, thank you for confirming that the iPhone 12 Pro Max yellow screen problem is a fact. I’m sure that you would have preferred not to have a reason to write this comment. And yes, we know the feeling. Spending such a big amount of money implies high-quality. But apparently sometimes even Apple fails to meet expectations. I hope that this will be sorted out for you and you’ll get a replacement when stores reopen in the UK. Stay healthy!

Got my 12 pro max on launch day, soon as I switched it on, I could tell screen was not right, got in contact with apple ( via online chat), sent the guy pictures, he said it was normal lol,

Hi, I received my iPhone 12 mini on the 13th and when I switched it on I immediately noticed the dim, washed out, greenish/yellowish screen. I work with colour calibrated screens as I’m a photographer and the colour cast on the screen is just unacceptable. People’s skin tone on photos are greenish/yellowish. The text on the screen is not black but grey and in darkmode the text is not white but yellowish. It’s really ugly.

With True Tone enabled the screen turns almost to orange. So True Tone is useless too. But that’s less of a problem as I didn’t plan to use True Tone.

And I noticed that while booting up the phone, when you see the Apple logo, that the screen blacks goes from grey to black. This is also visible while watching videos. The blacks are not black but grey for a few seconds and after that they go black. I thought blacks on oled screens were supposed to be black, not grey?

I’m very disappointed. I’m replacing my iPhone 7. But the 7 has a better screen. I did send the mini back today and I’m waiting to receive a new mini, but I’m not having high hopes after reading all the screen problems!

we got two iPhone 12’s and surprisingly one of them has this issue. We could compare both screens side by side and trust me Apple has done a worst job with these displays. Surprisingly Apple service centre was not able to identify the issue till i actually made them compare both the screens. They confirmed that Apple does manufacture diff screens for their devices but are not ready to give it in writing nor they are ready to replace the device. Being an Apple user for ever, i feel terrible that Apple could do this with such expensive devices.

I have the same issue. 12 mini arrived today and after setting it up I was surprised my iPhone 6 screen was whiter and brighter! it’s so gutting after waiting 4 years to update my phone . I’ll be contacting apple this evening.

Hi, just going back to iPhone and got a 12 and was really disappointed at the yellow looking screen compared to my oneplus6t and my iPad Pro. Messed about with it all day then found this. It has made a huge difference now it looks proper white again and now makes my oneplus look off.

I have the same issue yellow hue on screen in comparison to my old iPhone 11 when True Tone turn on. If turn off True Tone then screen is ice blue hue. Even the full brightness is just 80% of old iPhone 11. Let me know if someone is feeling brightness is not as iPhone 11 or earlier.

I have received my new iPhone 12 mini one week ago, as a replacement for my old iPhone SE (1st series). The same day I also received an aftermarket screen protection which filters blue light, and I installed it as first thing, just to put it on a new screen with no dust. Immediately after turning the new phone on, I had a feeling of very yellowish screen, and I started to swear against the screen protector! Before contacting the shop to return the screen protector, I decided to remove it and see how much difference it did, and I was very disappointed… the protector didn’t affect the colors at all, thus it was the iPhone screen. Unfortunately these protectors cannot be removed and reinstalled, thus, just for this, I had to throw away a brand new protector. I tried everything, some settings (like turning True Tone off) improved the situation, but the screen remains absolutely not comparable in terms of brightness and clearliness with that of my previous iPhone SE. I called Apple, had to talk to 3 different people, losing more than 2 hours !!! The first, after explaining the issue, made me wait… after 30′ wait, the line was cut, so I had to recall – the second helped me better, he didn’t recognize there is this issue, but proposed me a replacement unit – I agreed, and I had to talk to a 3rd person (after sales department), who at first told me that a replacement was not possible because my device was not broken, but afterwards corrected, as my phone was less than 14 days old, and agreed for a replacement. I am now waiting to get the new device, but I’m terribly afraid that it will have the same problem, I hope not, anyway, I did never expect such issues with Apple, and with a phone which costs 700+ Euros!

Thank you – I messed around in the color area as noted above and this fixed the yellow color cast. I am a graphics professional and having a real clean color for the screen is important. I appreciate your help. Hopefully this does not revert back.

Squall, thanks for a lot of this in-depth iPhone 12 yellow screen workaround. I’m sure that other readers appreciate your tips too. We will update them in the main article for better exposure. Apple has been notified about this.

I recently upgraded from an iPhone 12 Pro Max from an iPhone 7 Plus. I noticed the warmer tint after getting the phone home, after turning off True Tone, my screen is a very nice warm white. I was curious about this, and what I was able to find was that apple did the warmer tint intentionally, and I also had heard the reports of Apple acknowledging this as a software problem. Plus This was my first OLED panel, and wanted to check on proper behavior.

I had a Plasma TV for several years and always remembered, it was always warmer than LCDs So I figured this was just normal OLED behavior since there wasn’t a Backlight.

4. So my conclusion is for myself anyway is, true tone exaggerates warm lighting, or even darker environments and turns the screen too yellow, turning this off, gave me a nice warm display that I’m used to looking at, and video looks great the way it should on a calibrated display.

Clinton, thanks for enlightening us and for sharing these clever iPhone OLED panel testing tricks. I’m sure other readers will appreciate them too as it makes it easier for them to self-diagnose if the iPhone 12 yellow screen problem is hardware or software related. We will share some of your contribution in the main content of the article.

My Iphone 12 pro max also has the worst yellow tint when true tone is on, as compared to my 11 pro max. My son just got his today and it is perfect like his 11 pro max too. Ours buying date was 4 weeks apart. Mine was F2LD and my son is G6TD serial number (I don’t know if it has anything to do with the production code). I did some googling and finally tried to fix the yellow tint and I found it working. Try: Setting>Accessibility>Display and Text Size>Color Filters (on)>then click on Yellow/Blue Filter. Mine works well. I compared my screen with my son’s screen. I even found mine whiter than his even when true tone is on.

Yes my 12 pro max also have that dull display, this is the first time that i got an iPhone and to get this kind of quality at such a higher price is horrible. Unfortunately i cannot return this iPhone because I am from Haiti and getting this iPhone come to me basically expired the 14 days return policy. I try hard to overlook this issue but the screen is simply not pleasing. My iPad has better screen quality and colors than my iPhone which is ridiculous!!!!!

The first two I received were really really bad – low contrast, low brightness, yellow with True Tome off, very yellow with True Tone on – a massive step back from my iPhone X. The next three have all been the same as one another, pretty much, but much better than those first two – small variation in brightness between them, but as bright as my iPhone X. With True Tone off, the screen is pretty close to white. With True Tone on, they are still yellow in nearly every situation.

Some people prefer the look, but that is not the point – you can use night shift (which is adjustable) if you like that look – its very similar. True Tone should attempt to look white in all lights – place a white hanky next to it – the screen (where it is a white background) should look the same as the white hanky in all lights; with True Tone on, the iPhone 12 does not. It looks like a Kindle Paper White. The white is off white – great for books, rubbish for photos. Have a “Book Mode”, call it what you like Apple, but do NOT call it True Tone. IMO, Apple has no intention to fix this and apart from those early panels like the first two I had, there is no hardware issue and there is no intention to fix it.

Just got my Iphone 12 Pro 2 days back. Noticed that my screen was very yellow (too warm for my taste) , especially with true tone on. I have tried turning true tone off – and the level of “yellow-ness” does reduce. But when I compare it to my iPad Pro 11, the difference is very clear – my iPhone 12 pro is very yellow compared to the iPad.

I got a new 12 pro max. The moment i opened it from the box it had this weird dingy yellow low contrast panel. I came from 11 pro and it had a much better overall color accuracy. Apple store decided to replace my phone with a new one…But the screen is still even more yellow on my replacement model. Total dissapointment for a thousand dollar phone.

I have a 256GB 12 Pro Max and also experiencing this. I finally upgraded from an iPhone 6 and that had a replacement screen that wasn’t even official, just a cheap one, and that screen is better than this new £1300 phone! Spent all day looking at people having the same issues. Absolute disgrace from Apple this.

I just got an iPhone 12 pro, upgrading from a 6s and comparing side by side there is a clear difference in contrast and I am having a yellow cast issue as well. I noticed it right out of the box but I thought it was true tone. I turned it off and it still doesn’t look right. I tried the color filter but it only helped a little bit. Main issue for me is the lack of contrast. I have noticed that if I have auto brightness on and shine my 6s flashlight on the ambient light sensor then it will brighten up and the contrast and colors look much better and closer to what I’m used to but I don’t want to have to keep my screen at maximum brightness to keep it looking right. It seems like a replacement probably won’t help either considering the previous comments with little to no success with replacements. I have heard that for some the iOS 14.5 beta has fixed the yellow cast issue but we’ll see when it comes out. I also have a pixel 3a which has an OLED screen that looks great, with vibrant high contrast but I have noticed that at lower brightness levels the colors shift a lot warmer so it may be the way the software interacts with the hardware that is causing the screen to not display properly. At least I hope it’s a software issue but considering how long it has been since release there is little hope left for that.

I am a photographer and iPhones has always been a good color test for my images. The screens were perfectly calibrated (4, 6 Plus, 7 Plus). Now I got 12 Pro Max (iOS 14.5.1) and colors are rubbish. Yellow tone and I can’t unsee that anymore. What is more. When changing the view angle colors turn to bluish. That is absolutely unacceptable. This is what the cheapest monitors do. I am extremely disappointed. “Color filters” was not helpful as well. Adjustments are too extreme and it is not possible to to reduce that a bit yellow tone. It turns to blue/green/red, but not that neutral which is needed.

Thanks for sharing your findings about the iPhone 12 Pro Max, from a photographers point of view. Sorry to hear that the tweaks mentioned in the article did not help out. If you manage to find anything else that can help with the yellow screen tone, don’t hesitate to follow up.

I purchased a 12 mini back in January 21. I experienced cell reception consistency issues reported on different blogs but also noticed the yellow screen tone. Ended up returning that unit. Purchased another 12 mini last week and again noticing the yellow tone on this unit as well. Both purchases were from 3rd-parties. To the naked eye and next to my 11 pro, both minis were noticeably yellower. I tried the white LED sensor flash described in earlier comments with my 11 pro and the 2nd 12 mini placed “sensor-to-sensor” (top edges together but both screen sides up) and found the mini’s maxed-out brightness still yielded a yellowed display compared to the 11 pro. This was with true tone off, night shift off, no filter applied, and white point reduction off. At this point I’m not sure if we all are crazy or not. Is this actually a manufacturing problem with the 12s or are we all just dissatisfied with Apple’s color calibration for OLED? Is that in itself a manufacturing issue? Further, I placed my 11 pro next to my 1st generation SE and what would you know, the 11 pro looks yellow compared to the SE, but the difference is not as pronounced as that between the 12 mini and the SE. That makes me think this screen yellowing is a characteristic of OLED panels, not just a manufacturing issue on 12s. Whatever the reason is, I prefer the SE and can tolerate the 11 pro but am having trouble accepting the 12 mini. Thoughts?

Thanks for the detailed feedback Jake. I think that the problem with accepting are your own standards. If you find it acceptable you should go for it. Else, not. Btw, we haven’t seen reports of the same yellow screen issue for the iPhone 13 mini. So, if that is an option I would pick it.
