I want to build a seamless display from multiple LCD panels but in don’t have enough understanding of optics and frenzel lenses to figure out how the lenses should be configured to create a seamless appearance. From my limited understanding the way I would build it is to use 3 lcd's and arrange them side to side with the outer panels bent in at a 15 degree angle and use 3 frenzel lenses to project the image onto a opaque panel like the one out of a rear projection TV. I would like to know how to calculate the distances and angels to achieve the desired affect. Any input would be greatly appreciated.

As I understand it, You want to create some sort of wrap around screen using 3 projectors, which throw images onto 3 screens. \__/ The images will be projected from the back, like 3 RPTVs. What you are basicly doing is building 3 projectors and using a computer to spread the image over 3 LCDs.

My advice is to build a standard front projector first. Everything you learn and all the components and wiring can be reused for your ultimate project.
In the end this approach will probably save you time and money.

When you're ready, you can convert your projector into an RPTV. At that point your RPTV design could be copied and used to create the side screens.
Hook them up to a computer with multiple video cards (or one with 3 supported monitors), and you have the ultimate wrap around gaming station.

Good Luck.

Ok so I did some research and a rear projection setup is WAY TO MUCH work with my current job schedule so I have rethought my problem. My goal is just to remove the seams between the three screens. So I began to think about the old arcade machines with a flat screen and a mirror mounted at a 45° angel. what if I setup the cabinet like this |\_/| with the vertical lined being the two side lcd panels reflecting off mirrors at a 45° angel and the center panel being overlapped by the mirrors just slightly to remove any gap between the displays.

Hi dascreed,

I modified my previous post. (didn't realize you where online). Ya, RPTV conversion are pretty intense. Mine is finally up and running but still needs some fuses and thermal cut-offs.

The set up you just described sounds like putting 3 old style arcades together at 15 degree angles. Is that right?

Yea Basicly well only 2 I was thinking of only reflecting the two side monitors the just overlapping the center screen with the mirrors a little bit to create the look of one really wide monitor

It sounds like it might work but here are some things to think about.

1. If the side LCDs are reflected they will appear smaller than the primary LCD.

2. If the person moves arround then the visual orientation of the screens would not remain cohesive.

Have you thought about just taking 3 LCDs out of their case and putting them together. The edge of most LCDs (without the case) are less than 5 mm. 2 LCDs butted up together would have a band no wider than 1 cm. Using a computer to stretch an image contiguously over 3 lcds in such a configuration might work really well.
