REVIEW: Samsung LE-52F96BD Part 8
With the LED backlight, the light is created by white LEDs. A diffuser plate ensures that the LCD panel is evenly lit.
With LED backlighting, separate control of the individual lamps makes it possible to switch off the backlight for black image content whilst bright areas of the image are still brightly lit. This technology is called "Local Dimming". Thus, a contrast ratio and black value level can be achieved which has otherwise only been possible on tube televisions to date.
The black value of the Samsung LE-52F96BD is 0.001 cd/m², so black is really black and not dark grey. This also increases the reproducible contrast, since the difference in brightness between black and white pixels is extremely large.

According to Samsung, the maximum contrast is 500,000:1. The models in the F96 series are currently the only LCD devices in the world with this technology, named "LED Smart Lighting Technology" by Samsung.
The large LED backlight is also beneficial for illumination and brightness distribution for mono-coloured surfaces. This functions perfectly on the two models of the LE-52F96BD we tested. In the pictures below, the very even display of mono-coloured surfaces is easily seen:
