"You mean the LCD monitor?"

Zhang Rujing looked at Fang Chen and asked with some uncertainty.

Of course he knew about liquid crystals, or in other words, as a PhD in electrical engineering, if he didn't even know about liquid crystals, then his PhD would have been in vain.

The history of human discovery of liquid crystals is actually very early.

Nearly one hundred and fifty years ago, a German doctor discovered the special substance liquid crystal, and twenty years later, a German physicist first observed the phenomenon of liquid crystallization using a microscope.

Neither solid nor liquid.

Later, physicists and chemists of all generations continued to study liquid crystals. However, in the thirty years from 1930 to 1960, the research on liquid crystals entered a trough.

Scientists at the time concluded after research that although liquid crystallization was a special phenomenon, it was of no use to humans.

It can be said that in the past thirty years, research on liquid crystals has basically stagnated.

Later, with the development of the semiconductor industry, especially the rapid development of the patterning of transparent electrodes and the micro-machining technology of integrating liquid crystal and semiconductor circuits, in 1968, an American watch company invented the first LCD watch.

Three years later, a Swiss company developed mankind's first LCD display.

If we count the time, it is five years earlier than the release of Apple's first generation computer.

But here comes the question. Since there were already LCD monitors at that time, why didn't Jobs use LCD monitors when he decided to use Apple's first-generation computer monitor?

In fact, the reason is very simple. The cost of LCD monitors is too expensive, and compared with CRT monitors, the display effects of LCD monitors are not qualitatively superior.

Basically it can be judged as a tasteless product.

For a moment, Zhang Rujing was a little confused as to why Fang Chen took out this product, which had been proven by generations of scientists and the business community to be basically useless and had no major advantages.

And looking at Fang Chen's posture, it is obvious that he regards the LCD monitor as a substitute for the CRT monitor.

But is it possible?

Zhang Rujing felt that he was viewing this matter with 80% suspicion.

And this is what Fang Chen said. If someone else said this, he wouldn't even have the remaining two points of trust.

"Dr. Zhang, you are not wrong. I do think that LCD monitors will replace CRT monitors in the future and become people's first or even only choice for desktop monitors!"

What Zhang Rujing never expected was that when looking at him, Fang Chen said with determination and confidence.

To be honest, if he hadn't had a PhD in electrical engineering and hadn't been working hard in the semiconductor industry for nearly thirty years, he would have been as confident as Fang Chen. He would have believed that LCD monitors could replace CRT monitors in the future.

Seeing Zhang Rujing's appearance, Fang Chen chuckled: "Dr. Zhang, in fact, many scientific researchers are currently studying how to produce LCD displays at a lower cost, especially Dongwa, which has become the world's leader in this area.

at the forefront.”

If it were in future generations, if you ask ten people whether LCD monitors are the first choice or even the only choice for computer monitors, nine and a half of them will answer in the affirmative.

Especially those born after 2000, there is no trace of the existence of CRT monitors in their lives.

For as long as they can remember, they have been exposed to LCD monitors, and they have never seen antique CRT monitors.

So for Fang Chen, LCD monitors replacing CRT monitors will definitely not be a question, but an affirmation!

"In fact, compared to CRT monitors, LCD monitors still have some advantages, especially for ordinary users. Compared with its shortcomings, the advantages of LCD monitors are more tolerable and acceptable to ordinary users," Fang Chen said.

.

Zhang Rujing thought for a moment and nodded slightly.

Although he didn't quite agree with Fang Chen's previous judgment, he still agreed with what he said now.

LCD monitors do have many advantages over CRT monitors.

For example, the body is thin and saves space. Compared with the relatively bulky CRT monitor, the LCD monitor only takes one-third of the space of the former, saves power and does not generate high temperatures. It is a low-power product and can do more than CRT monitors.

Not getting hot at all.

There is no radiation, which is good for your health. Because the LCD uses a semiconductor switch arranged on each pixel to form various images, and then hits the screen through the backlight, it can be completely radiation-free.

In addition, the picture is soft and does not hurt the eyes. Unlike CRT technology, the LCD screen will not flicker, which can reduce the damage to the eyes caused by the display and make the eyes less likely to fatigue.

However, the shortcomings are also very obvious, such as the small visual deflection angle of the LCD and the tendency to produce image tailing.

This is because the field frequency of the LCD usually does not exceed 60HZ.

Moreover, the brightness and contrast of LCD monitors are not very good, the problem of dead pixels is very serious, and the rate of defective products is high. If you are not careful, you may produce a large number of defective products. This is why the price of LCD monitors remains high, and they can only be used in experiments.

One of the important reasons for staying indoors.

Moreover, after scientific research and tracking, it was found that the lifespan of LCD monitors is too short. They are usually scrapped in about five years, which is only one-quarter to one-sixth of the lifespan of CRT monitors.

Sometimes, just because it is laid flat, it will be scrapped.

Because it is placed flat, liquid will enter the gap due to gravity.

It is also very fragile, and even a slight bump will cause it to be scrapped.

In addition, LCD monitors have a very significant feature. When the resolution is lower than the default resolution of the monitor, the blurred picture will be very obvious. When the resolution is greater than the default resolution of the monitor, the colors in details will be distorted.

Of course, the most important reason is that LCD monitors are too expensive and not suitable for mass production. No consumers will pay for such a flashy thing.

It is precisely because of the above reasons that both the academic and business circles previously thought that LCD monitors were suitable for use in laboratories as a display of results.

As if he was afraid that Fang Chen didn't quite understand the advantages and disadvantages of LCD monitors, Zhang Rujing specially introduced them to Fang Chen in detail.

"Dr. Zhang, I know everything you said, but I want to ask you, how big do you think a CRT monitor over 30 inches will be?" Fang Chen suddenly asked.

"A thirty-inch CRT monitor? That probably weighs at least one hundred and forty or fifty pounds! This is really crazy. No one would want to do this."

Zhang Rujing couldn't help but take a breath. He really couldn't imagine that someone would put a 140-50-pound behemoth on the computer table.

"What if we go further? Forty-two inches, or fifty-five inches, or even a hundred inches?" Gu

Fang Chen held the table with his hands and poked his head towards Zhang Rujing. The corners of his mouth were slightly raised, with a strange expression, just like the evil ghost crawling out of the TV just now.

"No way! If it were really 100 inches long, the floor would be crushed!"

Not sure whether he was frightened by Fang Chen's appearance or by what Fang Chen said, Zhang Rujing said with a horrified expression.

"There will be! Dr. Zhang, in fact, you have overlooked one point. People's pursuit of large display devices is eternal. No matter how big it is, they will not think it is big."

"This has actually been proven by the development of televisions and CRT monitors!"

“When the first generation of Apple computers was released, it used a 12-inch monitor, and now the latest generation of Apple computers has a 17-inch monitor, and during this period, Apple has also released several models, 20-inch and 21-inch super large ones.

monitor."

"Although the hardware and software support is not good, coupled with the CRT monitor of this size, it is simply a disaster. Each unit weighs more than 30 kilograms, so the sales volume is not very good, but it is still enough to prove that people are interested in large monitors.

The desire for screen displays is a very important breakthrough direction for display companies in the future."

"As for the TV, let alone it. There is a high probability that no one wants to see that the floor needs to be reinforced just to install a TV."

When he thought of the 100-inch CRT monitor smashing through the floor, Fang Chen couldn't help but smile inexplicably.

After all, you need to know that although one hundred inches is only five times that of twenty inches in terms of diagonal size, if calculated in terms of surface area, one hundred inches is equivalent to 22 twenty inches.

So a 20-inch monitor already weighs 60 kilograms, and a 100-inch TV weighs more than 1,300 kilograms. This weight can really crush the floor when it is pressed against it.

Although a 100-inch LCD monitor is still huge and often requires a crane to move it from the balcony, its actual weight is only 240 to 50 kilograms, which is really small compared to a CRT TV.

Of course, that's what he calculated, but in fact, it is impossible for any company to be willing or able to produce such a large CRT picture tube, let alone a television.

If he remembered correctly, the largest CRT TV in the previous life was probably Sony's 45-inch super large color TV.

In fact, in the final analysis, the biggest reason for promoting the development of LCD screens is that people's demand for large-screen devices cannot be met.

This is actually more obvious on televisions.

In the 1980s, everyone generally watched 12- to 14-inch TV sets, but by the 1990s, TV sets had basically evolved to 20-inch or above.

By the turn of the millennium, various 30-inch large color TVs had appeared.

Later, larger-sized CRT monitors would definitely not be produced, so we would have to deal with LCD TVs.

At the beginning, 42-inch LCD TVs were already considered large, but in the next few years, 55-inch, 65-inch, and 75-inch TVs have gradually become popular.

That is to say, those 98-inch and 102-inch ones can still be called Big Macs, but they are slowly starting to enter the homes of ordinary people.

Fang Chen feels that in a few years, he may have one hundred and twenty inches.

Zhang Rujing fell into silence and did not speak for a long time.

After all, the size of both televisions and monitors has been getting larger over the years. This is absolutely an indisputable fact.

The size of the CRT picture tube is really too big. Maybe a little more than 20 inches, less than 30 inches, and over 100 pounds, everyone can accept it, but what if it is heavier?

I'm afraid it's just like what Fang Chen said, it's going to break through the floor.

At this time, it is not the advantages and disadvantages of LCD monitors and TVs, but the needs of users that force companies to develop larger LCD monitors.

And as for industrial products, once they are mass-produced, the price will indeed drop rapidly.

For example, with Qingtian Computer, tens of thousands of people have been working on it for more than two years, and the investment spent on it is astronomical.

If only one Qingtian computer is produced at this time, the cost of this Qingtian computer will be at least 20 billion.

But once it is mass-produced and one million units are produced, the average R&D cost will only cost 2,000 yuan per unit, which is much easier to accept.

And the sales of TV sets and monitors are more than a million units?
