Dolby Showcases the Future of HDTVs With New 46" HDR LCD TV Prototype


Dolby Laboratories and SIM2 Multimedia showcased a new prototype high-dynamic-range (HDR)-enabled LCD flat-screen display using Dolby's new light emitting diodes (LED) local dimming technology.

Dolby?s HDR technologies leverage LEDs with local dimming to provide dramatically enhanced contrast combined with crisp brightness.

"This prototype is a stunning example of what Dolby's HDR technologies can bring to the LCD market," said Bharath Rajagopalan, Senior Marketing Manager, HDR, Dolby Laboratories. "We welcome the opportunity to showcase our innovative technology that delivers a dramatic improvement to LCD displays."

As part of the collaboration effort, SIM2 designed and developed the BLU, which drives the electronics of the LCD display plus the BLU and BLU thermal management system. In addition to the prototype development, SIM2 will provide Dolby with manufacturing reference designs.



"This prototype exemplifies SIM2's ability to incorporate breakthrough technology into its electronics and optical design, providing--once again--a stunning display that will be a key reference for next-generation LCD displays," said Domenico Toffoli, Director, Professional Systems Business Unit, SIM2. "We are proud to be the first to support the development of a technology of this stature."

The prototype is a 46-inch LCD features 1,838 LEDs, supports a resolution of 1920 x 1080, fitting a native 16:9 aspect ratio, a brightness greater than 4,000 cd/m2 and an almost infinite contrast ratio, according to the companies. Notice that current LCDs offer a brightness of some hundrends of cd/m2.

The prototype also offers an overall luminance uniformity of more than 95% through the LCD panel.

Incorporated into the design is a Xilinx Virtex field programmable gate arrays (FPGAs) chipset, recently approved by Dolby for HDR innovations. The Xilinx FPGA chipset enables the implementation of Dolby's complex high-dynamic-range algorithms in the SIM2 display.

Dolby and SIM2 are showcasing the prototype in New York City today and will be sharing its latest LCD display innovation in cities around the world. SIM2 and Dolby are on schedule to unveil the prototype display in Q108.
