Users questions: I do have mobile phone LCD screen LCD sub was accidentally stained glass stab me (and the glass did not see the LCD has an LCD, the glass is transparent), do not know is not toxic? ? ?
Experts answer: full-called liquid crystal liquid crystal is between "solid" and "liquid" in the middle among states. 1 888 years, Australia has a bit of scientists called Lenny Branko a strange synthesis of organic compounds, it has two melting points. It's solid crystals when heated to 145 , it will melt into a liquid, but is turbid, and all pure substance melting Shique is transparent. If you continue when heated to 175 It once again melt into crystal clear liquid. Later, the German physicist Man put out in the "middle ground" of the turbid liquid, called liquid crystal. LCD Since its discovery, people do not know of any use, until 1968, it is only then as an important material for electronic industry. LCD Under normal circumstances, the orderly arrangement of its molecules, is clear and bright. However, after the electric field with the molecular arrangement is disrupted, some liquid crystal becomes opaque and darker in color, which can display numbers and images. According to the characteristics of the LCD will change, people use it to indicate the temperature, alarm, etc. ************* Containing N-alkyl carbazole and trans-stilbene structure units of Blu-ray emitter Solubility: soluble in toluene, chloroform, DMF (DMF is dimethyl formamide), insoluble in water and alcohol. Containing triphenylamine and trans-stilbene unit of blue light emitting material structure Solubility: Soluble in toluene, carbon tetrachloride, insoluble in water and alcohol. Structural units containing naphthalene units of green emission material Solubility: soluble in toluene, chloroform, carbon tetrachloride, insoluble in water and alcohol. ******************* 1) LCD touch open wounds, it should be flush with water Wounds, and immediately to the hospital. 2) the relevant operations involving liquid, sol gloves should be worn, and have the opportunity to avoid contact with exposed skin LCD. 3) there is evaporation of the liquid crystal operation, should wear the appropriate protective masks, and work in the shed with ventilated carried out.
