A weird and quirky idea - CRT shaped glass/acrylic slab for LCD screens.

Finally, someone posts something as crazy as my "bend it with your mind" idea. (Ok, so you're idea actually has merit. Damn.) Slick! Someone is thinking outside of the box!

There is no spoon box


Unstupid:

I think it would be easier to bend and lcd panel to the rounded dome shape...   ;D

I mentioned this elsewhere but I guess I wasn't elaborate enough.

Start with a CRT -- preferrably a dead one.

Cut a piece of 1/4" acrylic slightly larger than the LCD.

Put the CRT face up in your powder coat oven with the acrylic on top.

Bake at 290(?) degrees until gravity bends the acrylic into a curve.

Allow it to cool.

Add side supports to the acrylic and use it as a mold.

This is the closest. I found a Mac forum (URL escapes me ATM) where old Apples are rebuilt with flat panels. To get the curved look, the dead CRT is removed and used for the Acrylic as either a "pull down" mold or in a vacuum mold.

Bubbling is often a problem but done correctly, you get a shaped piece of acrylic that fits the old shell exactly and gives a nice "pop" to the flat screen. The drawback of a "hollow" space between acrylic and monitor is obvious but unless you make an effort to look for it probably isn't that big of a deal. Overall, based on the build photos at the Apple forum, the results are very pleasing.

I thought of using a lens on a small flat before. Stole an interesting lens about 4" square from my brother in law. After teaching my five year old how to set random things on fire with it (all in the name of SCIENCE!!) I thought to show him what happens if I put the lens over his DSi screen. I was thinking of those old red digit calculators from yonkers ago.  The magnification was ridiculous and I think the line of focus is very narrowly defined for that kind of lens. I'm not an expert but given a monitor of X by Y you're almost guaranteed to find yourself grinding your own lens or find someone to do it for you. I honestly can see it happening but not cheaply or easily. Not as easily as the acrylic method.

jimmer:

just wondering, when you've manufactured this lens and fixed it to your LCD panel, are you going to mount it all behind a flat sheet of plexi?
