what is diff brtween FLAT ,LCD & PLASMA TV .?

Answer 1

Both LCD TVs and plasma TVs are thin as you could hope for (as in Flat). In screen size plasmas usually run larger though don’t usually come in smaller sizes, which is sometimes needed. Viewing Angle: Plasma have a wider viewing angle. Life Span: Both have good lifespan. Issues: Plasma sometimes suffer from “burn in” effect. LCD TVs are sometimes susceptible to a delay that causes the outline of figures or objects to appear jagged. Color: LCD TVs are renowned for a sharp picture and vibrant color. Plasma TVs are known for a wide range of colors and accurate color reproduction. Brightness: LCD TVs are said to do slightly better in bright-light conditions. Black Levels: Plasma TVs generally produce very black blacks whereas an LCD TV will produce a very dark charcoal gray. Contrast Levels: Plasma TVs, technically, are said to have greater contrast levels. Cost: Prices for both types of TVs are decreasing rapidly.

plasma is a gas, it burns to create the color....these TVs are flat panel tvs...LCD is a projection and also have flat screens but when looking at the back the base is wide. My 60" is flat LCD but the base is about 22". The main difference is plasma costs much much more and only lasts 5 to 6 years at best. An LCD projection, while somewhat larger at the base, looks like a plasma, but lasts 12-15 years and costs a fraction of the price. Hence, I bought a 60" that will last a really long time for 1800 dollars or could have had a plasma that was about 27" for about 2300 dollars. Hope that helped. Check out Circuitcity.com for more.

Flat tv refers to the old-fashion CRT (Cathode Ray Tube) that is flat instead of curved. (You can compare them at Target) The three primary colors, Red, Green, Blue, are three seperate electron guns. The idea behind an electron gun is to create electrons and then accelerate them to a very high speed. In a cathode ray tube (CRT) -- the big glass tube used in most televisions and computer monitors -- the electrons get aimed at the screen, where they light up the phosphor on the screen to create the image.

LCD technology is based on the properties of polarized light. Two thin, polarized panels sandwich a thin liquid-crystal gel that is divided into individual pixels. An X/Y grid of wires allows each pixel in the array to be activated individually. When an LCD pixel darkens, it polarizes at 90 degrees to the sandwiching polarizing screens. This cross-polarizing blocks light from passing through the LCD screen where that pixel has darkened. The pixel darkens in proportion to the voltage applied to it: For a bright detail, a low voltage is applied to the pixel; for a dark shadow area, a higher voltage is applied. LCDs aren’t completely opaque to light, however; some light will always penetrate even the blackest LCD pixels.

Plasma television technology is based loosely on the fluorescent lightbulb. 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).

Just to add to the LCD descriptions, most laptops have LCD flat screens, the screen on my iBook is only 1/8 inch wide, I know because I had to replace it. Gabi with the Plasma TV description was best. Personally I prefer LCD.

Most new flat screen tv's incorporate flat displays anyway. Sony Wega is so last year.

Answer 5

When you say "flat," it could refer to flat screen or flat display. Flat screen can refer to traditional TVs with flat tube (like Sony Wega). Flat display refers to LCD and Plasma.

In simple terms, traditional TVs use electrons that hit the back of the phosphor coated vacuum tubes to generate pictures. LCDs are made up of TFT (or thin film transistors), where each pixel is a transistor that enable controlling RGB (red, green, and blue) to form colors and images. Plasma is a gas-like substance that is heated to create pictures (think of fluorescent lamps and how they are lit).

Answer 6

flat could be crt or lcd

lcd is like the laptop displays.

what the flat means is the viewing area... its usually curved for CRT's until recently.
im not so sure with plasma so here:

A plasma display is an emissive flat panel display where light is created by phosphors excited by a plasma discharge between two flat panels of glass. The gas discharge contains no mercury (contrary to the backlights of an AMLCD); a mixture of noble gases (neon and xenon) is used instead. This gas mixture is inert and entirely non-harmful.

Answer 7

flat,lcd&&plasma tv are one and the same but the difference is the cost, size and the parts that is used to manufacture
