Isn't it just to deal with the problem of what the materials obtained from the National Institute of Materials Science and Technology in Japan were used to deal with such problems?

Although some of these technologies and materials are still flawed because of the relationship that was severed by later investment, Li Yifan turned around and pointed out these key problems, and then threw a lot of money into Qian Dezhi and his research.

Before he asked Qian Dezhi how he had done, he actually asked about the technical difficulties that had not been solved, and whether they had been solved.

As long as it is solved, Li Yifan plans to apply for a patent, not only in China, but also in the United States, Europe, and Japan.

Anyway, now the United States and Europe do not produce LCD screens at all, and even if they do, they produce the most high-end kind, and they follow the same path as the Japanese, which is based on plasma technology.

Although they have done this LED technology, but now that plasma technology is rampant in the world, they do not pay much attention to this LED technology.

Take advantage of the time when they don't pay attention to it, and hit them with a time difference, so that when the time comes, when the LED LCD screen occupies the market, they want to use their patents to restrict themselves, and they also have countermeasures.

You have guns in your hands. We have it in our hands, too.

"Hmm. That's good. If you get it all done, that's easy. ”

Li Yifan said. However, Qian Dezhi presented him with another problem.

"Boss, this technical problem has been solved, but there is still production equipment, you see if you can get a batch for us, after all, the production capacity of our current production line, the limit is 400,000 units per year, but the market of this LCD screen is more than 100 million." It's a production line with millions of units. I don't think that's enough. ”

Qian Dezhi said to Li Yifan, but when Li Yifan heard this, he couldn't help frowning.

Big brother, when these production equipment are cabbage, is it so easy to do? If you pay back one mouth, it will cost more than 10 million, aren't you kidding?

However, he didn't think about this problem at the beginning, and now Qian Dezhi's income is not unreasonable, this LED LCD screen, once it is produced, it will be listed. That's destined to be a big fire.

And if you want to beat the plasma LCD screen, then you have to work on the capacity and price now.

Capacity has gone up. The cost can be reduced, so that you can rest assured to fight a price war with plasma, but if the cost can't come down, what advantages do you have there?

It is true that the technology has been overcome, but the problem of this production capacity is also very big!

More than 80% of the main cost of this LCD display is on the LCD panel, and the biggest technical difficulty of the LCD panel is mainly concentrated in the epicrystalline and electronic control panels.

And these two aspects are precisely the least good at in China.

At the beginning, Li Yifan stole a set of LED production equipment from the factory of Sharp in Japan, and in fact, there was a set of panel production equipment inside.

However, the production capacity of this set of equipment is only 400,000 units per year, after all, Sharp does not attach much importance to LED technology, they bet all on plasma technology, and this plasma technology has made a lot of money for them in just a few years, so this LED technology is a step-up for them.

Because the technology used in LED LCD panels and plasma LCD panels is completely different, there are not many companies in the world that can produce LCD panels.

Plasma technology is to fill two glass substrates with inert gas, and then stimulate the inert gas through guò electric current to image the inert gas to achieve the purpose of display.

The LED LCD panel is to pay attention to the middle of the two glass substrates, sandwich a thin layer of liquid crystal, and then change the voltage to let the liquid crystal flow imaging.

And the most difficult point in this is the production of liquid crystal chips, which is commonly known as epidetatum.

This is quite difficult, generally using chemical vapor deposition, molecular epicrystalline technology, such a technology, even after more than ten years, is also a high technology, there are few domestic companies can do it.

And now the reason why Li Yifan can do it is completely because of luck and the technical equipment obtained from Sharp.

But now the production capacity of this equipment is not enough, so he needs to use his brains to see if he can get some equipment from the Japanese.

But this is difficult for Li Yifan, and it is quite difficult.

After all, although Sharp doesn't look down on this LED technology now, it doesn't necessarily, and they are willing to sell such panel manufacturing technology.

Last time, they took advantage of Sharp's people to be too lax, so they were caught off guard, and if they wanted to use such a stealing method to solve it this time, I'm afraid it wouldn't be very good.

One is that these machines are bulky, and because of the high precision, you can't disassemble them and transport them away, and then come back to assemble them.

The second reason is that after the Japanese suffered a loss, they will definitely pay more attention to these equipment.

The first time they were able to steal, it was because the Japanese didn't pay much attention to it, and then there was an earthquake in the northeast, and then there was a SAS virus in Japan.

They were so overwhelmed that they really didn't have time to pay attention to the theft, so they were able to get their hands on it.

If I go to Japan again now, then the possibility of missing and getting caught will be quite high.

It seems that we have to work hard from other directions, Li Yifan pondered in his stomach.

"Well, I'll take care of this matter, you don't have to worry about it for now. You should hurry up and try production first. Then check the yield and the condition of those machinery and equipment. If it is qualified, we will produce as much as possible, accumulate more inventory, and wait until I get the corresponding equipment, and we will increase the production capacity. ”

Li Yifan said to Qian Dezhi that now they want to produce the first generation, which is also the lowest technology and cheapest TNLED LCD screen.

The technical characteristics of this screen have some flaws. This is destined to be a low-end product.

As a 6BIT panel, his angle is not enough, it can only reach 160 degrees, and the maximum actual display color is only 262114, which is far from the standard 16 million colors.

However, Li Yifan's own understanding of this aspect in later generations gave Qian Dezhi a simple proposal, that is, to pass a layer of compensation film and let this layer of compensation film. Through the guò vibration mode, the maximum scale of color restoration. This makes it possible to achieve a true color of 16.2M for visibility.

In fact, after a few years, this technology has been used on the street, and now it is a very clever solution.

Qian Dezhi and his team overcame this problem in just a few months, so that the technical perfection of the TN panel was quickly completed.

Now the TN panel they produce is very mature and reliable, although it is still the lowest level of LCD panels, and the response time is more than 8 milliseconds, but in this era, this is undoubtedly a very good LED LCD panel.

And the most important thing is that although this LCD panel seems to be cumbersome to produce, it is the cheapest of all LED LCD panels that became popular later.

And Samsung relied on this TN panel back then, completely defeating the plasma LCD panel.

The reason is very simple, that is, the cost of this panel in the past is low, so the price on the market is cheap enough.

You must know that although his color reproduction ability is not the strongest, and the angle is not the largest, even the response time is the slowest.

But another important point is that such a difference is actually indistinguishable in the eyes of ordinary people.

It's easy to ignore the past, and for most consumers who are unskilled in technology, people may not be willing to pay for your technology, even if it is said to be a mess, after all, it is difficult for everyone to tell the difference between good and bad technology with the naked eye.

But in terms of price, everyone is much more sensitive.

Your so-called very good LCD panel costs more than 10,000, and this panel that looks similar to your LCD panel is only more than 4,000, you say you sell that?

What's more, your LCD panel is so thick, and this LCD panel is so thin, just from the appearance, it is more advanced than your plasma.

What's more, this monitor also saves power.

It's cheap, it's lightweight, and it's not expensive, which do you think everyone will choose in the end?

All are destined to be LED liquid crystal displays, which is also the development process of liquid crystal displays in later generations.

And TN LCD panels, relying on the advantages of low price, quickly beat the expensive plasma LCD displays in the market.

However, Li Yifan, who is familiar with the development experience of LED LCD panels in later generations, is not like only producing the lowest-end TN LCD panels in the future, he also wants to produce more advanced MVA and PVA panels.

However, this requires more liquid crystal epicrystalline equipment, and this is exactly what he has to solve like a solution.

After chatting with Qian Dezhi again, it was time to eat, because it was really in the factory, Li Yifan didn't want to go back to the city, so he went directly to the company's canteen with Qian Dezhi.

The company's canteen is quite good, the staff in the canteen are villagers invited from nearby villages, and they used to make wedding banquets for rural people.

The food was very fragrant, Li Yifan ate a lot, and after eating, he went back to the office to chat with Qian Dezhi, and suddenly he remembered the Ma Yunfei that Qian Dezhi recommended to him before, why didn't he seem to see him this time? (To be continued......)
