Idea for laptop LCD repurposed as a photoblocking license plate cover

OK, here is an idea so horrible I had to share it, since I've been on the photoblocking topic lately.

Another possible anti-speed camera technology is to repurpose an old laptop as an LCD chopper.   The idea is that the backlight and cover of the laptop screen will be removed so that the screen becomes a see through license plate cover.   The laptop will be programmed to display a series of black stripes across the screen that will move so fast as to appear like a gray tinted screen.  To a camera that freezes the motion, some section of the plate will always be covered with a black stripe and be unreadable.

There are all kinds of issues.  In my state license plate covers are illegal, maybe elsewhere they are not.   I do see people with them all the time, so I guess the police haven't pulled over everyone.  The LCD screen would not be the right shape for the plate, although maybe one could be found that is acceptable.   The screen might be pretty dark and earn you a ticket anyway.   The LCD will be fragile and certainly would not hold up to northeast US weather.   But since when has sanity stopped an inventor?

I wouldn't be able to do field trials where I live, but just making note of the idea while I wait for more LEDs to come.  I'll develop this idea more later.
