At this time, the company was building a new factory, one for the assembly workshop to expand production, and another for the manufacture of mobile phone screens, and some equipment had already been purchased.

The technology of the mobile phone screen is very complex, the top glass is the cover glass, the main component of which is silicon dioxide, and the hardness of the glass in the Mohs hardness chart is 6.5, which plays a role in protecting the internal structure of the mobile phone.

The second layer is the touch sensor layer, which is equivalent to a computer keyboard and belongs to the input device. The third layer is the front panel, which is mainly used to install filters and generate images. The bottom layer is the backplane, which handles millions of thin-film transistors.

The four layers of the screen contain a high technical content, and the materials are basic, and it is very difficult to get them all.

This is also the reason why Hang Yu invested hundreds of millions of dollars as soon as he came, and he had to burn a lot of money to achieve self-research and self-production in a short period of time. Fortunately, Fu Yunze did not disappoint him, and at the same time developed a four-layer process, and made a good finished product.

But if you make it in the lab, it doesn't mean that it will be commercialized right away, and there is a big technology gap between the two. If you want to achieve mass production and achieve a sufficient pass rate, it may be more difficult than making this thing.

At present, the world's energy production of mobile phone screens, and in line with the current business needs, is mainly Samsung, Sony, Sharp, Panasonic, Toshiba these Japanese and Korean companies, before Hang Yu also purchased mobile phone screens from South Korea.

Fu Yunze's screen is still far from the technical level of Japan and South Korea.

Such a screen is not competitive even if it is mass-produced, and can only be used in low-end mobile phones.

Of course, Hang Yu has not been crazy enough to compare with Japan and South Korea after more than a year of research and development, and his goal is the low-end market. At the same time, Hang Yu also believes that if he continues to invest in research and development in the future, he will one day reach the world's top level.

"Synthetic sapphire is not a difficult thing to do, and we have made qualified sapphire glass panels. However, in order to meet the production requirements, it is not possible to use the previous technology, and we must create new synthetic processing technology. Fu Yunze said.

Hang Yu was very concerned about the situation in Yanjing, anyway, it was not far away, and he personally came to the technical branch here. The laboratory does not have the sense of technology as imagined, and the surface of the equipment looks very ordinary, but Hang Yu is confused when it comes to operation.

He just wanted to see how the technicians were doing and see for himself how their work was progressing.

"How long will it take?" asked Hang Yu.

"Because there is no mature technology on the market at present, we are at the forefront, we can only rely on our own exploration, it is estimated that the time will be longer, this year will definitely not be able to do, I recommend continuing to purchase Corning's protective glass." Anyway, this thing has little impact on our screen, and we don't have any profit from our own research and development, so let's take our time. Fu Yunze said.

The use of synthetic sapphire as protective glass was put forward by Hang Yu. Because sapphire protective glass, sooner or later will become a future application trend, the first to develop is conducive to occupying the market.

And synthetic sapphire is not difficult, the difficult thing is mass production and post-processing.

The benefits of sapphire glass are many, it is hard and not easy to scratch, and it can easily cope with general bumps. Sapphire is second only to diamond in hardness and has higher wear resistance than crystal glass.

Of course, sapphire glass also has disadvantages, first of all, this material is much more expensive and heavier than Corning's Gorilla Glass, the synthesis process is more polluting, and the manufacturing cost is much higher, in short, it is difficult to market.

However, thanks to the special situation in China, these problems can be solved by expensive materials and manufacturing costs. On the contrary, it is a pollution problem, and it will be more difficult to develop a better process.

"What about the display layer and the touch layer?" Hang Yu skipped the question of the protective glass.

"We have adopted the IPS screen technology launched by Hitachi, and the research and development progress is very fast, and we can put it into production by the end of the year. The touch layer has developed a capacitive screen according to your requirements, and I have a finished product here for you to try. Fu Yunze said.

Hang Yu took a disassembled cat phone with a newly made screen connected to it. After opening the game of cutting fruits, after playing for a while, Hang Yu felt that this feeling was still very good.

Not a professional, or particularly attentive, it's hard to tell how much difference this screen is from the one you've purchased.

can meet this requirement, Hang Yu is basically relieved.

"How. Fu Yunze asked.

"There was a slight surprise, but the impact was not great, and it was ready to be put on the market. Hang Yu said.

"Our R&D time is too short, and although we have invested a lot of human and financial resources, we still have a long way to go to reach the world's top level. In fact, it is not certain that it will be put on the market until the lamination of the display and touch screen has been completed and has been tested. If you can, it's best to give us some more time. Fu Yunze said sincerely.

"Wasn't this display developed by you?" asked Hang Yu.

"No, you just used a touch screen that we developed. Fu Yunze was a little embarrassed, he had burned nearly 200 million so far, and he didn't even have a screen.

Of course, Hang Yu was not satisfied, but seeing Fu Yunze's tired face, it was difficult to talk about him.

At this time, the Yanjing Technology Department has more than 200 hardware engineers alone, and its strength is very strong. Such a technical team is piled up with money, and Hang Yu has great expectations for them.

Those engineers, seeing Hang Yu, the young chairman, were a little nervous in curiosity.

"Try to try to put it into production on time, it's really not good, this year it's still procurement. Hang Yu said helplessly, it is not good for him to rush into production with immature mobile phone screens, so as not to have problems that affect the reputation of cats.

"We tried our best. Fu Yunze said.

"Pay attention to the combination of work and rest at work, especially at your age, I can't explain to Fu Lei if something happens. These engineers should be no worse than you, you just need to coordinate it, and leave it to them as much as you can. Hang Yu said.

The average age of these hardware engineers hired by Fu Yunze is only in their thirties, and many young scholars in their twenties and seventeens. However, although they are young, their technical level is first-class, and they may lack some work experience.

But under the leadership of Fu Yunze, everyone has been engaged in research and development for so long, and they have grown up to some extent. Age is a big advantage, and Hang Yu believes that after a few years of training, they will become the backbone.

"Don't worry, my body is still strong, and it's okay to work eight or nine hours a day. Fu Yunze said heartily, this is his dream state of work, although he is tired but very happy.
