The basic components of laptops are similar in
The liquid crystal display (LCD) is also a component of modern laptops. An LCD Display Screen is a flat panel display, electronic visual display, or video display that uses the light modulating properties of liquid crystals (LCs). As LCD panels produce no light of their own, they require an external lighting mechanism to be easily visible. On most displays, this consists of a cold cathode fluorescent lamp that is situated behind the LCD display screen panel. For battery-operated units (e.g. laptops) this requires an inverter to convert DC to AC. Recently, two types of LED backlit displays have appeared in some televisions as an alternative to conventional backlit LCDs. In one scheme, the LEDs are used to backlight the entire LCD panel. In another scheme, a set of red, green and blue LEDs is used to illuminate a small cluster of pixels, which can improve contrast and black level in some situations.
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 segments filled with liquid crystals and arrayed in front of a light source (backlight) or reflector to produce images in color or monochrome. The most flexible ones use an array of small pixels.
Among the many companies that produce and sell laptops, laptop batteries, and laptop LCD screens, Dell, IBM, Gateway, and Compaq are the most well-know.
