A reflective display that requires very low power for operation.

A technology popular in watches and calculators for displaying information, which also may be used for computer display screens—especially in portable computers.

A type of display that requires very little depth and thus can be found in compact projectors and flat-panel displays.

LCDs are useful because they're flat, small compared with CRTs, light in weight, and use very little power. They make ideal displays for portable computers. The early displays suffered from poor resolution and contrast, with a very limited viewing angle. Later displays have improved resolution (e.g. 640x480) with good readability. Back lighting does away with the need for reasonable ambient light, although this increases the power consumption considerably. Grey scale and colour LCDs are being produced using thin film transistor (TFT) technology, and large colour LCD monitors should eventually appear. [CRT, EL FLCD] Return

A liquid crystal display is a thin, lightweight display device with no moving parts. It is the technology that is used in calculators, mobile phone and PDA's and is increasingly replacing the Cathode Ray Tube (CRT) in monitors and TV's as well.
