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。
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.
