My Galaxy Technology

Hualong Technology, R\u0026D Department, a sample room.

R\u0026D manager Du Yu, materials engineer Zhai Zhigang, project manager Wang Wei, and project director Wu Feng were clearly on the list. Apart from the four of them, there was no one else in the entire sample room.

Good guy! Good guy! All I can say is good guy!

Wang Wei's eyebrows were flying and he exclaimed a series of times.

It's awesome, it's so awesome, it's incredible! It's even more awesome than the King's material. If I hadn't seen it with my own eyes, I wouldn't believe it. I've tested tens of thousands of materials, if not tens of thousands. Now, there are hundreds if not thousands of optical materials. This is the first time I’ve seen such an awesome material!”

Materials engineer Zhai Zhigang looked shocked and kept talking about the quintessence of Chinese culture.

“Looking at the performance of this material, if I hadn’t seen it with my own eyes, I wouldn’t have believed it.”

Project Director Wu Feng was also amazed at this time, the light in his eyes was hot and powerful, as if he was looking at a peerless beauty.

Look at the performance of these materials. These are just taken out of the laboratory. Some have undergone low-temperature experiments of -40°C, some have undergone high-temperature experiments of 80°C, and some have undergone continuous low-temperature and high-temperature cycle shock experiments. It is very smooth when taken out, with no wrinkles or shrinkage at all. This performance is completely on the same level as the king material.

R\u0026D manager Du Yu also praised repeatedly. He pointed at the ten 6-inch FY-01 materials placed on the table in front of the four people and spoke in admiration, with a look of shock on his face.

Material engineer Zhai Zhigang pointed to the other two pieces of FY-01 material and added: There are two more pieces. I arranged to submit them to the double 85 experiment with a high temperature of 85°C and a humidity of 85%. It has been taken out for 100 hours and they are still as bright as new. , there is no wrinkle, shrinkage or deformation at all, and what’s even more amazing is that after testing, I found that the light utilization rate of this material only decreased by 1 to 2 percentage points, which is basically negligible, equivalent to no loss.”

This is awesome!

Wang Wei and Wu Feng even exclaimed in unison.

People often hear adjectives such as reliability and good quality for a product, but they rarely have any idea of ​​how reliable it is and how high quality it is. They often just say that it is easy to use, strong, and durable.

As for an optical film material, reliability refers to the changes in its own performance under various harsh environments. The smaller the change, the higher the reliability of the product. The greater the change, the reliability of the product. Naturally, the worse it gets.

To be more specific, it is to put different types of optical film materials into environments with different conditions to test the changes in specific performance data.

In the mobile phone industry, it is used when the temperature is as low as -40°C or -30°C, and when the temperature is as high as 70°C or 80°C. This is set based on the conditions a mobile phone will encounter when used under natural conditions. of. For example, in cold areas, temperatures of -30°C or -40°C are common; in hot areas, although the highest natural environment is only about 50-60°C, the internal temperature of the phone will be higher than that due to the power on and use. It is much higher in the natural environment.

For example, the surface temperature of mobile phones that are designed for fevers is very hot, at least 50-60°C, and this is after a series of heat dissipation technologies. You can imagine the temperature inside it, at least seventy or eighty degrees.

Thermal expansion and contraction are the basic principles, and nothing in nature can escape this law.

At low temperatures, materials will shrink. Once the optical film shrinks, it means deformation, the utilization rate of light will change and decrease, and the angle of light refraction and reflection will also change accordingly. The result is that the luminescence changes when viewed by the human eye. Dark or ugly. As a consumer, this is definitely unacceptable.

The same goes for the high-temperature state, but instead of shrinking, it expands.

The low-temperature state is better. After all, the natural environment is low, but the temperature of the phone itself will rise after it is turned on and running. Basically, the probability of problems is not high.

The difficulty lies in high temperature. Most optical materials will have various problems at high temperatures. Because optical materials are thin films, they are thin, and the films are coated with various material coatings. This can easily cause a problem, that is The properties of different materials are different, and the expansion ratios are naturally different. Either the film has expanded, but the material coating has not, or the material coating has expanded, but the film has not. When various forces are superimposed on each other, problems will naturally arise.

As product projects, or product managers, Wang Wei and Wu Feng usually do not participate in product research and development, but they are basically familiar with the problems encountered in product research and development.

Regarding optical materials, the two of them know quite clearly that the current domestic brands of optical materials can pass the test at 80°C without any defects, but they are unsustainable above 80°C.

It can be said that 80℃ is a hurdle.

If you simply invest in high temperatures of 85°C and above, any domestic brand of optical materials will basically die.

Only the King of Eagle Sauce materials can pass!

Zhai Zhigang said that he took FY-01 and passed the double 85 test, which is an order of magnitude higher than the simple 85°C test, because it is not only a high temperature of 85°C, but also an 85% humidity.

Humidity refers to the presence of water vapor in the air. Under natural conditions, it is generally around 45%±20%. At this time, people feel very comfortable.

The state of water vapor is 100% humidity.

The humidity is 85%, and the water vapor is quite abundant. It is very humid under this condition, as is the case with the severe return to the south in the south. Under this kind of humidity, not only people feel uncomfortable, but electronic equipment and other types of products also feel uncomfortable. Because water vapor is corrosive, this kind of corrosion is not violent and rapid, but the water droplets penetrate the stone and the iron pestle is ground into needles, which is even more uncomfortable.

Where does rheumatism come from, and why does rheumatism hurt when it rains?

It's just too much water vapor and humidity.

Despite the high temperature and humidity, the FY-01 material remains unaffected, which shows the strong reliability of this material. It is simply the perfect material that all R\u0026D project engineers dream of.

And this is why the two of them praised each other.

Of course, Yingjiang's king material is also at this level, so before FY-01, the king material dominated more than half of the world and was unparalleled. It did not rely on anything else but real strength. You have to accept it even if you don't want to.

Just like now, Yingjiang is still No. 1, with unparalleled strength. It is not about this hegemony or that. It is indeed the No. 1 technology, leading the world and unparalleled in the world, at least for the next ten or twenty years.

...In addition to these, I also conducted scratch resistance and anti-scratch tests on it. The performance is not inferior to that of King Material. The above environmental reliability test basically lasted 100 hours. According to my opinion , there is no need to continue the experiment, it is a waste of time. This material is absolutely beyond imagination, my suggestion is that if there is a price advantage, the company must import it.

Materials engineer Zhai Zhigang pointed to a piece of FY-01 material placed on the edge of the table and finally said.

The experiment still needs to be carried out. It is best to do it for 240 hours. No, I suggest it to be done for 1,000 hours. At that time, the laboratory will issue a formal report. In my opinion, it is not only suitable for mobile phone screens. , and can also be applied to ultra-high reliability equipment such as automobiles, medical equipment, electricity and water meters.”

R\u0026D manager Du Yu rejected his statement and gave his own opinion.
