LCD hacking idea

[Rachie5272]

I have a bunch of bare LCD panels from old monitors laying around, and it would be nice to do something useful with them.  Yes, I understand trying to interface them to display images and such is no small task, but what about something simpler?  How about solid colours?

Would it be possible to simply pull the colour data lines high or low, then pulse the clock line?  If so, it would be very easy to control the colour with a microcontroller, making for some neat artistic creations.

Any thoughts?

Maybe LVDS to HDMI or similar driver. im thinking in Flight sims or race sims.

You'll need to figure out what type of interface they use. Older ones with TTL are not that difficult to interface to, the LVDS ones will require a separate driver circuit.

Something like this?

Interesting, but not what I'm thinking of at all.  I mean not displaying anything but a single, solid colour over the entire LCD.  More of a colour changing window than a display.

It seems this would be as simple as permanently setting the colour data lines either high or low, and letting the controller read the colour data for every clock cycle.  If I'm right, this means the electronics can be as simple as three DIP switches and an oscillator.
