An LED Television is an LCD television that makes use of light-emitting diodes for the purpose of illuminating the LCD display. The LED technology was formerly used just for accent lighting, but today they have emerged as a feasible option for lighting applications in HDTVs. LED is short for light emitting diodes, which can convert electrical energy into light of a single colour. There’s no waste of energy in the form of heat, as the technology used is cold light generation.
LED technology isn’t actually a new television technology, but just a different way to light up the LCD. The competition in HDTV today is between LCD and Plasma. Creating true black with the LCD TV is tricky, as the light is perpetually on. However even if the light is prevented from shining, some light bleeds thru to reduce the black. LEDs can fix this problem and are becoming very popular in HDTVs and ps3 xbox gaming setups. They are smaller in comparison to the Cold Cathode Fluorescent Lamp that was previously used on the back of the Television as a back light. LED can be employed to use less energy and produce less heat, thus lengthening the life of the HDTV. The quality of the picture will rely upon the sort of LED lighting that’s employed.
Deep blacks can’t be created by LCDs and this decreases the image sharpness in the HDTV. The color saturation is also limited in an LCD TV. Nevertheless when LEDs are used to light up the display, they are placed on the back of the display or around the perimeter. The second method is often known as the edge lit display. The power used in this case is also less than that utilized by standard plasma and LCD televisions that are lit with fluorescent tubes.
As the LED sources are on the side, the HDTVs using them can be ultra-thin. They’re also more cost-effective than the LCD televisions that use the LED backlit technology. On the other hand, the TVs that use LEDs at the rear of the display have got the edge in that sharper and deeper blacks are created. This is down to the fact that of a method known as local dimming.
When a dark image is required on the screen, it is possible to fully shut off the LEDs in the area, so that black looks entirely black without any light dribbling into it. The LEDs can be integrated into a control system and may also be powered from a battery pack that’s transportable. They are also very small and compact in size and are resistant shock and vibrations.
