Dolby Delivers High-Dynamic-Range Technologies for Improved Contrast and Brightness for LCD Displays With LED Backlight Technology
Dolby Laboratories, Inc. (NYSE:DLB) and SIM2 Multimedia are proud to showcase 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 utilize the capabilities of LED-based backlight units (BLUs) to provide outstanding contrast combined with crisp brightness to deliver picture quality that matches real-world visual perception of depth, detail, and color.
“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 with Dolby’s HDR LED backlight technology:
- 1,838 LEDs
- LCD panel providing a resolution of 1920 x 1080, fitting a native 16:9 aspect ratio
- Brightness: greater than 4,000 cd/m2
- Contrast ratio: Infinite! Full On/Full Off
- Step size: 16 bits of luminance
- Luminance uniformity: 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.
This prototype sports a contemporary and stylish design, befitting the most diverse of home interiors; it is a new masterpiece by the award-winning designer Giorgio Revoldini.
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.
