JVC announced at InfoComm 2007 a 1.27-inch 4K2K D-ILA chip for use in projectors that offer up more than four times high-definition resolution. Intended initially for medical, modeling, and simulation use, the chip can produce a ten-megapixel 4096x2400 pixel image with a 20,000:1 contrast ratio. While DLP-based 4K projectors are currently in use in some digital cinemas, the JVC chip will be used in D-ILA, a variant of LCoS (Liquid Crystal on Silicon), and has a higher pixel density. Much like professional racing technologies trickle down to the average sedan on the street, the research that goes into 4K projectors can also make their way to HDTVs in the home, bringing smaller, higher-definition sets to a living room near you. We say bring on the quad-split-screen HD!
Televisions/video displays have to be the fastest evolving technology ever. This thing is as tiny as a quarter... Now if it only cost a quarter to manufacture we'd all be in luck!
great, but where's the content coming from?
the only that may be able to use this is a really high end PC upconverting HD videos and playing games at deadly resolutions
who cares about content that High Def at the consumer level... imagine the computer displays. HD video playing in a window while surfing the web and messing in photoshop... all on the same, very large desktop.
Correct me if I'm wrong, but isn't this only ~2.4X HD, not 4X? Hd is 1080 vertical lines of resolution, this is 2400. The 4096 is the horizontal resolution...
Yes. 2.4x the vertical resolution ... but you aren't accounting for the gained horizontal resolution. They don't just make it taller, they make it wider. It is 4x the pixels.
2x vertical times 2x horizontal = 4x in both dimensions ;)
There are actually 4.74 times more pixels.
1920 x 1080 = 2073600 pixels
4096 x 2400 = 9830400 pixels
9830400 / 2073600 = 4.7407407407407407407407407407407
Ah, of course. Must not have been thinking straight last night.
I saw this at InfoComm today and I must say, it was probably one of the most impressive items at the show.
Does someone have the top secret industry info about how expensive it is to build a 4K projector/TV compared to building a 1080p projector/TV?
I tried to figure it out once there was the industry upgrading from 720p to 1080p, and I was talking to an engineer at a famous screen manufacturing company, that the cost difference between 720p and 1080p is just about 25-30 dollars. IS there a same cost difference in manufacturing 4K instead of 1080p?
Cause I think some people might like to know before investing in a 1080p projector or screen if there could be a 4K projector/screen made for 30 dollars more. But that it may just be a industry strategy first to sell out 1080p and wait patiently before releasing and manufacturing 4K technology.
I have seen 4K TVs at tradeshows, and it's simply totally amazing. Though 1080p is kick ass awesome also.
