found the dish (discotic) liquid crystal , is a nematic or column line system high symmetry intact molecule composed of overlapping . In addition to pattern classification , the LCD because the condition ( condition ) generated is divided into different thermotropic liquid crystal (thermotropic LC) and lyotropic liquid crystal (lypotropic LC), respectively, by heating , adding a solvent to form a liquid crystal phase liquid crystalline phase heat generated two kinds of situations .
Lyotropic liquid crystal to generate example is soapy water . At high concentrations , the soap molecules lcd module are smectic interlayer water molecules . Lower concentrations , the combination is different.
In fact, a substance may have a variety of liquid crystal phase. It was also found that the two kinds of liquid crystal mixture is heated , then cooled to give an isotropic liquid , can be observed sequence of a nematic , smectic liquid crystal . This phase china lcd module change material , known and reproducible crystal (recentrant LC). The molecular structure .
Vanderbilt magic liquid crystal phase is stable between molecules . Because of the high density molecular assembly , repulsion anisotropy greater impact, but the attraction is to maintain a high density , so that the liquid crystalline state to achieve collective strength, repulsion and attraction of mutual checks and balances is very important. Another example is when molecules have polar groups, dipole-dipole interaction has become an important attraction.
Access to information mainly through display and interactive interface with the electronic technology and electronics integrated rapid development of LCD modules in the smart instrumentation to achieve a mix of graphics and text display, man-machine dialogue to achieve the on-screen menu operation thus graphic LCD module with its small size, low power consumption, the development cycle is short, safe, reliable, flexible, etc., in the smart meter has been more widely used.
