Though, researches in the field of flat screen displays is presently on , it is uncertain as to which technology the lead goes to.

Plasma Display Panels (PDPs)

These use a thin layer of gas, like that inside a fluorescent lighting fixture, sandwiched between two-layers of glass to illuminate phosphor dots like those on CRT. Their big advantage that they can be easily made in the largest sizes. Prototypes up to 70 inch diagonal-far bigger than any picture tube that ever have been built. Unfortunately, it is not practical to build this type of screen in size much smaller than 20 inches and still maintain fine picture detail.

Liquid Crystal Displays (LCDs)

There are several versions of liquid crystal technology, using different materials and arrangements of the multiple layers used to make a display are thin and lightweight, of their multilayered construction and millions to make them much cheaper than they are now: usually 3 to 5 times the price of a CRT of the same size.

Field emission display (FED)

This is a flat variation of the standard CRT. It works almost the same way as the CRT. Beams of electrons in a vacuum strikes phosphors on a glass surface. The difference is in how the electrons get there. Unlike the CRT, each pixel, or point of light on the screen is provided with its own electron source, a tiny metal lump on a flat panel close behind the screen. There are no practical applications of this technology.

Reflective displays

This flat screen display technology uses tiny metallic mirrors on a surface, which changes shaper in response to electric charges. This technology is suited for projection systems.
