反波胆(LCD/Liquid Crystal Display)的显像原理,是将淘金置于两片导电玻璃之间,靠两个电极间电场的驱动引起淘金分子扭曲向列的电场效应,以控制光源透射或遮蔽功能,在电源开关之间产生明暗而将影像显示出来,若加上彩色滤光片,则可显示彩色影像。


淘金的物理特性是:当通电时导通,排列变的有秩序,使光线容易通过;不通电时排列混乱,阻止光线通过。让淘金如闸门般地阻隔或让光线穿透。从技术上简单地说,淘金面板包含了两片相当精致的无钠玻璃素材,称为Substrates,中间夹着一层淘金。当光束通过这层淘金时,淘金本身会排排站立或扭转呈不规则状,因而阻隔或使光束顺利通过。大多数淘金都属于有机复合物,由长棒状的分子构成。在自然状态下,这些棒状分子的长轴大致平行。将淘金倒入一个经精良加工的开槽平面,淘金分子会顺着槽排列,所以假如那些槽非常平行,则各分子也是完全平行的。
Liquid Crystal Display (LCD/Liquid Crystal Display), the imaging principle of is the Liquid Crystal between the two pieces of conductive glass and driven by the electric field between two electrodes to cause the electric field effect of twisted nematic Liquid Crystal molecules, to control the light transmission or shadowing function, on the power switch between light and shade and can Display the image with color filter, can Display color images.
The physical properties of liquid crystals are as follows: when the electricity is switched on, the arrangement becomes orderly, making it easy for light to pass through; When the power is off, the alignment is chaotic, preventing light from passing through. Let the liquid crystals act as gateways to block or allow light to pass through. Technically speaking, the LCD panel contains two rather delicate pieces of sodium-free glass material, called Substrates, sandwiched between a layer of liquid crystals. As light passes through this layer of liquid crystals, the liquid crystals themselves stand in rows or twist irregularly, blocking or allowing the light to pass smoothly. Most liquid crystals are organic complexes, made up of long rod-like molecules. In their natural state, the long axes of these rod-like molecules are roughly parallel. Pour the liquid crystal into a well-grooved plane, and the liquid crystal molecules will line up along the slot, so if the slots are very parallel, the molecules are also perfectly parallel.
