What are the advantages and disadvantages of the cathode ray tube?

CRT is a mature technology, less expensive, higher contrast, and still produces brighter pictures than a flat-panel display of the same display area. These advantages are slowly being eroded with better flat-panel technology. The cons are more than offsetting its pros. Since CRT uses accelerated electrons and a phosphor screen, it has a little more harmful radiation (if not properly shielded), it uses more energy and generates more heat, and at the end of its life, produces more hazardous materials, not to mention that it occupies a larger footprint and weighs more than a flat-panel display.
