How does the LCD monitor work?


The liquid crystal display, which is a flat and ultra-thin display device, consists of a certain number of color or black and white pixels placed in front of a light source or a reflective surface.


The working principle of the LCD monitor:


Liquid crystal is a special substance between solid and liquid. It is an organic compound that is normally liquid, but its molecular arrangement is as regular as that of solid crystals. Therefore, it is named as liquid crystal. Its other special property is that if an electric field is applied to the liquid crystal, its molecular arrangement will be changed. At this time, if it is combined with a polarizer, it has the effect of blocking the passage of light. If it is combined with a color filter, the amount of transmitted light of a certain color can be changed, and the voltage at both ends of the liquid crystal can also be changed visually.
