Multi LCD wall

[ujuna053]

Hey guys,
This is my first post but I was wondering if there is any way to make a multi lcd wall display without having those annoying spaces in the middle...in effect i was looking for something like the picture below....looks like some optical manipulations but i dont know how this guy put the displays on this screen (or whatever that material is)

i would venture to say its a rear projection. no matter what type of screen you use, your going to have that (LCD, CRT, DLP, etc.). But if you can project it, then you forget about the constraints of their housings and just bump the projections together on your "screen". Now as far as rear projection goes, i cant help you there, but plenty of people here can help you. I'd say the easiest way would be to find an old busted rear projection tv, gut it, and put in say 3 new "projector" parts in it. Its going to be ALOT of work tho. good luck!

but say i built the three 'projections'.....what kind of material would i use make them 'appear' on the 'screen'

I just came from this trade show in Anaheim California ( almost right across the street from Disneyland ) ... http://www.infocommshow.org/html/

The displays using multiple grids of LEDs and LCDs were everywhere. The secret is in the video display driver for multiple display cards in your computer. An example of this can be seen with any modern Apple Mac that has multiple display outlets. My MacBook laptop has both a built in LCD monitor and a VGA / DVI port for a bigger screen display and it is easy to configure the computer to effectively combine the two displays "seamlessly".

The greatest, craziest, biggest, most fantactic display I saw at this show had 6 big screen, 1080p projectors (2 rows X 3 columns ... 6000 X 2000 pixels), all synced up for a seamless display projected on a screen the size of a very large sailboat sail. The software / driver / video card / projector combination could slowly expand a single projector's image to fill clear to the corners of the array, seamlessly, without hesitations or interuption of the motion. (Imagine the recent movie "Casino Royal", the car crash scene, expanding slowly to fill a screen the size of small drive-in theater screen, the image of the BMW turning end over end while expanding to fill the screen.) ... Anyway, I had a talk with the software author and he said that his "boiler plate" routines were the "simple" Linux GUI routines and multiple display drivers that allow the mouse "throw over" trick between multiple cpu programs and windows and displays. He also said that his software could work with multiple projectors or multiple LCD or LED displays or whatever, VGA type, DVI type or multiple HDMI type displays.

Also at the show were a plethora of multi-segment LED displays, some of which were "wrap around" for use on building columns in shopping malls = the display being, in effect, cylindrical.

The point being that whether with projectors or multiple screens or banks of LEDs, it can be done and it can be done seamlessly and (if you don't need fancy manipulations as per above) it can be done with software that is cheap or free ...
