On the LCD production line of the Chunjiang County Strengthening Headquarters, He Qiang has grown a little taller than before, and wearing a protective hat in work clothes is no longer as funny as before, and he who was originally standing in the operation position took a step back.

"Dong Li, it's better for you to do it yourself."

Li Jian, who was standing behind He Qiang, hurriedly waved his hand, "It's all you guys fiddling these days, I can't even surround the side, don't you want to see me make a fool of myself." ”

He Qiang smiled at several Qianghua engineers behind him, no longer insisted on Li Jianlai to operate, turned around, and began to operate the CNC machine tool imported from Japan.

The wafer factory is under construction, but Li Jian ordered two more CNC machine tools than he was scheduled to be proficient, one was placed here, and the other was placed in Qianghua Laboratory.

The agreement signed by Jianyou Company is not allowed to produce machine tools and equipment, and Li Jian also noted when signing the contract that Qianghua does not use these machine tools to produce machine tool parts, but he did not say that he could not take them for study.

Especially when the time comes, other machinery companies, such as Lin Kaihe's original Shengli Machinery Factory, can learn these machine tool manufacturing technologies, and then produce machine tools, but it has nothing to do with Qianghua.

As for how to produce machine tools to compete with other manufacturers in the international market, it is necessary for these machinery factories to develop new technologies, otherwise they can only produce equipment for domestic digestion.

Now the mission of this machine tool is to carry out liquid crystal cutting, in addition to the reform of display technology, the division between generations is completely divided according to the size, that is, the number of pieces that a glass substrate can cut.

It is generally accepted that the optimal number of pieces to cut a liquid crystal glass substrate is generally six. For example, the size of the third-generation TFT substrate is 550MMx650MM, which can be cut into four fifteen-inch LCD displays. The fourth generation is 680x880 and can be cut into six pieces, and the fifth generation can be cut into twelve pieces of 17 inches or six pieces of 24 inches, and no company will use a complete glass substrate to make a display.

Of course, the current LCD technology has not yet developed to the third and second generations, let alone the fifth generation, and the LCD production line in front of Li Jian was still an obsolete production line imported from Japan at that time. Although Li Jian has adjusted the liquid crystal materials, it is still a black and white liquid crystal production line.

What we need to do now is to test the cutting of the LCD panel by the CNC machine tool, Li Jian's next goal. It is to transform this LCD production line into the first generation of color LCD production line.

Color liquid crystal is very different from this kind of gray liquid crystal alone, first of all, technically speaking, gray liquid crystal only needs to display one color, that is, gray. That is, the difference between transparent and opaque. The more opaque it is, the clearer it is.

The color liquid crystal is bound to use ternary color, that is to say, at the same point, there must be three colors of light source, in order to be able to display various colors according to different proportions, this difficulty is much more difficult than the difficulty of monochrome liquid crystal.

Li Jian wanted to get color liquid crystal out for a long time. But because the time is too tight and the color liquid crystal is not the most important, it has been delayed until now.

He Qiang pressed the button on the machine. Cautiously began to operate, after a movement, he stopped moving, looked at the tool on the machine, according to the pre-programmed program, cutting on the glass substrate, several people looked at the end of the action, a heart has been suspended.

It may seem simple, but only those who do this work can understand that cutting is a critical part of it, and if something goes wrong when cutting, it is a waste of work.

In the past, cutting LCD screens was basically done manually, although the efficiency was inevitably reduced, but it could be adjusted appropriately according to the specific situation, and there was no need to worry about the entire glass substrate being discarded.

Seeing the normal operation of the cutter head on the glass substrate, the glass substrate was cut into a rectangular piece like a cake, and then the cutter head was lifted again, and the uncut part fell, and one after another the LCD panel was cut off, put into the conveyor belt next to it, and teleported out.

"Okay, now it's okay, we can save more than half of the manpower, Li Dong, with the automatic cutting equipment, your color LCD can start."

He Qiang looked at the effect of the cutting, his face was full of smiles, although he was blocked behind the mask, he could still see it from the corners of his eyes, he was really happy.

"Okay, you see your kid happy, let's go, follow me to debug the blue display layer, the red and green ones have been debugged, just wait for the blue debugging to finish, let's start to do it, make the world's first color LCD display."

Li Jian patted He Qiang's shoulder, this child has grown up completely, in the LCD production workshop, he is the youngest, but including which engineers invited from Japan, all admire this child, although there is no formal appointment, but the entire workshop people, unconsciously regard He Qiang as a manager.

Anything in production, I want to talk to He Qiang about it, and He Qiang really didn't disappoint them, no matter what difficulties come to He Qiang's hands, the final result is a perfect solution.

Of course, these are also inseparable from He Qiang's efforts, although he doesn't like to go to school, but he has never relaxed about learning, through his brother He Chao bought a lot of books about liquid crystal and materials from outside, and found that there was something I couldn't understand, so I bought a lot of chemistry books and physics books, and then bought advanced mathematics, a child who didn't even graduate from junior high school, just read books, and finished learning mathematics, physics and chemistry in college, although the level does not know what it is, but now the liquid crystal production line is a thing, which is no longer difficult for him.

And the resilience of this child also made all the workers admire, some problems to He Qiang's hands, not smoothly solved, He Qiang has a problem that he doesn't understand, simply in addition to eating, sleeping and going to the toilet, all the time is put on the production line, specifically for these problems to study, how many problems were solved by He Qiang like this, they don't know.

If such a person does not grow into a talent, what kind of person can grow into a talent?

So at this moment, Li Jian didn't call anyone else, but asked He Qiang to do the blue display experiment, and no one else had He Qiang's ability.

Coming out of the LCD workshop, the two of them did not take off their protective clothing, but entered the slope workshop on the other side from the small door.

A huge table is a test bench, on which there are all kinds of materials used for liquid crystal production, it looks messy, there are no rules, but Li Jian and He Qiang both know that these are placed in the order they need to use.

For example, photoresist, which is used the most often, is placed in the most suitable position.

"Dong Li, are you ready for the blue materials?"

Since He Qiang was subjected to He Chaoxiong a few times, he has already changed his title to Li Jian from Brother Li Jian to Li Dong, and Li Jian has corrected it several times after listening to it, but it has no effect, and he is now used to it.

"Well, these are the liquid crystal materials used in blue display, these are the need to use polymer chemistry knowledge, although you have learned a lot, but this part of the knowledge has not been mastered, I have asked people to bring you a few books from abroad, you take the time to take a look, if you can understand, I will give you this part of raw material production, whether you can do it depends on whether you can learn it yourself."

Li Jian has inspected He Qiang's chemistry knowledge, after all, it is only self-study, and a lot of knowledge is memorized by rote, but when it comes to integration, it has not yet been achieved, and Li Jian obviously wants to promote He Qiang's learning through this matter, so the materials he bought are all English versions, if He Qiang wants to understand, it is better to learn English first.

In this way, although this kid didn't go to junior high school or high school, his actual level may have already surpassed that of ordinary college students.

"Well, Li Dong, don't worry, as long as you bring the book, I will study it seriously, I don't want to go to school, I don't like that kind of learning environment, I know a lot of things, I still have to listen to it somewhere, I have to do the questions repeatedly, just to improve the score of the exam, this kind of learning is a pure waste of time."

He Qiang snorted, skillfully picked up the gloves on the table, and then carefully picked up the glass substrate, put it into the dilute solution that Li Jian had prepared next to him, and cleaned the glass substrate cleanly, then put it aside, and began to prepare other things.

Li Jian looked at He Qiang's movements, as if he was very skilled, it seems that He Qiang, this kid is indeed a talent, and he has not wasted his own training efforts in vain, as long as there are a few more such talents, why worry that his Qianghua company will not rise.

The glass substrate in He Qiang's hand is very small, only the size of a book with thirty-two openings, so it is very convenient to operate, and all the procedures will not take long.

Li Jian hurriedly took over the other two LCD panels of the same size that had been formed next to them, which were the results of their first two work, red and green LCD panels, waiting for the blue LCD panels to be made, and then overlapping the three to ensure that each pixel has three colors of meta-color, which can display different colors according to different brightness.

The control of the brightness of each color needs to adjust the current size on each LCD panel, and the perfect control of the current can perfectly control the image of the LCD display.

"It's done, Dong Li, I'm going to glue them together."

He Qiang's work at hand had been completed, and he reached out to take the two substrates in Li Jian's hand...... (To be continued......)
