The screen of handheld consoles is a key point in the development of handheld consoles. Historically, the development of handheld consoles has a lot to do with the screen.**

After the screen began to become colorful and dynamic, it was only then that technology began to impose restrictions on handheld consoles.

If Catherine were asked to make a handheld console that could play "Super Mario" now, there would be no problem at all, but there is no such game screen now, and I'm afraid the battery life is not enough.

It’s not just handheld consoles, this problem also exists on beep noodles.

Catherine's PiBi Xiaozi is intended to be an individual equipment for the American soldiers. These two factors are also an important key to limiting the BiBi Xiǎo.

The personal version of Bibi Xiaozi should be a simplified version of a pda. However, battery life issues and display problems have seriously troubled the development of Bibi Xiaozi. So for now, Bibi Xiaozi only has cars.

Moreover, two of the three models are used in tanks, which is completely inconsistent with Catherine's development strategy!

To solve the screen problem, Catherine finally turned her attention to the Fed.

Fed has appeared very early. The so-called field emission electrode theory was first proposed by R. in 1928. However, the field emission electrode components were actually developed using semiconductor process technology and the use of field emission electrons as display technology began.

It was proposed by dt in 1968, and subsequently attracted subsequent researchers to invest in research and development.

However, in this era, Fed has become Catherine's research project, and this concept has been proposed a long time ago. Currently, the company is jointly researching Fed with Stanford University.

Strictly speaking, sed is also a type of fed.

Both monitors are extensions of CRT monitors.

CRT TVs were popular until the 21st century, when they were gradually replaced by LCD TVs. However, it is difficult for LCD TVs to truly restore colors, so many people are very dissatisfied with LCD TVs - at least Catherine is one of them.

Therefore, Catherine has now begun to study fed and sed monitors.

If there are no accidents, the application of field emission electrodes did not begin until 1991, when the French company leti-cheng exhibited a finished display made using field emission electrode technology at the 4th International Vacuum Microelectronics Conference.

Electrode technology has really attracted attention and attracted investments from companies such as Micron, Ricoh, Motorola, Samsung, and Philips, which has also allowed the Fed to join the ranks of many flat-panel display technologies.

In the application of field emitting displays, there is a vacuum zone between the emitting and receiving electrodes. Therefore, high voltage must be introduced into the emitting and receiving electrodes to generate an electric field, so that the electric field stimulates the electrons to impact the phosphor under the receiving electrode, thereby generating

Luminous effect. This kind of luminescence principle is similar to that of a yinode wire tube (crt). Both electrons collide with the phosphor in a vacuum to emit light. The difference is that the crt uses a single electron gun to emit an electron beam through a deflection orbit.

Controls the direction of electron beam emission scanning, and the fed monitor has hundreds of thousands of active cold emitters, so in terms of structure, fed can achieve a space-saving effect than crt. Secondly, the voltage part, crt requires about 1530kv of work

voltage, and the Yin electrode voltage of the fed is about 1kv.

Before Catherine got here, this kind of display had reached the point where it only needed 12v.

For now, there are two main factors limiting the development of the fed. One is the material of the fed, and the other is the control chip.

The crt is a deflection electric field and a yin electrode wire tube, but on the fed, there are hundreds of thousands of emission fields, which requires very high requirements for the chip - at least, it is difficult to control the current sfc

Come. Another issue of field generator components is also very important. Catherine is now using micro-sized arrays.

Although it is theoretically possible to realize the technology of LED display, its array characteristics limit the size of the display. The main reason is that its structure contains a round hole on each array unit, and the round hole contains a metal cone.

During the production process, both photolithography and evaporation techniques will limit the size.

After all, this is the 1960s, and if you want to use carbon nanotubes as you will in the future - it's impossible.

Without carbon nanotubes, the size of fed would be very

But maybe it can be used on handheld consoles?

Catherine's thoughts immediately spread out.

Theoretically, Fed products can be thinner and lighter than plasma or LCD flat-panel TVs, and consume much more energy than plasma or LCD TVs. They also have the advantages of high brightness, high contrast, high resolution, high response speed and wide viewing angles of CRT TVs.

, clear images can be seen from any angle, there is no electromagnetic radiation and xshè line radiation of crt, and the cost is not high.

The only thing that needs to be solved now is the problem of the control chip.

If the resolution does not need to be too high, this problem may be easier to solve.

Moreover, at the beginning, you may not need the control circuit to be too complicated, or even just need black and white.

Although it is black and white, it should be better compared to the current LED light screen, right?

Catherine's eyes are not limited to the current square LED light screen.

After all, although the theory of LED is simple, it is relatively not too difficult.

However, although LED lights are more energy-efficient than CRTs, LEDs are still an electric tiger in front of the Fed.

But if you want to miniaturize, cost and control are all problems, especially since the brightness of this kind of light-emitting diode is very high, there are a lot of problems, but Catherine decided to continue studying the Fed screen.

There were no LCD screens in this era, and if Catherine's fed and sed screens developed, they would not necessarily develop slower than LCD screens.

In 1991, carbon nanotube technology began to be used in Fed screens. In 20 years, Fed screens have developed from 5-inch screens to 32-inch screens. Now it is 1967 and the next year, maybe in the 1990s,

By the end of the 2000s, fed TV sets will begin to become common in the world!

Regarding the panel problem, Catherine could only let nature take its course. She could not force this aspect. She could only tell these researchers that carbon nanotubes were a good material - but on the other hand, as for batteries, this problem was still unresolved.

.

Nowadays, the most mainstream battery is lead-acid battery.

Even the Apollo moon landings were going to use this kind of battery, but this kind of battery was later replaced by cadmium-nickel battery. However, the development of lead-acid battery has been very prosperous. Until the 21st century, many cars still have this kind of battery.

.

Nickel-cadmium batteries are about to be born. For Catherine, this battery may be a good cantilever. Before lithium battery technology matured, nickel-cadmium batteries had always existed as notebook batteries, so this battery should be very popular.

good.

Lithium batteries are the most ideal batteries, followed by nickel-cadmium batteries.

As for dry batteries, Catherine has never considered them. Such batteries seem to be fine for use now - but historically, dry batteries did not become the power source of handheld devices for a long time, and were later replaced by, what, 3ds and the like.

, all use lithium battery power.

"Okay! Let's develop lithium batteries!"

Catherine finally made the decision.

Although lithium batteries are very dangerous to use, the lithium batteries used later are only "lithium-ion batteries".

Moreover, it is impossible for Catherine to study this kind of battery herself - she has no idea about it!

Therefore, Catherine made a decision: to invest in nickel-cadmium batteries first, using this product as an intermediate product, and then develop lithium-ion batteries.

That's how things settled.

With the hot sales of handheld devices, Catherine's company xiǎoxiǎo has been shaken. However, with the new factory put into production, Catherine basically no longer has to worry about production capacity. She can produce as many products as the market demands.

But at this time, Sanders found Catherine.

"Miss Edson, I would like to ask, what should we do with our LED light display plan?"

The company's strategy has changed. The LED display screen, one of the original key strategies, seems to be no longer important. Catherine has once again set her sights on the Fed screen.

"As for the LED light screen——"

After all, it has been studied for so long, and then it is abandoned like this. Isn’t it a pity?

etc!

Catherine suddenly thought of something.

If you can't use it here, it doesn't mean that such a screen can't be used in other places!

The brightness of the LED light screen is very high. In Catherine's original world, such things generally appear on the streets, but Catherine feels that her idea is very useful - use it on the streets!

In Catherine's original world, such LED screens were widely used. For example, in places such as squares and train stations, there would often be a screen of several hundred inches, and they would often be used in large-scale theatrical dances and grand programs.

to such equipment.

It’s totally doable!

"We need to continue research!"

Catherine said immediately.

"As for the LED light screen, we not only need to study it immediately, but we also need to advertise the LED light screen!"

Hearing Catherine's inexplicable thoughts again, Sanders learned the lesson this time. He was ready to wait for Catherine to explain the matter clearly before continuing to speak.

Catherine continued at this time: "Our LED light screen is very bright. In this case, we can completely use this kind of screen in streets and performances. Isn't this great?"

Sanders thought for a moment, "In this case - wouldn't the cost be very high?"

One thing that Catherine has always emphasized in the company is cost, and the whole company attaches great importance to cost saving.

"Yes, but it depends on who our customers are. You said, if this is a large-scale municipal project, such a screen would be very helpful in improving the image of the city. Do you think it is very effective?

Woolen cloth?"

Sanders' eyes lit up: "Yes! We can even install such a screen for the city for free at the beginning. In this way, once this product appears and everyone realizes the advantages of our product, we will continue to

It will be much easier if we continue to promote it——"

Sanders is becoming more and more mature. Although he is still a young man in his twenties, his strategic vision has begun to become stronger.

"That's right!"

Catherine immediately thought of this good plan.

"Because the LED light screen is huge, even if the performance of the chip is not good enough, we can still trade quantity for quality——"

Yes, such a "face-saving project" is, to a certain extent, a project where "money is not an issue at all". Catherine feels that this plan is really feasible.

"This matter can be taken slowly. There is no need to rush. Let's spread the news about the LED light screen first, and then look at the feedback from the outside. If everyone is not optimistic about this product, then forget it."

Catherine still felt a little guilty. After all, she didn't know much about such a large LED light screen.

All in all, the original technical research team has not been disbanded, but is preparing to change the LED light screen from miniaturization to large-scale.

At the same time, Sanders also revealed the news about the LED light screen to the outside world.

Catherine was ready to settle for the next best thing, even if she started developing with a black and white screen, but she really couldn't afford the "electric tiger" of an LED light screen.

Originally, Catherine also considered whether LED lights could be miniaturized and low-brightness, but such a thing is basically difficult to achieve. At least so far, there has been no progress in the research of LED lights. Instead, it is controlling the

In terms of technology, breakthroughs have been made. Although it is still not possible to display a complete image on the screen like a CRT monitor, it is possible to obtain a blurred dynamic image. This is already a very good progress.

As soon as this news came out, the entire Ark company didn't feel anything unusual. They were still just immersed in their own work.

However, at this time, the outside world had already exploded.

Especially those Japanese manufacturers held several board meetings in succession!

Dai Ibuka, the founder of Sony and the developer of the "Trinitron" picture tube technology in the original world, was also very anxious at this moment.

Catherine's dazzling television, tv-go, has just come out and has taken the entire television market by storm!

You know, in this world where most TVs are semi-circular, it would be so powerful to launch a rectangular, completely flat TV and such an advanced game console!

Because of this, the strong advantage that Japanese manufacturers had in the U.S. TV market is gradually fading.

At this time, Motorola approached Men and began to cooperate with Sony.

Jing Shenda immediately realized that this was an opportunity!

Originally, Sony was also developing its own commercial products, but when Dazzle TV appeared, they were shocked to find that these products were completely ahead of them!

Not only that, their products are completely ahead of Sony, and they are more advanced than their products, and the cost is lower - all of this makes Ibuka troubled, and at this time, Motorola comes to the rescue.

When the news came, Ibuka immediately made a plan to make this cooperation very beneficial to Sony!

But just at this moment, Apple actually announced the development of LED light screens?!

In fact, not only Ibuka, but also many other people believe that Catherine's new product is aimed at the TV market.

After all, the product is not official yet, it is just a message to the outside world, but the result is that this message is misunderstood.

In fact, LED screens do have advantages over CRT screens.

First of all, LED saves at least half of the energy consumption than CRT. Secondly, LED can be made very thin, but CRT is a veritable "big guy". There is no way to compare the two aspects. Finally, the brightness of LED is far greater than

crt, this is also the advantage of led.

Since there are so many advantages, why can't LED replace CRT and become the standard for the new generation of TV sets?

If something like this happens, Sony will be in danger!

Not only Sony, I'm afraid the entire Japanese TV industry is in danger. Once this kind of product appears, their old, shabby TVs will be completely thrown into the trash can of history!

Therefore, Ibuka quickly went to find Akio Morita.

After some discussion, the two quickly held a board meeting and began to contact other manufacturers.

So, on September 1st, Sony, Panasonic, and Toshiba began to announce the development of a "new generation of televisions," but they did not reveal the specific details of what it was.

Ark still had no reaction to this news. Neither Catherine nor Sanders nor Olson had any special reaction to this product.

Today's CRT TVs are all interlaced. In Catherine's opinion, the next step for CRT is to scan progressively and then achieve high definition and so on.

The future has been planned, what else can the other party do?

As long as you can create technological advantages over those manufacturers, how can the other party's products be able to compete with your own products?

Therefore, no matter who it is, there is no big reaction to this product - in fact, they have no idea that the other party is planning to research LED TVs.
