Honghuang, I am engaged in science and technology in the Wuzu

Brilliant laboratory, display technology research area.

“This liquid crystal molecular color is not too high, but can carry out basic color display, due to technical problems, currently can only do 800 * 600 display, that is, 48K color display, if the processing technology is upgraded a step, we can achieve more than 100K color display.” The researcher pointed to the test data and said to Fang Hao.

“It’s already very good, after all, the color display is realized, which is much stronger than the previous black and white color.” Fang Hao said.

He was very satisfied with the progress of the display research, and with this display, he could make usable mobile phones, make usable computers, and build a network world in the flood waste.

The computer system consists of a motherboard with a chip installed, buttons, a monitor, and a network, and these technologies are slowly maturing except for the difficulties encountered by the display.

LCD display is composed of glass substrate, liquid crystal layer, liquid crystal circuit, backlight.

LED display by LED light as backlight, LCD display uses CCFL as backlight, this is the light source of the display, the earth with LED display more, because it is more energy-saving, smaller size, if CCFL as a backlight, power consumption is higher, but power consumption and volume are larger.

This luminescent material has been studied for decades, and it has not been completed recently, which is very bad luck, but high-precision miniature fluorescent lamps can be used instead of backlights, so that the volume of the display is large.

The substrate generally adopts a glass substrate, because the LCD screen is resistant to high temperature, suitable for batch manufacturing of large high-definition screens under vacuum and high temperature conditions, and the plastic substrate is generally used for flexible screens, because it can only be processed under normal temperature non-vacuum conditions, so it is generally used for small screens.

The liquid crystal circuit uses voltage to control the voltage at both ends of the liquid crystal lattice, and the voltage is different resulting in different electric field directions, which can deflect the liquid crystal molecules, so that the liquid crystal molecules are constantly converted in a transparent and turbid state.

The liquid crystal layer is a material composition called liquid crystal, which is between liquid and solid at room temperature, and some liquid crystals have different molecular arrangements at different voltages and different colors.

This liquid crystal substance is a polymer that is widely found in the sap of plants and is a fatty acid ester, but this liquid crystal is difficult to use on Earth.

In fact, the best liquid crystal is industrially synthesized, for liquid crystal polymer materials, Fang Hao has long arranged the project team for research, more than twenty years have passed, and there have been results.

In fact, its shape is a long rod-like polymer, if the long rod is arranged messily, it will be opaque, if it is arranged in order, it will be transparent, and the degree of chaotic arrangement will show different colors.

This polymer substance has the following requirements:

1. The shape is a long strip.

2. The molecular long strip is relatively strong and difficult to bend and decompose.

3. There is polarity at both ends, that is, molecular asymmetry at both ends can be affected by electromagnetic fields.

There are many types of molecules of this substance, and every time a molecule with better performance is found, the display technology is improved by a layer, which is the essence of screen display technology.

Although I know the principle, it is very difficult to manufacture a liquid crystal display, and there are many technologies involved.

For example, if it is a black and white color, it is easier to make pixels, and display black when the liquid crystal molecules become turbid, and white when transparent.

If you want to display color is more complicated, various colors can be composed of three primary colors, the three primary colors are red, yellow, blue.

In other words, each pixel should contain three liquid crystal squares, one square plus voltage to display red, one square plus voltage to display yellow, one square plus voltage to display blue, and power-down opaque to display black.

Not only that, to enhance the display effect, a pixel must contain multiple squares filled with liquid crystal molecules, and control the number of grids displayed, so that colors of different depths can be displayed.

For example, dark blue, you can show that all the blue squares are lit, light blue is displayed, you can display that the blue squares are only a few lit, and all the other cloudy opaque show black.

The more advanced the display, the more colors can be displayed, the higher the screen requirements, the more realistic the image displayed.

A color picture, not only contains the different pixels of the picture on and off, but also contains each pixel contained in the LCD grid on and off, so the color picture contains more information, to put it bluntly, the computer’s color picture is a data table, containing each position, each pixel in each LCD grid light and off situation.

In addition, processing technology is also a big challenge, the more pixels in the screen, the more realistic the image display, but as the pixels increase, the processing difficulty index level increases.

In fact, the manufacturing of screens and chips is somewhat similar, both use the lithography process for microscopic processing, and the precision required is very high.

At this moment, Fang Hao is looking at the experimental results in the display laboratory, which is testing the display of a liquid crystal molecule.

Soon, a color computer was assembled, turned on, displayed, and perfect.

“I announce that the first real computer in the flood famine has been officially born!” Fang Hao announced excitedly.

“Snap! Syllable! Syllable! Syllable! Syllable! There was a round of applause in the lab.

This computer integrates the most cutting-edge technology of the entire flood famine, involving thousands of mechanical equipment, millions of various experiments, hundreds of Chinese New Year’s Eve of research day and day, and there is a large warehouse of research data alone.

Counting the time is 388 years, this is still the case of Fang Hao cheating again and again, hundreds of years have basically squeezed out all his knowledge, and cultivated a large number of apprentices who surpassed him.

“Good! It’s not easy! He is full of tears, he is the biggest contributor, I don’t know how many materials have been studied, how many machines have been designed, how many experiments have been done, and how many brain cells have died.

The river is not the only one, the more than 500 people in this laboratory are the top scholars of the Flood Wilderness, and the most intelligent people among the 3.8 million living beings in the entire Flood Wilderness Empire have built high-rise buildings of science and technology from scratch, with the wisdom power to make the Flood Barren World tremble.
