After two days of high-intensity practice, Jim finally remembered this skill like a memory in his muscles. Now, as soon as his hand touches the mouse, he will subconsciously rub the mouse's roller.

Of course, this operation also requires a high level of mouse, especially the lubrication level of the intermediate roller.

So, where can I buy such a useful mouse?

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

Not only is the roller in the middle of this mouse covered with a layer of rubber, it is as smooth as silk, but there is also a frosted translucent material everywhere, which can vaguely reveal the light provided by the RGB light emitting diode inside.

As for...

Why is this kind of light-emitting diode that can emit 16 million colors only available on the mouse and keyboard produced by tens of thousands of households?

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

Many people who only know one basic understanding of patent law will believe that once a patent is registered, the validity period of the patent is only twenty years, and all the money must be earned within twenty years.

Although this is true in theory, it is not the case in actual operation.

Because technology has never been isolated and still, it is not developed. On the contrary, technology is constantly improving.

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

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

It seems that only the use of backlighting for Wanhu’s game consoles.

Otherwise, at most, the neon signs will become LED signs.

And what after this?

Wanhu not only transforms the already small LED module into a smaller patch module.

Such a small-sized light-emitting diode no longer needs to extend a bracket on the forehead of the handheld console like Wanhu’s gaming handheld console, to illuminate the entire screen.

Instead, just be arranged in the four directions of the handheld screen, up, down, left and right, to illuminate the entire screen.

Of course, Wanhu handheld machines that first used the entire technology had different degrees of light leakage.

After all, an LCD screen is like a piece of paper. The paper will inevitably not be completely flat, and there will always be some slight ups and downs. These ups and downs may not be visible to the naked eye, but when they are shining by the strong light of the LED, they will be very obvious.

However, after more than ten years, people would say that the assembly process of mobile phones is really poor, but almost no players care about it in this era.

Because this is already a very amazing technology for them.

You should know that the color screen of Nintendo handheld consoles is still in the era of no backlight.

In addition, the screen transparency of Nintendo handheld consoles is not high, so when they are exposed to direct sunlight, they can basically not see anything on the screen clearly.

But at night, the children wanted to hide in the bed and play secretly for a while, and they were very embarrassed to need the lighting of the flashlight.

This is also one of the reasons why Nintendo's color handheld console is not that successful compared to the game boy with pure black and white screens.

Due to technical limitations, colored handheld machines have too many restrictions on the use scenarios.

At the same time, Wanhu's handheld machine 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 the same level at all.

In addition to the patch LED light that can be used for screen backlighting, the RGBLED with incredible colors that can be seen on the mouse and keyboard is another technological innovation for Wanhu.

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

In other words, even in ten years, LEDs can be manufactured in all countries where ten thousand households have registered LEDs without authorization from ten thousand households.

However, more high-end patch and RGBLED still require authorization from tens of thousands of households.

In other words, if a company determines its first-mover advantage in a certain field.

It can take advantage of this first-mover advantage and continue to lead.

And which country promoted and recommended this patent system at the time?

It's Britain.

It is the earliest country where the Industrial Revolution occurred.

Although it is nominally intended to protect the enthusiasm of patent developers, it is actually not to protect the first-mover advantage of the UK.

You should know that if late-developed industrial countries want to develop industries, they must go through a process of imitation and learning.

Imitation and learning are always much simpler than starting from scratch or starting from nothing.

Therefore, in order to maintain its advantages, Britain could only establish patent laws, so that those late imitators, even if they could manufacture products of the same technology, could not be sold within the scope of the British Empire's own and colonial scope at that time.

After the early imitation learning, industrial countries such as France and Germany finally pulled their technical strength to the level with Britain, and even slightly exceeded in some areas.

They also began to raise the banner of patents.

It claims that the patent system is a system to protect the enthusiasm of technology R&D personnel.

After that, unless it is a country or region with a huge population of high-quality people, or a high-quality population, and does not use the patent system.

Through various methods, we can improve our technical strength to a big step.

The rest can only abide by the systems formulated by first-class countries, and their R&D capabilities are insufficient, so they cannot break through the patent barriers built by first-class national enterprises.

Therefore, these small countries may have a large land area, but have very small advantages in technology.

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

In this way, first-class developed countries do not even have to worry about sending troops and personnel to implement real colonization.

As long as you restrict it from the perspective of technological development and allow those latecomers to always maintain generation differences with themselves, you can always make money.

As for the actual example?

The country in South America is just an example.

Argentina, which was once a developed country, did not have the ability to produce industrial products on its own.

Almost all industrial products must be imported from abroad. A bicycle that may be sold for only 200 yuan in China can be worth 200 US dollars in Argentina.

The industry that Argentina owns is just animal husbandry.

Even the deep processing of animal husbandry is not necessarily completed by domestic companies.

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

And this is just a microcosm of South America.

While cutting wool, the United States stood on the commanding heights and looked down at the back garden of South America, the United States.

It has been said that they are trapped in the middle-income trap and there are big problems.
