3. LCD - Pros
Good for still images – like computer monitors (not used for Videos or Gaming)
Takes up very little space – can be mounted on the wall
Bright color
Long life (30,000-50,000 hours)

4. LCD - Cons Artifacting Limited view
This happens when the screen cannot keep up with a fast moving object (like a football) causing the image to be “blocky” or delayed. This is extremely noticeable in screens over 35”
Limited view
The picture quality decreases as your angle of watching increases
The color black – unable to go fully black
Over 35” gets very expensive
Accused of having a “digital” look and do not produce colors “naturally”
Pictures can fade over time

5. DLP TV Digital Lighting Processing
Uses an optical semiconductor to manipulate light digitally
In DLP rear projection TVs white light mercury lamps are used as the TV’s light source

6. DLP - Pro
Initially costs less than Plasma and LCD TV.

7. DLP - Cons
High operation costs – needs a lot of maintenance and bulb replacement
Cannot be hung on a wall
As bulbs become dull, the picture quality fades

8. Plasma TV produces pictures by electrically charging tiny plasma gas bubbles coated in phosphor

9. Plasma Pros
BRIGHT! Up to 4-5 times brighter than an average TV and even after 50,000 hours it will still be 2-3 times brighter than an average TV
Most cost efficient and need little or no maintenance
No delay
Picture quality remains constant 180 degrees
Also takes up little space and can be mounted on a wall
Natural looking picture

10. PLASMA TV - Cons Affected by altitude
High altitudes cause the gases to work harder and cause the screen to wear out more quickly.
Older models have poor color contrast
Generate Heat
Due to the amount of heat produced, manufacturers install a fan, however the noise of the fan can become a pain.
BURN INS!
From video games and TV logos. If played/watched/left on for long periods of time a “ghost” image may appear
This can be avoided by not leaving the TV on a channel when you are not watching it or pausing something on the screen
Newer Plasma TVs address this problem by moving the image to surrounding pixels. (unnoticeable to the human eye)
Not available below 37”

Delay and Blocky, but BRIGHT!
Can be mounted on wall
DLP
Lowest
Needs bulb replacements, high maintenance costs
Picture can fade
Shortest
Dulls with Bulb
Takes up most space
PLASMA
Most bang for your buck
Burn-ins
Half as bright after 30,000 – 50,000 hours

12. General Concerns and Issues
Price is obviously a concern for most buyers. The problem with buying any type of flat panel TV is that prices tend to fall right after you guy them.
TVs do not last as long as you would like (pictures fade, burn ins etc)
Since it is a rapidly evolving area, your TV you bought today might be looking like an antique in 3 years.

13. EXCITING NEWS!! Laser TV?
A recent article in the New York Times boasts that Mitsubishi is planning to release a new type of TV late next year
Thinner
Will be ½ the weight of Plasma TVs that are about the same size. Contributing factors are smaller frames, and a screen of plastic-not glass.
Use less power
The life of TV will be significantly longer

14. Other New TV Technology
Toshiba and Canon have jointly developed “S.E.D.” or Surface-conduction Electron-emitter Display combines the technology of “old” TVs with digital flat panel technology.
This will also be introduced some time next year.
