What Is a Liquid Crystal?
Liquid crystal is a state of matter that exhibits properties between those of conventional liquids and solid crystals, characterized by its elongated molecular structure.
Temperature changes affect the organization of liquid crystal molecules, shifting them from ordered to disordered states. This unique behavior is the foundation of liquid crystal displays (LCDs), which include a liquid crystal panel, a backlight, and a color filter. By applying voltage, the orientation of the liquid crystal molecules is altered, controlling the light transmission. This mechanism allows the backlight to project light through the color filter, creating images on the screen.
Utilized in televisions, computers, smartphones, digital cameras, and watches, LCDs are prized for their slim profile, lightweight design, high resolution, and energy efficiency.
