Features of Plasmas
< 2 in thick (like LCD)

Brighter than LCD

(no polorization features)

Easily can be larger than LCds

Problem with burn-in

Can be supported by SED

Illuminates tiny colored florcented lights to form an image *each pixel made of red, green, blue lights*
=> varies in intensities of the different lights to produce different colors.
Polarization
Aborbs most of the light that strikes most of the light that strikes the filters and the remianing goes off to a right angle so you must look at center surface of screen
What is a Plasma?
a gas made up of free-flowing ions (electrically charged atoms)

The central element in a fluorescent light is a plasma, a gas made up of free-flowing ions (electrically charged atoms) and electrons (negatively charged particles).

In a plasma with an electrical current running through it, negatively charged particles are rushing toward the positively charged area of the plasma, and positively charged particles are rushing toward the negatively charged area.

In this mad rush, particles are constantly bumping into each other. These collisions excite the gas atoms in the plasma, causing them to release photons of energy.
Atoms used in Plasma
Xenon & Neon

they release LIGHT PHOTONS when excited

Mostly, these atoms release ultraviolet light photons, which are invisible to the human eye. But ultraviolet photons can be used to excite visible light photons
Main Advantage of Plasma
The main advantage of plasma display technology is that you can produce a very wide screen using extremely thin materials

DVR components:
1. The television signal comes into the DVR's built-in TUNER through antenna, cable or satellite.

=>If the signal comes from antenna or cable:
2. . it goes into an MPEG-2 encoder, which converts the data from analog to digital (MPEG-2, by the way, is the compression standard used to fit information onto a DVD).

2. From the encoder, the signal is shipped off to two different places:
I. first, to the hard drive for storage, an
II. d second, to an MPEG-2 decoder, which converts the signal back to analog and sends it to the television for viewing
DVR stands for:
Digital Video Recorder
DVR Operating systems

Shadow Mask How Stuff Works
A shadow mask is a thin metal screen filled with very small holes.


Three electron beams pass through the holes to focus on a single point on a CRT displays' phosphor surface.

The shadow mask helps to control the electron beams so that the beams strike the correct phosphor at just the right intensity to create the desired colors and image on the display.

The unwanted beams are blocked or "shadowed."
