Chen Yao drove the car to Shenmo Chemical Materials Company.

He stopped the car, pushed the door and got out of the car, and received a text message. Chen Yao took it out and took it out.

It was sent by Yunzi, and she said she was willing to accompany her home for the New Year.

Chen Yao smiled knowingly. Before going home for the New Year, he had to do something and speed up the development of mobile phone screens.

When making mobile phones, if you want to become popular in the fierce domestic market, you must make breakthroughs in screen technology.

The team is doing research, but it has encountered a big technical bottleneck and is difficult to break through. Chen Yao must participate at the critical moment.

Shenmo Chemical Materials Company sounds like the name of a novel. Chen Yao usually likes to read novels, so he gave the company this name.

This company is indeed worthy of this name. It has been established in less than a year and is already the largest photoresist manufacturer in China!

In the past, this key material for producing mobile phone chips was monopolized by Japanese companies. Chen Yao led the team to break the Japanese monopoly and take the core technology into his own hands.

At this speed, it is only a matter of time before Shenmo Chemical becomes the world's largest photoresist manufacturer.

But Chen Yao was not satisfied with this. In addition to photoresist, some key chemical raw materials must also be made by themselves. To be honest, the gap between China's raw material research and development and daily development is too big.

Take the glass on mobile phone screen for example. Most mobile phone manufacturers in the world use Gorilla Glass from Corning, the glass they make must have better hardness, strength and light transmittance.

This is not a simple production process problem. People are at the forefront of the world in research and development in materials science.

Chen Yao walked into the company, put on a mask, and went into the laboratory in a white laboratory suit.

Chemistry Laboratory.

Zhou Weiming, who is also wearing a mask, stood in front of a vacuum glass tube to observe the chemical reaction of the Ito material in a high temperature environment.

Ito material is needed for almost every mobile phone screen. It is located under the glass of the mobile phone panel to realize touch sensing.

Chen Yao stood beside him and asked, "How is it? Is there any progress?"

Zhou Weiming exhaled: "Yes, but progress is slow."

Mobile phone screens are really not something that ordinary companies can do well. Most mobile phone manufacturers purchase other suppliers.

But Chen Yao had to develop his own mobile phones.

This is a unimaginable difficulty.

At the beginning, Chen Yao gave a general direction. The current mobile phone market is developing towards the trend of folding screens, but there are still many problems with folding screens.

For example, it is expensive and difficult to accept by most consumers.

The screen will have creases, which not only affects the beauty, but also prone to failure, black screen, and splash screen.

It is easy to break. Because the folding screen is expensive, once the screen is broken, you can change the screen to a good phone.

Although there are many problems, it is a trend to make the mobile phone screen bigger and bigger. The palm is so big, not the Tathagata's magic palm. The screen must be a trend to fold when it is folded.

The fact that Samsung and other giants have not done well is the opportunity for the legendary company!

Don’t think that screen technology cannot surpass Samsung. Legend is a very magical company. Semiconductor photoresist, euv lithography machine, Legend can do it.

The problem is here. How should Legend make a folding screen? How to solve the pain points of the folding screen?

Chen Yao looked at the parameters on the monitor: "Do you and the team have any ideas?"

Zhou Weiming thought for a while and said, "We have thought about developing a brand new plastic instead of glass."

Glass is made of easily broken and difficult to fold. If you use plastic, it will be much better to resist falling.

But the problem is...

Plastics have more problems, such as wear resistance is not as good as glass. In the era of feature phones, you know that plastic screens like Nokia are used, and that plastic screens are prone to scratches.

The scratch problem is unacceptable to consumers.

Although the manufacturer can paste a tempered film to solve the scratch problem when it is produced, there are other disadvantages in the plastic screen...

For example, the light transmission effect is not as good as glass.

No matter what kind of plastic is, the light transmittance cannot be compared with glass, and it also has a texture, and the texture of plastic is not as good as glass.

If a brand new plastic is developed, it can combine the advantages of glass and plastic and remove their shortcomings, this is the most perfect.

But the problem is, this new type of plastic is not so easy to develop. This involves a basic scientific issue, which is huge and complex.

Zhou Weiming frowned and said, "We have no good solutions to the development of new materials."

Chen Yao nodded, as expected.

He picked up the screwdriver, took out the phone in front of him, and took out the screen of the phone.

There are many parts for the screen, but it is not difficult to summarize, and it is mainly divided into four layers.

The most surface of the mobile phone is the piece of glass you touch with your fingers. It is called cover glass. Its main component is silica, and its main function is to protect the internal structure of the screen.

Remove the cover glass on the surface and is the second layer, touch sensor layer.

Its function is mainly used to detect touch operations.

The touch sensing layer currently used is mainly coated with a layer of ito material using magnetron sputtering technology on glass.

Ito is the Oxide of Silver, because this material has better conductivity and light transmittance, and almost all screens use this material.

Chen Yao disassembled it layer by layer, and the third layer of the screen is the front panel, and a filter is installed to display the image.

The last layer is the backplane, which is used to handle countless thin film transistors.

If the screen is folded, the most important thing is the two layers above. In addition to the cover plate, the sensor layer below must also be flexible and bend.

But now the mainstream ito materials are very fragile and difficult to bend and fold.

Is there an alternative?

There is a answer.

Chen Yao looked at Zhou Weiming and asked: "Have the team started the research and development of nano silver wires?"

"Not yet." Zhou Weiming shook his head. He had no way to find the cover on the surface. How could he develop a more difficult nano silver wire?

Compared with the fragility of the ito material, the nano-silver wire has better flexibility and can be used as a curved screen or folded screen.

It is a metal material, but it is very, very small, with a length of only microns and a width of only nanometers, which is invisible to the naked eye.

Because of the nano characteristics, this metal has good light transmission.

In addition to nano silver wires, there is another material that can replace ito, that is, metal grids, but the production cost of metal grids is high and the light transmittance is not as good as nano silver wires.

Therefore, nano silver wires are crucial materials for folding screens, but this black technology material and the most cash-based technology are mastered by the United States.

Even in the United States, there are still many problems in the nano silver wires made, which are difficult to mass produce and are extremely costly.

Chen Yao made up his mind that the nano silver wire must be made by himself, and to do the best!
