You would like a flat screen tv meaning you really only have two possible choices..i.e either you buy a plasma or an LCD type. Since you want a small one I suggest u go for the LCD. The main differences between the two have been outlined below.
Color: LCD TVs are known for their sharp pictures and lively color. An LCD TV’s colors are vibrant and can wow you when you walk into a room. Plasma TVs are known for their wide range of colors and their accurate color reproduction. A plasma TV’s colors are warm and deep.
Brightness: Brightness numbers from manufacturers will mean little because they aren’t measured under real-life conditions. Your own viewing area will play into this considerably. LCD TVs have the reputation of doing slightly better in bright-light conditions.
Black Levels: Plasma TVs generally produce very black blacks whereas an LCD TV will produce a very dark charcoal gray. The very dark gray that LCD TVs produce is sufficiently dark for most people. Many would take it for black if not told otherwise.
Contrast Levels: Plasma TVs, technically, are known to have greater contrast levels than LCD TVs, however many see LCD TVs as being more vibrant, which seems connected to contrast, at least in the mind of most viewers.
Cost
LCD TVs are generally a little more expensive than plasma TVs when talking about the larger sizes. Prices for both, however, are coming down rapidly.
As for which brand to choose, the top brands I believe are sony, LG and samsung in that order for LCD tvs. for more info go to
