"Well, it's a pity that the screen is a little too small..."

Although Catherine has promised to sponsor a supercomputer for Green Soul, this will have to wait until next year. The next-generation supercomputer is called "Blade" and uses blade servers. It is the latest masterpiece...

Seymour Clay, who is doing the final public relations, promises to get the official product before October, and by that time, Catherine will be able to promote the new product. Just in time, Green Soul can be used as an advertisement for herself.

But Catherine didn't care about that now.

Catherine is actually looking at her own Fed screen right now.

9.7 inches, resolution 640*480.

It is only two centimeters thick, which is very thick compared to future ultra-thin tablets, but for current technology, this is a very eye-catching new technology.

First, all fed technologies require the assembly of a front plate (anode) and a back plate (cathode or electron source) as well as side walls, isolators and suction devices. The anode and cathode plates are first fabricated separately and then assembled together with other components

, then seal it with glass powder or other new materials, and finally evacuate. This is the carbon nanotube-based fed assembly process.

Secondly, because electron acceleration requires a vacuum to avoid corona or plasma discharge, the mechanical structure of the fed is composed of a sealed glass envelope that is evacuated to create the vacuum required to accelerate the electron beam. Depending on the display size and glass wall thickness, isolation is usually required

isolator to protect the glass wall from damage from atmospheric pressure. The isolator must also be able to withstand high voltage gradients and be transparent to the user in normal operating conditions.

The current technology has just begun to appear and is not reliable. For example, in the 21st century, a 36-inch SED only needed 20 rib-shaped isolators to maintain a 1.7mm thick vacuum gap, but Catherine cannot do that here.

All FED technologies, including SEDs, require some form of getter technology to maintain the required vacuum within the glass envelope after the display has been evacuated and sealed.

So, in order to achieve this state, and because electronic components are lagging behind the 21st century, being able to achieve this 20mm thickness is already very remarkable.

"In the future, we will not use the original CRT monitor, but are we going to use this Fed screen?"

Elsa asked.

If it was a choice between LCD and CRT, Catherine would definitely choose CRT. As a gamer, the smear on the LCD screen can really make people blind...

"Of course, digitalization is an inevitable choice in our history. The current CRT can only use analog output, but in the future, digital output will definitely be the best choice - although analog output is very good in an ideal environment, in reality it is

In other words, digital display with high fidelity is the best.”

Catherine didn't say anything about interfaces and standards such as dvi and hdmi, because Elsa probably wouldn't understand them.

"But this screen is good for playing games. As long as the screen is larger, it will be very comfortable to use."

Catherine said again.

"Yeah?"

Elsa looked at the screen, as if she wanted to see the difference with the crt.

After a long while, Elsa muttered: "It seems to be sharper than CRT..."

Catherine shrugged.

For Catherine, what she compares is not the current CRT at all, but the LCD that shined in the future.

The color gamut of fed and crt are similar. The color gamut of both refers to the color gamut of phosphor, while the color gamut of LCD (liquid crystal) refers to the color gamut of backlight (transmitted light source). The former is an active display

Like (electron bombardment of phosphor directly emits light), the latter is passive development (backlight transmission, similar to viewing a reversal film with a film viewer).

From a principle point of view, active imaging is the most streamlined imaging method, eliminating the chromatic interference of transmitted light sources and diffuse reflection materials. Therefore, chromaticity and grayscale errors are smaller. Laser retinal imaging in active imaging will be the future

development goals.

Therefore, although many CRTs only have a color gamut of 72%, they can kill those LCD screens that claim a color gamut of 120%.

In Catherine's view, whether it is LCD, plasma, OLED and other display devices, due to the inherent limitations of light source characteristics, they can only be regarded as transitional products.

Catherine made a big leap forward, directly entering a more futuristic era and developing the fed screen.

Because of the early appearance of carbon nanotubes, this technology has also entered application early, and the fed screen using new technology is better than the original one.

"But computers in the future should indeed pay more attention to the development of graphics..."

Today's computers can already use 16-bit color. Intel and Thunder Labs have decided to give the next generation of computers the performance to display 24-bit true color. At that time, the business of using computers for image processing will definitely develop.

rise, and the development of images requires even more attention.

"In any case, the development of computers is the core..."

Catherine still regards computers as the core goal of her development.

Not only the hardware aspect, but also the software aspect needs to be worked hard.

This is like if someone looks at the same picture using an Apple computer and a Microsoft computer in the future, they will find that the colors are slightly different, because the gamma values ​​and colors of both sides are different.

If you really want the original color to appear in the picture, you can only use Starscream, a sharp weapon.

In addition, there is a color gamut.

The color gamut is the range of colors that the screen can display. Usually people think that the wider the color gamut, the better the screen, but in fact, this is not the case at all. If you want to see photos, videos or videos with accurate color reproduction on the screen

For other content, the color gamut of this screen must match the standard color gamut (srg.) used when producing such content.

——No matter how wide the color gamut is, the screen cannot display colors that are not in the original content. It will only over-render and distort the colors in the original content.

A narrow color gamut screen cannot display all the colors in the original content, but if the screen color gamut is too wide, it will display oversaturated and overly bright colors. This is why the display effect of a screen with a slightly narrower color gamut is better than a screen with an overly wide color gamut.

wide screen.

In the 21st century, the color gamut of most LCD screens is slightly smaller than the standard color gamut. In contrast, the color gamut of most OLED screens is larger than the standard color gamut, so OLED screens look very gorgeous.

, one of the big reasons is because of this.

"We should also set a standard for the color of monitors..."

For the time being, fed screens can only be manufactured by ourselves. Although carbon nanotubes are easy to manufacture, the only company that can screen out suitable carbon nanotubes is Catherine.

And now, the development of LCD screens is also advancing by leaps and bounds - Catherine guessed that this is probably caused by the changes caused by the current historical influence.

So Catherine believes that in the future, it may be LCD vs fed and sed screens.

LCD is relatively cheap and equally thin and light, which is its huge advantage.

Fed screens have developed by leaps and bounds in the past few years. This technological leadership and Fed's powerful ability to restore colors are Fed's advantages.

But for fed screens, the price is always a flaw.

"You can customize a corporate standard. Isn't this your favorite thing, Kate?"

Elsa suggested.

"Well, this is a good idea. Well, our next generation will be 24-bit color and 32-bit color. The trendy concept of 16 million colors can be used to block other products from the door..."

The so-called 16 million color display is just the maximum number of combinations of the three primary colors of red, green and blue. Although it is a 24-bit true color, this is actually an artificial definition.

To generate so many combinations, each color needs 256 levels of brightness, which requires eight digits when converted into binary. Each of the three primary colors requires eight digits, which add up to 24 bits. This is the so-called "24-bit color", but

It is not impossible to use 512 levels of brightness or the like.

Some mobile phones in later generations mostly use 260,000 colors, which are even more popular than 16 million color screens. This is because some lower-end screens can only produce 64 levels of brightness. That is, each color has 6 digits, and three colors plus

It is an 18-bit number. This is the so-called 18-bit color, which can produce up to 262144 colors.

The number of colors that can be produced by 64 levels of brightness is so small that it will cause obvious discontinuous color bands on pictures with smooth color transitions (such as the sky and faces). This phenomenon is called false contours. And commonly used compensation methods

There are two methods: the first is spatial dithering, which uses several adjacent pixels to produce transition colors, but this method will reduce the sharpness of the image; the second method is time-lag dithering, which uses rapid transformation

The color of a certain pixel is used to produce a transition color. The disadvantage of this method is that it may produce obvious flickering.

In the 16-color Age of Discovery, similar technologies were used. Through the jittering of the screen, technicians and artists used the 16-color Age of Discovery to create an 8-bit color feel and an extremely excellent picture.

"We use 24-bit true color as a measure. For a display that can print a single piece, our future enemy will be an ultra-thin display, so this aspect is necessary..."

The development of many technologies is very slow, not because the technology itself cannot develop well, but because the supporting technologies have not developed, so they cannot keep up.

But it's different now.

Catherine has driven the development of many industries, and the development of many industries has in turn promoted some technologies that were originally stagnant, and some have been accelerated.

Just like an LCD screen.

General Electric is currently researching liquid crystals, and as far as Catherine knows, in the past, General Electric should have given up on liquid crystal research, but now, this is completely different.

The changing history has caused drastic changes. Many people have also noticed the technology and existence that were originally ignored, or changed the original development strategy. This series of changes has caused many variables.

Catherine knows that at this time, experience can no longer speak for itself. At this time, development should be based on the current situation, and the fact of being prepared for danger in times of peace cannot be easily changed.

"But such an expensive screen, Kate, do you think anyone can afford it?"

Elsa asked suspiciously.

Indeed, although the screen was manufactured, it was indeed unaffordable. Although Catherine launched a batch of new notebooks for Fangzhou University, this does not mean that this kind of notebooks can be promoted to the market - otherwise, the high cost

The price can be prohibitive.

"That's true. But we may have a way to bring our products to a better future... Well, for example, we can use it for Pip-Boy..."

Catherine narrowed her eyes.

The Pip-Boy is still using a CRT screen. In normal times, this screen is just fine. However, the fire control version used by tanks and aircraft has a slightly bigger problem, because the CRT screen is easily affected by the outside world.

Interference - Even if you put a mobile phone next to the screen, the picture on the screen will probably be distorted.

Based on this, Catherine made a wise decision: sell the screen to the Pentagon first!

Anyway, the research funding for this screen is almost entirely borne by the Pentagon.

After making the best use of the thing, Catherine felt that it would be fine if she could sell it back to the other party at a high price.

"But yield is still an issue, Kate."

Elsa said again.

"Output is not the problem, the problem is the market. How big the market is, how big the output will be. That's what the market and economy are all about."

To put it simply, what is "market economy" is actually very easy to understand.

The so-called market economy means that when there is demand, there are products. At the beginning, the products could not keep up with the demand. This was because supply exceeded demand and commodity prices were artificially high.

Then, other people saw that this thing was making money, and then they jumped in. At this time, there were more products than demand. This was oversupply, and at this time, the price of the product became tragic.

The supply exceeds the demand, and many people can no longer hold on. Then there are fewer people doing this, and then it gradually grows, and it reaches a state where the supply exceeds the demand again, and the cycle starts again, and the cycle starts again. That's what it is.

Among them, there is also a short-term balance between supply and demand, but the irony of the products that reach this state is that most of them are monopoly products...

Catherine is currently in a situation where demand exceeds supply, but Catherine is not worried. Because in this case, the price of her products can be very high, and she can also use the current technologies to do things.

The most important thing is that although there are many coveters next to Catherine, Catherine is the only one who masters the core technology, so Catherine does not have to worry about this situation of short supply being broken.

There are thousands of things to say, but in fact, thousands of words can be summed up in one sentence: The people in the Pentagon are stupid and have a lot of money, so they are easier to fool...

"Hmm, yes, we can also expand the use... Well, just in time, doesn't Badua have a satellite plan? I don't know how far his plan has been researched, but this global positioning system plan,

It might work..."

"Kate, what are you going to do?"

Elsa subconsciously felt that Catherine was doing something inappropriate.

"It's just a borrowing, and Elsa, don't you think we can have a positioning system that only belongs to us? Isn't this a very interesting thing?"

"..." Elsa looked at Catherine blankly.

This is the generation gap!

Catherine sighed.

Catherine compared it to the 21st century.

It's like, everyone is using GPS for navigation, but Catherine uses her own private satellite system for navigation - the latter is obviously more awesome than the former!

But it is obvious that Elsa feels at a loss about Catherine's "fascination".

Because Elsa is from this era, she doesn't understand the meaning of what Catherine just said.

This is something that people of this era absolutely don’t understand.

Catherine didn't say much, because it would be very troublesome to explain.

"Didn't I once suggest to Badua that he should develop a satellite map positioning system? By borrowing GPS, we can know where we are in real time, how we should get to our destination, and how we should know where we are.

The name of the place you want to go, etc..."

For Americans, this is particularly meaningful.

Because the United States is almost a country on highways, the reason why the development of railways in this country is seriously lagging behind is because the highway system in the United States is too developed. In such a country, highways and highway navigation obviously have a different meaning.

Extraordinary meaning.

"That means...we are going to make a Marauder's Map?"

Elsa finally understood.

Catherine was stunned for a moment, then understood.

The Marauder's Map comes from "Harry Potter". It is a real-time map that allows you to see where the people on the map are.

"That's it."

Catherine nodded.

"oh."

In this case, it will be easier to understand.

Elsa already understood what Catherine was talking about before - Catherine was planning to create a real-life version of the Marauder's Map.

"It just so happens that Badua's plan was once favored by the military. Although Badua's plan did not make further progress, for us, Badua's plan happened to be a good opportunity for us to make a breakthrough.

, we can use Baduwa’s plan to achieve our goals..."

This is definitely a plan that requires courage to spend money.

But Catherine doesn't think she should invest so much money anymore - although she regards money as dirt, if six to seven billion are thrown out in one go, Catherine will feel distressed!

At this time, Catherine said she didn't want to spend money on herself anymore.

So at this time, the Pentagon is obviously a big head that can provide money to help with its research.

"I'm contributing to America's future!"

Catherine praised herself without shame...

…

A lot of shit happened today...
