Comparison of 42 inch LED TVs and LCD TVs


The market of television today, there are actually two types of LCD TVs. One is the standard or traditional, LCD while the other is the latest retro-LED LCD TVs. The latter are called LED TVs for brevity, but it is more accurate to call the LED-backlit LCD TVs.

Both use the LCD display or ubiquitous liquid crystals. This is the same display used in digital watches.Quite simply, an LCD Panel is an optical device, usually with a flat thin, which displays électroniques.Il information consists of miniature liquid crystals which form the pixels, which are then assembled in a table to produce an image points.

A LED 42 "and a LCD TV standard for this type of view." What differentiates them is the rear lighting or lighting behind the display. In the 42 TV "LED back lighting comes from light emitting diodes (del)."On the standard LCD, the back light is provided by fluorescent lamps of cold cathode (CCFL) .CCFL look like ordinary fluorescent, less startup time long flicker.They light up quickly because they are able to start in cold, hence the "cold" in the acronym CCFL.

LEDs are much greater than CCFL producing images.ainsi, a 42 LED "has a better quality image that an LCD standard.La variation is particularly obvious when the image has portions contrasting black or very dark parts and items more légers.Dans a 42"LED, the dark parts be genuinely black deep, while in TV, they will appear as richly or black accurately.""

Apart from offering the best contrast and color saturation, a 42 "LED TV is better because of its more efficient use of energy and thinner generation."
