What Does Liquid Crystal Display Mean?

A liquid crystal display (LCD) is a thin visual electronic device. It uses the modulating principles of liquid crystals. LCDs do not emit lights and therefore additional lights are used to make these visible. LCDs show fixed images with monochrome large elements (score board, clock), or arbitrary images with very small multicolor pixels (monitors of laptops, TV, PDA, camera, mobile phone).

Safeopedia Explains Liquid Crystal Display

LCDs are used for a wide range of purposes. These are used in machines and equipment as monitors including computers, laptops, instrument panels, and dashboards. They are used in communication and entertaining devices including televisions, projectors, PDAs, mobile phones, video gaming consoles, billboards, and signage. They are used also in instruments including clocks and watches, and calculators. LCDs became very popular as they are thin, light weight, inexpensive, and energy efficient. Thus, they quickly replaced CRT monitors and analogue displays.

Aside from the common uses, LCDs are used in most medical instruments. LCD information and warning panels, warning signs and notices help improve safety and promote better risk management. LCDs are more effective in workplaces than older analogue type indicators and instruments.
