When LED-based displays first hit the market, they were backlit by a full array of LEDs behind the LCD and across the back of the panel. But to create a thinner LED flat panel TV, engineers have had to eliminate that extra layer and move it over to the sides of the display. This backlighting means that the lights are affixed to each side of the set and that light is projected inward toward the middle of the box.
Most of these products feature a technology called local dimming. With local dimming, parts of the backlight can be brightened or dimmed independently when different parts of the picture get lighter or darker. This helps reduce the amount of light that can leak through to darker pixels. The result is a much more realistic picture with outstanding colors. Images tend to be crisper too.
The main benefit to an edge-lit LED flat panel TV is that screens have gotten thinner and thinner. BuyDig.com offers the latest options and brands at highly favorable prices in a range of sizes from 32 inches right up to 84 inches.
Unlike plasma screens, backlighting on these models is even more efficient than the standard fluorescent counterpart. It helps cut down on power consumption, and some models are, inch for inch, the most effective products on the market.
On average, an LED flat panel TV will use around 101 watts, compared to 111 watts for standard LCD models. Although screen size and picture brightness can affect power use, even the biggest screens will render noticeable annual savings.
Manufacturers are continuing to improve backlighting and flat panel units and other features, and soon there will be edge-lit technology available.
For hardcore viewers, the 70 inch LG model offers smart functionality, a motion clarity index of 960, and a refresh rate of 120Hz. The unit is edge-lit with local dimming and comes with a Magic Remote and two pairs of 3D glasses. Triple XD on this product makes for incredible color and clarity.
