Since this is a local dimming LED display, it would make sense to discuss how well this works in combatting LCD's traditional contrast limitations. The answer is: somewhat well.
When you’re on-axis (that is, not watching the screen from the sides), the effect is at its best. Dark areas of the screen are somewhat dark, with noticeable but largely unobtrusive light spill from surrounding areas. Remember, there is a limited number of LED lights behind the LCD screen: each pixel does not have its own corresponding LED light source but instead must share it with surrounding pixels, so this so-called halo effect can occur (see image, right). From the sides, the usual LCD issues of decreased contrast and shifting gamma are visible to a minor extent, except when those areas are totally black (because the LEDs for those portions are shut off). It’s also worth noting that the LED lights take a small amount of time to react to changes in brightness on the LCD panel, so the effect is not entirely seamless. With all of those quirks noted, keep in mind that my reference is with Plasma display technology, which is still the current flat panel state-of-the-art. When compared to conventionally backlit LCD TVs, local dimming LED is superior.
