On December 15, it was reported that today, Lu Weibing made a science popularization on Weibo in response to everyone's question about the yellowing of the hole digging screen, and by the way publicized a wave of hole digging screen scheme adopted by Redmi K30.

The following is the content of Lu Weibing's microblog:

First of all, the LCD liquid crystal layer is a very thin and fragile material with only 3 μ m. The liquid crystal layer is covered with two parallel layers of glass (CF color film and TFT substrate respectively). The two glasses are kept parallel in an ideal state. In theory, the liquid crystal will not turn yellow. Only when the parallel state of the two layers of glass is broken, the screen will turn yellow when the uniformity of the liquid crystal changes.

So in order to avoid the deformation of two layers of glass, the new generation of hole digging screen of Redmi K30 starts from two aspects:

1. Upgrade Thick Glass. The two layers of glass are strengthened, and the overall thickness is increased by 14% to increase the structural strength;

2. Increase the density of support column. A large number of PS support columns are added around the hole, and the density of the support columns is much higher than that of the ordinary screen, ensuring the stability of the two glass structures around the hole.

In fact, not only that, but also the low shrinkage polarizer, the upgrading of dispensing process, and so on. All of these have made the screen structure stable for a long time, which can almost be said to really solve the industry problem of yellowing of hole digging screens.
