Siheyuan: I am Yi Zhonghai's biological son

Central Court Yijia

Meng Xiaoting returned to the middle courtyard after get off work and shouted as soon as she entered the door: "Mom, I'm back. Is my dad back?"

"Xiaoting, do you have something to talk to me about? I just got back too." Yi Zhonghai heard his daughter-in-law calling him and hurried out, followed by Tietou.

"Mom, you're back?" Tietou said as he slowly approached Meng Xiaoting. He also knew that his mother was pregnant with two younger brothers and he couldn't touch her, so he approached slowly every time.

"Dad, there's good news. Look at this." Meng Xiaoting hugged Tietou and took out today's newspaper from her bag.

"Newspaper? What good news?" Yi Zhonghai said as he opened the newspaper. An old lady also came over to take a look.

"Dad, look at this." Meng Xiaoting pointed at Yi Ping'an in the photo and showed it to Yi Zhonghai and his wife.

"What is this? Ping An! Ping An is in the newspaper!" Yi Zhonghai exclaimed and quickly picked up the newspaper to look at it carefully. It turned out to be a commendation meeting for advanced workers.

After reading the entire report and not finding Yi Ping'an's name, Yi Zhonghai realized that this was to protect him. Yi Zhonghai was a person who often signed confidentiality agreements and knew something about this.

"Dad, why is there no mention of Ping An in the report?" Meng Xiaoting was puzzled.

"This is for Ping An's own good. Xiaoting, put the newspaper away and don't tell anyone else about Ping An being in the newspaper." Yi Zhonghai said.

"Okay, I understand." Meng Xiaoting nodded.

In fact, as far as the home appliance project is concerned, Yi Ping'an is not too dangerous, at least there is no threat to his life. Those foreigners just want to bribe him. After all, innovation represents money.

The capitalists in the capitalist society are only interested in money, a steady stream of money. Otherwise, the leaders would not dare to let Yi Pingan attend the commendation conference. As Yi Pingan's R&D projects increase, he will one day come to the fore, but it can only be a home appliance project.

Although our national defense strength in this life is not as strong as that in later generations, no one dares to bully us. What Da Piao is doing now is more of a technological blockade and an economic blockade against us.

But the home appliances developed by Yi Ping'an broke this blockade. Coupled with the advanced development of the two bombs and one satellite and the sharp increase in oil and steel production, this life was advanced by 20 to 30 years, or even more.

After Meng Xiaoting returned to the cross-courtyard, she cut out the photos from the newspaper and pasted them on the briefing she had compiled. She touched her belly and muttered to herself, "I don't know when your father will be able to come back."

Yi Zhonghai asked the aunt to buy newspapers tomorrow and buy all the ones with this photo. He wanted to keep them as a souvenir. The aunt readily agreed.

..........................

Yi Ping'an returned to the research institute, put away his certificate of honor, and plunged into the laboratory again. He now wanted to overcome the difficulties of the rear-projection TV as soon as possible, and then take leave to go home for the New Year, which was only more than a month away.

As the name suggests, rear-projection TV uses a projector to project images onto a transparent screen, and then presents them to the audience through reflection or transmission, thus achieving high-definition, large-screen imaging effects.

Simply put, the projector is installed at the bottom of the body, and the signal is reflected and projected onto the back of the translucent screen for display, making the projector and screen one.

The biggest difference between it and a cathode ray tube TV lies in the processing after receiving the TV signal. After the rear-projection color TV receives the signal, it is processed by the circuit, and then optimized by the convergence circuit and digital filter circuit, and then transmitted to the three monochrome projection tubes of red, green and blue placed side by side.

The television images produced by the three projection tubes are magnified by lenses and reflected by mirrors onto the projection screen to form a complete large-screen color image.

The first generation of rear-projection products was produced in the late 20s and was successfully developed by small home appliance companies such as Toshiba and Sony. Although it had shortcomings such as poor clarity, low brightness, large-area flickering in the image, and inability to be viewed in sunlight, it has to be said that this was a breakthrough.

Because of the influence of the cathode ray tube, it is difficult to make a large television. However, rear-projection TVs are not affected by this and can be made as large as you want. Just like the LED display screens in large squares in later generations are a type of rear-projection TV.

The rear-projection TV developed by Yi Ping'an this time is the third-generation DLP rear-projection TV, which is the big-butt TV with a straight screen seen in the millennium. Compared with plasma and LCD, this type of DLP is the cheapest. Yi Ping'an plans to reap some profits first.

After the back-end products in Europe and the United States are on the market, we will then launch plasma and LCD products. "What others don't have, I have, and what others have, I have better", which will piss off these bastards to death.

The problem that Yi Ping'an needs to overcome now is the screen, which is one of the key components of rear-projection TVs. A parameter that we often talk about in later generations - resolution, comes from this.

After a month of hard work, we finally developed a high-gain screen, which is a screen commonly used by the Changhong brand in later generations in my country. It has good gain performance and good viewing angle.

This time the TV is a 42-inch TV. The high-definition picture and the grand texture are overwhelming. Compared with the - or -inch TVs of later generations, it is indeed a bit like a younger brother, but in this era, it is the boss.

The researchers in the group were all stunned, it was so beautiful. They also thought the previous cathode ray tube ones were beautiful, but after seeing this, they felt that they were really not good enough. Don’t say that they are fickle, everyone likes beautiful things.

Yi Ping'an asked someone to invite Director Liu, and Director Liu went to the debugging room as soon as possible. As soon as he entered the room, he was attracted by the majestic TV.

Director Liu lost his composure and grabbed Yi Ping'an's arm and asked him, "Is this a TV?"

"Yeah, if it's not a TV, could it be a movie?" Now that the new product is out, Yi Ping'an has time to joke.

"Don't use my cymbals. Explain what's going on." Director Liu slapped Yi Ping'an angrily.

"Boss, this is called a rear-projection TV. Compared with the previous TVs made with cathode ray tubes, its main features are that the screen can be made larger, the picture is clearer, and the sound quality is also stereo..."

Yi Ping'an reported the advantages of the rear-projection TV to Director Liu one by one, and told Director Liu not to hand over the TV in immediately, but to wait until at least next year.

"Why do we have to submit it next year?" Director Liu didn't understand.

"Boss, our remote-controlled TV will just be launched next year. If we rush to launch rear-projection TV, it will impact our own market. Even if you want to submit it, you have to tell the Ministry of Foreign Trade that this rear-projection TV can only be launched in two years."

Yi Ping'an told Director Liu about the practice of "cutting leeks" in later generations. After hearing it, Director Liu looked at him with a strange look in his eyes.

"Mr. Yi, I didn't expect you have the potential to be a profiteer." Director Liu joked with Yi Ping'an.

"Leader, this is just common economic theory. How can it be considered as profiteership? It's okay, okay?" Yi Ping'an would never admit it.

"So what are you going to do with this one?" Director Liu asked Yi Ping'an.

"It's your job as a leader to figure out how to handle things. I only do research and development. Where do the results of research and development go? That's none of my business." Yi Ping'an said and glanced at Director Liu jokingly.

"Hey, don't look at me like that. I don't dare keep it. I'd better send it up. The New Year is coming soon. Just think of it as a New Year's gift to the leader. I'll have someone come in and pack it."

Director Liu looked reluctant to leave as he watched the TV being packed up bit by bit, then sighed helplessly. Yi Ping'an wanted to laugh, but he didn't care whether the old man sighed or not. He wanted to take a leave to go home for the New Year.

"Boss, I'm going to take a leave tomorrow to go home for the New Year. When I come back after the New Year, I'll organize the drawings and materials of this rear-projection TV and give them to you. What I can give you now is the materials for applying for the patent, which I have organized."

After Yi Ping'an finished speaking, he handed Director Liu a sealed file bag.

After receiving it, Director Liu asked Yi Ping'an in confusion: "Why do you want to give me the drawings after the New Year?"

"I'm afraid you can't stand the pressure and hand in the drawings directly. If you don't have the drawings, you can shirk responsibility and say that the drawings are too complicated this time, and even the screens are high-tech, so they need to be sorted out slowly. Of course, if you think it's okay, I can sort it out tonight and give it to you."

Yi Ping'an really needs to sort out the drawings and reports this time. He needs to replace many names with current terms, and those nouns that have never appeared before also need to be replaced according to China's terms.

"Don't give it to me. Just keep it with you, but be careful about its safety. If you really can't afford it, put it in the safe." Director Liu also knew that he couldn't stand the pressure.

"I understand. I will go home tomorrow. I wish you a happy new year in advance!" Yi Ping'an said and bowed to Director Liu.

"Happy New Year to you too!" Director Liu returned the greeting.

After Yi Ping'an returned to the dormitory, he began to pack the things he would take back with him. Thanks to the foreign exchange, Yi Ping'an received a lot of things for the Chinese New Year, not to mention rice, flour, grain and oil, but also a lot of meat and eggs, even Jinhua ham and other things.

What made Yi Ping'an happy was that this time there were two boxes of milk powder, which Wang Kaixuan specially exchanged with the logistics department.

The next morning, Yi Ping'an and Wang Kaixuan loaded the things they were going to take back into the car, stuffed it full, and drove towards the courtyard.
