Liquid crystal display power consumption is very low
- Apr 25, 2018 -

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. Liquid crystal displays consume very little power and are therefore favored by engineers for use in electronic devices that use batteries. Its main principle is that current stimulates liquid crystal molecules to generate points, lines, and planes with the back lamp to form a picture.

The working principle of liquid crystal display: Liquid crystal is a special substance between solid and liquid, it is an organic compound, it is liquid under normal state, but its molecular arrangement is as regular as the solid crystal, so the name liquid crystal Another special feature of this is that if an electric field is applied to the liquid crystal, its molecular arrangement will change, and if it is combined with a polarizer, it will have the effect of blocking the passage of light (in the absence of an electric field, the light can be Smoothly through) if the color filter is added, changing the amount of voltage added to the liquid crystal can change the amount of transmitted light of a certain color. It can also be said that changing the voltage across the liquid crystal can change its transmittance. (In practice, however, this must be matched with a polarizer.)
