Automotive polarizer screen shade |
摘要 |
An automotive polarizer screen shade with two parallel plane polarizers, one rectangular and one circular in shape, is invented. The large rectangular semi-transparent polarizer allows the driver to see most of the road clearly while the smaller circular polarizer slides and/or rotates independently to screen the direct sunlight so that the light intensity is tolerable.
