What is the difference between a LCD tv and a LCD monitor please?
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.

Answer: Unlike Plasma TV screens DLP and LCD last much are longer, and are considered to both have superior image quality. LCD screens tend to have slightly better contras…t, with a larger range of black and white color shades. DLP, however, still has faster refresh rates than LCD (although LCD has been vastly improved in this area over the last two years). This can have implications if you are really into high-action motion (sports, action movies), because movement may seem a little blurred with LCD at times. Also, you'll want to remember that in order for you to get the best color out of your LCD, you have to sit right in front of it. LCD TVs also have a slightly shorter lifespan than DLPs, with only 45,000 to 60,000 hours compared to 75,000 hours or more. As far as price goes, LCD and DLP are still more expensive than Plasma, but like all things in time, their price has been coming down. And right now, DLP is slightly more expensive than LCD, but not by much. DLP, in our eyes, is the best investment, at least for the next few years. The biggest difference is that DLP is a projection technology. Most TVs do not use projection screens.
An LCD is an elaborate, electrically controlled color filter. The light comes from either a florescent tube or a bank of LEDs. A plasma TV set generates light much like your o…ld CRT Television; a phosphor is activated and emits photons of a specific color. The advantage of an LCD is that they use much less power than a plasma and do not suffer from image burn in as plasmas may. The advantage to plasmas is that they have much better response times (for showing fast moving object), better performance at extreme viewing angles and are generally cheaper than LCDs in comparable sizes.
A LCD projector projects the image to a screen in front of it like a slide projector projects the images of slides onto a screen while a LCD tv projects from behind the screen… like a large TV, the image coming to the screen from behind it rather from in front of it. That is basically the only difference. You can usually get a much larger image from a LCD projector than from a LCD tv. Projectors usually require more planning and installation events and you can not just pick it up and move it to another room easily.
Plasma screens emit light, from small gas chambers arranged in the glass screen as a matrix. LCD use a system of shutters held in liquid crystal between sheets of glass, the l…ight comes from a light source behind, from florescent tubes or white LEDs. Plasma screens use a series of cells between glass panels which contain neon-xenon gas, when the gas is charged, the image is displayed. LCD uses polymer and a form of liquid crystal to display the image.
LCD (light crystal display) have better resolution and are more energy efficient. If you want a a more vibrant color and deeper black in your picture then the Plasma TV would… be best and are less expensive on your wallet.
A plasma TV is better than a LCD TV. haha! :-)
Same thing except LCD TVs are televisions by themselves while LCD monitors can serve as either a television OR a computer monitor.
Plasma panels give off image by using certain gases inside special cells and LCD panels give off image by modulating liquid crystals
Nothing. All led TV's are just lcd back lit by led's
Yes, but the LCD TV needs to have a VGA input.
thinner, better overall image quality and higher resolution, Normal television sets used a picture tube which at times delivered a snowy and distorted picture. a liquid cryst…al display provides sharper images and is far more energy efficient.
I believe you mean LCD and CRT's? Anyways, on a very basic explanation, CRT's are simply: CRT's - In the back there is a device used for shooting electro…ns at a phosphor-coated screen which produces the image you see. These beams are moved around on the screen by an internal or external device (electrostatic deflection plate). This process is repeated a number of times per second in order to keep up with the motion of the pictures shown. -For more in-depth into how that actually works with the electrons you need to understand one thing. The only reason you see what you do on the screen is because a charged electron striking a phosphor produces a certain amount of light depending on how much of a charge it has. These different charges are what give us brightness and contrast. Using different phosphors on the tube gives us our many different colors. It also has to do with the energy that is released by the electrons, but unless you are trying to learn Quantum theory, which I am going to assume not since you are asking the difference between the two tv types and not about Quantum theory itself, you don't really need to know all this... LCD's -They are in fact similar to CRT's in the sense that they are both only using charged electrons in order to produce an image, but LCD's have a different way of doing so. - In an LCD for example, aka Liquid Crystal Display, which has crystals in a fluid (which I can't seem to find the name of) and are electronically charged in order to create the different colors. The difference between LCD and CRT TVs is in what they have to offer. CRT TVs are heavy and bulky while LCDs are slim and conserve energy. Also, since LCDs contain no phosphors, they do not suffer from "image burn", which was sometimes a problem with CRTs. Liquid Crystals do not actually produce light, so they require a backlight behind the liquid crystal layer. Some backlights are flourescent, and some are Light Emitting Diodes (LEDs).
lcd having more life then led.
LED TVs are technically a type of LCD TVs, so the two terms are misleading. Basically, the main difference is the display. LED TVs use a backlighting to project the picture di…splay.
The biggest difference between an LCD and LED television is in the lighting. Both televisions have a liquid crystal display, however, with the LCD the lighting comes from fluo…rescent lamps behind the screen and with the LED the lighting comes from light emitting diodes behind the screen.
The main difference between an LED TV and an LCD TV is that the LED TV is back-lit by LED lights while the LCD TV is not. LED TV's are also more energy efficient than LCD ones….
The main difference between a computer monitor and an LCD TV monitor is the pixel density, which is nearly twice as high on a computer monitor. This is the main reason that a… computer monitor is more expensive. In addition, most computer monitors have a 16:10 aspect ratio, while TV monitors have a 16:9 aspect ratio.
