![]() Also, more lights mean more internal parts, and each segment of lights has to be carefully engineered for maximum performance. All those LED backlights take up more space in the TV’s body, so it’s going to be thicker. The trade-off on full array is usually price and aesthetics. They make for a tremendous theatrical experience. It should come as no surprise that film buffs and gear heads love full array backlit TVs. The result is that most of the cave will still appear inky black, but the black areas close to the torch might appear less, well, inky.Ī scene like this is a great example of how full array backlit and edge-lit TVs might differ How does this impact wallet? It’s just not quite as exact in its localization, because the LED lights live on the edges of the panel. Many edge-lit TVs also have local dimming. ![]() It can turn up the brightness on just the LED lights directly behind that part of the screen where the torch is. The TV now has to make a choice about how to balance these two opposing needs: bright in the center, dark around the edges.Ī full array backlit TV has an advantage. Both kinds of TVs would lower the brightness of the LED lights to make sure that cave looks inky black.īut suddenly, our hero of the movie enters carrying a torch that lights up the center of the screen, while the darkness of the cave presses in on her from all sides. The scene takes places in a deep, dark cave. Imagine you’re watching a scene in a movie. Is still very thin, but edge-lit TVs get even thinner if you can believe it. That means a 55-inch screen TV has a matching 55 inches of high quality LED lights. Rather than just lining the perimeter, full array backlit TVs have a complete grid of LED panels behind the screen. Edge-lit TVs are the thinnest LED TVs you can find, which is a big plus when it comes to looks. LEDs are placed on the perimeter of the television panel (usually the top and bottom). The simple differenceĪs the name suggests, edge-lit TVs are lit from the edge. So let’s dig into how these TVs are actually put together. Well, as any engineer worth their salt will tell you, there are always trade-offs. So why isn’t every TV that thin? And why are the really premium TVs sometimes even a little thicker? That’s because LEDs are extremely small compared to a bulb, which has allowed TVs to get razor thin-sometimes thinner than a pencil. You can appreciate LED lighting even when the TV is off. They’re brighter, more energy efficient, they don’t get as hot, and the quality of light is much better. Today, however, nearly all TVs use LED (light-emitting diode) lights. Today’s TVs have better picture quality than ever, but without some kind of lighting inside the TV there wouldn’t be any picture at all! That’s why most TVs have an array of thin, high quality lights built into the sides or back of the TV panel.Ī few years ago flat panel TVs used skinny fluorescent tubes, not that different from typical office ceiling lights. Their slim profile makes them the ideal elegant LED lighting fixtures for offices, hospitals and schools among other commercial and industrial LED panel applications.This article is sponsored content and was written in collaboration with the sponsor. The distance between each individual SMD can be adjusted to give various light intensities and uniformity, thus provides precise light control, uniform shadowless light and high optical efficiency in general lighting applications. The same concept is used in the direct lit LED panels, so lesser LED’s are required in this type of panels when compared to other lighting technologies like edge lit panels and CFL lights.Įdge-lit LED panel lights place the LED light sources at the side of the panel with light beaming into a light transmitting/guiding medium that re-directs the light to the viewing surface. But at the same time it is using the same amount of energy whereas brightening sizably a bigger area. This is similar to a torch light when you flash the light on a wall from a short distance the light spot is smaller but as you move away from the wall the spot gets bigger illuminating a larger area. The light will project light forward across the full expanse of the light panel from the front. Such lights are called direct-lit or back-lit panels. Direct-lit ceiling panels work by placing the LED light sources at the back of the panel.
