Chapter 231 Evaporation Machine

Nothing is perfect, it has its own advantages and disadvantages, even the LCD screen is the same, it has its own disadvantages, but also has its own advantages.

First of all, the first advantage of the LCD screen is that it is very cheap. You must know that we have used LCD screens for decades. After so many years of development, the LCD screen technology has been very mature, and all the places that can be optimized have been optimized. Yes, it can be said that the existing shortcomings are all caused by the LCD itself.

Because the technology is very mature, industrial production has already been realized, and the production cost is very low, which naturally leads to very cheap LCD screens.

In addition, the LCD screen will not appear stroboscopic phenomenon, and the LCD screen has a light-emitting panel, so the service life is relatively higher than that of the OLED screen.

In addition, compared with the OLED screen, if the LCD screen has the same resolution, the LCD screen will appear clearer, which is because of the high pixel density of the LCD screen.

Of course, OLED screens also have their own advantages. For example, OLED screens can display pure black, which is impossible for LCD screens;

In addition, due to its own structure, the OLED screen itself is thinner and more flexible than the LCD screen. It can be used to manufacture curved screens, and it can emit light locally, which saves power. That is, in the same working environment, OLED screens mobile phones work longer.

There is also support for fingerprint unlocking under the screen, and the response speed is relatively short.

What is response speed?
We already know that the pictures on the screen are actually composed of small pixels, and the dots on these pixels have a color, and this color is composed of three colors of red, blue and green according to a certain ratio. of.

The speed of synthesis here is the response speed.

If the response time is too long, there may be smearing. From the working principle, the corresponding speed of LCD is longer than that of OLED, which is actually the case.

On the OLED screen, there is basically no response speed, and it can be said that the desired color is formed in an instant.

A long time ago, in the past [-] years or so, the screen must have been dominated by LCD screens, but with the development of the times, the overall performance of OLED screens is higher than that of LCDs.

LCDs are gradually being replaced by OLED screens.

In the current form, the screens of low-end mobile phones use LCD screens, and most of the screens of mid-to-high-end mobile phones use OLED screens.

Although the price of OLED screens is a bit high now, this requires a process. I believe that as time goes by and the manufacturing process continues to improve, the price of OLED screens will gradually decrease.

When any new thing appears, it conforms to this principle. The price is high at the beginning, and then the price gradually decreases.

Because technology continues to mature.

Now there is a trend that OLED screens are gradually replacing LCD screens.

For LCD screens, Zhang Xingchen is not going to intervene, because in Zhang Xingchen's view, this is already a sunset industry. In his opinion, LCD screens will be eliminated sooner or later, but it is only a matter of time.

Zhang Xingchen didn't want to work hard on this kind of product with no future in sight.

Moreover, LCD technology is very mature, and now many companies are producing LCD screens, and Star Company will not make much profit even if it inserts it.

The current LCD industry has entered an era of low profits, and vicious competition relies on low prices.

So Zhang Xingchen mainly focused on the OLED screen.

Regarding the OLED screen, it can actually be divided into three parts. These three parts are packaging and testing, coating organic thin films, and manufacturing glass substrates.

Of these three steps, the coating organic film is the most critical, so Zhang Xingchen wants to enter the OLED screen, first of all he has to chew down the most difficult bone of the coating organic film.

In the process of coating organic thin films, an indispensable machine is needed, and this machine is an evaporation machine!
Coating organic thin films cannot be achieved without an evaporation machine.

This is the same as the role of the lithography machine in the process of manufacturing chips, and it is essential.

Xingchen Company can even manufacture lithography machines, let alone vapor deposition machines, so Xingchen Company cannot be troubled at all.

Based on the current situation in our country, the level of the vapor deposition machines produced is still relatively low, and the performance is not as good as that of foreign vapor deposition machines. The actual situation is similar to that of the previous lithography machines.

Basically, imports are needed to meet the requirements, and the purchase depends entirely on the other party's wink.

We go there with a lot of banknotes, and the other party may not be willing to sell it to us.

In terms of manufacturing vapor deposition machines, the island country is actually better, and the vapor deposition machines manufactured are three generations higher than ours...

The island country is basically in a state of monopoly. Specifically, it is monopolized by a company named Canon Tokki. Basically, the high-end evaporation machines on the market are produced by this company.

Moreover, the vapor deposition machines produced by Canon Tokki have been recognized by the world. The former Pingguo Company even announced that it would not cooperate with vapor deposition machine manufacturers that did not produce Canon Tokki.

From this side, we can all see the awesomeness of Canon Tokki.

Because Pingguo has very high requirements for its own mobile phone, Pingguo can be recognized so much, which shows that Canon Tokki still has certain uniqueness in manufacturing evaporation machines.

In fact, there is no direct business relationship between Canon Tokki and Pingguo, and there is no contract signed in private, nor is there any alliance. In order to meet their demands...

Because it is a monopoly, the price of the vapor deposition machine cannot be said to be cheap. One set costs about [-] million yuan...

And similar to lithography machines, you can't buy it with money, it depends on whether the other party is willing to sell it to you. Of course, if the other party is willing to sell it to you, then the one sold to you is definitely not the most advanced.

It may have been used, it may have been eliminated, and it may be problematic.

In a word, the other party is willing to sell it to us because the other party has already looked down upon it.

One thing that is more unexpected is the output, that is, how many evaporation machines can be produced each year. The number is absolutely difficult to guess, and it is even less than the lithography machine.

In the past, only four vapor deposition machines were produced each year, but now the situation has improved a little, and ten units can be produced each year.

But this is not much, this is for the entire world market.

If we want to buy an evaporation machine, if the other party wants to sell it to us, we will have to queue for several years before we can actually get it.

It can be said that the vapor deposition machine is the entry ticket to enter the manufacturing of screens. Only when the vapor deposition machine is settled, can we really enter the screen industry.
