The Death of the CRT

Is the CRT dead? The Cathrode Ray Tube has been around for more years than many of us, infact more than twice the years of some of us. It has been used for televisons, video monitors and computer display terminals.

But now, Apple computer has declared that the CRT is dead. In fact it has been all but dead for a couple of years, where the only system that had one from Apple was on the educational eMac.

Now Apple has stopped making the eMac as well and have announced a new $899 iMac for education.

CRT’s visual performance is comparable to LCDs, but suffer from much larger physical size and power draw. They also don’t make it easy to carry from one location to another. The educational market is one place where moving systems is common.

LCDs have another added value. They use less energy than CRTs. They also generate less heat than CRT, which takes less Air-Conditioning to cool the office.

As the price of LCD and plasma screens decrease, CRT’s may also become a thing of the past in the home Video market place as well.
