Xilinx FPGA Chipset Powers HDR LCD Flat Screen Display

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.
