Chapter 166 Developing Displays
Li Sanbiao knows that this is a common problem in inferior LCD display. If he wants to make high -quality products, he must solve it.
Calling artificial intelligence: "Three uncle, what's the matter?"
"Ding! The boss can use the super twisting double refraction effect of the LCD molecule to use the super twist to the column phase LCD display technology, so that the liquid crystal molecule can be reversed to 180 degrees to 270 degrees to improve the problem of the display perspective!"
It turns out that this is the case! Li Sanbiao has been solved for many years, and immediately told the chief worker about this new knowledge, and gave the basic technical structure.
Three days later, the new technology of 774 was successfully developed, and used it on the calculator screen, and the widescreen LCD screen in their experiments.
The wide -screen LCD screen is still a two -color display. At the request of Li Sanbiao, the 774 factory did not release them.
Because now throughout the country, TV machine plants are built in fast horses and whipped. Every year, 30 or 40 projects are launched.
Although television is often out of stock in the mall and is still in the shortage economy, Li Sanbiao knows that it will soon become an excess economy.
If Li Sanbiao is going to insert a kick at this time, it will undoubtedly make the future worse. In many places, the TV machine factory that borrows money will not be charged, and the money will be drifted.
So Li Sanbiao will not make such money.
However, Li Sanbiao still kept the liquid crystal of the 774 factory kept in research and development, and gave some tips to let the 774 factory close the color LCD technology.
The color filter plate is added to the color, and the brightness of the liquid crystal unit is controlled by the voltage.
It sounds like colorful fish black and white is not much different, but in fact it represents the great progress of the chip calculation.
This voltage control, decoding the image signal, must also have powerful storage and computing power in order to convert the image into a dot matrix, and then change the voltage of each point of each point of the filter.
There is no corresponding display chip, it is impossible.
Li Sanbiao told them the principle, leaving a programmer to help them perform control programs, allowing the participation of chip business to participate in the research and development, encouraged the 774 joint 878 factory, developed the filter board and display chip by themselves.
As for the traditional flat display, the same principle as the TV,
It was originally a backward product in Li Sanbiao's eyes, and there is no need to develop.
However, he feels that the computer is relatively hot now, and the profit of the display is not low, so you can't let it go, so you have to make a small amount in this area.
The 774 factory is called the four -nine city electronic pipe factory. The production vacuum tube is the main business. It also includes a military imaging tube, but the production line is not formed.
The first domestic black and white image pipe production line independently developed in China was produced in the Sichuan Province Hongguang Electronics Plant in 1983. This is a large electronics factory of the aviation department.
At the end of 1982, the colorful image pipe factory of Shaanxi Province will also be put into operation, but this factory uses Toyo technology.
The reason why Dragon State's appearance is slowly progressing because the "snail incident" in 1973.
In fact, at that time, the Dragon Kingdom intends to introduce technology from Corning Company of a beautiful country, and sent a delegation to inspect.
However, Corning did not know what considerations, and gave the delegation a glass snail of each person. After returning to China, there was an uproar, and the introduction of what was introduced.
Li Sanbiao heard that they also wanted to engage in a color TV production line and persuaded; "According to my opinion, the domestic color TV domestic is definitely excess, but you can improve the technology and produce a colorful display display."
774 Director of the factory depressed; "We have black and white image pipe technology, but the technology of colored imaging tube has not made breakthroughs."
Li Sanbiao asked the reason and found that this technology is difficult to solve.
At that time, the colorful appearance was high -tech, only a few Toyo manufacturers such as the winter solstice, Hitachi, Panasonic, etc. Although it was sold to the Longguo production line, it was only assembled.
Li.
Although Longguo adopted a strategy of using technology to change the market, the other party only gave some ordinary craftsmanship perfunctory, and high -end techniques such as Tri Long did not give it at all, and they still sold the appearance tube to the Dragon State.
And the price of the imaging tube accounted for half of the cost. Although there are many domestic TV machine plants, they are basically working for Toyo manufacturers.
Although Li Sanbiao did not intend to join the TV war, the see -through war war still has to participate.
After the CRT technology is gradually eliminated, these technologies have been obtained by some second -line manufacturers. They use their remaining value and have low prices to rural production and sell for a period of 21 -inch appearance tube TV.
At this time, there are no secrets in these technologies, so the three uncle has a full set of related technical information.
Li Sanbiao gave these technical points inadvertently to the chief and technical staff of the 774 factory.
After receiving the color TV signal, the color imaging tube is pressed by red, green, and blue three -base signals, controlling red, green, and blue.
The electron beam is affected by the deflection magnetic field, allowing the electronic beam from left to right, scanning from top to bottom, and a picture of image.
The colorful sight is to allow the electronic beam to pass a component called the shade. It has a steel plate with a lot of small holes. Through its cover, the three electron beams can accurately hit the corresponding color on the screen.
The fluorescent powder bars will not be hit in other places.
The core part of the shade cover is the shadow mesh, which has the role of color selection, as well as dual metal springs, heat -up compensation effect, and supporting component framework.
The shadow cover must be annealing, stamping molding, blackening and other processes, that is, on the surface of the shadow cover and the surface of the frame, a dense Fe3O4 black film is formed. The membrane thickness is about 2.7 microns to 3.0 microns. Therefore, the imaging tube looks dark.
And fluorescent screens, components are glass screens, black -bottom graphite, three -color fluorescent powder, aluminum film.
The manufacturing method is to apply the three -color fluorescent powder bars arranged red, green, and blue in the inside surface of the glass screen, and then steam the aluminum layer.
Inside, the fluorescent screen needs to be exposed, there are many technical details.
These are very mature technologies later, and you can find the information that can be operated. Li Sanbiao provided it to the 774 factory.
The 774 factory is actually missing some technical details. The performance of the displayed pipes is not good, and the color is uneven. After getting the guidance of Li Sanbiao, immediately realize it.
Two days later, it was made into a technical advanced Sirilong imaging tube, reaching the world's leading level.
After the technology is set, it can be manufactured in batches.
However, what exactly does the production line look like, the three grandfathers can't say it.
Li Sanbiao came up with an idea to ask the 774 factory to open a letter of introduction to himself. In the name of visiting and learning, he went to the Shaanxi Provincial Vegetable Plant to take some photos of the Toyo Midth Magazine Production Line.
