Full Array Local Dimming
When it comes to stunning picture, Full Array Local Dimming is the crème de la crème of the LED world! Learn more about LG Full Array LED Backlight TVs.
Whether you’re watching ultra-dark scenes in a gripping movie, a video game, or in your favorite TV shows, being able to see all the details is the key to experiencing your entertainment the way it should be experienced. But what you may not realize is that the technology behind your television that makes it possible is Full Array Local Dimming (FALD)—and it can mean the difference between just watching, and really immersing yourself in it. But, what exactly is Full Array Local Dimming, and how does it improve your LED TV?
Full Array Local Dimming 101
Before we get to Full Array Local Dimming, let’s take a step back and look at the other types of LED TVs out there, which are Direct Back Lit and Edge-Lit.
Edge-Lit: When you hear the term Local Dimming, it's usually used in reference to Edge-Lit televisions. In these TVs, the LED lights sit around the perimeter of the screen, with each zone dimming as a group in an attempt to improve contrast. In general, they do a fine job of creating contrast, but the lights are unable to dim individually and they lack the richness and depth of FALD TVs—and depending on the quality of the television you choose, their color and contrast levels may not be evenly distributed.
Direct Back Lit: Today, Direct Back-Lit technology is generally available on older or entry-level televisions. It uses a small amount of LED lights behind the screen, which work to light the picture. However, because all of the contrast depends on just a few lights, dark scenes can end up ALL dark and light scenes look TOO light, which means that contrast is negligible at best and whatever is on the screen won't come close to a true-to-life image. Some very low-end Direct Back Lit TVs offer no local dimming at all.
For the most part, Edge-Lit televisions have replaced Direct Back-Lit TVs, but you can still find some new ones at a good price, if you're interested.
TVs with Full Array Local Dimming technology have multiple zones throughout the display and—unlike TVs that have LEDs around the edges of the panel—these LEDs are instead placed behind the screen, like the Direct Back-lit TVs… but that’s where the similarity ends. Full Array LED backlighting delivers hundreds of different LEDs, resulting in light levels from many separate zones. Thanks to these independently controlled light zones, you see enhanced black levels, better shadow detail and a decreased level of “light bleed”—which can occur when the light is not completely blocked, allowing excess light to "bleed" out around the edges of the panel and creating areas that are too light on a dark background. With light bleeding decreased, you get greater contrast and superior picture quality, while enjoying enriched colors and life-like images for a true home-cinema experience. And while Edge-Lit Dimming improves picture quality to a point, Full Array Local Dimming is the crème de la crème of Local Dimming technology—which has never been more important than in today’s high dynamic range (HDR) TV realm.
How does Full Array Local Dimming complement HDR and other advanced TV innovations?
Full Array Local Dimming backlighting reveals a remarkably accurate picture with dazzling 4K detail, while state-of-the art technology, like LG’s α7 (Alpha7) Intelligent Processor, works in tandem with the Nano Cell™ Display to deliver truer colors, deeper black levels and a wide viewing angle. Add to that comprehensive support for major 4K high dynamic range (HDR) formats, including premium Dolby Vision™, HDR10, HLG, and Advanced HDR, not to mention Dolby Atmos®, and you’ve got an immersive audio-visual experience you have to see to believe.
