The figure of Ningguang 3.1 lithography machine appeared in Xia Xueyi's sight through the glass of the visiting passage, and he couldn't help but hold his breath. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

It resembles a giant filing cabinet, with two rows of dark glass doors on top and bottom, and a CRT monitor placed inside the glass door on the top right.

At this time, the display is displaying some data on the operation of the equipment, and the values are changing slowly and not very much.

On the surface, it's hard to believe that this humble piece of equipment is the most difficult lithography machine in the electronics industry to make.

In fact, what Xia Xueyi saw was not originally a lithography machine used for the front process, but a packaging lithography machine for the back process.

The lithography machine has a front and back road, and the lithography machine in the front process has a higher technical content and higher requirements for production conditions, mainly used to process the internal circuit of the chip. The back-end lithography machine is used for packaging, processing the external circuit of the chip, the shell, the pins and other parts with slightly lower processing requirements.

As the progress bar on the display ended, the lithography machine made a beeping sound, and soon a staff rushed over to take out the LED chip that had been packaged from the packaging lithography machine.

After the lithography part, the subsequent processing process is relatively fast. After etching, circuit deposition, chip cutting, external housing packaging and other processes, the LED lighting circuits are considered to be produced.

It didn't take long for the world's first batch of industrially produced LED light-emitting chips to be delivered to Hu Wenhai and Xia Xueyi.

"This is the LED light-emitting chip?" Xia Xueyi excitedly turned over the inconspicuous chip in her hand and studied it carefully.

Different from the packaging of ordinary chips, the packaging of LED chips uses transparent resin, which directly exposes the gallium nitride circuit of the chip to the naked eye. At this time, what Xia Xueyi is most concerned about is how much of a role the small chip between these square inches is.

Although the relevant data of LED Xia Xueyi has already memorized the rolling melon, and its core advantages and luminous principles are also well understood, but after all, hearing is false, seeing is believing. Whether LED lighting can replace other light sources on the market today is not something that can be described only by data.

Hu Wenhai nodded and explained: "Its substrate is monocrystalline silicon, the luminescent material gallium nitride, and the excitation material is yttrium aluminum garnet. The blue light emitted by gallium nitride partially excites yttrium aluminum garnet to produce yellow light, and what the human eye observes is an approximate white light produced by a mixture of blue and yellow light. ”

"LEDs emit a lot of brightness, but they consume 25 lumens per watt, which is nearly twice as efficient as incandescent lamps and almost the same as tungsten halogen lamps. But that's not the limit of LED light, we have achieved a luminous efficiency of 120 lumens per watt in our lab, but we haven't put it into production yet. ”

"120 lumens?" Xia Xueyi was startled, recalled in her mind, and said in disbelief: "Doesn't that mean that LED can achieve the efficiency and brightness of xenon lamps?"

"Not at this stage. Hu Wenhai shook his head, thought for a while, and added: "Let's start with relatively low performance, so that the market benefit will be more satisfactory." ”

Hu Wenhai's words sounded to Xia Xueyi, and she felt very sudden, and nodded hurriedly.

Xia Xueyi went to the United States once this time, and Xia Xueyi was also an eye-opener, it turns out that the capital market can still play like this! Even if there is mature technology in the laboratory, as long as the market is not saturated, she will never take the initiative to update the technology!

Wait until competitors have finally caught up, and then release a higher level of more advanced technology. After going back and forth like this, shuffling the cards several times, there are basically only one or two giants left in the market that can go sideways.

Similarly, you can probably look at Intel and AMD, agricultural enterprises are not just being played by Intel. And when AMD loses the ability to threaten the market, Intel loses the incentive to update its technology.

Of course, since Xinke has the technology of 120 lumens per watt, the application range of LED light source is not only extensive, but also promising.

The light bulbs in ordinary people's homes belong to consumables, and the profit is at the level of daily necessities, that is, the sales model of small profits and quick turnover. Of course, there are companies in the world that make a fortune by selling light bulbs, but how many companies in the market can achieve the level of Philips?

There's only one Philips.

But if LED lighting is not limited to home lighting, then its market prospects are immediately different. The demand for human lighting is very large, and some products and projects are not only the profitability of daily necessities, but the profitability of luxury goods.

For example, for automobile lights, the cost of a set of xenon lamp systems is less than a few thousand, and there is almost no upper limit. A 23,000-volt high-voltage pack alone makes the system many times more complicated. Although the energy consumption is lower than that of technologies such as incandescent lamps, it certainly does not have an advantage over LEDs, which are still in the laboratory at 120 lumens per watt.

Whether it is xenon, incandescent or fluorescent, they all have a very serious disadvantage, that is, they are earthquake resistant.

The "light bulb" has been a very fragile thing since it was invented by humans. This is determined by its own principle, in order to ensure a vacuum or inert gas environment, as long as thin-walled glass is used as the housing, there is no way to remove the fragile label.

However, the LED light source is different, because the LED is a semiconductor diode that emits light and is packaged in transparent resin, the shock resistance has been greatly improved. Its excitation circuit is simple and does not require the dangerous and complex boost of a xenon lamp. It has a low calorific value and does not have the high-temperature radiation like incandescent lamps. It has a long service life, which is unmatched by other lighting methods. It has good environmental performance and no pollution from fluorescent lamps......

And these characteristics also mean that LED light sources are more suitable than other light sources in one field - military.

The demand for reliability in military operations is overwhelming, and the military is known to be very generous when it comes to spending money.

It can be said that the emergence of LED white light source is a revolution for human lighting. The market prospect of LED light source can also ensure a big cake for military applications at worst.

The only thing that makes Xia Xueyi wonder is how the human body feels about the LED light source, is it comfortable, acceptable, or unbearable?

Hu Wenhai nodded, then beckoned, and a staff member had already walked over with a trolley.

On the aluminum alloy trolley are some LED lighting tools that have been installed, including table lamps, flashlights, light strips, light bulbs and other forms. In fact, the form does not make much sense for LED lights, because its luminous environment is not as limited as other light sources.

Hu Wenhai neatly turned on the power and pressed the switch, and the dazzling LED white light lit up from the small bulbs. The blue-white cold light was stimulated and radiated, filling the entire space in an instant.

Xia Xueyi squinted her glasses slightly, I have to say that the LED light is not as comfortable as an incandescent lamp, but a little dazzling.

Its white light is not really white, but a bit of a "miserable white" feeling. To be honest, such lighting cannot be said to be a pleasure for the human body.

However, in terms of daily use, there is absolutely no problem with acceptance.

That's enough.

As long as the product has no fatal flaws, the promotion basically depends on time. It will take five to ten years to promote LED lighting to the world, and gradually introduce products with better performance. In this way, while promoting and shuffling the cards, it is enough to make any opponent who vainly tries to compete with Xinke and Didu Imaging Tube Factory in this field want to die.

After the reshuffle in the lighting market is about the same level, LED lighting is not a defect, and users have no room for picking.

Wait until you have secured the position of market dominance, and then release the high-end application of LED lighting to realize the upgrading of the lighting system. This market of hundreds of billions of dollars a year will be completely held by Hu Wenhai.

"My plan is to be able to cooperate with the Imperial Capital CRT Factory and we will set up a new company together. With its current assets, the 798 plant can also hold a considerable part of the shares of the joint venture company through bank loans and application for state financial support. The company has invested in technology, equipment and patents, talents, etc., and the specific share ratio can be discussed. ”

Hu Wenhai said confidently: "The mission of this company, I hope, is not limited to the field of lighting. LED light source has more advantages in display technology, and soon there will be more new technologies launched. For example, more advanced color liquid crystal display technology and touch technology will become the basic pillar enterprises of the electronic consumer industry in the future, and become an indispensable part of Xinke's future electronic strategy. ”

"I don't know Director Xia, are you interested in this?"

Xia Xueyi hesitated a little, nodded, and shook her head again: "Of course I believe Mr. Hu's words, but there is one question, why me?"

"I mean, there should be no more suitable cooperation units than the Imperial Capital Tube Factory, right?"

When Hu Wenhai heard this, he thought about it and muttered: "You should be ...... Fate. ”

Actually, it's very simple, because you are the future "BOE".

Hu Wenhai can't bear to wait for this obscure but well-known enterprise to endure decades of hardships before it is reborn.

He wants to know,If BOE is given a fair chance,To what extent can it go? From the beginning,Can stand on the same starting line with their counterparts in Japan, South Korea and Treasure Island,China's display panel industry will not fall into the hands of the white-eyed wolf enterprises in Treasure Island as it did back then, right?

At least this time, 798 will no longer be a "mecca for petty bourgeoisie."

Hu Wenhai hopes that the term 798 in the future represents a miracle of Chinese science and technology.
