Abstract

La présente invention se rapporte à des lunettes pour voir en trois dimensions (3D) qui utilisent un film de polarisation réagissant électriquement. Le film de polarisation selon la présente invention est appliqué sur chaque verre d'une paire de lunettes et présente un premier facteur de transmission lumineuse. En outre, lorsqu'une tension provenant d'une alimentation électrique est appliquée au film de polarisation, l'agencement polarisé du film de polarisation peut être modifié pour réduire le facteur de transmission lumineuse et réaliser une image en 3D. Ainsi, le film de polarisation réagissant électriquement peut être fixé à une paire de lunettes normales de telle sorte que les lunettes normales puissent être utilisées comme lunettes pour voir en 3D. Dans certains cas, les lunettes normales, sur lesquelles est fixé le film de polarisation réagissant électriquement, peuvent être utilisées comme lunettes de soleil. De même, puisque la tension provenant de l'alimentation électrique est appliquée au moyen d'un commutateur électrique amovible qui est facilement portable, un utilisateur n'a pas besoin de transporter séparément une paire de lunettes normales, une paire de lunettes de soleil, et une paire de lunettes 3D. De même, lorsque la personne qui porte les lunettes voit une image en 3D, puisqu'il n'est pas nécessaire de porter deux paires de lunettes, l'utilisateur peut voir les images en 3D en tout confort.
