The figure of the Ningguang 3.1 lithography machine appeared in Xia Xueyi's sight through the glass of the visiting passage, making him unable to help but breathe.

This is a machine similar to a huge filing cabinet, with two rows of dark glass doors on the upper and lower sides, and an RT monitor is placed inside the glass door on the upper right side.

At this time, some equipment operation data are displayed on the monitor, and the values ​​are changing slowly but not much fluctuating.

On the surface alone, it is hard to believe that this inconspicuous device is the most difficult lithography machine in the electronics industry.

In fact, what Xia Xueyi saw was not a lithography machine used for the previous process, but a package lithography machine used for the next process.

There are first and second paths for lithography machines. The front path process has higher technical content and higher requirements for production conditions. It is mainly used to process the internal circuits of the chip. The latter path is used for packaging, and it processes the slightly lower processing requirements of the chip, such as the external circuits, shells, pins, etc.

As the progress bar on the monitor was completed, the lithography machine emitted a beeping sound, and soon a staff member rushed over and took out the LED chip that had been packaged from the package lithography machine.

After the photolithography part, the subsequent processing process is faster. After etching, circuit deposition, chip cutting, external housing packaging and other processes, the LED lighting circuits will be produced.

Not long after, these first batch of industrially produced LED luminescent chips in the world were sent to Hu Wenhai and Xia Xueyi.

"Is this the LED luminous chip?" Xia Xueyi excitedly studied the inconspicuous chip in her hand over and over again.

Unlike ordinary chip packaging, LED chip packaging uses transparent resin, which directly exposes the chip's gallium nitride circuit to the naked eye. At this time, what Xia Xueyi is most concerned about is how effective the small chip in the square inch has.

Although Xia Xueyi has already memorized the relevant data of LEDs and has a clear understanding of its core advantages and luminescence principles, it is ultimately because hearing is false and seeing is true. Whether LED lighting can replace other light sources on the market today cannot be described only through data.

Hu Wenhai nodded and explained: "Its substrate is single crystal silicon, the luminescent material gallium nitride, and the excitation material is yttrium aluminum garnet. Part of the blue light emitted by gallium nitride excitates yttrium aluminum garnet to produce yellow light. What the human eye observes is approximately white light generated by the mixing of blue light and yellow light."

"The LED luminous brightness is very high, but the energy consumption is 25 lumens per watt, which is nearly twice the efficiency of an incandescent lamp, and is almost the same as a tungsten halogen lamp. But this is not the limit of LED luminous emission. Our laboratory has achieved a luminous efficiency of 120 lumens per watt, but it has not yet been put into production."

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

"It's not possible at the moment." Hu Wenhai shook his head, thought for a while, and added: "Let's start with relatively low performance, so that the market benefits will be more satisfactory."

Hu Wenhai's words seemed to be very enlightened to Xia Xueyi, and he nodded quickly.

This time I went to the United States, Xia Xueyi was also very eye-opening. It turned out that the capital market could still play like this! Even if there is already mature technology in the laboratory, as long as the market is not saturated, we will never take the initiative to update the technology!

After the competitors finally catch up, they will release the more advanced technology from the next level. After a few reshuffles, there are basically only one or two giants left in the market to walk sideways.

Similarly, you can probably look at Intel and Amd. Agricultural enterprises are just being played by Intel to death. And when Amd loses its ability to threaten the market, Intel loses the motivation to update technology.

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

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

There is only one Philips.

But if LED lighting is not only limited to home lighting, its market prospects will be different immediately. Human lighting market demand is very large, and some products and projects are not only profitable for daily necessities, but also profitable for luxury goods.

For example, car headlights, a xenon lamp system cost less than a few thousand, and there is almost no upper limit for the most. Just a 23,000-volt high-voltage package makes this system complicated many times. Although the energy consumption is lower than that of incandescent lamps and other technologies, it will definitely not have any advantages over the LEDs that are still in the laboratory now, which are 120 lumens per watt.

Whether it is xenon lamps, incandescent lamps or fluorescent lamps, they all have a very serious disadvantage, that is, their shock resistance.

"Light bulb" is a very fragile thing since it was invented by humans. This is determined by its own principles. In order to ensure a vacuum or inert gas environment, as long as thin-walled glass is used as the shell, the vulnerable label cannot be removed.

However, LED light sources are different. Because LED is a semiconductor diode that emits light, it uses transparent resin to package it, and its shock resistance is greatly improved. Its excitation circuit is simple and does not require dangerous and complex boosting like a xenon lamp. Its heat generation is low and there will be no high-temperature radiation like an incandescent lamp. It has a long service life, which is beyond the reach of other lighting methods. It has good environmental protection performance and does not pollute the environment by fluorescent lamps...

These characteristics also mean that LED light sources are more suitable for military purposes than other light sources in one field.

The requirements for reliability in military operations are overwhelming, and as we all know, the army has always been very generous in spending money.

It can be said that the emergence of LED white light sources is a revolution for human lighting. The market prospects of LED light sources can at least ensure the big cake of military applications.

The only thing that puzzles Xia Xueyi is how the human body feels with the LED light source? Is it comfortable, acceptable, or unbearable?

Hu Wenhai nodded, then waved, and some staff members were already pushing the cart.

The aluminum alloy trolley is placed on some LED lighting tools that have been installed, including desk lamps, flashlights, light strips, light bulbs and other forms. In fact, the form does not mean much to LED lamps because its luminous environment is not as limited as other light sources.

Hu Wenhai turned on the power neatly and pressed the switch. The dazzling white LED light lit up from the small light bulbs. The blue and white cold light was stimulated to radiate and instantly filled the entire space.

Xia Xueyi narrowed her glasses slightly. I have to say that the LED lights are not as comfortable as incandescent lamps, but are slightly dazzling.

Its white light is not a real white light, but a bit "pale". To be honest, such light cannot be said to be a pleasure for the human body's feelings.

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

This is enough.

As long as the product has no fatal flaws, it basically depends on time to promote it. It takes five to ten years to promote LED lighting to the world, and gradually launch products with better performance. This way, while promoting and shuffling it, is enough to make any opponents who want to compete with Xinke and Diduo Image Tube Factory in this field, and they are ecstatic.

After the lighting market is reshuffled at an almost-six level, LED lighting is not a defect, and users will have no room for pickiness.

When we firmly take the position of the market overlord, we will release high-end applications of LED lighting to achieve the renewal of lighting systems. This market with a total of over 100 billion US dollars per year will be completely held by Hu Wenhai.

"My plan is to cooperate with the Diduo Image Tube Factory to jointly establish a new company. Factory 798 can invest in its current assets, and can also occupy a considerable number of shares in the joint venture through bank loans and applying for national financial support. Xinke invests in technology, equipment, patents, talents, etc., and the specific share ratio can be negotiated."

Hu Wenhai said confidently: "I hope that the mission of this company is not only limited to the lighting field. LED light sources have more advantages in display technology, and Xinke will soon launch more new technologies. For example, more advanced color LCD display technology and touch technology will become the basic pillar enterprise of the electronic consumer industry in the future and become an indispensable link in 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 only one problem, why is it me?"

"I mean, there should be many more suitable cooperative units than Didu Electronic Tube Factory, right?"

Hu Wenhai thought about it and pondered: "Just treat it as... fate."

Is the reason? It’s actually very simple, because you are the future “BOE”.

Hu Wenhai couldn't bear to wait for this unknown but famous company to endure decades of hardship before he was reborn from the ashes.

He wanted to know, if BOE was given a fair opportunity, how far could it do? From the beginning, it could stand on the same starting line with its peers from Japan, South Korea and Baodao. China's display panel industry would not fall into the hands of the group of ungrateful companies like it did back then, right?

At least this time, 798 will no longer become a "holy land of petty bourgeoisie".

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