Dolby Laboratories’ High Dynamic Range (HDR) LED local dimming technology came one step closer to commercialization yesterday, as SIM2 Multimedia, in conjunction with Dolby, took the wraps off the world’s first high-definition LCD TV prototype to embody it.
The 46-inch prototype, referred to by the companies as a “working demonstrator,” used a 60Hz LCD panel. It is not yet slated for introduction but is rather “a platform” that was presented, according to Dolby’s senior marketing manager for HDR, Bharath Rajagopalan, to showcase the ability of HDR “to deliver crisp, bright images using advanced algorithms for subtle detail with deep contrast and high dynamic range.”
Domenico Toffoli, director of the Professional Systems Business Unit at SIM2, explained that while Dolby was responsible for engineering the processing on the display, his company developed the backlighting unit, the electronics driving it and the thermal management system. SIM2’s Marco Rampin, senior engineer for R&D, added that the backlighting on the LED array consisted of 1,838 standard white LEDs.
