Images are produced when an electron beam strikes a phosphorescent surface of the specialized vacuum tube.

It is a type of flat-panel display that uses the light modulating properties of crystals combined with polarizers, a back-light or reflector is used to produce monochrome or color images on the screen.

Modern LCD monitors are back lit using LED (Light Emitting Diode) technology which gives better contrast and brightness.

LCD monitors used cold cathode fluorescent lamp (CCFL), that is essentially 2 fluorescent lamps behind the LCD screens which supplies the light source, prior to using LEDs.

LCD monitors used cold circle flask lamp (CCFL), that is essentially 2 fluorescent lamps behind the LCD screens which supplies the light source, prior to using LEDs.

OLED monitors used cold cathode fluorescent lamp (CCFL), that is essentially 2 fluorescent lamps behind the LCD screens which supplies the light source, prior to using LEDs.

CCFL stands for (a)
