会计学1液晶显示器简介中英液晶显示器简介中英液晶的种类液晶的种类液晶的种类液晶的种类现有的液晶存在三种状态,目前现有的液晶存在三种状态,目前 LCD LCD 主要使用的是主要使用的是 Nematic Nematic 状态的液晶。状态的液晶。向列相液晶:向列相液晶:Nematic Nematic 分子种类的重心混乱无序,使其像普通液体一样可以流动,但分子杆的指向矢大体一分子种类的重心混乱无序,使其像普通液体一样可以流动,但分子杆的指向矢大体一致。致。进晶相液晶:进晶相液晶:Smectic LC Smectic LC 分子形成一层一层的结构,分子层的厚度大约是一个分子的长度;分子垂直于分子分子形成一层一层的结构,分子层的厚度大约是一个分子的长度;分子垂直于分子层平面排列,分子的重心在分子层中是无序的,形成一层层的二维流体。层平面排列,分子的重心在分子层中是无序的,形成一层层的二维流体。胆甾相液晶:胆甾相液晶:Cholesteric Cholesteric 分子的重心排列是无序的,但分子的指向矢在一个平面内大致指向一个方向。在垂分子的重心排列是无序的,但分子的指向矢在一个平面内大致指向一个方向。在垂直于这个平面上的方向上,分子的指向矢会旋转行程螺旋结构。直于这个平面上的方向上,分子的指向矢会旋转行程螺旋结构。The types of liquid crystalThe existing liquid crystal has three kinds of states,the LCD mainly uses the state of the Nematic liquid crystal.Nematic liquid crystal:The core of Nematics molecular type is chaotic,which makes it flow like ordinary liquid,but the pointing direction of molecular lever is broadly the same.Smectic LC:The Smectic LC molecules form layer and layer structure,and the thickness of molecular layer is about a molecular length;Molecular is plane tiling with perpendicular to the molecules.The core of molecular is disorder in the molecular layer,and form layer and layer of two-dimensional fluid.Cholesteric liquid crystal:The core arrangement of the Cholesteric molecules is disorder,but the pointing vector of the molecular is basically in the some direction.In the direction of perpendicular to this plane,the pointing vector of the molecular will rotate and form into helical structure.第1页/共6页液晶显示器的分类液晶显示器的分类液晶显示器的分类液晶显示器的分类按自发光和接收外部光源的分类按自发光和接收外部光源的分类Classification according to the self-luminous and receive outer lightClassification
