LED LCoS Next In Evolution?

[AcuDefTechGuy]

Are you guys waiting for the next step in the projector evolution - LED projectors?

So far, I've heard of LED DLP technology.

But what about LED LCoS?

Will JVC LCoS projectors evolve soon to LED LCoS?

Eventually we will see all projectors move to the LED based lighting source. LCoS and LCD will both hit their stride in upcoming years.

LED w/LCoS is already prevalent in the micro/pico projector market with AAXA and Favi using LCoS in their models.

Pretty exciting.

I just saw a 1,000 lumen Samsung XGA projector shown at Infocomm which was right next to a 2,700 lumen projector and putting very similar quality up on screen (LED is scary with how bright is seems to be). Price: $1,300 for a 50,000 hour projector.

It is likely about 5 years before we see LED as more of a norm on most models, but right now, things are definitely headed the right direction, and I'm hopeful that in the next couple of years we will see a few 1080p deliveries under $5K with LED based lighting.

100% light output from hour one to hour 50K is just amazing.

Yeah, I was planning on getting a JVC RS25 next year, but I think I will just keep my Optoma HD81-LV for about 3 more years and get a 1,000 Lumen 1080p LED projector when they come out.

any chance of a laser light based projector, kinda like Mitsubishi's Laservue doesn't use a color wheel or use replaceable lamps?

I think the prospect of LED-based projectors is very exciting, but a friend of mine thinks that the future is in laser-based systems. Certainly the color gamut possibilities with lasers would be very great, not to mention the purity. There are some technical hurdles, one I think would be the 'corpuscular' effect --that granulated appearance that laser light has when it hits the retina and interference patterns result --but I think there would be ways of working that out by slightly widening the spectrum of each primary laser. But certainly, high brightness would be easily achieved with lasers of sufficient power, say 25W or so.

I think if they can do laser technology in TVs, they can do the same in projectors. It's just a matter of time.

Let's hope it gets here in 3 years.

Maybe it will be a Mitsubishi LaserVue Projector?

LED or laser are both technologies currently in use with projectors right now - and at reasonable prices.

But, they are more limited at this time with a focus more on the VERY expensive home theater market (LED) or the commercial market.

Casio, right now, has a hybrid LED/laser/phosphorous projector which is rated to 25,000 hours of use and is around $1,000.

Apparently it is noisy, and the color balance isn't great.

That Samsung XGA model I saw was easily a HUGE product IMO for LED based projection. It was under $2,000 and was far brighter than it appeared. Just moving it into a 720p/1080p DLP chip set would be completely amazing to see happen, and Samsung already has the home theater projector available to drop that light engine into while maintaining the price point.

I think 3 years may be on the long side before we see economically priced 1080p home theater projectors. I expect in about two years we may see some models under $2,000.

I've tested a few of the laser based "pocket projectors" and they show the technology has amazing potential. The AAXA L1 can pull a decent 40" image with the lights down with just 20 lumen. There is the speckling issue that needs to be fixed before you can really produce a theater quality image, but I hear there are fairly inexpensive methods of achieving this being developed.

Laser light is monochromatic and extremely narrow spectrum. In the audio world, it equates with a sine wave from a tuning fork--prone to comb filtering from reflections/cancellations/reinforcements upon recombining.

There needs to be a means to add some spectral noise to the light, so it's less prone to interference patterns (the corpuscular effect).

Certainly, the brightness potential should be good. But the input power will still be high. I'd like to see a good 5,000 lumen HT projector with 100,000:1 or better contrast and 36-bit color. That could be a reality in 3-5 years.
