1. True color LED: Glow diode (LightedElectronicDiode)
Explain: Use the one-way conductivity of diode, control its colour and gray scale with electronic circuitry, realize graph article, video presentation.
Advantage: 1. Brightness is tall, it is active glow equipment, do not suffer environmental effect, service life is long, individual attaint resembling element can be safeguarded and do not affect overall situation.
2. colour is gorgeous, the perspective is big. Without loss of joining together image, the big screen that can make the same score rice as number is used. . . .

2. colour is gorgeous, the perspective is big. Without loss of joining together image, the big screen that can make the same score rice as number is used.
3. is true pure number indication equipment.
Defect: Dot density is not at present high, do not suit close quarters to watch.
2. PDP: Plasma shows (PlasmaDisplay)
Explain: Besmear glow material is written after on whole glass quarter corrode is machined, control its colour and gray scale with electronic circuitry, implementation graph article shows.
Advantage: Laminose, managing space, use convenient.
Defect: Screen is small (42 inches are in the majority, exceed 52 inches hard) the price is high, cannot repair, cannot joining together is used.
3. CRT: CRT (CathodeRayTubes)
Explain: Use cathode ray (electron beam) the fluorescent material of the besmear on bombard Bo carapace gives off light to resemble.
Advantage: Color rendition sex is good
Defect: Size is small, resolution is low. The television is the greatest 34 inches, 38 inches. Blame plane shows, image has certain and lack fidelity. Joining together is used into TV wall have curved surface lack fidelity.
4. F-PRJ: umbriferous show (FrontProjection)
Explain: Person and projector distributing to be the same as side in screen, person eye relies on projector to watch image in the reflex on screen.
Advantage: Exceed big screen, image is almost OK and aleatoric size. The value is relatively inferior, the structure is simple, accomplish high resolution easily; Multimedia input.
Defect: Get ambient light the impact is big, contrast is low, sex of an organic whole is poor.
5. R-PRJ: The back is umbriferous show (RearProjection)
Explain: Person and projector distributing in screen two side. Person eye relies on the projectile light that projector comes out from the transmission on screen to watch image.
