I am about to acquire an old LCD panel from my company (nice and cheap and VGA 640x480 with an integrated controller). This is one of those panels that was used about 8-9 years ago, sitting on an overhead projector to display Powerpoint presentations. What I am looking for is any thoughts/ideas on a custom backlight. My plan is to mount this between my visors in the roof of my Dodge Ram pickup. Ideally, I would like to find an old head unit lighting circuit, so that it would be on full during the day, and adjustable with my dash light dimmer when my headlights are on.
