COG LCD Display The Temperature Rises

The substance has three states: solid, liquid and gaseous. These three states can also be called solid phase, liquid phase, gas phase. Most of the material in nature exhibits solid, liquid, COG LCD Display and gaseous as the temperature changes. Like water, salt, and substances from each element of the periodic table. Its constituent elements, such as water molecules or silicon atoms, are basically like a single ball. As the temperature decreases or the temperature increases, the arrangement of the constituent elements changes from a later disordered arrangement to a neatly ordered arrangement. From the liquid phase to the gas phase or solid phase. COG LCD Display In the crystal, the orderly arrangement of the constituent elements, indicating that each constituent unit is in a certain position, is not easy to flow and regular arrangement, as long as people know its arrangement rules, you can start from a constituent unit, COG LCD Display according to the law to find Another unit, that is, strict space orderly.

In addition to the solid, liquid and solid states we know, some substances, which change from solid to liquid, do not change directly from solid to liquid, but to an intermediate state. COG LCD Display In the middle of the material looks like the appearance of turbid liquid. But its optical properties and a certain electrical properties and crystal similar. Is the opposite sex, such as birefringence characteristics. Such as the temperature rise, a variety of turbid substances with the temperature rise will become clear, COG LCD Display homosexual liquid. In turn, these substances from the liquid into a solid, but also through the middle state. A variety of substances can be in a certain temperature range and the crystal, the two characteristics of the material called liquid crystal (LiquidCrystal) is also called liquid crystal phase, intermediate phase or intermediary equal, COG LCD Display also known as the fourth state of the material.

With the development of science, people know the improvement, found that liquid crystal substances are basically organic compounds. One of every 200 of the existing organic compounds is a liquid crystal phase. From the composition and the emergence of liquid crystal phase physical conditions, COG LCD Display the liquid crystal can be divided into thermotropic liquid crystal and lyotropic liquid crystal two categories. In some organic matter heating dissolved, due to heating damage to the crystalline lattice and the formation of liquid crystal called thermotropic liquid crystal, is the first few said because of heating some substances appear liquid crystal phase. Similarly, some organic substances in a certain solvent, due to the destruction of crystalline crystal lattice and the formation of liquid crystal called solute liquid crystal. It is a liquid crystal phase present due to a change in solution concentration. The most common are soapy water and so on. COG LCD Display Currently used for display materials are basically thermotropic LCD. So far, COG LCD Display has been found in the liquid crystal has more than 20,000 kinds.

The use of liquid crystal of the electro-optical effect of the liquid crystal on the electric field, COG LCD Display magnetic field, light and temperature boundaries under the conditions of change under certain conditions into a visual signal made of the display, that is, liquid crystal display.
