👉 A computer's fluid, often referred to as a liquid crystal display (LCD) or its predecessor, is a technology that forms the visual output of most modern computers. It works by manipulating light through liquid crystals, which are organic compounds that can change their alignment when an electric current is applied. This manipulation controls the amount of light that passes through or is blocked by thin layers of liquid crystals sandwiched between polarizing filters. By precisely controlling these crystals, the display can produce a wide range of colors and shades, creating images and text that we see on the screen. The underlying principle relies on the electro-optic effect, where an electric field alters the orientation of liquid crystal molecules, thus modulating light transmission and enabling the display's functionality.
