What kind of TV

Current TV on the market will have different types of screens available. They have a model that works differently but for the same purpose. That is, the image displayed on the screen sharpness. Most virtual Each technology has its good points, it is a weakness in itself. What will we consider in buying a TV are just preliminary.

LCD TV: CCFL

Mobile TV is an LCD backlight is older fluorescent fluorescent open all the time. This technology is getting old May not be sold because there are new technologies such as LED replacement but may also be found in some cheaper LCD TVs.

LED TV: Edge LED

LCD TVs are LED bulbs installed in the area of ​​the screen. The layout makes the screen thinner and the difference of contrast (Contrast) to better monitor the CCFL early, but the picture was not as good as a Direct LED, however, the television series is. low cost makes it cheaper. And that is why this LED TV will look like this illumination.

OLED TV

The illumination of an Organic LED TV is done by passing an electric current to the thin film that emit light out. This technique will provide a color display is bright and also very thin. Is the ultimate in display technology today. And just started this year on a large-screen OLED started putting the market. It is a new and expensive brands are trying to do this in the market.

Plasma TV

Plasma-screen TVs that use glass plates sandwiching a million cells a small cell with inert gas contained. When an electric field to induce gas will make it to emit light at the pixel position in principle, LCD Plasma is better than LCD displays in terms of brightness and color accuracy. But only the big screen only. And now, many companies have gone out of production. It has sold probability of surviving, which is found with the same size will be much cheaper than LED screens.

Curved screen TV

The principle that will make every pixel on the screen away from your eyes, in the distance as well. Making the image more realistic. However, the downside is. If you sit near the coast or one too. The curvature of the screen to make the image look distorted.
