: one thing that makes the LCD TV coverage so interesting is that the technology is advancing ever and an innovation that could be the biggest yet, local dimming LCD. But you're probably wondering, what is it exactly? Well in non-edgelit LED LCD TV, there is an array of led lights behind LCD pixels and local dimming is when sections of LED matrix are disabled or gray to help produce the deep blacks--as Kuro deep. But while this technology can produce very deep blacks and fantastic contrast, there is a problem, even create an artifact as a Halo around bright objects. Example: the two images above are opening scene of The Matrix (cops that shines a light flash) is pretty easy to say that is the plasma and LCD LED with local dimming. Of course we don't exactly watching movies with lights flash or fields stars every night, so after the break are multiple images of a dark scene also normal that expose the artifact caused by local dimming (we must emphasise that the camera makes more drastic than it looks in reality). So while we don't buy an LCD without local dimming, there is still much to look forward in the next generation when the dimming is sure to become more local, and so will be minimized the artifact. At the same time that these advances should help produce more detail in neri, which is harder to notice at first, but just as annoying, once you have.Just enter in HD? check out these other features HD 101:
