TV LCD a LED

The great variety of products available among the LCD TVs in fact allows the user to choose between offers virtually limitless, which differ not only technical but also for the individual producer price range.

Beloved by consumers for the undoubted advantages of technical and aesthetic (especially compared to the old color TV picture tube), LCD TVs have reached another milestone towards an ever greater perfection: the LED backlight.

Normally, the LCD TVs on the market today have a backlit with neon: the use of LEDs greatly enhances the performance of the TV and, in many respects, it is also more environmentally friendly. Within the screen, the light produced by LEDs of red, green and blue merging to produce a brilliant white light. This light passes through a slab that serves as a speaker, then to become uniform on the screen. The result is a very vivid colors, extremely sharp, high-quality higher than that of a normal LCD TV, in which the light produced by neon is not as white (it turns into red, blue or green ) and, therefore, must be “correct.”

The LED also produces much less heat than the neon lamp: Avoid overheating problems, and product quality salt for that too. The LED does not contain toxic substances like mercury and high pollution, and in some cases allows an energy savings of 40%, eg in the case of LCD TV Samsung LED recent production, the 40-inch models provide a consumption of 140W in use and only 0.1 watts in standby mode. Picture perfect, low consumption, TV built with a particular eye to aesthetics and design, but … and costs? Still quite high, for the truth, but destined to fall in the near future.

The LCD backlight with LEDs seems to really present himself as the standard of the future, and its increasingly wide distribution will result in an expected increased availability of models and a leveling of the final cost.
