"At present, the liquid crystal display technology on the market is the most Japanese, the Taiwanese also have some unique places in technology, and the Koreans win by cost."

Zhou Shuo, Wang Zhongyang and Huang Shen walked in the quiet corridor of the test building, with a large area of LED energy-saving lamps overhead, and only at the end could you see a wide floor-to-ceiling window. The old locust tree outside the window basks in the sun quietly, occasionally swaying gently in the wind.

Huang Shen said: "The Japanese are said to have achieved 24-inch LCD technology, which is a well-deserved first in the LCD industry. But even so, their best liquid crystal molecule response speed is only 40ms. Mr. Wang's BOE, I don't know how many milliseconds the response speed can be achieved at present? ”

Wang Zhongyang smiled a little embarrassedly, shook his head and said: "Our BOE technology has just started, and it is rare to be able to contact the design of the driver IC." At present, the best response speed is only 108ms, which is certainly not comparable to the Japanese technology. I just don't know how many milliseconds can the technology of Panhan Group achieve a phased breakthrough? ”

Wang Zhongyang fought back slightly, in his opinion, maybe the Fanhan Group can reduce the response speed to 80ms, or close to 60ms. Of course, this is already a good result, and the technology is a little worse than that of the Koreans, but if you work hard, you may be able to have commercial value.

"Mr. Wang can take a look at our products for himself." Huang Shen didn't say the answer directly, but pushed open the door of a research room.

Inside the door, seven or eight researchers in white coats were busy around an LCD monitor on the desk.

This LCD monitor is supposed to be a product of Panasonic Japan. Wang Zhongyang still has an impression of this model. It's just that a good LCD monitor has been dismantled at this time.

Liquid crystal displays can be broadly divided into three parts. One is the most important LCD panel, and the other is the backlight system. The third is to control the circuit.

Liquid crystal display is a technology that does not emit light on its own, and it needs an external light source or natural light as the incident light in order to deflect the light. Therefore, for LCD displays, if you want to display images on LCD panels, you first need to have a back light source system. The deflection of the light emitted by the back light source into a display image is the effect achieved by controlling the magnetic field and controlling the liquid crystal molecules by controlling the circuit.

This monitor is currently divided into three parts according to these three parts, and it is being tested.

When the researchers in the room saw Huang Shen and Zhou Shuo, they all said hello. Then he continued to devote himself to the experiment without raising his head.

Huang Shen didn't disturb their work, but opened a small door that led to the inner room on the side. This is a transparent glass door, and there is a small real room with a space of more than 20 square meters in the door. After Zhou Shuo took Wang Zhongyang in, he saw that there was a slightly rough monitor with no obvious sign on the real platform in the middle of the inner room.

"This is a prototype that we procured some of the accessories on the market by ourselves, and then used the driver IC we developed ourselves, and finally assembled them into a prototype."

As Huang Shen spoke, he kept turning on the power of the equipment in his hand, and the preparation of several test instruments was quickly ready.

"You're using a Panasonic panel, right?" Wang Zhongyang is more or less knowledgeable. At a glance, you can see the technology used by Pan Han Group.

"Did you remove the driver IC from the Panasonic panel and replace it with your own?"

"Not only that, but our main control board has also been modified to accommodate the new technology we use in the driver IC." Huang Shen glanced out. Pointing to the dismantled LCD outside, he said, "If Mr. Wang is interested, you can take a look at the test product used for testing." There are a lot of small places that need to be paid attention to on the main control circuit board, so let's not talk about them for the time being. ”

"Good. Let me see your technology. Wang Zhongyang rubbed his hands a little excitedly.

Taking advantage of Huang Shen's time to operate the equipment, Wang Zhongyang still couldn't help but ask Zhou Shuo: "Mr. Zhou." Tell me the truth, can your LCD response time reach the level of Koreans? ”

"Koreans?" Zhou Shuo laughed and said, "Our target is the Japanese. Responsiveness is a major obstacle to LCD displays replacing CTR displays, and South Koreans currently have little say in this area. ”

Unlike more than ten years later, South Korea's Samsung dominated the field of consumer electronics, although Samsung is already a powerful multinational company, but there is really no turn for him to speak in the market. In the nineties, the microelectronics industry, that belonged to the Japanese. Whether it's chip manufacturing or liquid crystal displays, Koreans are two streets away from the Japanese.

To put it bluntly, the Japanese are a dog of the Americans, and in the early years this dog was used to defend against the Soviet Union and China, so of course it had to be fed. However, after the collapse of the Soviet Union in the 90s, Japan's importance declined dramatically. South Korea is at the forefront of the confrontation with China, naturally because China's rise is becoming more and more important to the United States.

Japan's declining importance can't stop Mei Papa's several sheep shearing actions. And the rise of the Koreans is also inseparable from the strong support of the Americans. At least in 1996, China was still wearing the skin of a harmless white rabbit, and South Korea's support for Cheng Dù was not so high.

Zhou Shuo knows this trend in the future, and the rise of South Korea lies not only in South Korea itself, but also in the support of the United States. At this time, it is relatively safe to attack Japan.

Disguising himself as an American to smash the Japanese field is Zhou Shuo's favorite thing to do.

The two of them said a few words, and Huang Shen was ready to start the test equipment for the test.

Wang Zhongyang hurriedly ended his conversation with Zhou Shuo and stared at the LCD screen with full attention. On the top of the screen, the images of various tests flashed. Because of the response speed of the test monitor, these test images change very quickly, and even make people feel dizzy.

"Mr. Zhou, you ......"

Wang Zhongyang just stared at it for a while, and then he felt a little dizzy. This was the case with early computer image processing technology, and poor 3D effects could even turn people around.

However, Wang Zhongyang's bad face was not because of the dizziness in his mind, but because he had an answer in his heart and couldn't make up his mind.

He closed his eyes for a moment before standing firm and asked incredulously, "The response speed of this monitor has exceeded 20ms?" ”

Wang Zhongyang asked a level, why did he ask if it exceeded 20ms? Because that's the limit of how responsive the display is to the human eye. In fact, he is asking whether the driver IC technology of Panhan Group has the conditions for market promotion in terms of response speed.

Once the response speed of the display exceeds the 20ms boundary, it doesn't make much sense to be fast. Because whether it is a response speed of 19ms or a display speed of 1ms, there is no impact on normal use.

“5ms。” Zhou Shuo stretched out five fingers and nodded with a smile.

Wang Zhongyang's mouth was open enough to put a fist in it.

5ms, which is one-eighth of the technical indicator of the Japanese, but this does not yet say anything about the significance of this figure. What does it mean for an LCD monitor to reach 5ms response speed?

Wang Zhongyang knows in his heart that this means that the current research on the response speed of liquid crystal displays can be suspended. The CRT display on the market does not have the concept of response time, because the CRT display itself is an electron beam hitting the phosphor screen to emit light, rather than deflecting the light of the light source, so its so-called "response time" is meaningless at all. Barely to say, that is, the afterglow time indicator is similar.

But why is it that no one ever hyped this afterglow time for CRT displays? Because the human eye itself also has an "afterglow time", that is, a visual persistence mechanism. Visual persistence is easy to understand, for example, if you look at the sun, even if you close your eyes immediately, there will be a silhouette of the sun left in your eyes. This remnant outline of the sun is the visual retention of human beings.

A medium-intensity luminosity stimulus stays in the human eye for 50ms. Even for the weakest brightness stimuli, the visual persistence will not be less than 5ms.

Therefore, as long as the response speed of the LCD can reach 5ms, the application needs of ordinary people can be fully met.

"This, but I don't know what solution you used, Mr. Zhou?" Wang Zhongyang asked a little weak-hearted, no way, this is definitely the core technology. BOE has been giving the Japanese a hand for so many years, isn't it because of the lack of core technology? I am afraid that this kind of important trade secret will not be revealed lightly.

"Mr. Wang should have heard such an idiom, which is called overkill." Zhou Shuo did not answer his question directly, but asked him a literary question.

"Of course I've heard it, but I don't know what it has to do with the response time of the LCD?" Wang Zhongyang asked in confusion.

Zhou Shuo said with a smile: "According to the research of the Pan Han Research Institute, the speed of deflection of liquid crystal molecules is directly proportional to the voltage loaded. The higher the loaded voltage, the faster it will be deflected. ”

"Ahh Wang Zhongyang's eyes lit up, and then he was puzzled: "But in this way, the deflection angle of the liquid crystal molecule will be too large, and it will not be able to correct the color of reality, right?" ”

"When the liquid crystal molecules are about to move into place, apply a reverse stance to counteract the excessive deflection angle." Zhou Shuo smiled and said lightly.

"No wonder ......" Wang Zhongyang heard Zhou Shuo's explanation, and suddenly understood why he would reveal such an important technical secret to himself without care. (To be continued......)
