What is a non -human liquid crystal?
neematic Liquid Crystal Is and Translucent Liquid That Changes The Polarity of Light Waves Passing Through It. The Word "Nematic" Comes From the Greek Word for Thread, and Describes the Thread-like Formations That CAN Form in the Liquid Crystal. Nematic Liquid Crystal Is Frequently Used in Liquid-Crystal Displays (LCD) SCREENS SCHOP AS THOSE ON DIGITAL WATCHES.
Liquid Crystals are an intermediate melting stage between and Solid State And a Liquid State. In 1888, an Austrian scientist named Freidrich Reinitzer discovered a state when he conducted an experiments on a substance called cholesterol benzoate. The Substance, Reinitzer Noticed, Had Two Distinct Melting Points. In the first it became and cloudy liquid, and in the second it. Reinitzer's observations included concepts that the cloudy or crystalline state changed the polarity of the light waves passing through it, which is the concept necessary for the development of LCD.
Reinitzer Never Developed Practical Applicationty Liquid Crystal TechnologyE and the research of crystalline states were abandoned largely at the beginning of the 20th century. In 1969, a scientist named Hans Keller has successfully created a substance that would unstable at the room temperature. This discovery leads to the ability to commercialize the product, and nematical crystals have become very useful in the screen technology.
Three states of matter that most people learn in science class are liquid, gas and solid. The liquid crystal is the fourth condition, somewhere between liquids and solids, and allows you to go through some forms of matter. Like liquid substances, liquid crystal molecules have no position order, but as a solid may have molecules in liquid crystal, which means that they tend to point to one direction over time. Nematic liquid crystal is a high -temperature phase of the crystallization process where the molecules have long -term organizational order.
Light waves from natural orThey vibrate on artificial light sources in many ways. If most vibrations tend to be a specific direction, it is said that light is polarized. By operating light waves through an immo liquid crystal, polarization changes, usually by turning 90 degrees. If an electric field is added to the crystal solution, the direction and amount of polarization can be controlled by electricity voltage.
For creating a LCD screen, two polarized pieces of glass are used, one with a thin filter of non -non -non -water -liquid crystal. The glass is then connected to two electrodes that can provide electric charges. By starting the controlled rounds through the glass, the non -articular liquid crystal turns and spins, allowing only electrically desired light areas to go through. Screws using twisted non -human liquid crystals are common features in modern technology used in laptops and digital clocks and watches.
