It was not too long ago when deciding which TV to buy meant choosing between plasma and LCD TVs. These days, a newer technology has emerged and is gaining a strong foothold in the TV market: the 42" LED TV.
LED is acronym for light emitting diodes. This is the backlighting technology in 42" LEDs responsible for their very high contrast ratios, true blacks and brighter colors-characteristics that give them an edge over standard LCD TVs. It is the technology responsible for the longer lifespan and more efficient energy use of 42" LEDs, making them better than plasma TVs.
After LED, the most advanced TV technology is OLED, which stands for organic light-emitting diodes. OLEDs do not require a backlight to function; instead, a thin organic film is directly transferred to the surface using a simple printing mechanism. There are OLED TVs out in the market today, and they are stunningly thin and have unsurpassed picture quality. However, their prices will also cause one to do a double take. This makes OLED TVs an impractical choice for most people, even though they are first-rate in the technology department.
All things considered, the top choice then becomes the 42" LEDs. These dominate in terms of picture quality, energy efficiency, lifespan and dimensions.
Compared to standard LCD TVs, 42" LED TVs give better pictures overall. They have deeper blacks, higher contrast ratios and more vivid colors. They also deliver better viewing angles, and are longer-lasting.
In terms of energy consumption, 42" LED TVs are the most efficient, easily beating both LCD and plasma TVs.
And last but not least, what is so fascinating for many people about 42" LED TVs is how slim and light they are. Some 42" LED TVs are only an inch thin, therefore easy to handle, move around, or mount in walls.
