Liquid Crystal Display commonly known as LCD is an
electronically modulated optical device made up of any number of pixels filled with crystal.. The one you called the screen.. facing you when you are in front of the lcd monitor
It needs light source for this to have display... the light source whose responsible for the image to be displayed is the backlight inverter.. Its in the form of a cold cathode lights...frequently located at the upper and lower back edge of the LCD screen..


Hope i clear things out for you...

Much appreciated if you rate this help..thanks..


LCDs therefore need a light source and are classified as "passive" displays
LCDs are more energy efficient, and offer safer disposal, than CRTs. Its low electrical power consumption enables it to be used in battery-powered electronic equipment. It is an electronically-modulated optical device made up of any number of pixels filled with liquid crystals and arrayed in front of a light source (backlight) or reflector to produce images in color or monochrome. The earliest discovery leading to the development of LCD technology, the discovery of liquid crystals, dates from 1888.[1] By 2008, worldwide sales of televisions with LCD screens had surpassed the sale of CRT units.
