What is an LCD? LCD stands for liquid crystal display. It uses liquid crystals because of their light modulating properties. They do not directly emit light Because it does not generate light itself, it relies on external light sources to operate. LCD displays are either an electronic viisual display, a video display, or a flat panel display.They can be used for a large range of products, including televisions, watches, calculators, video games, telephones, and computer monitors. Products like watches are not usually given a backlight, while things like video games are.
In 1888, Friedrich Reinitzer discovered the concept of the liquid crystal after he extrated cholesterol from carrots. In 1936, the Marconi Wireless Telegraph company were the first to use the technology practically, and patent it as well. In the 1990s is when LCD screens really began to take off in use with multiple types of technological surfaces. In 2007, sales of LCD televisions finally surpassed CRTS for the first time.
LCD displays can display arbitrary or fixed displays. Arbitrary displays would be something like a computer display, while fixed images that can be hidden or displayed would include digital clocks. The difference between all these is just the number of pixals involved. LCD screens are energy efficient and are ideal for use in battery powered equipment.
