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
