Vacuum plating machine. What is this? Some people say that China can not make a vacuum evaporation machine, can only be restricted by foreign countries? What is an OLED screen and how does it relate to the phone screens we use everyday?
Before understanding the vacuum evaporation machine, let's have a look at the OLED screen. OLED screens may not be familiar to you, but LCD screens are familiar to you. The LCD screen is our liquid crystal display screen, and the OLED screen is the latest kind of screen. It has another name, it is called the dream display 39bet-đua chó-game giải trí -đá gà-đá gà trực tuyến-đánh bài. Oled screens offer many advantages over LCDS: they can be lighter and thinner, they use less power, they have better picture quality, and they have the biggest advantage of self-lighting. All in all, OLED screens are the best choice for mobile phones right now, but they're not without their drawbacks. It's bad for your eyes, so if you stay up all night playing with your phone, don't buy it.
Why do OLED screens glow spontaneously? This is inseparable from evaporation. Arguably the most important part of the screen's fabrication, the red, green and blue pixels on an OLED screen emit their own light, thanks to a light-emitting material that is vaporized. So let's just say that OLED screens wouldn't exist without evaporation.
So how to vaporize? Evaporation in detail, called vacuum evaporation. It's a little bit complicated to explain, but we can break it down into these stages. The first stage is to vaporize the material into gaseous particles. In the second stage, gaseous particles are delivered to the substrate surface. Finally, when these gaseous particles adhere to the substrate surface, they gradually grow into a layer of film, which is the whole process of evaporation.
If it's really hard to understand, we can think of cooking, the bottom of the pot steam, we put our hands on it, after a while our hands are wet. This is similar to steaming. It sounds simple, but vacuum evaporation is still very difficult. The heating methods are divided into electron beam heating, resistance heating, laser heating and so on.
I believe that here, we for vacuum evaporation exactly what is the matter and the relationship between evaporation and OLED screen, should completely understand it? But vacuum evaporation machines have been dominated by a Japanese company called Canon Tokk. Because of the early development and catch up with the dividend of The Times, Canon Tokk mastered the core technology of vacuum evaporation machine and blocked it. Canon Tokk is currently the world's leading authority on vaporized OLED screens.
Samsung is no stranger to us, right? Samsung's lead in OL Ed screens is thanks to the company, which accounts for most of the world's OLED panel shipments. And because we do not have the support of vacuum evaporation machines, we have been unable to compete with Samsung. Because the production of vacuum evaporation machines is too difficult, the yield is very low, the value of a production reached 700 million yuan, and even the leading Japanese enterprise Canon Tokk, the number of production in a year is about ten, later although we got vacuum evaporation machines, it is difficult to meet the development needs. So we had to develop our own steaming machine.
Some people say that China will never be able to produce vacuum evaporation machines, only to be monopolized by Japan. Is this really the case? Xinyihua enterprise gave the best answer. In 2020, it produced Xinyihua G2 evaporation equipment.
In addition to this company, Hefei Ryder also has the ability to produce evaporation machines.
Therefore, in the field of vacuum evaporation machines, China has successfully broken the monopoly of Japanese enterprises. Some people say that breaking the monopoly is certainly a good thing, but when you can realize the monopoly, is real pride, friends think?
