Chapter 175 (2/2)
”I believe you have a way. If you can come here, it naturally shows that you have the ability to cooperate.” Liu Chi's heart is like a mirror!
”If you don't have this ability, we can't continue our cooperation, right?”
”I'll think about it. How about getting back to you in a few days. ” Ed thought for more than ten seconds and finally said.
”No problem. I'll wait for your good news.” Liu Chi nodded.
“……”
After Liu Chi sent the people away, he came to the laboratory.
”How's it going? Have you got an idea? ” Liu Chi looked at the serious Zhou Meng and asked.
”Brother Chi, are you here?” When Zhou Meng finished, he found himself talking nonsense. He was busy changing the topic and pointed to the computer screen: ”this is the data I sorted out and my design scheme.”
”Tell me?” Liu Chi looked at the screen in front of Zhou Meng and asked.
”I want to directly improve the plasma screen technology. The ion screen is a device that injects mixed gas between two ultra-thin glass plates, applies voltage, and uses phosphor to emit light and image.”
”I want to add an electro-ionic layer on the basis of it, that is, add a bile permeable substrate at the bottom to support imaging technology.”
”That's a good idea, but how do you make it transparent? How to produce imaging technology? ” Liu Chi touched his chin and asked suspiciously.
”The coating behind is changed to CRT special coating. CRT coating is completely transparent and produces negative oxygen ions through the combination of light.”
Zhou Meng then explained, ”if the negative oxygen ions in the normal fresh air are 200 per 1000cc.”
”When the non negative oxygen ion display works, the content is 40 ~ 48. When the negative oxygen ion display works, the content is 114 ~ 139. If we turn off the display, the number can reach 280.”
”Because of the material problem of the shell, the influence of PCB and high voltage, the display will offset part of the negative oxygen ions produced by CRT, so it can fully meet our technical requirements.”
”What about the strength of the screen? How to solve the waterproof problem? You know, this screen is to be spliced. ”
”I can't solve the problem of waterproof.” Zhou Meng scratched his head and said helplessly, ”there is also a transparent one. I don't know what to do about the splicing problem.”
”Because it's transparent, it's clear that you can see the back, there's no way to install lines, etc. if you see the lines behind the glass, the advantage of transparency can't even compare with that of opacity.”
”...” Liu Chi thought that it was really the same thing.
It's not ugly to see the inner line from the outside!
”Brother Chi, do you have a way?”
”The transparent ones can be made into small non spliced ones. Compared with windows and glass doors, the lines can be installed on the metal frame, and the spliced ones can be made into one-way transparent.” Liu Chi thought for more than ten seconds and came to a medium discount scheme.
”It seems OK. After all, the floor to ceiling window also needs to be fixed with a support. If it is one-way glass, we can't see the support inside from the outside. We can install the line on the support.” Zhou Meng's eyes lit up.
”That's the problem of waterproof.” Zhou Meng said a little rogue, ”brother Chi, I'll give it to you.”
”Yes, I'll find a way.”
......
Liu Chi looked at the special Zhou Meng, shook and walked to the laboratory!
Waterproof?
There seems to be no way for the time being.
Back to the office!
Liu Chi leaned back on the boss's chair and meditated.
The only way is the material!
The whole French window was spliced with tens of pieces less and hundreds of thousands more. The interlayer could only be sealed with materials. Liu Chi thought for a long time. Finally, he could only smile bitterly and shake his head.
It's not generally difficult!
Now outdoor LED lamps are waterproof, and many of them work on the waterproof box structure of LED display screen;
Start to develop to light, thin and easy to disassemble box;
However, from a professional point of view, it is not necessarily waterproof if it is completely closed and light. The box structure only plays the role of dust prevention and foreign matter prevention.
The space is small, which is not convenient for heat dissipation, and if there is water in a large area, it is not conducive to treatment and maintenance.
Rain, fog and other weather effects often occur outdoors;
Therefore, the outdoor LED module and closed box structure are processed to form the LED outdoor display box, and then the box is assembled into the outdoor LED full-color display.
Therefore, the LED display box is the basic unit constituting the display body.
wait!!!
Why not use physical refraction technology?
If electrons are obliquely injected from one transparent medium into another, the propagation direction will generally change.
Refraction, like light reflection, occurs at the junction of two media;
Only the reflection returns to the original medium, while the refracted light enters another medium, because the light travels at different speeds in two different substances.
It is suitable for homogeneous isotropic media.
？？？
According to: refraction law;
When light is refracted through the interface of two media, the law determining the relationship between the propagation direction of incident light and refracted light is one of the basic laws of geometric optics.
The plane formed by the incident light and the interface normal passing through the incident point is called the incident plane, and the included angle between the incident light and the refracted light and the normal is called the incident angle and the refraction angle respectively θ I and θ T indicates.
The refraction law is:
① Refracted light is in the incident plane.
② The sine ratio of the incident angle and the refraction angle is a constant, expressed by N21, i.e
sin θ isin θ t=n21
sin θ isin θ t=v1v2=n21
Where N21 is called the relative refractive index of the second medium to the first medium.
The law that the cosecant ratio of incident angle to refraction angle is a constant;
Namely
csc θ icsc θ T = constant
Therefore, the law of refraction is also called Snell's law.
The refraction law is only applicable to the static interface composed of isotropic media.
So!!!
Therefore, the propagation direction changes at the junction of the two media, which can achieve 0.0mm seamless splicing.
Add a waterproof groove, that should be no problem!
I have to try!
Liu Chi directly opens the computer in front of him and looks for relevant information.
......
A week later.
Laboratory building assembly workshop.
”How's it going?” Zhou Meng stretched out his neck, looked at the large screen connected by four 1000X1000mm screens in Liu Chi's hand, and asked.
”I can't see the problem for the time being.” Liu Chi put the newly spliced screen and said to Zhou Meng, ”open it and have a look?”
”Good!” Zhou Meng directly turned the notebook on the table and said, ”it's starting?”
”Yes!”
”Pa...” just as Liu Chi's words fell, Zhou Mengzhong gently tapped the Enter key.
In half a minute.
？
？？
Zhou Meng has a question mark all over his face.
Why doesn't the screen respond?
Liu Chi also looked strangely at the dark screen, turned around twice, carefully checked the line problem, and finally shook his head to Zhou Meng.
Doesn't make sense?
Not to mention the pattern, it doesn't light up now.
”Turn it off first. You have to take it out and have a look.” Finally, Liu Chi, who couldn't find the problem, had to give up temporarily and open it up for another inspection.
”Yes!” Zhou Meng answered and turned off the power generation device.
In two hours!
”Zhou Meng, do you think you can't clip it into materials?” Liu Chi scratched his forehead.
”I don't think so. I use plasma phosphor luminescence imaging technology. Is this a very mature technology? It doesn't make sense. ”
”I mean the coating on the back of you.”
”Uh?” Zhou Meng was stunned and finally said, ”should there be no problem?”
”Are there any more samples? Take the sample and test it on the tester. ”
”Yes, I'll get it.” Zhou Meng puts the notebook in Tian's hand and runs out of the workshop.
