The problem is, LCDs don't display their image well by just reflection. That's why if your backlight goes out, the image will still be incredibly dark with bright light shining on it, because it has to shine THROUGH it for the image to really display.

Basically, that, combined with the fact that the light wouldn't all go to the lens, and the fact that it's just using 2 regular light bulbs, would probably make a pretty darn dark image. But feel free to try it, as obviously it can't ruin your LCD like opening it up could. 🙂

P.S., if you like this idea because you're scared of breaking an LCD while disassembling it, don't be. As long as you ground yourself while you're working on it (I just hooked up a copper wire from my plumbing to my wrist), and don't rip any of the FCC cables, you can't really do much damage.

Just my two cents
 
that plan is for an old stereoscopic postcard projector. the light in the box makes the postcard obviously visible to the naked eye so, therefore the lens is able to "see the image" and project it. the same lights may wash out the lcd image. throw in a glare factor and you'd probably get better results not using extra lights at all. the whole "build a cardboard box around your 13 inch tv and turn it upside down" is based on this very obsolete technique. go to ebay and type in "antique projector" or postcard projector" and you can see, you can buy one of these old bessy's for about ten bucks. it couldn't hurt to try as long as you don't use those bulbs. the heat could damage your screen. at a MAXIMUM lcd's are only supposed to get up to 105-110 degrees F. they're not built to run at that temp constantly. i seriously doubt you'll come up with any satisfactory results, but let us know.
 
Built it today

I built the projector today but found the results were poor (after 3 hours work !)
I wouldn't reccomend this plan,
however i have just got a ps1/x 5" LCD of of ebay and am looking forward to building a PJ using it 😀
