COLOR SELECTIVE ACTIVE POLARIZER AND MAGNETIC DISPLAY PANEL EMPLOYING THE SAME

摘要

Provided are a color selective active polarizer controlled by a magnetic field and a magnetic display panel employing the color selective active polarizer. The color selective active polarizer includes a magnetic material layer structured such that magnetic particles are buried in a transparent insulating medium. Dyes or color absorbing particles are mixed in the magnetic material layer. The color selective active polarizer transmits light polarized in a first direction and reflects light polarized in a second direction when a magnetic field is applied. The light polarized in the first direction transmitted by the color selective active polarizer has colors according to the dyes or color absorbing particles.
