Chapter 9 Solving Technical Obstacles
Not to mention that the person in charge of the venue was worried, but Fan Wubing easily got rid of the group of security guards, and continued to follow the old man and the others around the venue.
Seeing that Fan Wubing got acquainted with the new district chief, and his person-in-charge had just been beaten, the security guards naturally dispersed. Anyway, they are all young people, so there is no need to make a fuss here.
Xiao Qiang asked Fan Wubing in a low voice, "Wubing, why are you so courageous? This is an international venue! We dare not speak loudly, so you just kicked the floor——
Fan Wubing said with a chuckle, "Sister-in-law, your little uncle and I are very courageous, not only dare to think, but also dare to do."
Xiao Qiang snorted, "Don't bark."
"By the way, sister-in-law. What is your brother doing recently?" Fan Wubing suddenly remembered this matter, so he asked casually.
"I'm going to university in Beijing." Xiao Qiang replied.
Oh, Fan Wubing shook his head, time flies so fast, when he first met Xiao Guizhi, he seemed to be in junior high school, he went to the United States for a trip, and it took nearly two years after he came back. Well, he happened to be in college.
So Fan Wubing asked, "Which university? What major are you studying?"
"Well, I studied directing at Beijing Film Academy." Xiao Qiang had a headache when she talked about this, and complained to Fan Wubing, "It's very expensive to study that major, and I don't know where he got it himself. With so much money, I sneaked to Beijing and was admitted to Beijing Film Academy without any illness. Do you think you will have a future if you study directing?"
"The future is very bright—" Fan Wubing replied solemnly.
Although the domestic film industry is at a low ebb now. Basically, the world is dominated by the so-called fifth-generation directors. But after a few years. With the gradual rise of the Internet. But it's not that these queen directors have the final say.
Even if it can handle the Bureau of Radio, Film and Television and the Propaganda Department. Use some unintelligible bad movies to fool the audience. But the wisdom and appreciation level of the broad masses of the people. It is impossible to stay at the level of being manipulated forever. As long as there is strength. I want to get ahead in the future. Xiao Guizhi still has hope.
especially. He was Fan Wubing's friend since childhood. There is Fan Wubing, a tycoon in the entertainment industry. Still worry about not finding the way to get ahead?
Fan Wubing had even considered it. Find Xiao Guizhi first. Give him a notebook. Make an award-winning film. Get famous in school. Kill the vigor of those queen directors.
The old man is a erudite research talent.
There are several foreign languages. Among these foreign devils. There are also many places where I have dealt with. So they talked about one place. Share some experiences with each other. Of course. The key things should still be kept secret.
In theory though some things can be done. But if the experimental procedures are not correct. That's also useless. It's like you know that Americans rely on space shuttles to get to the moon. But how should this space shuttle be built. It's not a matter of a day or two.
Fan Wubing also noticed that Zhang Ruixi suddenly disappeared within this short period of time.
"She runs really fast—" Fan Wubing nodded. I knew that the agents must be very strict. In fact, I had Xiao Qiang put the tracker into Zhang Ruixi's button yesterday, and she couldn't get away no matter how she ran.
In addition to papers, there are also samples provided by some research laboratories and the latest commercial products of liquid crystal technology in the entire exhibition.
In fact, the main applications of liquid crystal technology are mainly liquid crystal projectors, some game consoles, portable computers, and electronic equipment. Or more on the phone screen.
The products offered at this exhibition are mainly LCD projectors.
From a technical point of view, the rise of LCD projectors is mainly due to the development of a very key internal component, d. Because of the large number of applications of notebook computers and portable CD players, d has been valued and the technology has gradually matured.
Originally, the traditional cRT-type three-gun projector was the most used for large-screen projection, but after 1990, a breakthrough was made due to the mass production technology of d. Both resolution and brightness have been greatly increased. Naturally, the quality of LCD projectors far exceeds that of cRT-type three-gun projectors, and has become the mainstream of large-size displays.
simply put. Liquid crystal projectors can be roughly deconstructed into three parts: optical system, liquid crystal module and electronics. The optical system is not only complicated, but also involves a wide range of technical levels and categories, including optical specification measurement, optical system architecture, optical design, and light source module. Group, split light components, projection lens and screen, etc. As for the d liquid crystal module, it is a device that controls the image displayed by the projector. The main considerations are the arrangement of RgB picture elements, liquid crystal characteristics, etc., including the common silicon crystal TFT or 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 transmit the electronic signal of the color to be displayed to the bsp; the basic principle of liquid crystal projection is to use the d liquid crystal module to modulate the color light projected from the light source to the screen, In order to accurately project the color of the image, it is necessary to separate the color of the light source into three colors of R, g, and B, and then merge them into one and project it on the screen with a projection lens.
"The biggest problem restricting the development of LCD projectors is the brightness problem first, and the color reproduction problem second." Fan Kang has studied liquid crystal technology for several years, and he has a good understanding of these things, but after all, he is rushing ducks to the shelves. , Those who followed Xiao Qiang to learn this are naturally not as good as Xiao Qiang in theory.
"This aspect is handled better by Japan. They are far ahead of us in liquid crystal technology." Xiao Qiang said to Fan Wubing. Fan Wubing nodded and said, "The Japanese have always worked hard in these areas. Although I don't like them, I have to admit that they still have two talents."
Similarly, there are some liquid crystal technologies applied to notebook computer screens in the display, but the viewing angle, response time and manufacturing cost of liquid crystal displays are now recognized bsp; no matter in terms of production cost or display effect, d-panel The quality of the display is a key factor in determining whether the performance of an LCD display is excellent. At present, d-panels are mainly produced by Japanese and Korean manufacturers, and the mainstream technology is also firmly controlled by them.
However, the brightness of the LCD panel at this time is not high as a whole. Projectors and laptops use 3D technology, which consumes a lot of power. If you want to increase the brightness, you must increase the power supply, so heat dissipation is also a big problem. After all If the heat is too high, it will also have a great impact on the life of the body, and also limit the use of the environment.
"The technical content of the projector is not very high. The key is how to solve the light transmittance problem of the d-panel? Once this problem is solved, the bottleneck restricting its use will be broken, and the application range of the product can also be expanded." Xiao Qiang Said to Fan Wubing.
Oh, Fan Wubing nodded. He probably encountered this kind of problem when he was watching a video in college in his previous life. To watch a video during the day, he had to close all the thick curtains on the windows. In order to be able to see better results, once there is a phenomenon of light loss, the screen will be blurred.
But in the next few years, even if the projector is placed in the hall with lights on, it can be seen very clearly. This probably solved the so-called bsp; thinking of this, Fan Wubing seemed to think of a technology he had seen before. The problem was about increasing the brightness of the d-panel, so he said, "I seem to know how to solve this problem, but how to achieve it depends on your technical level."
"Really? Don't gasp when you speak." Fan Kang asked suspiciously.
"Of course it is true!" Fan Wubing immediately replied with some dissatisfaction.
In fact, Fan Wubing did read articles about this, but he is not a professional technician, so he didn't 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 the light passes through the grid, it will inevitably be hindered, which also affects the light transmittance, so the brightness is affected. To increase the brightness, you have to increase the input power, and the effect is not very good.
Fan Wubing's solution is to add a layer of microlenses behind the grid. The light passes through the microlenses and then focuses through the grid. In this way, the loss of light is reduced to the minimum, and the brightness of the d-panel can naturally be at It has been greatly improved without increasing the power.
After hearing Fan Wubing's explanation, the two of them were stunned.
Fan Wubing asked with some embarrassment, "What's the matter? Doesn't this method work?"
"It's not impossible, but we have never considered solving this problem from non-liquid crystal technology. Alas, with this idea, I believe that the latest energy-saving projector will be launched soon. If it is put into commercial use, it will occupy a large market share." The rate must be huge!" 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 such a genius, where did you get so much money?"
"Don't mention this matter. I think we should communicate with the instructor first. There is no need to continue this meeting. It will be true if this experiment is implemented." Fan Kang discussed with Xiao Qiang and agreed thinking.
The old man was also impatient. After hearing Fan Kang and Xiao Qiang talk about this method at first, he slapped his head and left immediately with the two of them. He probably planned to book a plane ticket back to Tianjin directly.
It's just that Zhang Ruixi didn't know where she went, so Fan Wubing stayed at the venue and waited for her to come back.
