Could rear projection doom front projection?

JVC just showed a 110" rear projection DLA . :eek: This is larger than many peoples front projectors. Would there be many good reasons to have front projection if you could by a rear projector the same size for about the same price?

cant wait to see a 14' wide 2.35 rear projection unit at best buy!

I can see it now..Arts next theater meet. Its show time and the curtains open...


I cannot see anyone with a dedicated Theater room putting one of these up on stage but they do indeed have their place. I do not see them as a threat to FP but it is indeed great to see them getting bigger and thinner and the price for these RP are dropping :)


I agree with tryg. Give me a 235:1 set and Im all over it. I would put one in the kitchen:)

In my case, my screen is going in front of my sliding glass doors. There is simply no way to put a massive rear projector in front of the doors. Plus, how would you put these massive rear projectors anywhere? They're terribly heavy. Front projection seems to be an easier proposition, in my opinion.

It is easier to mount a projector in the ceiling than to move a 110 inch monster through your house.

I find Optoma´s Bigvizion concept interesting. They offer a 100 inch model. Why not just shorten the room and put up a new wall. This could be the choice for future media rooms.

Yes. Several reasons, in fact. And most of them are related to flexibility, which in a dedicated HT install is a big deal.


1) You pick the screen, which has several sub-impacts:

a) You decide the gain

b) You decide the extent to which you're willing to deal with annoying screen sparklies

c) You decide the viewing cone

d) You can get an accoustically transparent screen if you want, which allows you to mount your speakers behind the screen


This reason alone will seal the deal for many. I for one did not want to buy an SXRD RPTV, partly because of the annoying screen speckle. And many HT seating arrangements simply cannot tolerate the viewing cones of common RPTVs, which tend to have high gain screens.


But there is also another reason. A front projection system, with its giant wall mounted screen, just looks more like a real theater. And you can mount it to a false wall and hide your speakers behind AT fabric.


RPTVs are mass produced items designed to operate in Joe Six Pack's multi-purpose Den. Front Projectors are much more suitable for a dedicated HT.

A projector's light beam and that great picture on the screen... naw I'd never be happy with rear projection.

Without a doubt they are getting thinner, lighter, larger. I can see these killing off the plasma market sooner or later.


Staying some what with the topic Im sure we will see the day where we unroll a solid sheet of organic material ( Id prefer 235:1 in my case ) and mount it to the wall just like a screen. This would have some input wires running out of the corner we would run across the room to our equipment rack for connectivity. Possibly driven by OLED or another technology with great contrast and black levels. No more projector mounts and worrying about throw distance :)

Ohlson,

I was thinking of you today when my business partner called me from Houston. He was at the Mitsubishi Road Show. He said they spent part of the presentation talking about their new 4" deep, 100" diagonal LASER rear projection TV!! :) They said they are skipping LEDs and going straight to laser, since they feel it is the future.

And which price are you referring to, $5,000 or $50,000?

Does this mean no SSE?

Help me out, what is SSE? By the way, their stated philosophy was to produce a large enough quantity that they could have a "competitive price". My partner asked about $25k and the rep said, no they would like it to be in the teens, since they don't really intend for it to be ultra exclusive, like they did with their 82" LCOS of yore.

SSE is silk screen effect, or a shimmering effect on RPTV screen surfaces similar to that seen when light is projected through a thin silk screen. This is due, I believe, to characteristics of the screen that provide gain. It can be seen particularly on bright images. For some it is of no concern, for others it is distracting.


My question was based on an assumption that brighter light sources would need screens without or less gain, resulting maybe in less SSE. Such a screen might be less directional.

SSE is also made worse by the ant-glare screens that are found on most DLP and LCD rear projection sets nowadays.

Unless they eliminate the viewing cone for RP displays, I cannot see how these sets would kill off the plasma market. The biggest selling point for plasmas is that they look the same at any angle, whereas RP sets do not. What might kill off all sets are the SED sets from Toshiba and Canon (IF they ever get to market).

Nothing is killing off anything. SED optimstically is targeting about 10-20% of the 50+ inch flat panel market over the next 5 years. It has about as much chance near term of killing plasma and LCD as either of those has of killing off the other. Technologies do die off, but rarely overnight. Plasma and LCD are both cooking right now and will continue to do so.


Room-slicing RPTVs -- whether Optoma's that entail a wall or gigantic self-contained boxes -- are unpopular and/or not practical for most people. In a pre-existing multi-purpose room, virtually no one can implement BigVision and a self-contained giant box is the very thing we got rid of for flat-paneldom.


I have no idea if Mitsubishi can build a 100-inch RPTV that is 4 inches thick, but I think it's no coincidence that they aren't looking at 60 inches. Flat panels are going to continue their inexorable march to eliminating projection displays from the small end of the market. Front projectors are going to continue their steady growth into more homes as the only practical way to get a 100-inch screen for some time to come.


Like Alan, I want to roll out my OLED and have a gigantic, lightweight, projector-less display that requires no picture-quality compromises. I'd be very surprised to see such a thing available by 2015.
