At CES, JVC demonstrated a rear projection D-ILA set with a 2.35:1 aspect ratio. This is a first, and a taste of future trends in rear projection. For that matter, if they tooled up to make three 2.35:1 LCoS chips, they are probably planning on releasing a product at some point. There may also be a 2.35:1 front projector in the works. At CES, they also showed a 3-D rear projection set, and a 1,000,000:1 contrast ratio LED D-ILA rear projector. JVC is really being innovative.

Cinema Wide HD-ILA

With an aspect ratio of 2.35:1, JVC's prototype Cinema Wide HD-ILA offers enhanced viewing of DVDs and high definition movies. Most widescreen movies are distributed in this 2.35:1 aspect ratio, while current widescreen TVs have a 16:9 (approx. 1.78:1) aspect ratio. JVC's Cinema Wide HD-ILA displays 2.35:1 content properly without letterboxing.


It can be seen in the background in a photo (just before the "No Cameras" sign!) in this report (thanks to HDholic):

Quoting from that article, it appears that real sets may be on the way! Sign me up for the big one!

"In an area closed to photos, JVC also showed some possible advanced technologies. The one that caught my eye was a rear projection HD-ILA set with an aspect ratio of 2.35:1. They even postulated three different screen sizes. While there are no announced plans for production of such a set, the suggestion of three sizes certainly suggests that someone is thinking about it."


Comment from Tryg in the High End Front Projector Forum:


"JVC had some other interesting items like a 2.35 rear projection unit., and a 3D rear projection unit that you can play cheap videogames on and it looks incredible. Madden 07 on this thing was unbelievable. You feel like you are actually on the field."

Comment from Peter in the FP forum - confirmed by JVC that the 2.35:1 set uses the killer optical engine (wire grid polarizers, 15,000:1 native CR with a bulb) of the DLA-RS1:

"After viewing the HD-1 and Pearl setups, I happened to look at this set for a couple of seconds. A very, very, polite and gracious JVC rep proceeded to give me a spiel on this set. His english was not the best but he was trying very hard. What I learned was that the projection system inside consisted of the HD-1/RS-1. This was just a prototype and had no definite release schedule. I got the impression they were gauging interest..."


Earlier, in this RP thread, someone commented on a JVC wide screen CES demo, but got his notes mixed up and thought it was 1.85:1. Now clear it was a 2.35:1. It's on post #20 of this thread:

Note that a 2.35:1 RP set would want to be on the big side if SD and 1.78:1 content wasn't too be too short. The screen dimensions at various diagonals are as follows:

65": 25.5" x 59.8"

70": 27.4" x 64.4"

76": 29.8" x 70"

80": 31.3" x 73.6"


It takes an 80" Cinema Wide to provide the approximate screen height of a 65" 16:9 set. I would love to be able to buy an 80" in a slim wall mount.

iif this goes into production the consumers would be trading bars at the bottom and top for ones on the sides. unless you watch cinemawide exclusively

I like the concept. It has the makings of a hit and the future. JVC is coming back with a bang in a big way this year. First to hit native contrast of 15:000 to 1 with a digital PJ. First to introduce a 2.35:1 RPTV and perhaps the first to introduce a 3-D set. Bravo! Wonderful!

Let's see who is the first one to introduce a 2.35:1 curved flat-screen plasma / lcd! That will be a sight to behold for the sheer aesthetics alone.

So I wonder if they have built a special 2560 x 1080 chip or simply used 810 vertical pixels of the 1920 x 1080 chip?

I think it is very possibly theat they are using a standard 1920x1080 chip and using a different lens in the light engine optics to get the different aspect ratio.

 

[Kevin McCarthy]

I'm betting it's a dedicated 2.35:1 LCoS crip trio. If you read their white papers, they have done perhaps a dozen different chip formats in the last few years. Rolling another one wouldn't be that great an investment. The comment about "three screen sizes" strongly suggests that this will show up as a product family, I would guess around year's end.


EDIT: Just noticed the comment from JVC (in my own post) that the engine inside the Cinema wide set was that of the HD/RS1. My comments above are probably wrong, and it is lens based as per Walford.


Does anyone have any data (as opposed to speculation) on the percentage of 2006 releases in 1.85:1 vs 2.35:1 OAR?

 

[Logansneo]

In theory the ideal setup for a 2.35:1 HDTV would be using an OLED flat panel mounted flat to a wall (similar to Sony's OLED demo's at CES) but then you wouldn't have the flexibility of using a lens to throw the image onto a 2.35:1 screen, and would have the chore of developing a 2560 x 1080 based flat panel with some custom circuitry to interpolate a 1920 x 1080 image to fit.


If JVC does produce these Cinema Wide HD-ILA displays I'll be first in line!

I agree with bender wholeheartedly.


Imagine watching HD programming on TV (including prime time shows and sports broadcasts) now with the freaking black bars on the left/right. You'd only make real use of this wide aspect view using 2.35 AR HD-DVDor Blu-Ray movies.


Geez, and imagine how big the side bars would be when viewing SD...

Saw this thread, was very intrigued and had to check it out.


A 2.35:1 TV screen does sound very cool. But, I gotta concur--Essentially ALL broadcast HD is around 1.78:1. And it seems a large portion (if not the majority) of "widescreen" movies are in the same or similar ratio (1.78 or 1.85:1) compared to their wider counterparts. There are some films (SEVEN, MINORITY REPORT, ROYAL TENNENBAUMS come to mind) that are even shot in 2.39 or 2.40:1 ratios. So those ratios will still have some very slight horizontal black bars (albeit small ones) unless they got overscaned out.


And there's still a lot of 4:3 stuff out there. Huge black pillarbox bars on those.

Guess the black bars on my HD screen from a 2:35:1+ movie just don't bug me.

Now this is as close to scale I was able to put together with XP paint. I have a comparison below of a blow-up I did of the actual prototype in a background shot from CES 2007.
