What's the difference between a lcd and a crt monitor?

Question

opps i meant to ask the difference between LCDs and TFTs

Answer 1

liquid crystal vs tube projection

Answer 2

A monitor that uses liquid-crystal display technology called LCD monitor. Many laptop and notebook computers use LCD displays because of their low power requirements.

CRT monitor is a bowl-shaped screen made of a glass envelope containing an electron gun and a fluorescent screen that emits light when the gun releases electrons. The electron beam is then magnetically deflected, focused, and modulated in a way to form a image.The CRT monitor is the older, larger, and heavier version of the LCD monitors that we see today.

Answer 3

CRT Monitors

Sort for cathode-ray tubes, CRT monitors were the only choice consumers had for monitor technology for many years. Cathode ray tube (CRT) technology has been in use for more than 100 years, and is found in most televisions and computer monitors. A CRT works by moving an electron beam back and forth across the back of the screen. Each time the beam makes a pass across the screen, it lights up phosphor dots on the inside of the glass tube, thereby illuminating the active portions of the screen. By drawing many such lines from the top to the bottom of the screen, it creates an entire screen of images.

LCD/Flat panel Monitors

Short for liquid crystal display, LCD technology can be found in digital watches and computer monitors. LCD displays use two sheets of polarizing material with a liquid crystal solution between them. An electric current passed through the liquid causes the crystals to align so that light cannot pass through them. Each crystal, therefore, is like a shutter, either allowing light to pass through or blocking the light. Color LCD displays use two basic techniques for producing color: Passive matrix is the less expensive of the two technologies. The other technology, called thin film transistor (TFT) or active-matrix, produces color images that are as sharp as traditional CRT displays, but the technology is expensive.  

Answer 4

They work in completely different ways. CRT = Cathode Ray Tube, LCD = Liquid Crystal Display.

Answer 5

LCD are the flat ones which won't hurt your electric bills as much as CRTs, which are the bulky heavy ones only good for gaming.

Answer 6

CRT (cathode ray tube) uses a massive tube housed behind the screen to shoot light at the screen. It is much wider than an LCD (liquid crystal display) monitor which uses liquified crystaline which reacts to electrical signals passed across it to display colors.
