Cathode Ray Tube. These displays are based on very old technology (the first CRT television was produced in 1934!). These displays are bulky, and are characterized by a slightly curved screen.
Some CRT units are available with a flat screen; these should not be confused with LCD’s. CRT monitors excel when they are used in monochrome applications; they display different shades of grey extremely well. This is very apparent when used in medical imaging equipment.
These displays are prone to burn-in after a long period of operation.
