Zhou Meng then went on to explain: "If the negative oxygen ions in normal fresh air are 200 per 1000CC."
"When the non-negative oxygen ion display is working, the content is 40~48, when the display is working with negative oxygen ions, the content is 114~139, and if we turn off the display, the number can reach 280."
"Because of the material of the display's casing, the influence of the PCB board and high voltage, some of the negative oxygen ions produced by the CRT will be offset, so it can fully meet our technical requirements."
"What about the strength of the screen? And how to solve the waterproof problem? You know, this screen needs to be spliced."
"I can't solve the waterproofing problem." Zhou Meng scratched his head helplessly and said, "Also, if it's made transparent, I don't know how to solve the splicing problem."
"Because it's transparent, you can see behind it, and it's impossible to install wiring, etc. If you can see the wiring behind the glass, then the advantage of transparent glass is not even as good as that of opaque glass."
"......" Liu Chi thought about it and it seemed to be true.
Seeing the inner line from the outside is so ugly!
"Brother Chi, do you have any solution?"
"Then the transparent ones can be made into small ones without splicing, such as windows and glass doors. The lines can be installed on the metal frame and spliced to make it one-way transparent." Liu Chi thought for more than ten seconds and came up with a compromise plan.
"It seems possible. After all, floor-to-ceiling windows also need to be fixed with brackets. If it is one-way glass, the brackets inside cannot be seen from the outside. We can install the wires on the brackets." Zhou Meng's eyes lit up.
"The only problem left is waterproofing." Zhou Meng said in a somewhat rogue manner, "Brother Chi, I'll leave it to you now."
"Okay, I'll figure it out."
......
Liu Chi looked at Zhou Meng, shook his head and walked to the laboratory!
water proof?
It seems there is no solution for now.
Back to the office!
Liu Chi leaned back in his boss chair and began to ponder.
The only way is the material!
The entire floor-to-ceiling window is made up of hundreds or thousands of pieces, at most dozens. The only thing to do is to seal the interlayer with materials. Liu Chi thought about it for a long time, and finally could only smile bitterly and shook his head.
It’s extremely difficult!
Nowadays, outdoor LED lights are waterproof, and many efforts are made on the waterproof box structure of the LED display;
Started to develop towards thin and light, easy-to-disassemble boxes;
But from a professional perspective, being fully enclosed and thin does not necessarily mean it is waterproof. The box structure only serves to prevent dust and foreign matter.
The small space makes it difficult to dissipate heat, and if water enters a large area, it will be difficult to handle and repair.
Outdoors are often affected by weather such as rain and fog;
Therefore, the outdoor LED module plus the closed box structure is processed to form an LED outdoor display box, and then the box is assembled into an outdoor LED full-color display.
Therefore, the LED display cabinet is the basic unit that makes up the display body.
etc! ! !
Why can't we use physical refraction technology?
If electrons are incident obliquely from one transparent medium into another transparent medium, the propagation direction will generally change.
Refraction, like reflection of light, occurs at the interface between two media;
The light is simply reflected back into the original medium, while the refracted light enters another medium because the speed of light propagation in two different substances is different.
It is applicable to homogeneous isotropic media.
???
According to: the law of refraction;
The law that determines the relationship between the propagation direction of incident light and refracted light when light is refracted through the interface of two media. It is one of the basic laws of geometric optics.
The plane formed by the incident light ray and the interface normal passing through the incident point is called the incident plane. The angles between the incident light ray and the refracted light ray and the normal are called the angle of incidence and the angle of refraction, respectively, and are represented by θi and θt.
The law of refraction is:
①The refracted light is within the incident plane.
②The ratio of the sine of the incident angle to the sine of the refraction angle is a constant, represented by n21, that is,
sinθisinθt=n21
sinθisinθt=v1v2=n21
In the formula, n21 is called the relative refractive index of the second medium to the first medium.
The law that the ratio of the cosecant of the angle of incidence to the angle of refraction is a constant;
Right now
cscθicscθt=constant
Therefore, the law of refraction is also called Snell's law.
The law of refraction only applies to stationary interfaces consisting of isotropic media.
so! ! !
Therefore, the propagation direction changes at the junction of the two media, and 0.0MM seamless splicing can be achieved.
If we add a waterproof groove, there shouldn’t be any major problems!
Gotta try it!
Liu Chi directly opened the computer in front of him and looked for relevant information.
......
One week later.
Laboratory building assembly workshop.
"How is it?" Zhou Meng stretched his neck and looked at the big screen in Liu Chi's hand, which was made up of four 1000X1000MM screens, and asked.
"I can't see any problem for now." Liu Chi put the newly assembled screen away and said to Zhou Meng, "Turn it on and take a look?"
"Okay!" Zhou Meng turned the notebook on the table over and started to work: "Has it started?"
"Um!"
"Pah..." As soon as Liu Chi finished speaking, Zhou Meng lightly tapped the enter key with his middle finger.
Half a minute later.
?
? ?
Zhou Meng's face was full of question marks.
Why is the screen unresponsive?
Liu Chi also looked at the black screen curiously, walked around it twice, checked the line problem carefully, and finally shook his head at Zhou Meng.
Doesn't that make sense?
Not to mention the pattern, it doesn't even light up now.
"Turn it off first and take it apart to have a look." Liu Chi couldn't find the problem in the end, so he had to give up temporarily and take it apart to check again.
"Yeah!" Zhou Meng responded and turned off the generator.
Two hours later!
"Zhou Meng, do you think the material might get stuck and become unusable?" Liu Chi scratched his forehead.
"That shouldn't be the case. I'm using plasma phosphor luminescence imaging technology, which is a very mature technology. It doesn't make sense that it won't work, right?"
"I mean that coating on your back."
"Huh?" Zhou Meng was stunned for a moment, and finally said: "It should be okay, right?"
"Do you have any samples? Take them to the detector for testing."
"Yes, I'll get it." Zhou Meng put down the notebook in his hand and ran out of the workshop.
"......"
I would like to recommend a new book by my friend (Power Grid Master) Little Seedling!
