A liquid crystal display, a flat ultra-thin display device consisting of a certain number of color or black and white pixels, is placed in front of a light source or reflection. LCDS are favored by engineers because they consume very little power and are suitable for electronic devices that use batteries. Its main principle is through the current to stimulate the liquid crystal molecules, and the back of the lamp to produce a point, line, surface, image formation. How liquid crystal display works: liquid crystal is a special substance between a solid and a liquid. It is an organic compound, usually liquid, but its molecules are arranged in a regular way like solid crystals, so it is called a liquid crystal. Another special property of liquid crystals is that if an electric field is applied to them, the arrangement of their molecules changes. If a polarizer is added to the liquid crystal, it acts as a barrier to the passage of light (which can pass without an electric field). The transmittance of a certain color can be changed by changing the voltage applied to the liquid crystal with a color filter. It can also be said that changing the voltage across the liquid crystal can change the light transmittance of the liquid crystal (but in practice, must be coupled with polarizing mirror).
