Nestekidenäytölle refers to a liquid crystal display, commonly abbreviated as LCD. These displays are a type of flat-panel display technology that uses the light-modulating properties of liquid crystals. Liquid crystals do not emit light directly but rather use a backlight or reflector to produce images. They are a ubiquitous technology found in a vast array of electronic devices.

The fundamental principle behind an LCD involves passing light through a series of polarizing filters and liquid crystals. When an electric voltage is applied to the liquid crystals, their molecular orientation changes, altering the polarization of light passing through them. By controlling which pixels are activated and to what extent, different shades and colors can be displayed.

Early LCDs were monochrome and primarily used in calculators and digital watches. Over time, advancements in technology led to the development of color LCDs, significantly expanding their applications. Today, they are the dominant display technology for televisions, computer monitors, smartphones, tablets, and many other electronic gadgets. Their advantages include relatively low power consumption, thin form factor, and good image quality for many viewing conditions.
