A friday question early:
Can you remove the backing of a simple LCD to achieve a transparent display? Like an
alarm clock
If so, is this possible only with these types of simple LCD, or can it be applied further to other things like phone displays? (I assume not tbh -
otherwise I probably would have seen it already)
Sorry for the randomness!

As LCDs depend on light projected from behind to make them visible, you might be able to use ambient light in some situations.
The backing might be difficult to remove with damaging the LCD though.
ibm used to do a laptop (when colour LCD screens were new for computers) where you could remove the back and use it on a overhaed projector, so i guess it can be done, again though, whether you'd damage the LCD though...
man don't do that nearly gave me a heart attack!
ITS FRIDAY!!!!!
Anyway yes LCD's can work either with a reflective backing i.e. mirrored or with the light going straight through like a LCD TV. There are two
polarized films on the glass sheet with the direction of polarisation being the same. The liquid crystal when charged bends the light so it is as
though one of the polarized sheets has been turned 90 degs so no light gets through.

I've seen a transparent LCD alarm clock. It was almost impossible to read unless you held it up to the light. Clever but useless.
