Gennum and JVC Make Significant Advancements in HD Projection Chips
The newly developed 1.27-inch (approximately 43 percent area reduction) 4K2K D-ILA device chip offers 4096 x 2400-about ten megapixels-and a 20,000:1 contrast ratio.
Gennum Corp. another major player in the fast-moving HD projection market, is showing an image processing solution and reference design to drive 4096 x 2160 pixel displays.
While previous industry demonstrations of 4Kx2K have used custom processing solutions, often utilizing multiple field programmable gate arrays (FPGAs) to manage the complexity, Gennum’s new 4Kx2K reference design incorporates two of its GF9450 image processors to power the display.
The GF9450s, powered by VXP technology, provide full motion-adaptive deinterlacing, professional quality scaling up to 4Kx2K, frame rate conversion and various image enhancement technologies such as 3D noise reduction, compression artifact reduction and detail enhancement.
The low power of the GF9450, under 3.5 watts, is also key to emerging 4Kx2K displays as it will eliminate the need for a fan to cool the device. This makes it possible for Gennum’s technology to be incorporated into the small footprint of flat panel display electronics while delivering the processing bandwidth and image quality expected of very high-resolution displays.
Gennum said it will have a single chip solution for 4K displays by the fourth quarter of this year, which would enable new projection products based on the design to be available for sale by the second half of 2008.
