whats the difference on a flat screen TV and an LCD is the flat screen still big at the back and and LCD slim?

Answer 1

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.

Answer 2

LCD is a liquid crystal display and the whole tv is usually quite slim. A flat screen could be an older CRT (cathode ray tube) screen, but it will have the big lump at the back of it.

Answer 3

If you search for “Flat Screen TV” in will come up with lots of references for flat screen LCD TVs and flat screen plasma TVs. So, Flat screen means just that. Older bulky TVs were available with flat screen CRTs.

Answer 4

LCD or PLASMA they are both slim but the plasma screen is soft to touch and the lcd is hard like glass
In my opinnion LCD is best .

Answer 5

u r right and one more difference is that the cathode ray tube is present in flat tv which ll emmit the rays and the picture tube ll recoginise it. where as in lcd tv the screen is having liquid cristals which doesnt want a cathode ray tube. by passing current it ll produice different colours. that makes it more finer in displayes

Answer 6

Yes.
