The acronym LCD short for liquid crystal display, it is used in electronic visual or video and flat panel display systems. It uses the light modulating properties that are found in liquid crystals that do not directly emit the light itself. The LCD is able to display arbitrary or fixed images that include low-information content. It uses the same basic technology of what you see in segment displays such as those found in digital clocks. However, the LCD screen is much more complex as it consists of many small pixels.
Although only recently introduced on the market, the actual concept and manufacture of LCDs go back to the 19th century. You can find LCD technology in a wide range of applications that include the following;
- Computer Monitors
- Instrument & Cockpit Displays
- DVD Players
- Clocks & Watches
- Calculators, Telephones, and more
The LCD effectively replaced the old cathode ray tube (CRT) in virtually all applications. Plus, they are widely available in a large variety of screen sizes as compared to CRT and plasma displays. And, they do not suffer from image burn-in. However, they can suffer from image persistence which plagues many older LCD units.
Very energy efficient and safer than CRTs, the low electrical consumption means that many LCD displays can use battery power for small electronic devices. Essentially, it is a layer of liquid crystals on an electronically modulated device in front of a light or reflected light source. It can produce color or black and white images.
