Video Screen Windshield Wiper

 Five rows of LED arrays parallel to the windshield wiper create a video screen display through the windshield.

This may work best with [Bungston's] rotary windshield wiper but would also work with a fast back and forth movement. The TV signal is converted with a known formula to drive rotating LED array radii.

Either rear or elevated video camera view or front facing infra-red cameras can superimpose their images on the windshield. With adjustable bright LEDs, the driver's visibility of the road in adverse conditions is improved..
