What is the difference between a lcd and flat screen monitor?
These names are sometimes used interchangeably. But a true flat screen monitor is a CRT(cathode ray tube) based monitor that simply has a flat screen instead of a curved one. Whereas the LCD is typically thinner and doesn't use CRT technology but (LIQUID CRYSTAL DISPLAY) technology to display pixels on the screen.

Answer 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 whi…ch uses liquefied crystalline which reacts to electrical signals passed across it to display colors.
Answer A. The next answer has nothing to do with this question. I will return when I have a more complete answer, but to begin with an LCD TV has a tuner in it while an… LCD Monitor does not. LCD TVs are designed for use in higher light situations such as a bright room, LCD monitors are designed for use in controlled light environments such as offices. There are other differences, but you need to compare them directly which is hard since most Web sites don't allow cross category comparison. The best way to compare is to go to a big box retailer and compare them. But of course TVs and Monitors are in different departments. If you ask nicely maybe they'll let you set them up side by side. A. Outward appearances are definitely deceiving when it comes to LCD and Plasma televisions. Although both types of televisions are flat and thin, they employ different technology in an attempt to deliver similar results. Plasma TV Overview Plasma television technology is based loosely on the fluorescent light bulb. The display itself consists of cells. Within each cell two glass panels are separated by a narrow gap in which neon-xenon gas is injected and sealed in plasma form during the manufacturing process. The gas is electrically charged at specific intervals when the Plasma set is in use. The charged gas then strikes red, green, and blue phosphors, thus creating a television image. Each group of red, green, and blue phosphors is called a pixel (picture element). Although Plasma television technology eliminate the need for the bulky picture tube and electron beam scanning of traditional televisions, because it still employs the burning of phosphors to generate an image, Plasma televisions still suffer from some of the drawbacks of traditional televisions, such as heat generation and screen-burn of static images. LCD TV Overview LCD televisions, on the other hand, use a different technology (see also question #1 for this same explanation). Basically, LCD panels are made of two layers of transparent material, which are polarized, and are "glued" together. One of the layers is coated with a special polymer that holds the individual liquid crystals. Current is then passed through individual crystals, which allow the crystals to pass or block light to create images. LCD crystals do not produce their own light, so an external light source, such as florescent bulb is needed for the image created by the LCD to become visible to the viewer. Unlike standard CRT and Plasma televisions, since there are no phosphors that light up, less power is need for operation and the light source in an LCD television generates less heat than a Plasma or traditional television. Also, because of the nature of LCD technology, there is no radiation emitted from the screen itself. Plasma vs LCD The ADVANTAGES of Plasma over LCD are: 1. Larger screen size availability. 2. Better contrast ratio and ability to render deeper blacks. 3. Better color accuracy and saturation. 4. Better motion tracking (little or no motion lag in fast moving images). The DISADVANTAGES of Plasma vs LCD include: 1. Plasma TVs are more susceptible to burn-in of static images. 2. Plasma TVs generate more heat than LCDs, due to the need to light of phosphors to create the images. 3. Does not perform as well at higher altitudes. 4. Shorter display life span (about 30,000 hours or 8 hrs of viewing a day for 9 years) than LCD. However, screen life span is improving to as high as 60,000 hours. due to technology improvements. LCD television ADVANTAGES over Plasma include: 1. No burn-in of static images. 2. Cooler running temperature. 3. No high altitude use issues. 4. Increased image brightness over Plasma. 5. Longer display life (about 60,000 hours - at which time all you may need to do is replace the light source, not the entire set). This can vary according other environmental and use factors. 6. Lighter weight (when comparing same screen sizes) than Plasma counterparts. DISADVANTAGES of LCD vs Plasma televisions include: 1. Lower contrast ratio, not as good rendering deep blacks. 2. Not as good at tracking motion (fast moving objects may exhibit lag artifacts) - However, this is improving. 3. Not as common in large screen sizes above 42-inches as Plasma. However, the number is growing fast, with some LCD sets having a screen size as large as 65-inches now available to the general public. 4. Although LCD televisions do not suffer from burn-in susceptibility, it is possible that individual pixels on an LCD televisions can burn out, causing small, visible, black or white dots to appear on the screen. Individual pixels cannot be repaired, the whole screen would need to be replaced at that point, if the individual pixel burnout becomes annoying to you. 5. LCD televisions are typically more expensive than equivalent-sized Plasma televisions (although this is changing), especially when comparing EDTV Plasmas to HDTV-LCD Televisions.
Same thing except LCD TVs are televisions by themselves while LCD monitors can serve as either a television OR a computer monitor.
LED is a technology used in LCD monitors for improving the energy efficiency of the system 2nd answer: Also to make the colors and picture sharpness much better. An LCD screen… puts out no light. Zero. So in the older LCDs, fluorescent lighting behind the screen was utilized, but the color tended to be a titch on the green side. And the LCD screen that is lighted by LED lights behind it has no such color problem. Also, since the LEd lights can be made so tiny, the picture on an LED LCD is sharper.
lcds are smallerand CRTs are larger in shape crts areprone to flickerand LCDs are free from flicker.because they do not rely on a scaning electron beam
the difference is the name and the style
Obviously, the main difference between a plasma and LCD monitor is that plasma screens use plasma gas to generate an image and LCD's use liquid crystals. Plasma screens …have a much longer response rate which will leave "screen burn" or a persisting image after the image is gone. LCD's have a much quicker response time that is best for fast paced games. Both monitors use the same imput and are capable of high definition images. LCD's usually have higher contrast ratios which yields much sharper images although their maximum size is less than that of a plasma monitor.
the monitor is made of the box and the screen which the screen could a lcd or crt
A flat screen uses either Liquid Crytal Display technology (LCD) or Plasma, to create the array of coloured pixels. CRT stands for cathode ray tube. This fires electrons onto …a fluorescent screen with an aperture over it to produce a series of pixels. CRT's emit a small amount of X-Ray radiation, flat screens do not. LCD technology can also use more efficient back lights such as LED's so can be more power efficient.

LCD (liquid crystal display) is used for flat screensCRT are no energy efficient,LCD are energy …efficientLCD - compact , portable, light weighted, CRT- weighted, and large in size as compared to LCDLCD- uses liquid crystals to form the images, CRT- uses a cathode ray tube or electron gun to form the images
Older computer monitors are based on a cathode ray tube, hence the name CRT monitors. Most CRT computer monitors have a VGA input or a VGA compatible input. Many years ago, c…omputer monitors used display standards such as CGA, EGA and Hercules. All were digital interfaces with restricted color depth. CGA was limited to 16 colors, EGA had 64 and Hercules was a monochrome image limited to black, white and bright white. The connection to the monitor was a 9 pin D connector, the same size as a VGA 15 pin but with fewer pins. If any of these monitors survive, they will not take a VGA signal. Any monitor with a VGA 15 pin connector is very likely to accept VGA signals but be warned that they are normally limited to lower resolutions than modern LCD displays.
There are advantages and disadvantages to both the LCD flat screen television and the LED screen television. The best way to determine the differences and your preferences is …to visit a local electronic store to compare which television will work for you.
The CRT monitor. These are heavy, use a lot of desk space and electricity. It is the oldest technology used by monitors and is based on the cathode ray tube technology that wa…s developed for television. Monitors are made with better parts which give a much higher display resolution and picture sharpness than a television. This type of monitor is no longer popular. The LCD monitor. Often called a Flat panel display. It is a newer technology than CRT. LCD monitors use much less desk space, are lightweight and use less electricity than CRT. This type of screen has been used for many years in the screens of laptop and notebook computers. It is also used for screens in every mobile phone, and many handheld technologies. It can produce a very high quality and stable display of graphics and text.
A Plasma TV is created buy using a neon-xeon gas in glass that is sealed by plasma. To create an image, electric current is passed through the gas to make it light up. An LCD …TV has two layers of a clear material that has the liquid crystals locked between the layers. A light source is need for the LCD to work since the crystals do not hold light. The light actives the crystals and the crystals emit colour.
For an in-person purchase experience, one can purchase a flat screen LCD monitor at any electronics store or office supply store, such as Office Depot or Best Buy. Online, one… can find flat screen LCD monitors on Amazon, at Computer Hope, or at websites for electronics stores.
An LCD monitor utilizes liquid crystals between two glass panels. A plasma monitor uses gases rather than liquids. There are benefits and drawbacks to both technologies. An LC…D monitor is best when viewed in a direct line while an plasma can be viewed at an angle. However an LCD is a better choice in a sunny room as there will be less glare.
