What is an LCD Display?
LCD displays are flat panel displays that use liquid crystals compressed between glass plates. The liquid crystals are neither a solid nor liquid, but a substance between the two, which can be twisted and untwisted with the application of electricity. When the twisted crystals are 'relaxed', the molecule will allow the full light from the fluorescent backlight to pass through polarized plates, creating the picture on the screen whereas a twisted crystal molecule is almost completely opaque, producing near to black. LED displays use the same Liquid Crystal Display technology, but use LED backlighting rather than a fluorescent lamp.
Why?
- LCD's produce a much sharper image than old fashioned CRT screens as they have many more pixels per inch.
- 100Hz refresh rate handles fast motion extremely well and free of blur.
- LCD's use up to 50% less power consumption than the equivalent sized Plasma! LED displays may consumed 40% less than LCD's!
- High lifespans, robust and no issues such as image burn-in.
- Space saving - LCD's can be mounted onto walls and are relatively thin compared to CRT screens.
