👉 LCD (Liquid Crystal Display) computing refers to the technology that enables electronic devices to display visual information using liquid crystal molecules and an electric field. At its core, an LCD screen consists of a backlight (usually LEDs or CCFLs), liquid crystal layers sandwiched between two glass substrates, and a polarizing filter. When an electric current is applied to the liquid crystals, they rotate, altering their alignment and allowing light to pass through or be blocked, thus creating pixels that form images. This process is controlled by a microprocessor or other control circuitry, which sends signals to the LCD to display data, graphics, or text. The efficiency of LCDs in converting electrical signals into visible images has made them ubiquitous in modern computing devices, including laptops, smartphones, and monitors, due to their low power consumption, thin profile, and high resolution capabilities.
