Military Industry of Great Powers: Build the Strongest Flanker.

Chapter 214 Japan can say no

That's it for 2G. It was at its peak when it debuted. If you want to make breakthroughs in communications, you can only develop in 3G.

However, there are still many areas for development of 2G mobile phones.

For example, the Snake game is simple and decompressing. It is simply a time-killing tool in this era.

The same goes for playing volleyball. There is a line in the middle of the screen, and then a small black dot, hit it here, hit it...

Of course, Teacher Xiao Zhao wants to install a camera on a mobile phone. The CCD chip can already achieve 50,000 pixels. However, with the miniaturization of the CCD chip camera component, the second one is the screen.

You can’t always take photos and display them in black and white pixels!

Zhao Guoqing visited the top-level Sinocom R&D Center and answered some questions encountered by R&D personnel.

In the lithium battery R&D workshop, chief engineer Zhang Xinyan shook her head helplessly when faced with the experimental results.

The core technology of lithium batteries is a thin film that isolates the positive and negative electrodes, but it cannot be completely isolated. The ions in the electrolyte need to be able to pass...

This is life-threatening. How to make the film and evenly distribute the gaps of about 50 nanometers.

Zhang Xinyan’s solution is dry pull.

During the preparation process of the separator, raw materials such as high molecular polymers and additives are mixed to form a uniform melt, and a lamellar structure is formed under tensile stress during extrusion.

The lamellar structure is heat treated to obtain a hard elastic polymer film, which is then stretched at a certain temperature to form slit-like micropores, and then heat-set to form a microporous film.

When this plan was reported to Zhao Guoqing's desk, Zhao Guoqing approved it. The dry method is indeed a way, but now it seems that without precision processing equipment, there is no way to ensure the size and porosity of the holes.

"Mr. Zhao!" Zhang Xinyan felt a sense of frustration. Zhao Guoqing knew her feelings very well. Scientific research means constant trying. There are walls all around. Even if you hit a wall, you may not have results.

In fact, only a few lucky people succeed.

But can you say that these failed people are worthless and that they have made no contribution to scientific research?

Definitely no.

Zhao Guoqing said: "Think about it another way, what particles are around 50 nanometers. If you mix these particles into the film when preparing the film..."

Smart people will tell the truth. Zhang Xinyan jumped up and said: "Use a solution to dissolve these small molecules, and we can get a polyethylene film that meets the requirements. Mr. Zhao, you are so awesome. This idea is simply...genius..."

This is the wet production process, also known as phase separation method or thermal phase separation method.

Liquid hydrocarbons or some small molecular substances are mixed with polyolefin resin. After heating and melting, a uniform mixture is formed. The temperature is then cooled for phase separation and pressed to obtain a film. The film is then heated to a temperature close to the melting point and biaxially stretched to make the molecules chain orientation.

Finally, keep the temperature for a certain period of time, and use volatile substances to elute the remaining solvent to prepare interconnected microporous membrane materials.

If Zhang Xinyan and his team were to explore the entire process, it would probably take another two or three years. Teacher Xiao Zhao could not afford to wait for this time.

He directly explained several nodes of the process and put forward technical requirements. The more he said this, the more confused Zhang Xinyan's eyes became, and Teacher Xiao Zhao also looked uncomfortable.

Zhao Guoqing said: "As you can see, lithium batteries are very important. You thought I put all my chips on you. I also invested money in several university research institutes. These are other people's achievements..."

As soon as she said this, Zhang Xinyan blushed, lowered her head and said, "Mr. Zhao, we will work hard..."

The entire team looked like children who had done something wrong, with guilt on their faces...

Forehead!

Zhao Guoqing hurriedly comforted him: "You have done a good job. Really, I am very satisfied..."

"Mr. Zhao, stop talking. We get more than 3,000 yuan a month and have accomplished nothing. This money is very hot. Mr. Zhao, we are asking for a salary cut!"

"Mr. Zhao..."

"What a lovely person!" Zhao Guoqing nodded. It was not because they asked Zhao Guoqing to pay less, but because of his sense of responsibility... "Don't you regret it?"

"No regrets!"

Zhao Guoqing smiled and said: "Okay, then I will deduct half of your salary. Starting next month, each of your salaries will be discounted in half. If results are achieved, the deducted money will be multiplied by five times and given to you as bonuses. If not, As a result, you will receive a salary of more than one thousand from now on..."

"Mr. Zhao..."

Zhao Guoqing waved his hand and said no more. After walking out of the lithium battery R&D workshop, Zhao Guoqing came to the LCD panel R&D workshop.

Research on LCD has been ongoing and many achievements have been made.

One is the glass substrate, which is a thin glass sheet produced by float method with a flat surface. A transparent conductive layer of zinc trioxide or tin dioxide is evaporated on the surface, that is, the ITO film layer. After processing, it is made The transparent conductive pattern has been solved with the technical support of Wuyou Institute.

The second is the liquid crystal material that has troubled China for decades. Liquid crystal material is the main part of the liquid crystal display panel, and different devices may use different liquid crystal materials.

Liquid crystal materials are mostly mixed from several or even dozens of single liquid crystal materials.

The liquid crystal materials currently studied include benzoate esters, biphenyls, terphenyl compounds, phenylcyclohexyl compounds, biphenyl ring compounds, etc., each of which has hundreds or thousands of species. Material.

There are dozens of types of liquid crystal lattices. If you don't have the foundation to start directly, you will have to explore tens of thousands of ways before you can find a way.

There are thousands of roads, but Teacher Xiao Zhao can only choose one with his finger, and the progress is good.

As for the last difficulty of TFT LCD screen, thin film transistor, well, I have encountered Mr. Zhao’s knowledge blind spot.

This is also the reason why Zhao Guoqing introduced Samsung's TFT LCD panel production line.

As for the color display.

The principle is to fill liquid crystal material between two parallel plates, and use voltage to change the arrangement of molecules inside the liquid crystal material to achieve the purpose of shading and transmitting light to display images of different shades and staggered patterns.

It is still very difficult to accurately control the liquid crystal steering of each pixel. Zhongxun lacks the basic accumulation of liquid crystal technology.

Zhao Guoqing hopes that Samsung can make up for Zhongcom's shortcomings, while Li Jianxi believes that they can defeat Zhongcom in the future competition of 13-inch TFT LCD screens.

Business is not about treating guests to dinner, it is about life and death...

……

Samsung came to Shenzhen to seek cooperation with Zhongxun.

At this time, at Motorola headquarters, Hideo Kojima, President of Sony Corporation, was asking to see President Tommy.

The little devils were unwilling to admit their lagging behind in WCDMA technology in front of Zhongxun, so they set their sights on Motorola.

There is no psychological pressure on them to seek help from Americans.

But Tommy didn't even give President Kojima a chance to meet. He just asked his sexy and enchanting secretary, Ms. Malefielle Fiacre, to hand Hideo Kojima a book.

Hideo Kojima took it in his hand and saw that the title of the book was "Japan Can Say No", written by Sony founder Shao Morita two years ago.
