Chapter 9: Solving technical obstacles
Without mentioning the person in charge of the venue was worried, Fan Wubing easily got rid of the group of security guards and continued to follow the old man and the others in the venue.
Seeing that Fan Wubing met the new district mayor and his person in charge had just been defeated, the security guards naturally scattered. Anyway, they were all minions, so there was no need to make trouble with him here.
Xiao Qiang asked Fan Wubing in a low voice, "Wubing, why are you so brave? This is an international venue! We didn't dare to speak loudly, you just kicked the stage-"
Fan Wubing smiled and said, "Sister-in-law, I am just brave, not only dare to think, but also dare to do it."
Xiao Qiang snorted, "Don't scream."
"By the way, sister-in-law. What are your brother doing recently?" Fan Wubing suddenly remembered this matter and asked casually.
"I'm going to college in Beijing." Xiao Qiang replied.
Oh, Fan Wubing shook his head. Time flies so fast. When he first met Xiao Guizhi, he seemed to have just been in junior high school. He went to the United States by himself. After nearly two years of coming back, he happened to be in college.
So Fan Wubing asked, "Which university? What major are you studying?"
"Well, I'm at Beijing Film Academy and studying the director major." Xiao Qiang talked about this and had a headache and complained to Fan Wubing, "It's very expensive to study that major. I don't know where he got so much money from. He secretly ran to Beijing and got into Beijing Film Academy and Wubing. Do you think you have a future in the future when studying the director major?"
"The future is very bright--" Fan Wubing replied solemnly.
Although the domestic film industry is at a low point now, it is basically dominated by the so-called fifth-generation directors. However, a few years later, with the rise of the Internet, it is not the official directors who have the final say.
Even if we can handle the Radio, Film and Television Bureau and Propaganda Department and use some unscrupulous films to fool the audience, the wisdom and appreciation level of the general public will not always be at the level of being able to play with others. As long as we have the strength and want to make a name for ourselves in the future, Xiao Guizhi still has hope.
Especially, he is a friend that Fan Wubing made since childhood. With Fan Wubing, a tycoon in the entertainment industry, he still has to worry about not being able to find a way out?
Fan Wubing has even considered it, so he first found Xiao Guizhi, gave him a notebook, and made a film that could win awards, and made a fame in the school, killing the aura of the royal directors.
The old man is a knowledgeable research talent and can speak several foreign languages. Many of these foreigners have dealt with, so they talked about one thing and exchanged some experiences on their own. Of course, the key things must be kept confidential.
In theory, although some things can be done, if there are no correct experimental steps, it will be useless. It is like you know that Americans rely on space shuttles to the moon, but how to build this space shuttle is not a matter of one or two days.
Fan Wubing also noticed that Zhang Ruixi suddenly disappeared during this moment.
"She ran so fast--" Fan Wubing nodded, knowing that the agents must have made it very strict. In fact, she had asked Xiao Qiang to install the tracker into Zhang Ruixi's button yesterday, and she couldn't escape no matter how hard she ran.
In addition to the papers released throughout the display event, there are also samples provided by certain research rooms and the latest commercial products of LCD technology.
In fact, the main applications of LCD technology now include LCD projectors, some game consoles, portable computers, electronic devices, or mobile phone screens.
The products provided at this exhibition are mainly LCD projectors.
From a technical perspective, the rise of LCD projectors is mainly the development of LCD, an extremely critical component of internal components. Due to the large number of applications of laptop computers and portable CD Walkman, LCD is valued and the technology is gradually mature.
Originally, large-screen projection was the most common to the use of traditional CRT-type triple-gun projectors. However, after 1990, due to the breakthrough of the mass production technology of LCD, the resolution and brightness increased significantly. The quality of natural LCD projectors far exceeded that of CRT-type triple-gun projectors, and thus became the mainstream of large-size displays.
Simply put, the LCD projector can be deconstructed into an optical system, LCD LCD module and electronics. Among them, the optical system is not only complex, but also involves a wide range of technical aspects and categories, including optical specification measurement, optical system architecture, optical design, light source module, split-and-combination optical components, projection lens and screen. As for the LCD LCD module, it is a device that controls the projector to display images, mainly considering the RGB element arrangement, liquid crystal characteristics, etc., including the common silicon crystal TFT, that is, thin-film transistor process technology, which has a direct impact on image resolution. The final electronic part is to process the input electronic image signal, and then the color electronic signal to be displayed is transmitted to the LCD LCD module.
The basic principle of liquid crystal projection is to use the lcd liquid crystal module to adjust the color light projected onto the screen from the light source. In order to accurately project the color of the image, it is necessary to separate the color of the light source into three colors r, g, and b, and then combine it into one and projected on the screen using a projection lens.
"The biggest problem restricting the development of LCD projectors is the first problem of brightness, and secondly color reduction." Fan Kang has been studying LCD technology for several years and is quite familiar with these things, but after all, he was on the shelves and learned this with Xiao Qiang, so he is naturally much less than Xiao Qiang in theory.
"Japan is better at handling this aspect. They are much ahead of us in the development of LCD technology." Xiao Qiang said to Fan Wubing.
Fan Wubing nodded and said, "The Japanese have always worked hard in these aspects. Although I don't like them, I have to admit that they still have two tricks."
Similarly, there are some LCD technology applied to laptop screens in the display, but the visual angle, response time and manufacturing cost of LCD displays are now recognized as three major obstacles to LCD technology.
Whether in terms of production costs or display results, the quality of the LCD panel is a key factor in determining whether a LCD display is excellent. Currently, the LCD panel is mainly produced by Japanese and Korean manufacturers, and mainstream technology is firmly controlled by them.
However, the overall brightness of the LCD panel at this time is not high. The projector and laptop use LCD technology, not only the power consumption is large, but the power supply must be increased to increase the brightness, so heat dissipation is also a big problem. After all, if the heat generation is too high, it will have a great impact on the life of the body and also limit the use environment.
"The technical content of the projector is not very high. The key is how to solve the light transmittance problem of the LCD panel? Once this problem is solved, the bottleneck limiting its use will be broken, and the application scope of the product can also be expanded." Xiao Qiang said to Fan Wubing.
Oh, Fan Wubing nodded. He probably encountered this problem when he was watching videos in college in his previous life. When watching videos during the day, he needed to pull up all the thick curtains on the windows so that he could see better results. Once there was exposure, the screen would be blurred.
But in the next few years, even if the projection was placed in the hall with the lights on, it could be seen very clearly. This probably solved the problem of the so-called light transmittance of the LCD panel.
Thinking of this, Fan Wubing seemed to have thought of a technical problem I saw at the beginning, which was about increasing the brightness of the LCD panel, so he said, "I seem to know how to solve this problem, but how to implement it depends on your technical level that is not up to standard."
"Really? Don't breathe heavily when you speak." Fan Kang asked with some doubts.
"Of course it's true!" Fan Wubing immediately replied with some dissatisfaction.
In fact, Fan Wubing has indeed read articles about this, but he is not a professional and technical person and does not know the feasibility of this kind of thing, so he told Fan Kang and Xiao Qiang what he knew.
The solution is actually very simple. There is a grid in the LCD panel of the projector. When light passes through the grid, it will inevitably be hindered, which will affect the light transmittance. Therefore, the brightness is affected. If you want to increase the brightness, you must increase the input power, and the effect is not very good.
Fan Wubing’s method is to add a microlens layer behind the grid, and then the light passes through the microlens and then focuses through the grid. In this way, the loss of light will be minimized. The brightness of the LCD panel can naturally be greatly improved without increasing power.
After listening to Fan Wubing's explanation, the two of them were stunned.
Fan Wubing asked embarrassedly, "What's wrong? Is this solution not working?"
"It's not that it's not possible, but we have never considered solving this problem from the perspective of non-LCD technology. Alas, with this idea, I believe that the latest energy-saving projector will be launched soon. If it is put into commercial use, the market share will definitely be large!" Fan Kang shook his head and replied, "It's hard to believe how you thought of it?"
"Nonsense! All science and technology come from life!" Fan Wubing retorted, "If your brother is not that genius, where did you earn so much money?"
"Don't mention this. I think we should communicate with the tutor first. There is no need to continue this meeting. It is true that this experiment is implemented." Fan Kang discussed with Xiao Qiang and unified his thoughts.
The old man was also impatient. When he heard Fan Kang and Xiao Qiang talk about this method, he slapped his head and left immediately with the two of them. He probably wanted to book a plane ticket directly back to Tianjin.
