Chapter 179 Screen Clearance
The road is muddy, but the future is definitely bright!
Wang Haotian believes in this...it is unquestionable!
We now have a great demand for LCD glass substrates. We need to use two LCD glass substrates on one screen. Think about it, you can know how much mobile phones there are in the world. Moreover, LCD glass substrates are not only used on mobile phones, but also on other display screens.
For example, TVs, computers, etc., as long as there is a display screen, LCD glass substrates are used!
There are three mature methods for producing liquid crystal glass substrates, including floating method, hole down-leading method, and overflow and melting method.
There are usually two glass substrates on each screen, one is used as the base glass substrate and the other is used as a color filter.
Because of different functions, the methods of manufacturing two substrates are also different. It should be emphasized here that these three methods can produce liquid crystal glass substrates, but the focus is different, and the effects are also different.
In order to achieve the best manufacturing effect, when manufacturing the underlying glass substrate, Wang Haotian chose the floating method, and when manufacturing the color filter, Wang Haotian chose the overflow and melting method.
"Supplement the raw materials!" Wang Haotian issued an order.
Raw materials... The most basic basic raw materials of glass are silica sand that we can see normally. Small silica sand can play a great role.
Trucks of silicon sand were transported to the workshop.
Of course, silica sand is only the one that accounts for the largest proportion, including limestone, boric acid, soda ash, feldspar and other things.
"Mixed together!" Wang Haotian said.
The staff were proceeding in an orderly manner according to his orders. Some of these staff were real humans, while others were high-simulation robots.
Some dangerous and important tasks that are not humane are completely left to high-simulation robots for doing.
Even workers have signed very strict confidentiality agreements. What you see in the factory cannot be leaked to outsiders at will, otherwise they will be subject to severe sanctions.
At the least, you will not be able to protect your work, and at the worst, you will be sent to jail.
No one dares to joke about this.
The work of mixing together is entirely done by high-simulation robots. Don’t underestimate the mixed materials. They are not as simple as they appear on the surface, but are placed in a certain order. There are strict standards for how much each raw material is placed and when to put it in.
All of these are written into the program of high-simulation robots. These high-simulation robots execute commands strictly according to the program, and will never be a slight difference.
It is worth telling that even humans don’t know that the ones working with them are actually some high-simulation robots.
Who can imagine that the guy who teases little girls and tells them dirty jokes is actually a high-simulation robot!
The entire process of producing liquid crystal glass substrates actually has three main steps: feeding, thin plate forming, and back-end processing.
What we are doing now is the feeding process. According to the best secret recipe provided by Wang Xiaofang, the materials are heat-processed in a certain order, and a low viscosity and very uniform glass melt is formed under a high temperature environment.
The current glass melt is in a liquid state. Then the glass melt is introduced into the liquid tin bed. There should not be too much glass melt entering the liquid tin bed. The amount of entry needs to be controlled because the viscosity of the glass melt is low. It can be operated with a baffle to control the thickness of the glass.
As the number of glass melts entering the liquid tin bed increases, the glass melts that have entered the liquid tin bed will solidify into solid after cooling. At this time, the glass plate that has been depotted by a guide wheel is taken out, and then annealed and cut into a liquid crystal glass substrate.
This is the floating method used. Because the glass melt floats on the liquid tin bed, it is used as a floating method.
When using the floating method to produce the underlying glass substrate, another assembly line is not idle, it is producing color filters.
As for the production of color filters, the overflow and melting method is used.
The glass melt is transported to the center of the melt pump through a rectangular molten pump, and then an overflow occurs. The overflowing glass melt will run to the bottom of the melt pump and combine to form an ultra-thin color filter.
"Inspecting the liquid crystal glass substrate." Wang Haotian said.
"Yes, boss."
Substrates were sent to the laboratory for analysis and testing.
The result was soon out.
"The thickness of the LCD glass substrate is 0.3mm, exceeding the thickness of the mainstream screen in the world!"
The main thickness of commercial glass substrates is between 0.5mm and 0.7mm, and now it is conquering a thickness of 0.4mm. The glass substrates manufactured by the Smart Hall have directly exceeded 0.4mm and reached an astonishing thickness of 0.3mm!
There has been a huge success in this regard!
"In addition, tension point, specific gravity, thermal expansion coefficient, melting point, softening point, chemical resistance, mechanical strength, optical properties, and electrical characteristics all meet the predetermined requirements and are at the world's leading level!"
The light and thinner you are pursuing now. The thinner the substrate, the thinner the screen you make will be and the more popular it will be.
The machine is running non-stop, and the LCD glass substrate is being manufactured at all times.
At this point... the entire process of producing screens, from equipment evaporation machines to material super-inwa alloys, fluorinated polyimides to liquid crystal glass substrates, can be said to have been conquered by Wang Haotian.
This is another pass after Wang Haotian passed the chip, this time it was the pass screen!
The meaning of screen clearance is no less than that of clearance chip.
Soon, the Palace of Wisdom posted the situation where it could make LCD glass substrates on its official website. Now many people are always paying attention to the Palace of Wisdom, because even if there is a little bit of movement in the Palace of Wisdom, it may touch the hearts of people in the world.
Now the headlines on the Internet have been occupied by the scandals of a certain star, but as soon as the Palace of Wisdom announced that the LCD glass substrate could be mass-produced, it immediately occupied the headlines, and the click rate is rising at an incredible speed.
It soon exceeded tens of millions, not only in our country, but also foreigners are very concerned about the situation of the Palace of Wisdom.
"What? LCD glass substrates have been researched. Then it can be said that all the difficulties in making screens have been broken by the Palace of Wisdom. In other words, China can achieve localized production in everything that produces screens!"
"This is a heavy blow to the Japanese pirate country and the beautiful country."
