I was planning on the acrylic laying flat for the top surface when poured in the mold but the stuff I used was pretty thick so surface tension would cause the edges to curve up or down against the walls. You could make it wider and cut off the distorted sides or put a glass lid on the mold and fill...

Since the picture didn’t upload I will describe it. Flat on top, concave against the LCD to spread out the image lengthwise. If there is an easy way to upload pictures, please let me know. If you look under the white box you typed you message in, there will be an small black arrow and the words "...

Maybe use lenses like in picture to expand the display and cover up the ends. If you figure out the radius, you could make a mold and cast all of them at once with clear acrylic and cut them into the widths you need.[img] Clyde, This is a very nice idea! I have been looking into the lens idea you s...

Think: plotter, etch-a-sketch, fluorescent text, rotating drum with text, Phil's projector idea, fiber optics and leds, light pipes, mirrors..... don't get painted into a corner with your ideas. Good Dr_When, Plotter: Are you suggesting using a plotter to write out/stamp information in each area? K...

Hi, What pixel density are we talking about here? What are you planning to display, text, graphic or just light effects? Is the 1.5" x 24" the max dimension of the module or the size of the display area? What thickness are we talking about? Why does it need to be LCD? TOK ;) Gorgon, It does not nee...

Liquid crystal displays have to be sealed to avoid degradation of the liquid crystal material. This seal requires space all the way around the display, and this may make it impossible to stack them end-to-end without interruption. A 24" long LCD could probably be made as a custom item, but would pr...

a lot depends on the pix height you want. for a moderately expensive solution, use a small projector to build a rear projection uint. You might have to sacrifice a lot of the vertical lines but it would look pretty good, I bet. depends on how much depth you have. It sure would be bright, though. al...

Start with a larger one, [24 x ?] and divide it into smaller units. Five of six concurrent strips from one large one? Its called multiplexing. Unless over size is the issue? Chris I would like to start with one large 24x ? and divided in into smaller units. The Question is What text technology woul...

Okay, we know the what. If we know more of the why behind the what we can give some useful advise. One and a half by twenty four inches is a bit disproportionate for any application I can imagine.

Sometimes, when you have an idea, you have to think about what you are doing and approach it from a completely different perspective. Yours is one of those. You are wise. And I appreciate your comment and suggestion of searching for a solution from a completely different perspective. But would you ...

I can not find a large thin Graphic LCD, so I thought maybe I could place several small LCD next to each other to make one big Graphic LCD. Problem: Trying ...
