Polarized sunglasses are designed to block horizontally polarized light rays so as to block light reflected from the (horizontal) pavement in front of the car.
My 16/9 navigation screen seems to output light polarized on this same plane so all information on the screen is filtered out by polarized sunglasses.
Would the screen output vertically polarized light the situation would be ideal, your polarized sunglasses blocking reflections from the pavement ahead of you while fully letting through light from your screen.
Can the screen be somehow modified or changed to output vertically polarized light?
Thanks.
