Dolby Laboratories, Inc. (NYSE:DLB) and SIM2 Multimedia have prototyped a high-dynamic-range (HDR) LCD flat-screen display using a Xilinx Virtex(tm) field programmable gate array (FPGA) chipset, which was 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.

The 46-inch LCD design uses 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.

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.

Prototype Features

  • 1,838 LEDs
  • LCD panel providing a resolution of 1920 x 1080
  • 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
