Dark crystals can be transformed from a solid state to a liquid state.
The LCD screen is not made of crystal.
LCD liquid crystal display is the abbreviation of Liquid Crystal Display, the structure of LCD is to place liquid crystals in two parallel glasses, and there are many vertical and horizontal thin wires between the two glasses, which control the rod-shaped crystal molecules to change direction by electrifying or not, and refract the light to produce a picture. Much better than CRT, but more expensive.
LCD LCD projector is the product of the combination of liquid crystal display technology and projection technology, which uses the electro-optical effect of liquid crystal to control the transmittance and reflectivity of the liquid crystal unit through the circuit, so as to produce beautiful images with different gray levels and up to 1670 million colors. The main imaging device of an LCD projector is a liquid crystal panel. The volume of an LCD projector depends on the size of the LCD panel, the smaller the LCD panel, the smaller the size of the projector.
According to the electro-optical effect, liquid crystal materials can be divided into two categories: reactive liquid crystal and inactive liquid crystal, among which active liquid crystal has high light transmittance and controllability. The liquid crystal panel uses active liquid crystal, and people can control the brightness and color of the liquid crystal panel through the relevant control system. Like liquid crystal displays, LCD projectors use twisted nematic liquid crystals.
The light source of the LCD projector is a special high-power bulb, and the luminous energy is much higher than that of the CRT projector that uses fluorescent light, so the brightness and color saturation of the LCD projector are higher than that of the CRT projector. The pixel of the LCD projector is the liquid crystal unit on the LCD board, and once the LCD board is selected, the resolution is basically determined, so the function of the LCD projector to adjust the resolution is worse than that of the CRT projector.
LCD projectors can be divided into single-chip and three-chip types according to the number of internal LCD panels, and most modern LCD projectors use three-chip LCD panels (Figure 1). Three-chip LCD projectors use red, green, and blue LCD panels as the control layer of red, green, and blue light. The white light emitted by the light source converges into the dichroic mirror group after passing through the lens group, and the red light is first separated and projected onto the red liquid crystal panel, and the image information represented by transparency under the "recording" of the liquid crystal plate is projected to generate the red light information in the image.
Green light is projected onto the green liquid crystal panel to form the green light information in the image, and the same blue light is generated in the image after the blue liquid crystal plate, and the three colors of light converge in the prism and are projected onto the projection screen by the projection lens to form a full-color image. Three-chip LCD projectors have higher image quality and higher brightness than single-chip LCD projectors. LCD projectors are smaller in size, lighter in weight, simpler in manufacturing process, higher in brightness and contrast, moderate in resolution, and now LCD projectors account for more than 70% of the overall market share, which is the projector with the highest market share and the most widely used projector in the market.

Hehe, I don't know, it's such a profound question.

The English name of crystal is rockcrystal, also known as spar and crystal stone.
Crystal is a colorless and transparent quartz crystalline mineral. Its main chemical is silica, which is a substance that "comes out of the same womb" as ordinary sand. When silica crystallizes perfectly, it is crystal; After silica gelatinization and dehydration, it is agate; The aqueous colloids of silica become opal when solidified; When the silica grains are less than a few microns, chalcedony, flint, and secondary quartzite are formed.

The solid state is actually silica.
-
Definition of crystal: Broadly speaking, atoms, ions, and molecules are regularly arranged and combined in three-dimensional space.
-
Of course, it is certain to become solid. However, it is not certain whether it can be turned into a crystal, because in the process of melting into a liquid, the crystal lattice is destroyed, and the long-range periodic arrangement in the crystal does not exist, and crystallization requires certain conditions, such as temperature gradient and nucleation power, which will affect the crystallization process.
Crystal refers to the substance with a three-dimensional periodic arrangement of atoms, ions, and molecules contained in the body, and is a long-range orderly arrangement, which is distinguished from amorphous solids (such as vitreous), liquids, and gases by this prominent structural feature.

Some. Liquid crystal is a kind of polymer material, because of its special physical, chemical and optical properties, it began to be widely used in thin and light display technology in the middle of the 20th century. The familiar state of matter (also known as phase) is gas, liquid, and solid, and the more unfamiliar ones are plasma and liquid crystal.
The liquid crystal phase is produced by a combination of molecules with a special shape, which can flow and have the optical properties of crystallization. The definition of liquid crystals has now been broadened to include substances that can be liquid crystals in a certain temperature range and are normally crystallized at lower temperatures. The constituent substance of liquid crystals is an organic compound, that is, a compound composed of carbon as the center.
Liquid crystals with two substances at the same time are combined with intermolecular forces, and their special optical properties are sensitive to electromagnetic fields, which are of great practical value.
So stop scribbling on the screen and be careful of leaking ......

Yes liquids are used to refract light.
The liquid is still strawberry-flavored.
-
Yes, but not like water, but oily and sticky!

MeltingMelting is a chemical term that refers to the wide range of melting of crystals from solid to liquid We can say, 'I melt in that sunshine'
But you can't say, 'I'm melting in that sun'
To put it bluntly, the melting literary meaning is stronger
Melting is a chemical term for the profession.
-
It should be melted and not melted!
-
No, after smashing, there is phosphor inside.
-
Let's make up for physics, and see what is "liquid state", not liquid state.

Dai Zhengjian. The first in China.
At the end of next year, I will use my own screen.

Dizzy! I 08 years in Suzhou Samsung LCD **** work, for the situation you said, I can tell me, whether it is LED or cold cathode fluorescent lamp backlight TFT-LCD LCD, these don't matter, but you are now talking about whether there is mercury in the LCD panel, whether it will volatilize this I really don't know, but the most important thing I want to tell you is that the LCD panel is composed of two pieces of glass, the manufacturer carves out the line with a machine on the glass, and then pours the liquid crystal, Put two pieces of glass together, if you are now the LCD panel is broken, then you have to be careful, because the liquid crystal is a substance extracted from petroleum, if the liquid crystal surface is not energized or heated, the liquid crystal is from the solid state, after electricity or heating, it will become liquid, if you have a wound bleeding on your body, contact with the liquid crystal, it is estimated that you will get leukemia. I hope you can see my message!!
This thing is worthless, 500w is not enough, because there are fewer 80 plays, and they are all wood, ** generally do not want wood phase 5, to be phase 5, just ignore all the abnormalities, our district 80 earth phase 5 house auction house 500w price no one wants.
Don't listen to their nonsense.
It's better to see for yourself. >>>More
