Redmi K30: The problem with the yellowing in the holes of the screen and the official answer

There is a discussion on Chinese social networks that the area on the double hole turns yellow, and this has worried buyers of the device.

Πa few days ago, the Redmi the series was officially released Redmi K30. Screen hole design is a topic for discussion. THE Lu Weibing, General Manager of Redmi made an announcement about the design in the Redmi K30 series.

According to Lu Weibing, the LCD liquid crystal layer is only 3μm, very thin and very fragile. The liquid crystal layer is under two parallel layers of glass (CF colored film and TFT substrate). When the layers are parallel there is no yellowing but when the angle changes then the spot turns yellow. Obviously at the point of contact with the hole there is an angle that creates the phenomenon.

Moreover, the Lu Weibing Listed the two major advantages of the new generation Redmi K30 screen:

1. The thickness of the glass used has increased. Thickness has increased by 14% and increase structural strength.
2. The density of the support columns has increased. A large number of PS support columns have been added around the hole, ensuring the stability of the two glass structures around the hole.

As you can see, yellow is not a feature of mobile phones and it is not going to change.
