Rebirth 84 Everything depends on hands

"Director Chen, you...you want to change the current picture tube technology?" Qian Jiang was no longer calm, and even the hand holding the drawing began to tremble.

Chen Feng looked at the corner of his mouth and smiled slightly, then clapped his hands and said, "Sure enough, he is a scientific researcher from the province. You can see it at a glance."

Qian Jiang's forehead is now covered with sweat. Director Chen's idea is too bold. He never expected that he would receive such a huge task on the first day he came to this small electronics factory in Beicheng City.

.

Everyone present was surprised. Chen Feng really dared to think about it. It is difficult to even popularize television now. Director Chen actually wants to change the current television technology. This is simply a fantasy.

"Director Chen, you..." Qian Jiang didn't know what to say. As a factory director, it's good to have such an understanding, but this country is still importing other people's things, and you actually want to change,

This is so unbelievable.

"You are too bold. Let's not say whether it can be done. Just a few of us scientific researchers are far from enough." Qian Jiang said awkwardly, "There are too many things involved."

"That's right, Director Chen, this is a big topic for you. Not to mention our factory, I'm afraid the country will have to study it for several years if it wants to study it." Chen Shuhua also persuaded Chen Feng as it was extremely unlikely that the research would be successful.

Chen Feng smiled and waved his hand, "Although this subject seems big, it is not that complicated." Chen Feng, who came from later generations, was not like this group of people and was already very familiar with this technology.

"Everyone knows that the reason why today's TV screens are spherical is because of the high external air pressure when the picture tube is evacuated."

"The degree of bulge in the middle of the TV screen is expressed by the radius of curvature. That is to say, the lower the radius of curvature, the higher the degree of bulge. The current radius of curvature is mostly below 1000 mm. And now some countries have developed curvature radius

If it is larger than 2000 millimeters, it is already very close to a plane, but it is only close, not a complete plane!"

Chen Feng, who said this, glanced at Qian Jiang and others, "The most important point, they haven't studied it thoroughly yet, the most important point is the beam gun!"

Among the people here, except for Xu Haiyang, everyone is the backbone of the electronics factory in terms of technology, so what Chen Feng said is easy to understand. Especially Chen Jianguo, I have read about this aspect in some electronic magazines.

Now that Chen Feng has spoken out about the report, he feels very relieved that his son has not given up his job just to make money.

"There are three electron guns in a traditional color picture tube, which emit three electron beams respectively. After the electron beams pass through the TV shadow mask, they hit the screen and hit the phosphor. The phosphor on the inner surface of the screen is bombarded to make the image appear colorful.

"

"What we are going to study now is to use a single panoramic focusing electron gun to emit three electron beams separately, causing the red, green and blue phosphors on the inner surface of the screen to emit light individually, thereby forming an image."

After Chen Feng finished speaking, everyone looked at Chen Feng quietly. After hearing Chen Feng's nonsense, Qian Jiang lowered his head, frowned and thought carefully, using his own knowledge to constantly confirm Chen Feng in his mind.

Feng said, and finally came to the conclusion that what Chen Feng said is completely achievable in theory.

"Chen Feng, what will the final result of changing the electron gun you mentioned have on the TV screen? Will it improve the quality of the picture, or something else?" Chen Jianguo was also thinking, and asked Chen Feng while thinking.

"It can prevent the edges of the TV from being blurred or distorted," Qian Jiang said from the side before Chen Feng could answer, "It can improve the color quality of the TV, and it is possible..."

Qian Jiang said that he did not continue here because he was a little unsure about the subsequent changes and looked up at Chen Feng.

Chen Feng smiled. This time he had to go and thank Luo Dahai for finding such a treasure for himself. As soon as he said it, he knew what changes it would bring.

"Technician Qian, keep talking and say everything you think of." Chen Feng encouraged Qian Jiang with a smile.

"The smaller the pipe diameter and the smaller the depth, not only can it achieve a completely flat effect, but it can also expand the display size of the TV screen!" Qian Jiang took a breath and said, "It should be about 30 inches!"

"30 inches!" Everyone here opened their eyes. The largest TVs on the market now do not exceed 20 inches. A technological reform can actually make the TV set that big? Good guy, what if we make this?

How clear is it to watch TV series on a 30-inch TV!

"Chen...Director Chen," Chen Shuhua was a little surprised, "How long will it take to develop this technology? If our factory can produce such a large TV set, it will sell like crazy!"

Chen Feng smiled and said, "Master Chen, if you want to develop this technology, it will take a year and a half at the fastest. If it is slower, it may take several years."

After hearing it for so long, everyone's excitement suddenly disappeared.

Chen Feng glanced at everyone and said, "No matter how long it takes, our electronics factory must study this technology. I will leave this matter to you, Comrade Qian Jiang."

"I'll have people clean up your office in a while and clean up the laboratory for you. If you have any difficulties in the future, you can ask me. I will help you get everything you want as soon as possible. In addition, I am at Beicheng University

An experimental base has also been established. If you need anything, you can also go to the school's experimental base."

Chen Feng looked at several people and said. After Qian Jiang and others looked at each other, Qian Jiang nodded solemnly to Chen Feng.

Chen Feng smiled and took out another drawing from the folder, "It takes too long to research the electron gun, and it has not greatly improved the efficiency of the factory. So while you are researching the electron gun, you will research a simple one for the time being.

."

Qian Jiang took the drawing handed to him by Chen Feng. There was something drawn on it. You said it was a tape recorder, but it was too small and it didn't have a speaker. But you said it wasn't a video recorder. Look at the picture.

That means it can also put tapes inside.

"Director Chen, what is this thing?" Qian Jiang obviously didn't understand what it was and looked at Chen Feng with some suspicion.

This factory director really has an unusual brain. I can still understand the theory about picture tubes that I just mentioned. Now I have never seen this thing. This factory director thinks about everything in his head all day long, and he can become a scientist.

"Walkman!" Chen Feng said with a smile, "This thing is simple. It just makes the recorder smaller and removes the recording function. It only has play, pause, forward and backward, and there is no speaker. You need to use headphones to listen."

"Pfft!" Qian Jiang spat out a mouthful of water and looked at Chen Feng with wide eyes. You call things simple. It doesn't mean that the change is big, but the entire circuit board has to be changed. To put it bluntly, it is redoing a product.

, you actually said it was simple!
