Blooming America

The handheld screen is a key point of the handheld exhibition. In history, the reason why the handheld can be displayed has a lot to do with the screen. **

After the screen began to become colorful and dynamic, at this time, technology began to limit the handheld.

If Catherine were to make a handheld machine that can play "Class Mario" now, there is no problem at all, but there is no such a game screen now, and I am afraid the battery life is not enough.

Not only the handheld, this problem also exists on the Beep side.

Catherine's beep was prepared for the individual equipment of the American soldiers. These two factors are also an important key to restrict the beep.

The personal version of Bibizi should be a simplified version of pda, but the battery life and display problems are seriously plagued the exhibition of Bibizi, so for now, Bibizi only has cars, and there are three models. In it, two of them are used in tanks, which is not in harmony with Catherine's exhibition strategy!

If the problem with the screen was to be solved, Catherine finally set her sights on the Fed.

Fed appeared very early. The so-called field-shè electrode theory was first proposed by R. in 1928. However, it was in 1968 that the field-shè electrode element was developed with semiconductor process technology and the use of field-shè electronics as display technology was started. It was proposed by netdt in the year and later attracted subsequent researchers to invest in research.

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

Strictly speaking, sed is also a kind of Fed.

These two types of monitors are both netbsp; cRT TVs have been popular until the 21st century before being gradually replaced by LCD TVs. However, it is difficult for LCD TVs to truly restore color, 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 displays.

If there are no accidents, the application of the field shè electrode was not until the French-netg company exhibited a display product made of the field shè electrode technology at the 4th International Vacuum Microelectronics Conference in 1991, and the field shè electrode technology was real. Being noticed and attracting investment from Micron, Ricoh, Motorola, Samsung, Philips and other companies has also enabled Fed to join the ranks of many flat-panel display technologies.

In the application of the field display, there is a vacuum belt between the receiver electrode and the receiver electrode. Therefore, a high voltage must be introduced between the receiver electrode and the receiver electrode to generate an electric field, so that the electrons of the electric field strike the phosphor under the receiver electrode to produce light effects. The principle of this kind of light is similar to that of the cRT. Both electrons collide with the phosphor light in a vacuum. The difference is that the cRT uses a single electron gun to control the electron beam through the deflection rail. The scanning direction, and the Fed display has hundreds of thousands of active cold shès, so in terms of structure, Fed can achieve a space-saving effect than cRT. The second is the voltage part. The cRT needs a working voltage of about kV, while the yīn pole voltage of the Fed is about 1kV.

Before Catherine came here, this display had reached a voltage of only 12V.

For now, there are two main factors that limit the Fed exhibition, one is the Fed material, and the other is the control chip.

The net pole shè line tube, but on the Fed, there are hundreds of thousands of shè fields, which requires very high requirements for the chip-at least, it is difficult to control it now. The other issue of field shè device components is also very important. Catherine is now using micro-scale arrays.

Although the technology of shè display can be realized in theory, its array characteristics limit the display size. The main reason is that its structure contains a circular hole in each array unit, and the circular hole contains a metal cone. During the process, both lithography and evaporation technology will limit the size of the

After all, now is the age, and it is impossible to use carbon nanotubes as in the future.

Without carbon nanotubes, the size of the Fed would be very large

But maybe it can be used on handhelds?

Catherine's thoughts immediately came out.

In theory, Fed products can be lighter and thinner than plasma or LCD flat-panel TVs, and consume much more energy than plasma or liquid crystals. It also has the advantages of high brightness, high contrast, high resolution, high responsiveness and wide viewing angle of cRT TV. Clear images can be seen from any angle. There is no electromagnetic radiation and xshè line radiation of cRT, and the cost is also low. not tall.

The only thing to be solved now is the problem of controlling the chip.

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

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

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

Catherine's gaze was not limited to the current square LED screen.

After all, although Led's theory is simple, relatively speaking, it is not too difficult.

However, although the Led lamp is more power-efficient than the cRT, it is still an electric tiger in front of the Fed.

If you want to model it, cost and control are both problems. Especially the brightness of this kind of photodiode is very high. But Catherine decided to move on to the Fed screen.

There are no LCD screens in this era, and if Catherine's Fed and sed screens are expanded, they will not necessarily expand more slowly than LCD screens.

Carbon nanotube technology has only been used on Fed screens since 1991. In a few years, Fed has grown from a 5-inch screen to a 32-inch screen. It is now 1967. In this case, perhaps by the end of the decade, the world will begin to spread. The Fed's TV set!

For the panel problem, Catherine can only go with the flow. She can't force it. She can only tell these researchers that carbon nanotubes are a good material-on the other hand, it is the battery. This problem is still unsolved. .

Now, the most mainstream storage battery is lead storage battery.

Even Arrow landing on the moon was preparing to use this battery, but this battery was later replaced by a cadmium-nickel battery, but the lead-acid battery exhibition has been very prosperous. Until the 21st century, many cars still have this battery.

The nickel-cadmium battery is about to be born. For Catherine, this battery may be a good cantilever. Before the lithium battery technology matures, the nickel-cadmium battery has always existed as a notebook battery, so this kind of battery should be very good.

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

As for dry batteries, Catherine never considered it. Such batteries seem to be okay for use now-but historically, dry batteries have not been used as a power source for handheld computers for too long. They were later replaced, what, 3ds and the like. , All use lithium battery power.

"Okay! Let's show off the lithium battery!"

Catherine was the final decision.

Although lithium batteries are dangerous to use, lithium batteries used later are just "lithium-ion batteries".

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

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

The matter is so settled.

With the hot sale of handheld devices, Catherine’s company moved a bit, but with the launch of the new plant, Catherine basically no longer has to worry about production capacity. She can produce as many products based on market demand.

But at this moment, Sanders found Catherine.

"Sister Edson, I want 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.

"Led light screen--"

After all, I have been studying for so long and just abandoned it. Isn't it a pity?

and many more!

Catherine suddenly thought of something.

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

The brightness of the LED screen is very high. In Catherine's original world, such things generally appear on the street, and Catherine feels that this idea of ​​her own is very useful-use it on the street!

In Catherine's original world, such LED screens are very useful. For example, squares and railway stations often have a screen that is hundreds of inches large, and such equipment is often used in large-scale dance parties and grand programs.

It's totally feasible!

"We want to continue research!"

Catherine said immediately.

"Led lamp screen, we not only need to study immediately, we also have to put out the advertisement of Led lamp screen!"

After hearing Catherine's inexplicable thoughts again, this time Sanders was obedient, and he was going to wait for Catherine to clarify the matter, and then continue to speak by himself.

At this time, Catherine continued: "Our Led light screen is very bright. In this case, we can use this screen on the street and performances. Isn't it very good?"

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

One thing Catherine has always emphasized in the enterprise is cost, upside down and downside efficiency. The entire company pays great attention 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 is very helpful to enhance the image of the city, you said, is it very effective? What?"

Sanders’ eyes lit up: “Yes! Even we can install such a screen for the city for free at the beginning. In this way, once this product appears, everyone will realize the advantages of our product, and we will accept it. If you continue to promote it, it’s easier to do a lot--"

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

"Yes, yes!"

Catherine immediately thought of this good plan.

"Because the LED screen is huge, so even if the chip's xìng is not good enough, we can also trade quantity for quality——"

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

"This matter can be done slowly, don't worry, let's spread the news on the LED screen first, and then look at the external feedback-if everyone is not optimistic about this product-then forget it."

Catherine still has a guilty conscience. After all, she doesn't know much about such a large LED screen.

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

At the same time, Sanders also shared the news on the LED screen to the outside world.

Catherine was ready to take the second place, even if it started with a black and white screen, but Catherine really "can't afford to support" an "electric tiger" like a LED light screen.

Originally, Catherine also considered whether the Led lamp can be miniaturized and low-brightness, but such a thing is basically difficult to achieve. At least so far, the research of Led lamp has not made a little progress, but is controlling it. In terms of this, a breakthrough has been made. Although the screen cannot display a complete image like a cRT monitor, it has been able to get a blurry dynamic image. This is already a very good progress.

With this news, the entire aRk company did not feel anything unusual, they were still just immersed in their work.

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

Especially those Japanese manufacturers have held board meetings several times in succession!

Jing Shenda, the founder of Sony and the creator of the original "Trinitron" picture tube technology in the world, is also distraught at the moment.

Catherine's dazzling television TV-, just launched, it swept the entire TV market fiercely!

You know, in this world where most TVs are semi-circular, a rectangular, completely flat TV is introduced. Such an advanced game console, how powerful it should be!

Because of this, the strong advantages that Japanese manufacturers have had over the American TV market are gradually fading.

At this time, Motorola approached mén and started cooperating with Sony.

Jing Shenda immediately realized that this was an opportunity!

Originally, Sony was also developing its own commercial products, but when the dazzling TV appeared, they were surprised 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 at a lower cost-all of which have caused great troubles, and at this time, Motorola has taken a lot of money to send it. When mén came, Jing Shenda immediately made a plan to make this cooperation very beneficial to Sony!

But at this time, Apple actually announced that the LED screen was turned on? !

In fact, not only Jing Shenda, but also many other people think that Catherine's new products are aimed at the TV market.

After all, the product is not official, it just sends a message to the outside world, but the result is that the news is misleading.

In fact, the screen of Led is indeed better than netbsp; first, the energy consumption of Led is at least half that of cRT. Secondly, Led can be made very thin, while cRT is a veritable "big man". There is no way to compare. Finally, the brightness of the LED is much greater than that of the cRT, which is also the advantage of the LED.

With so many advantages, how can it not be possible for Led to replace cRT and become the standard for the new generation of TV sets?

If such a thing happens, then Sony is in danger!

Not only Sony, I am afraid that the entire Japanese TV industry is in danger. Once this product appears, their old and tattered TV will be completely thrown into the historical trash can!

Therefore, Jing Shenda quickly went to Akio Morita.

After the two discussed it ~www.wuxiaspot.com~ soon the board of directors was held, and then they began to contact other vendors.

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

To this news, aRk still has no response, whether it is for Catherine, Sanders or Olsen, there is no special response to this product.

Current cRT TV sets are all interlaced. In Catherine's view, the next step for cRT is to scan progressively, then achieve high-definition and so on.

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

As long as one can generate technological advantages over those manufacturers, how can the other's products compete with one's own products?

Therefore, no matter who it is, there is not much reaction to this product—in fact, they don’t even know that the other party is going to study Led TV.
