Types of Televisions:
Plasma
In Plasma technology, 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. 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.
Some Advantages of Plasma Televisions are:
Larger Screen Sizes Available
Better Contrast Ratio, so Blacks are deeper
Better Color Saturation
Little to no lag in Fast Moving Images
Some Disadvantages of Plasma Televisions are:
Susceptible to Burn-Ins(Image is “burnt” onto the screen when left on the screen too long)
Generates a lot of heat
Does not perform well at high altitudes
LCD
LCD stands for liquid crystal display. These types of displays 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.
Some Advantages of LCD Televisions are:
Low energy consumption
Reduced Glare
No "burn-in" effect
Cool running temperatures
No high altitude issues
Greater Brightness
Lighter in weight
Some Disadvantages of LCD Televisions are:
Low contrast ratio
Fast Moving Images sometimes lag
Individual Pixels can burn out and cannot be replaced
Smaller Viewing Angle (although not significant difference)
DLP
DLP (Digital Light Processing) technology utilizes a small Digital Micromirror Device (DMD) to tilt more than 1.3 million micromirrors-each of them less than the width of a human hair-toward (ON) or away from (OFF) the light source inside the DLP. This process creates light or dark pixels on the face of the projection screen. The light then filters to a color wheel, which rotates 120 times per second, producing the correct hue. Each mirror can turn on or off several thousands of times per second resulting in a technology that can reproduce up to 1024 shades of gray.
Some Advantages of DLP Televisions are:
Little to no affection by ambient light
Better Contrast Ratio, so Blacks are deeper
High refresh rate
No lagging images or burn-ins
Not affected by altitudes
Tuner built-in in most models
The only thing that can burn out is the bulb, which can be replaced, so you could use this TV virtually forever
Many connections available - Can also be used as a monitor
Some Disadvantages of DLP Televisions are:
Must be viewed at eye level for the best picture
While a bulb will only cost around $200, a professional will need to install it, incurring an additional cost.
They are heavy and cannot easily be moved.
Direct View(CRT)
Direct-view TVs, also known as the traditional tube television, consist of a single cathode ray tube (CRT) and electron beam that excites and illuminates phosphors on the inside surface of the TV screen.
Some Advantages of CRT Televisions are:
Low in cost
Best black level, contrast, shadow detail and color performance of any video technology out there
Not affected by ambient light
Can be viewed from any angle
Very Long Life Expectancy
Some Disadvantages of CRT Televisions are:
Size and Weight of Television make it very heavy
Limited screen size - 38 inches is about the max for CRT TVs
Uses old technology
Choosing the Best TV Size:
Where you are putting your television and what you are using it for will determine the perfect TV size for your room.
Living (or Family) Room
For living rooms and other spaces with high TV use, 37 inch and larger are the most popular choices. In large rooms, the largest size possible is usually best.
Bedrooms
For bedrooms, offices and other medium-sized spaces, a tv that is from 26 to 37 inches is your best bet.
Kitchens & Smaller Rooms
For kitchens and smaller rooms where you will be close to the TV, a 15 to 19 inch screen is best suited.

High Definition vs. Standard Definition
Standard definition is analog signals with resolution of 480i (480 lines drawn onscreen in an interlaced pattern, odd lines separately from even), the format in which TV content is delivered over regular analog broadcasts and basic (non-digital) cable. On the best TVs, the picture quality can be very good or even excellent, but it doesn't compare to the best that HD can offer.
Enhanced definition falls between standard and high definition. ED signals are digital, with resolution of 480p (480 lines scanned progressively). This is equivalent to DVD quality, which is a little better than standard definition but not as good as high definition. Some ED sets can accept HD signals, but they convert them to a lower resolution that they can display, so the picture quality won't match that of true HD. On the best EDTVs, it can be quite good.
High definition offers the best TV viewing possible. HD is a digital-TV format that contains more and finer detail than other formats, so images can have almost lifelike clarity. The picture quality can be stunning, especially on a large, wide-screen set. In technical terms, HD images have higher definition, meaning more picture elements (lines or pixels) make up each image. Most HD broadcasts today are either 1080i (1,080 lines drawn on-screen separately in an odd/even pattern, then interlaced to form one image) or 720p (720 lines scanned in one sweep, or progressively). Another HD format, 1080p, has 1,080 lines drawn in a progressive pattern, which potentially yields the finest detail. This format isn't yet being used for TV broadcasts, but some HD DVDs that support 1080p are expected to arrive this year. TVs with 1080p native resolution have already started to appear on the market.

HDMI (High-Definition Multimedia Interface) is an uncompressed, all-digital signal that combines both audio and video. This connection gives you the optimal 1080p signal and up to 7.1 channel sound. |
| DVI |
Highest |
Digital |
DVI (Digital Video Interface) is a video connection that will deliver 1080p video signal, but it does not carry audio signals. |
| Component Video |
Good |
Analog |
Component Video, or RGB, is an analog signal connection that splits the video into 3 separate signals, 2 for color and 1 for brightness. The maximum resolution on this connection type is 720p or 1080i. |
| S-Video |
Decent |
Analog |
S-Video (S for Separate) is a type of component video signal because the color and brightness signals are transmitted on separate wires. S-Video is not used for high definition resolutions. |
| Composite Video |
Average |
Analog |
Composite, or RCA, connections can be found on almost all video components. Color and brightness pass over the same cable. Although it is the most common connection found, it is also the least quality. |
