Coquettish Rebirth

The liquid crystal was first discovered by a company called rca in the United States. RCA, which is the full name of the company Radio Corporation of America, used to be the overlord of the television industry in the United States.In the 60s, one of their researchers discovered that the liquid of certain things would suddenly change from a transparent state to a white state under a certain electric field condition, but the internal substances did not undergo chemical changes, but were completely physical changes— —Because of the electric field, the internal crystal order of the liquid state changes, so the overall refractive index changes, so the appearance color also changes!This is the principle of liquid crystal.

In 1966, two scientists in the RCA company first studied liquid crystal materials that could work at room temperature, and they were very promising to make so-called LCDs—that is, liquid crystal displays.At this time, the U.S. military is very interested in this, because at this time, the various displays on many U.S. combat platforms are still very good. place!

So the U.S. government invested a lot of money in rca, asking them to study this kind of stuff, but after 5 years of research, the staff of rca company felt that although they had made a key breakthrough in the lcd project, due to various The reason is that this LCA cannot be mass-produced in a large scale, and the yield rate cannot be guaranteed, and there is no way to provide it to the army-after all, it is different from China.The military items in the United States are all purchased, and the low yield rate will lead to huge prices!At the same time, in another studio of rca, the legendary color picture tube has been researched, so seeing that the TV will soon be able to use the color picture tube to become color se, so in the end rca directly gave up the lcd project.

After the Americans gave up this plan, Ri himself discovered the advantages of this project.So they purchased this project, but they didn't think about making this lcd the size of a TV screen, but only made a monochrome display that can only display 8 numbers and only one line!The yield rate of a 13-inch large display screen is not high, but the yield rate of such a simple small display screen is high?Ever since, a calculator with an LCD screen soon appeared in Japan.This kind of calculator is lighter, smaller and cheaper than traditional calculators, and soon this kind of calculator was directly sold back to the United States!The first Japanese manufacturer to buy LCD technology from the United States is named Sharp.By 2012, among the hot naked-eye 3D LCD screens in the world, Sharp was still the best.In 2012, in the list of manufacturers with the highest level of LCD technology in the world, the top few must have the name of Sharp...

"Sharp is a leader in TFT screens. They made the first color setft LCD screen in history in 87 and used it on watches. The meaning of this TFT LCD screen is that each pixel has a A small transistor, this transistor is responsible for the pulse current. So to speak. For example, a 5-inch 640*480 resolution TFT LCD screen, then there is a 5-inch film under the screen, and this film has a 640*480 transistor , each transistor is responsible for the current pulse, stimulating each LCD pixel to change the color. So this tft screen is called true color. Their color is brighter, the contrast is higher, and the sense of layering is stronger. The only disadvantage is that it is relatively It costs electricity..." Ni Guangnan is now popularizing the history of liquid crystals with Jia Hongjian.

After hearing this, Jia Hongjian suddenly remembered something.He remembered that a few years after he graduated from university, it happened to be the era when mobile phones were replaced with color screens.At that time, there seemed to be all kinds of color LCD screens, such as tft, and what else... stn?It seems that in theory stn is not as good as tft?Thinking of this, Jia Hongjian asked Ni Guangnan, "Is there an stn screen?"

"Little Mr. Jia, do you still know about STN?" At that time, Ni Guangnan really looked at Jia Hongjian with admiration!It's not surprising that he, Ni Guangnan, knows all this.Why is he a double academician of the Chinese Academy of Sciences and the Academy of Engineering, and he is one of the top talents in the domestic IT industry. Although LCD is not his major, he also works with it.It is normal for him to know a little bit about the relevant knowledge.But Comrade Jia Hongjian’s major is doing business!Is to do the market!Not doing technology!Jia Hongjian actually knows professional terms like stn, that's really good!

"The stn screen means a super-twisted nematic liquid crystal display screen. To put it bluntly, a color filter is added behind the traditional single-se screen, and each pixel in the single-se display matrix is ​​divided into The three pixels display red, green, and blue primary colors through color filters, so as to achieve the function of displaying colors... This seems a bit professional, anyway, the stn screen, the patent is in a previous rca In the hands of a technician, this person left rca and went to a company in Switzerland to register this patent. Compared with tft, this stn screen is a passive screen, which is only available by folding an additional light source The use of color is a kind of heresy, so their color will be limited by the ability of the filter, and the contrast is not high, and the color is not too bright. The industry calls this kind of screen a pseudo-color screen, but this screen is power-hungry. smaller……"

Hearing this, Jia Hongjian probably had a clue.If it is just for the first color screen mobile phone in 97, then you can use the stn screen, and even temporarily use the stn screen to fool around in the next 5 or 10 years, but if you want to do it really well, you still have to use tft Screen!Because only by researching in the mainstream field of LCD, can we get a share of future LCD monitors and LCD TVs!

For example, the Samsung in the Cosmos Bangzi Country has never heard of their LCD screens in this era, but in 2012, the best LCD screens in the world are those of Sharp and Samsung!Didn't Samsung also rely on such spells?People have never taken the wrong path to get some stn screens?

Seeing that Jia Hongjian stopped talking, Ni Guangnan thought for a while and said, "Mr. Jia, I have a few people I know in the liquid crystal field. They are in the Northeast. They have a National Liquid Crystal Research Institute over there, and there is also one in the capital. They are some of the most cutting-edge people in the domestic LCD field. If we want to make TFT screens, we must import them from Japan. If we ask them, they may be able to give us a rough estimate, and we can also predict that we may encounter them after we introduce them. Difficulties……"

"Okay, I'll trouble you, old man!" Jia Hongjian nodded.He didn't believe it anymore, the real development of Samsung in Bangzi Country began in the 80s!Why did Samsung develop so early in 2012?He, Jia Hongjian, didn't say that he was better than Samsung, so why couldn't he be less courageous than Samsung?Samsung can take a gamble even if they don't know the future. Could it be that Jia Hongjian retreated in spite of the difficulties?

After making such a decision, Mr. Ni Guangnan found Jia Hongjian in amazement the next day: "Mr. Jia! An old colleague in the Northeast heard that you wanted to inquire about color LCDs, and said that he would fly today. Come!" Shit?real or fake?He, Jia Hongjian, just wanted to inquire about something, and he didn't want to send money. Why are these old men so enthusiastic?He is not Bai Fumei's sister!

Curious, he saw that it was almost time, so he went to the airport with Ni Guangnan to greet him.After waiting for less than an hour, a gray-haired man shook hands with Ni Guangnan warmly at the exit of the airport. "Mr. Jia, let me introduce you. This is Lao Jiang, Jiang Haichuan, a researcher at the Northeast Institute of Optics and Mechanics of the Chinese Academy of Sciences, and an academician of the Chinese Academy of Sciences. He specializes in liquid crystal and thin film electroluminescence. Lao Jiang, this is our little Mr. Jia... ..."

The gray-haired Uncle Jiang grabbed Jia Hongjian's hand as if he had found a benefactor before Mr. Ni Guangnan finished his introduction, "Oh, you are Mr. Jia? Hello, hello! I heard Are you Huaxia Hi-Tech interested in the color LCD display project? This is a good relationship! Good! It’s great that our country can produce a company like Mr. Jia who is interested in cutting-edge technology!"

kindness?Why did Jia Hongjian always feel as if he was being taken advantage of or treated as a local rich man?It's a bad feeling.Then, on the way to bring Uncle Jiang back to the hotel, the old man was always rambling about Jia Hongjian and Huaxia Hi-Tech. Anyway, it gave Jia Hongjian the feeling that someone finally met someone who was easy to deceive. Rich man, there is a sense of gratitude that the task is about to be completed - of course gratitude to the victim...

This kind of thing happened not only to Jia Hongjian, but also to Ni Guangnan, so when he arrived at the hotel and put down his things, when Uncle Jiang said he was going to see Xiaomi, Mr. Ni said directly—"Old Jiang, tell me, this time What's the matter with you being so enthusiastic?" This Ni Guangnan didn't keep Jia Hongjian at bay, he obviously wanted to get himself out - lest Jia Hongjian think that Ni Guangnan was playing a double play with others to trick him!

"Ah?" Uncle Jiang looked at Ni Guangnan's face and Jia Hongjian's face, and after obviously finding a look of guard and distrust on them, he smiled and slapped his thigh, "Blame me! I didn't know about this. To be clear, it is like this! As for our Institute of Optics and Mechanics, during this period of time, we were discussing with our Jiling Provincial Party Committee and Provincial Government. They said that they saw the rapid development of LCD projects in Japan, and we are going to join forces to build one. The color LCD production base in the north directly serves the Beijing-Tianjin-Tang area in North China. The policy interview has been discussed, but you also know, Lao Ni, that the LCD project, with an investment of tens of millions of dollars, is considered the first This is a real state investment, and the provincial party committee and the provincial government alone can’t come up with so much money! At most, the provincial bank will give us a loan—of course, let us set up a company. But even if the provincial government There are not enough bank loans, and it is estimated that this will cost more than one billion yuan in the end, so we have been looking for a source of funds! Now if Huaxia Hi-Tech is interested, the leaders of our institute will let me come and have a look. Anyway, Huaxia Hi-Tech is also a member of the world's top 500 seeds designated by the state, so it's not impossible for everyone to form a company to research color LCDs!"
