Hand rubbing nuclear fusion live in the wilderness

Chapter 205 AZO Transparent Film (seeking monthly pass)

Hearing that Han Yuan said to redesign a brand new display, the live broadcast room suddenly became lively.

【new technology? 】

[Newly designed thing? 】

[Why do you feel messed up looking at the drawings?Anchor, did you get it wrong?The previous drawings were all pretty standard. 】

[Let’s just say what it is, anyway, I can’t understand it. 】

[Sit in a row, eat fruit, the Little Sunflower Children's Class is starting!Next, we invite our keynote teacher to come on stage, everyone welcome! 】

[Come on, the melon seed peanut beer is ready, let's start the talk. 】

[Transparent electrode?What is it? 】

[What are AZO and polyaniline? 】

Netizens are not the only ones who are interested. Scientific scholars and experts from all over the world who were in the live broadcast room entered the live broadcast room as soon as they received the news.

Originally, these people were guarding all the time, but there were no new technologies and new things in the live broadcast of the won.

However, scientific research scholars and experts in various industries are very busy, and it is impossible to watch the live broadcast of KRW 24 hours a day.

In the absence of new things, everyone naturally has little interest in live broadcasts.

However, all countries and laboratories have arranged for special personnel to watch the live broadcast 24 hours a day. Once something new appears in it, these scientists or experts will be notified immediately.

Looking at the doubts on the bullet screen, Han Yuan said, "The display screen I made this time is an LCD screen."

"And AZO and polyaniline are two materials."

"AZO is an aluminum-doped zinc oxide material, which is synthesized by doping aluminum ions into zinc oxide."

"It is a direct-bandgap wide-bandgap n-type semiconductor material with a hexagonal wurtzite structure, which can be used to manufacture liquid crystal displays and thin-film transistors."

"It is the key material for the display I made this time."

"As for polyaniline, it is a polymer compound material with the same properties as AZO material. It is a conductive transparent liquid and can also be used to make liquid crystal displays."

【LCD? 】

[Semiconductors are really king, and the scope of application is really wide. 】

[It's a pity that my country's semiconductors are still catching up. It would be great if the anchor could release a technology live broadcast about semiconductors sometime. 】

[Everyone: LCD will never be a slave! ! ! !Black Shark: DC dimming chip.Everyone: Really fragrant. 】

[Now only oled can do screen fingerprints, so high-end mobile phones are basically oled. I feel that it is only a matter of time before oled completely replaces lcd. 】

[Speaking of which, can the anchor tell me why the screen can display the picture?I always find it amazing that electrical signals can be transformed into images. 】

【I worked as a color film technical engineer for a year after graduating from labor-management university, and my hair almost fell out. 】

[I'm also curious. The picture is superimposed one by one. How does the display control so many pixels? 】

Compared with the focus of attention of the audience in the live broadcast room, the focus of attention of scientists from various countries is completely different.

"AZO and polyaniline."

Two materials that can be used in transparent electrodes in liquid crystal displays!
Although polyaniline already exists in human society, the AZO aluminum-doped zinc oxide material is obviously a new semiconductor material.

Oxidized metal doping, can also be used as a semiconductor?

For scientists and experts in materials science from all over the world, this is a door that has never been opened before.

All the materials science experts who were watching the live broadcast involuntarily had faster heartbeats and heavy breathing, and their eyes staring at the live broadcast did not dare to blink for fear of missing any details.

Seeing the barrage on the virtual screen, Han Yuan concentrated his attention and replied: "This question is more complicated to explain."

"To understand how a display works, you must first know the three primary colors, pixels, and sub-pixels."

"The three primary colors are well understood, 'red, green and blue', which refer to the three basic colors that cannot be decomposed any further."

"The three primary colors can be mixed in a certain proportion to present various light colors. This is the basis for humans to see red, orange, yellow, green, blue, indigo, purple and other gorgeous colors."

"And a pixel refers to a smallest unit in an image represented by a sequence of numbers."

"In fact, the scenes and pictures we see in our daily life are all composed of tiny squares that the eyes can no longer distinguish."

"These smallest units or squares determine the final appearance of an image through the storage location and the assigned color value."

"As for sub-pixels, that is related to the knowledge points of liquid crystal technology."

"Everyone just learned that what we actually see is made up of pixels, and each pixel is filled with a different color to make it colorful."

"And the display screen we see needs to display different colors in different positions at different times, so it is not feasible to fix the color of each pixel."

"So how do you get the color onto the display?"

"It's all about subpixels."

"In fact, on an LCD screen, each pixel is composed of the three primary colors of red, blue and green."

"You can think of a pixel as a cube, and the middle is filled with three red, green, and blue light bulbs. These individual red, green, and blue light bulbs are called a "sub-pixel. "

"That is to say, actually on the LCD screen, the pixels are split again and arranged according to the Roman numeral 'III' or 'pin'."

"In this way, the color manipulation of pixels can be realized, and then the color manipulation display on the display can be realized."

"Understanding the three primary colors, pixels, and sub-pixels, we can understand the working principle of LCD screens."

"Each LCD screen needs a backlight, and the backlight is uniformly white."

"These white lights can appear colored after passing through the colored film."

"However, the content displayed on the display screen will change."

"That is to say, we need to adjust different colors on different pixels, and this is achieved through the liquid crystal layer."

"Liquid crystals, that is, liquid crystals, have unique optical properties, as well as a unique electromagnetic property."

"It can twist the direction of polarized light so that it can appear in a wide variety of colors."

"In short, the electrical signal controls the driver IC, and the driver IC will form an analog electrical signal to control the liquid crystal molecules."

"The liquid crystal molecules will control where the light is directed, and finally the light coming out of the liquid crystal molecules will appear on the screen after passing through the color plate."

After a pause, Han Yuan added another sentence:
"Of course, I have simplified these principles. In fact, the working principle of a screen is very complicated. If you really want to explain it, you can't finish it in three days and three nights."

After Han Yuan finished speaking, there was another complaint in the live broadcast room.

[Qiaoqiu, don’t be mean next time, don’t ask the anchor such questions again, I really really don’t want to hear these anymore. 】

[Dizzy, probably understand that the LCD is the key?Is that what you mean? 】

[Although I really want to say that this is the case, it is interesting, but after reading it, I blurted out it is still wc, I am sorry that I am too weak. 】

[Forgive me for not really understanding. 】

[The anchor explained very well, but I basically didn't understand|ω`). 】

[I am using the LCD screen to watch the live broadcast of the working principle of the LCD, and then comment on the LCD screen. 】

[So how is the screen so precise? 】
