LCD Panel - Can I use it with OHP?

[Mary Degallo]

Hi there!

I cannot afford a LCD projector and am looking for something like this.
If this something that has already been asked, pls excuse me.

I am planning to place a LCD screen on top of a OHP.
The following used SHARP QA 2500. http://www.gideontech.com/guides/projector/

Can I use any LCD panel that is currently available?
I dont know if LCD panels are transparent or have back frame which make them
opaque on one side (like reflection mirrors).

If use an LCD on a OHP, will it get damaged due to heat?
Does an LCD need any software or is just like a mouse - plug and see??
Does any LCD go with any Windows based LAPTOP/desktop?

I appreciate any response in these regards.

-Mary

No, you cannot take any LCD and do this, there are lots and lots of
issues.
In theory it's possible to convert most LCD panels to do this, but
you'd need a detailed knowledge of electronics and optical design.

If you can find one that is designed to do this, then you can
generally just plug it into a monitor connector, and use it.
Otherwise, no.
