After two days of intense practice, Jim finally memorized the skill as if it were in his muscles. Now as soon as his hand touches the mouse, he will subconsciously rub the mouse's wheel.

Of course, this kind of operation is also very demanding for the mouse, especially the lubrication of the middle scroll wheel.

So, where to buy such a good mouse?

Of course, it is the high-end competitive mouse of the Super Yu-Gi-Oh series recently launched by Wanhu.

Not only is the scroll wheel in the middle covered with a layer of rubber, which is silky smooth, but there is also a matte translucent material throughout, which can dimly reveal the light provided by the RGB light-emitting diode inside.

As for......

Why is this kind of light-emitting diode capable of emitting 16 million colors, only found on mice and keyboards produced by 10,000 households?

This has to mention the first-mover advantage of technology.

Many people who only scratch the surface of patent law will think that if a patent is registered, it is only valid for twenty years, and all the money must be made within twenty years.

Although this is true in theory, in practice, it is not at all the case.

Because technology is never isolated and not developing, on the contrary, technology happens to be constantly improving.

Just like Wanhu at the beginning, it had the technology of just a light-emitting diode.

To be honest, the application scenarios of light-emitting diodes at that time were very simple.

It seems that there is only the use of backlighting for the game handheld of Wanhu.

Otherwise, at most, it will turn the neon signs into LED signs.

And after that?

Wanhu not only turned the already small LED module into a smaller SMD module.

With such a miniaturized light-emitting diode, there is no longer a bracket sticking out of the forehead of the handheld like Wanhu's game handheld to illuminate the entire screen.

Instead, it can illuminate the entire screen by simply arranging it in the four directions of the up, down, left, and right sides of the handheld screen.

Of course, the first 10,000 handhelds that used the entire technology all have different degrees of light leakage.

After all, an LCD screen is like a piece of paper. It is inevitable that the paper will not be completely flat, and there will always be some slight fluctuations. These fluctuations may not be visible to the naked eye, but they are very noticeable when illuminated by the strong light of the LEDs.

However, this flaw in the assembly process, which will be said to be poor in the workmanship of the mobile phone more than ten years later, is almost not cared about by players in this era.

Because this is already a very amazing technology for them.

You know, the color screen of Nintendo's handheld is still in the era of no backlight.

In addition, the screen transparency of Nintendo's handheld is not high, and when it is exposed to direct sunlight, it is basically impossible to see anything on the screen.

Finally, at night, the children want to hide in the quilt and play secretly for a while, and they are very embarrassed to need the lighting of the flashlight.

This is one of the reasons why Nintendo's color handhelds, compared to the pure black and white screen of the game boy, are not as successful.

Because of technical limitations, color handhelds are too limited for the use of scenarios.

At the same time, Wanhu's handheld computer not only completed the color LCD, but also successfully developed the backlight of the color LCD.

In terms of display effect, it is not on a grade at all.

In addition to the SMD LED lights that can be used as screen backlights, the RGBLED that can be seen on the mouse and keyboard can change colors infinitely, which is another technological innovation of Wanhu.

The patent time for each of these technologies is calculated separately.

In other words, although in another ten years, in all countries where 10,000 households have registered LEDs, LEDs can be manufactured without the authorization of 10,000 households.

However, more high-end SMD and RGBLED still need the authorization of 10,000 households.

That is, if a company has determined a first-mover advantage in a certain area.

It can take advantage of this first-mover advantage and stay ahead of the curve.

And which country advocated and proposed this patent system in the first place?

It's the United Kingdom.

It was the country where the Industrial Revolution first took place.

While nominally to protect the motivation of patent developers, in reality it is not intended to protect the UK's first-mover advantage.

You must know that if a late-developing industrial country wants to develop its industry, it must go through a process of imitation and learning.

And imitation and learning are much easier than starting from scratch and starting from nothing.

Therefore, in order to maintain its advantage, the UK can only have a patent law. So that those who came later, even if they could make products of the same technology, could not sell them within the limits of the British Empire's own and colonial territory at that time.

Later industrial countries, such as France and Germany, after going through the early imitation and learning, finally pulled their technological strength to the level of the United Kingdom, and even slightly exceeded it in some fields.

They also began to raise the banner of patents.

It is a system that declares that the patent system is intended to protect the motivation of technology developers.

After that, unless it is a country or region that has a large number of high-quality people, or even has a high-quality population, and does not play with the patent system.

Through various methods, the technical strength can be improved to a big level.

The rest can only comply with the system formulated by the first-class countries, and their own R&D strength is insufficient to break through the patent barriers built by the first-class national enterprises.

So, these small countries may have a large land area, but they have very little advantage in terms of technology.

It can only become an economic colony that provides raw materials and consumption power for first-class developed countries.

In this way, the first-class developed countries do not even have to send troops and personnel to carry out real colonization.

As long as the restrictions are imposed from the perspective of technological development, so that those late-developing countries always maintain a generation gap with themselves, they can always lie down and make money.

As for real-life examples?

The countries in South America are just examples.

Argentina, once a developed country, did not have the capacity to produce its own industrial goods.

Almost all industrial goods are imported from abroad, and a bicycle that may cost less than 200 yuan in China can be worth 200 US dollars in Argentina.

Argentina's own industry is nothing more than animal husbandry.

Even the deep processing of livestock is not necessarily done by domestic companies.

Therefore, in just a few decades, Argentina has completed the transformation from a developed country to a developing country.

And this is just a microcosm of South America.

The United States is shearing wool while standing on the high ground and looking down on the backyard of South America.

Saying that they are stuck in the middle-income trap has gone terribly wrong.
