lcd screen green tint made in china
Many Xiaomi users have reported issue with their AMOLED displays showing a green tint. The problem resides on the hardware side, meaning it is a chronic issue and not caused by the users. We will provide you ways to reduce this tint in this article.
AMOLED displays are a type of LCD display that uses organic light emitting diodes (or OLEDs) to produce image displays. The displays are often used in smartphones because of their high resolution, wide color gamut, slim form factor, low power consumption, and lack of backlighting. AMOLED displays are known for their green tint, which can be a problem for some users. The green tint can make viewing the display uncomfortable in certain conditions.
Xiaomi has become quite famous with green tint issue on its AMOLED devices. It is still an ongoing issue that we haven’t had any real resolution to. The most widely known device to have this green tint issue is POCO F3 also known as Mi 11x or Redmi K40 and it is totally random. Of course this issue is not specific to POCO F3 but spread over many other AMOLED devices.I recently bought a Poco F3, and I’m trying to find if the green tint is a common issue or I have bad luck. To check it: select in color scheme->advanced->enhanced, turn the brightness very low, and turn on dark mode. Then go to the phone app or one with a solid gray color.Source: Green tint on screen
Green tints are hard to see on higher brightness values and daylight. To check whether you have it or not, you need to lower your brightness the lowest and turn off all the lights in the room. It has to be really dark. After that, you might check it on Google Chrome’s secret mode tabs.
Xiaomi has been rolling updates that help with this tint, reduce the visibility, however it is still there and and it seems to be there to stay. So, if you already have it, your only option to completely get rid of it is to replace your screen. The problem with that is some users still continue to experience this green tint even after replacing their displays so it is not a guaranteed way. However, there are a few ways you can use to reduce this tint. Let’s get to it.
Using screen at 60 Hz makes the panel LEDs of the phone screen have higher power. If you use it at high Hertz values, your screen LEDs will get tired and will not give correct colors. So use it at 60 Hz.
After these procedures, you will minimize the screen greening problem. If you are not satisfied with the screen of your device, take your phone to the official Xiaomi service and request a refund. If you don’t know what 60Hz or refresh rate is, check out our What is Display Refresh Rate? | Differences and Evolution content to know more about it.
While reducing this green tint is possible, getting rid of it entirely is quite tricky and requires time and luck as we previously mentioned, the problem can still occur after a replacement of the display. However, the hope is Xiaomi will remove this issue in the later upcoming devices.
A smartphone user with a device that features an OLED panel might be liking the bright colors, beautiful and vivid panel, deep blacks, and reduced battery usage that comes with the inclusion of an OLED, but, the one major issue which hits a lot of (not all) and that is color tinting of the display or more commonly known as Screen Tinting.
Today, we will be discussing what Screen Tinting is, especially green tint as this is the most common phenomenon, especially in OnePlus devices. We shall also list out the reasons for screen tinting, and provide some methods to fix the same. So, without any further ado, let us begin with the article.
Before we discuss what exactly Green Tinting is, we need to discuss when screen tinting is evident. Considering, without knowing when and where green tint occurs, you cannot talk about how to fix it. Usually, Green tinting is visible only in low lighting with the device at reduced brightness of about 15-20%. In very rare cases, you might see the tinting in proper lighting, but that is like a needle in a haystack.
Do note, we keep saying green tinting because it is the most common, but there are other tints that might occur on a screen, one of the major ones being pink tinting. So, once you have understood when green tinting is visible, let us discuss what it is in brief.
To put it easily, Green Tinting or any kind of tinting is a hue that develops on an AMOLED display, wherein the tinting or hue is visible when the smartphone is under 15-20% of brightness. This does not occur all over the screen and is more evident on certain sections of a display. As Evident by the definition of Tinting on Wikipedia (Tinting is to slightly change the color of something) there is a shift in the color of a display in certain parts of the same.
Now that you know what Green Tinting is, why not discuss the reasons for the same. Before we discuss the reasons for tinting, one must understand the process of making the display, color calibrating it, and what causes screen tinting.
As mentioned above, screen tinting is caused due to another process that takes place while calibrating the display. To allow OLEDs to display colors there is a process used known as shadow mask patterning.
Within this method, there is a deposition of RGB emitting layers on each and every white pixel available on the display. The white light is filtered via the RGB deposit based on the color to be displayed. To do this, Red, Green, and Blue layers are arranged, which emit light in the pixels of the OLED display. This also means that each sub-pixel has individual colors.
Now, this is getting too complex for our liking. While reading all these display related things, you might be wondering, why is this important? Does this play any role in the screen tinting issue? Definitely, Yes, so, let us get into that without drifting to all these technical terms.
The above-mentioned process explains the cause for the screen tinting. The colored layers mentioned above are deposited on the LEDs using a special stencil referred to as the color mask. If the mask, which is important in this process, is disturbed and or not placed accurately during the deposition, there can be a major error in the spacing process of the color deposits, which causes a non-uniform color output on the display.
Also, there is no necessity of the tinting being green, considering some other devices, such as the Asus ROG 2 featured a pinkish tint in some of the units of the device. So, now you know what is screen tinting and how it is caused, you might be wondering how can you fix this? Let us list out a few methods to fix the screen tinting.
The simplest of the methods to fix screen tinting is to return your device. Sometimes you just get unlucky and receive a defective unit. If so, do not throw away your phone box, preserve it and, ask for a replacement from the service centre. Usually, the brand is aware of these issues and the technician at the service centre shall check the device and, when you show them the screen tinting, they will take away the device and issue a replacement. This is the easiest way to get rid of screen tinting.
If the whole display is tinted, this is not screen tinting, rather it is a poorly calibrated display. To fix the same, you can use a simple tool to make the screen balanced in terms of colors, which will result in the eradication of the above-mentioned tint. Or you can even try factory resetting your device. Still, if this does not fix the issue, try visiting the nearby service centre to fix the issue.
In simple words, No. Screen Tinting is something that is visible only in very rare circumstances. One needs to be in a low light environment and keep the device at just 15% brightness to even view screen tinting. If you are not a display nerd, you might not even be seeing this issue. That being said, if you are a display nerd, you might have a weird itch in your mind to fix the issue and we do not blame you for that. However, do note the issue is not as major as some people are pointing it out to be.
This concludes our article on screen tinting, what it is, how to fix it and more. We hope this has been helpful in understanding what screen tinting is and how to fix it.
Like snowdrops that appear with the spring, after the launch of new much-discussed phones, we get news about the first bugs. At least, the newly-released Nothing Phone (1) of Carl Pei’s new company is not ideal. Some buyers have already reported issues with the screen of the device. Particularly, there is a green tint display issue and dead pixels around the selfie camera.
If believe in complaints found by Android Authority, the green tint display issue does exist for the Indian models mainly/only. A user who bought his Nothing Phone 1 in India from Flipkart said that there was a green tint on the phone’s display. What’s more disappointing, the replacement unit has had the same problem.
Wow @Flipkart awesome job, within 2 consecutive days you managed to send two phones with defective screens. Even the replacement phone has tint issue.just another day for you guys
