Strip?

Hi, I was planning on making something like a touch screen table sort of thing for my living room, I thought it would be cool :D, but there is one thing holding me back, they have to be so big! Is there any way I could use the strip that they use in LCD monitors instead of a huge projector? The Projector seems to connect via USB, is that possible with the LCD strip? If not a VGA>USB adapter should work.

Thanks a lot for the help,

I'm just trying to understand what you mean by strip? This would be interesting.. If I could have a touch screen table with Ms. Pac Man.. That would be the "...."
 
Sorry, haven't been on in a while, it looks like this |||||||| on the top? It's what projects the picture on the screen for lack of better words.
 
Can you be a bit more clear, I did not get what you want to do?
I get you need to make a touch screen table but how are you planning to do that and where does a projector come in?

If you are interested in some making something your own then I might have a very comprehensive and difficult solution for you but it will get you exactly what you need, kinda like Ironman's Computer desk but it will also involve writing your own software
 
Sorry, I told you I'm at a loss of words as to what I'm talking about, lemme put it simply, while a CRT uses a projector to display the picture, an LCD uses _____

An LCD uses pixels... Each pixel lights up a different color based on what you are viewing.
 
I understand that it's based on pixels, but how does it send the picture from the VGA/DVI/HDMI cable to the screen, that strip that I'm talking about.

There isn't an actual "strip" in the terms that I think you mean, there is a controller in the monitor that basically tells the pixels what color to turn based on the signal it is being received from the input device.

Ah okay, now I understand, so there isn't any way to have a connector from that controller to USB then?
 
LCDs work using liquid crystals. The screen is divided into a grid, each pixel being a layer of liquid crystals between two conductive layers that allow a charge to be sent through the crystals. Liquid crystals work because they align themselves in different ways depending on the electrical current passed through them, since they are crystals these different alignments let you bend light in certain ways, i.e. changing the color of light that passes through them.

That means that the only thing that is actually projected through the entire screen from the edge plain white light. The rest of the "strip" is sending different currents through the screen to make the crystals in the pixels represent the right colors. The actual crystals don't emit any light, only change the light that passes through them.

Basically what I'm trying to get at is glass screen is actually the component that creates the image, so there is no such thing an LCD strip that you can attach to a plain piece of glass or whatever it was that you were thinking.
