difference between plasma and LCD????....plzzzzzz?

Question

technical differences plz n also wer plasma or LCD mostly used...in tv or computer???

Answer 1

Plasma: well i hav heard that for plasma tv u hav to get a "big rectangular device" to watch tv channels

LCD: however in LCD u don need that device to watch tv channels.

well, that's the only thing i noe bout it not sure though if it's correct
hope it helped ;) ....

Answer 2

If you're in the market for a big screen television -- and we are talking 42-inches and above -- then I'd suggest plasma as a safe bet. Plasmas give you more bang for your buck at the big end of town, and while LCDs can give you better resolution, the price difference is currently too wide. However, if money's not an issue and you want the sharpest image in town, then a large LCD is for you. At the smaller end of things (15" to 36" TVs), LCD is the only way to go if you want something slim and tasteful. And the best thing is that LCDs are getting cheaper all the time.

Thats funny because i just read this article before i came to this site. Here ya go.


Ask an expert: What's the difference between LCD and plasma TVs?

"Can you please explain the difference between LCD and plasma TVs?" - Robyn K.

TVs just keep getting bigger and better, while at the same time, becoming less expensive. Two of the more popular types of TVs are LCD and plasma flat-panel screens. Both have come a long ways since they were first introduced.

Is one better than the other?
LCD (Liquid Crystal Display) technology has been around for quite a while. The first time you saw them in use (in their monochrome versions) was likely to have been either in calculators or digital watches - many years ago. They're also the type of screen found in laptop computers and many computer monitors.

LCDs are known for their bright and vibrant images, resulting in an excellent picture even in well-lit rooms. Due to their higher resolutions, they are especially popular amongst videogame and computer enthusiasts.

Plasma displays, on the other hand, have quicker 'response times', which is important for fast action such as sports broadcasts. Response time is measured in milliseconds (ms) and a superior rating for an LCD would be 2-8ms, though higher ratings can be acceptable for general viewing.

Compared to LCDs, plasma displays provide richer colour, higher contrast, and deeper blacks. If your primary use is for watching movies, a plasma screen is sure to please.

Making great better.
Early on, both types of screens had their critics, with good reason, because each had significant weaknesses. LCDs typically had slow response times, which resulted in ghosting when watching fast action. Viewing angles were also criticized, with the screen looking washed out unless you watched from directly in front of the set. Like traditional tube TVs, plasma had the reputation of being susceptible to 'burn-in', when a static image is permanently etched into the screen.

While these characteristics still exist to some extent, both types of TVs have been improved to the point that these criticisms are largely a thing of the past. LCDs now feature much lower response times, so much so that even hardcore gamers have no objections in using them, and viewing angles have also been increased. Similarly plasma is not impervious to burn-in, but it's not a concern for those with regular viewing habits.

Although plasmas have traditionally been the better buy for large screens, LCDs are available in a wider variety of sizes at very competitive prices. Both types take up little space and are wall-mountable.

Lastly, the latest generation of LCD and plasmas have screen resolutions as high as 1080p, allowing you to maximize your enjoyment with HD sources like digital cable, digital satellite, HD DVD and Blu-ray Disc.

my family recently bought a new lcd so all this info is still fresh in my head plasma screens use a matrix of tiny gas plasma cells charged by precise electrical voltages to create a picture. LCD screens (liquid crystal display). Images are created by varying the amount electrical charge applied to the crystals. plasmas and lcds both display very good pictures but plasmas produce better blacks making it slightly better. But LCDs are catching up and the difference is only very small so what's better about plasmas? with plasmas your picture stays very good despite what angle you are viewing from whereas with LCDs the brightness and colour shifts a bit and plasmas come in bigger sizes, lcd usually tops at 52inchs but you can now get a 70inch sony and what's better about lcds? they can display more pixels, so more detail in the picture they use 30 percent less power (this is why we bought an LCD, we want to do as much as we can for the environment) and they're lighter, so if you want to mount your tv on the wall you're best with an LCD LCDs last longer, plasmas usually last between 30000 and 60000hrs of viewing whereas LCDs generally last more than 60000hrs and plasmas are far more likely to fall victim to having a ghost image, which is when an image is left on the screen too long resulting in the image to be permanently burned into the screen it is said that if you go 50+ inches you're better off with a plasma and if you're going smaller then an LCD but i still recommend an LCD because it produces so much less greenhouse gases oh and go samsung because samsung and sony have the same, best screens but samsung is cheaper because in order to make really good cheap screens you have to make heaps so samsung produce alot and then sony buy the screens off them making their product more expensive but not necessarily better edit: but yeh we got the samsung series 6, it's probably the best value tv on the market. In australia i think the 52 is currently going for about 4 grand

Answer 5

LCD works by controlling the light (from a bunch of fluorescent tubes usually) and letting some go through red green or blue dots on the screen. Turn the LCD clear behind the red, you see a red pixel, turn them all on you see white one. The switches are crossed polarisers and nematic crystals, so about half the light is lost in the switches.

Plasma works by making dots of coloured phosphors glow by belting them with electrons.

So one switched out light you don't want to see and one switches on light you do want to see. Because of that, 'black' LCD isn't quite black and 'white' LCD is still quite dim. Plasma black is really black and the bright is brighter than LCD.

Plasma also switches faster because it takes time for the LCD switch to recrystalise... so plasma blurs fast motion less than LCD.

Never seen a plasma in a laptop... they are power hungry. Never seen a plasma in a small TV... plasma can be made bigger than LCD.

Answer 6

Get an LCD, they are better for the home. Plasma's get burn in, are not easily viewed if someone is sitting more toward the side of the tv. LCD's are better if your house has windows, you won't see a reflection in the screen. Someone sitting toward the side of the TV can still see. Most computer screens are LCD.

Answer 7

Plasma displays uses a matrix of tiny gas plasma cells that are charged by precise electrical voltages to emit light and hence to create the picture image. In other words, each picture element in a plasma TV display acts as a miniature light source. More on plasma displays can be found in our article: How-it-Works: Plasma Display Panel.

Liquid Crystal Displays (LCD) panels - work by trapping a liquid crystal solution between two sheets of polarized glass. When an electric current passes through the liquid crystals, they change the polarization of the light passing through them in response to the applied voltage – as a result of which, more or less light passes through the polarized glass to reach the face of the display. LCD panels do not generate light - rather they filter or subtract light generated by a back-light source to create the image on the panel surface. More information on LCD displays can be found at How-it-Works: Liquid Crystal Display Technology.

Answer 8

They are used in both, the difference is LCD uses Liqiud Crystel Display a chemical reacts with Electrical pulses for changing color and showing picture on ur screen, as for Plasma it uses Plasma ions gas with the same Electrical pulses technology as LCD.
