SIM2's Local Dimming II

In addition to its line of projectors (which was heavily featured at the 2007 CEDIA Expo), SIM2 has begun working with Dolby to incorporate new Dolby video technology into its LCD flat panel displays. This technology involves LED backlighting with local dimming to improve black levels. The demo in the SIM2 room (and also in the Dolby booth) was set up to show not only the original image (in the previous post), but, with the flick of a switch, the lighting pattern of the LED backlights (shown here). According to SIM2, their prototype uses 1300 LEDs.
