FY-01's Insanely Powerful Performance

At Hua Long Technology's Research and Development Department, inside a Sample Room.

Research and Development Manager Du Yu, materials engineer Zhai Zhigang, Project Manager Wang Wei, and Project Director Wu Feng were all present. Other than the four of them, there was no one else in the Sample Room.

"Damn! Damn! All I can say is, damn!"

Wang Wei exclaimed repeatedly, practically dancing with excitement.

"Fucking awesome—so fucking awesome, it's unbelievable! It's even more fucking awesome than King Material. If I hadn't seen it with my own eyes, I wouldn't have believed it even if you beat me to death. I've tested thousands, if not tens of thousands, of materials, and hundreds, if not thousands, of optical materials. This is the first time I've ever seen a material this fucking awesome!"

Materials engineer Zhai Zhigang wore a look of utter shock, national curses spilling nonstop from his mouth.

"Looking at this material's performance, I wouldn't have believed it either if I hadn't seen it with my own eyes."

Project Director Wu Feng also clicked his tongue in amazement. His eyes burned with intensity, as though he were gazing at a peerless beauty.

"Look at this material's performance. These were just taken out of the lab. Some underwent low-temperature testing at -40°C, some underwent high-temperature testing at 80°C, and some underwent repeated low- and high-temperature cycle shock tests. They all came out perfectly flat, without the slightest wrinkle or shrinkage. At this level of performance, it's completely on par with King Material."

Research and Development Manager Du Yu sighed in admiration as well. Pointing at the ten six-inch FY-01 sheets laid out on the table in front of them, his face was filled with astonishment.

Materials engineer Zhai Zhigang pointed at two other FY-01 sheets and added, "These two were put through the Double 85 Experiment: 85°C and 85% humidity. After one hundred hours, they still look bright as new, with absolutely no wrinkles, shrinkage, or deformation. What's even more impressive is that after testing, I found that this material's light utilization rate only dropped by one to two percentage points. That's practically negligible—essentially no loss at all."

"Now that's fucking awesome!"

Wang Wei and Wu Feng cried out in amazement almost simultaneously.

For a product, people often heard descriptions like "reliable" and "high quality," but few had any concrete idea what reliability or quality actually meant. More often, they simply said it was easy to use, sturdy, and durable.

For an optical film material, reliability specifically referred to changes in its performance under various harsh conditions. The smaller those changes were, the higher its reliability; the greater the changes, the poorer its reliability naturally became.

To be even more specific, it meant placing different types of optical film materials into environments with varying conditions and testing the changes in their actual performance data.

In the mobile phone industry, conditions such as powering on and using a phone at temperatures as low as -40°C or -30°C, or as high as 70°C or 80°C, were set according to the situations a phone might encounter in natural environments. For instance, temperatures of -30°C or -40°C were common in cold regions. In hot regions, although the natural environment might reach only around 50°C to 60°C at most, a phone's internal temperature rose much higher than the ambient temperature while it was powered on and in use.

Take phones designed to run hot, for example. Their surface temperatures could be too hot to touch, reaching at least 50°C to 60°C—and that was after a series of heat dissipation measures. One could imagine that their internal temperatures were easily seventy or eighty degrees at minimum.

Thermal expansion and contraction was a fundamental principle. Nothing in nature could escape this law.

At low temperatures, materials contracted. Once an optical film contracted, it meant deformation. Its light utilization rate would change and decrease, and the angles at which light was refracted and reflected would also shift. The result was that the emitted light would appear dimmer or uglier to the human eye. Consumers definitely could not accept that.

The same applied under high temperatures, except it was expansion rather than contraction.

Low-temperature conditions were somewhat better. After all, although the natural environment might be cold, the phone's own temperature rose after it was powered on and running, so the chances of problems occurring were generally not high.

The real difficulty lay in high temperatures. The vast majority of optical materials developed all kinds of problems under high-temperature conditions. Optical materials were film-based and inherently thin, with various material coatings applied to the film. This easily caused an issue: different materials had different properties, so their expansion ratios naturally differed as well. Either the film expanded while the coating did not, or the coating expanded while the film did not. Once the various forces between them stacked together, problems naturally arose.

As product project personnel—or product managers, one could say—Wang Wei and Wu Feng normally did not participate in product research and development. But through constant exposure, they had gained a solid understanding of the problems encountered during product development.

The two of them also knew optical materials fairly well. At present, domestic-brand optical materials could pass the 80°C test without defects, but anything above 80°C was difficult to sustain.

It could be said that 80°C was a hurdle.

If subjected purely to temperatures of 85°C or above, domestic-brand optical materials—every single one of them—would basically fail.

Only King Material from Eagle Country could pass!

Zhai Zhigang said that FY-01 had passed the Double 85 Experiment. That was an entire level above a simple 85°C test, because it involved not only a high temperature of 85°C, but also 85% humidity.

Humidity referred to the water vapor present in the air. Under natural conditions, it was generally around 45% ± 20%, which was when people felt most comfortable.

Water vapor saturation meant 100% humidity.

At 85% humidity, the air contained a considerable amount of water vapor, making the conditions extremely damp. This was exactly what severe humid weather in the south was like. Under such humidity, not only did people feel uncomfortable, electronic devices and all kinds of other products also felt "unwell." That was because water vapor was corrosive. Its corrosion was not fierce or rapid, but gradual—like dripping water wearing through stone or an iron pestle being ground into a needle—which made it all the more troublesome.

How did rheumatism develop? Why did rheumatic pain flare up whenever it rained?

Because there was too much water vapor. It was caused by dampness.

Even under both high heat and humidity, FY-01 remained unaffected. That was enough to show the material's powerful reliability. It was practically the perfect material every engineering and research and development worker dreamed of.

That was also why the two men praised it so highly.

Of course, Eagle Country's King Material was at this level as well. That was why, before FY-01 appeared, King Material had dominated the field for more than half a century, unrivaled. It relied on nothing but genuine strength. Even if you refused to accept it, you had no choice but to.

Just like now, Eagle Country was still No. 1. Its strength was unmatched. This was not about one kind of hegemony or another—it truly was No. 1 in technology, leading the world and standing alone at the top. At least for the next ten or twenty years, that would remain the case.

"...Other than that, I also conducted scratch and abrasion resistance tests on it. Its performance is in no way inferior to King Material. Each of the environmental reliability tests above has basically run for one hundred hours. In my opinion, there's no need to continue the experiments—it would be a complete waste of time. This material is absolutely beyond imagination. My recommendation is that if it has a price advantage, the company must bring it in."

Materials engineer Zhai Zhigang pointed at another FY-01 sheet placed at the very edge of the table before giving his final assessment.

"The experiments should still continue. It would be best to run them for 240 hours. No, I suggest running them for 1,000 hours, then having the lab issue a formal report. In my view, it isn't just suitable for mobile phone screens. It can also be applied to automobiles, medical equipment, electric meters, water meters, and other equipment requiring ultra-high reliability."

Research and Development Manager Du Yu rejected his proposal and gave his own opinion.
