Which process is used to backlight an LCD monitor? Correct Answer White or RGB

Backlighting in LCDs:

  • A backlight is a form of illumination used in liquid crystal displays (LCDs).
  • As LCDs do not produce light by themselves, they need illumination (ambient light or a special light source) to produce a visible image. 

 

There are several methods of backlighting an LCD panel:

  1. By use of white or RGB (Red, Green, Blue) LED arrays.
  2. Hot cathode fluorescent lamp (HCFL)
  3. Organic light-emitting diode (OLED)
  4. Electroluminescent (EL) devices
