Title:
3-DIMENSIONAL GLASSES USING AN ELECTRICALLY REACTING POLARIZING FILM
Document Type and Number:
WIPO Patent Application WO/2013/039302
Kind Code:
A3
Abstract:
Disclosed are 3-dimensional (3D) glasses using an electrically reacting polarizing film. The polarizing film according to the present invention is coated on each lens of a pair of glasses and has an initial light transmittance. Also, when a voltage from a power supply is applied to the polarizing film, the polarized arrangement of the polarizing film may be varied to reduce light transmittance and realize a 3D image. Thus, the electrically reacting polarizing film may be attached to a normal pair of glasses so that the normal glasses can be used as 3D glasses. In some cases, the normal glasses on which the electrically reacting polarizing film is attached may be used as sunglasses. Also, since the voltage from the power source is applied through a detachable power switch which is easily portable, a user does not need to separately carry a normal pair of glasses, a pair of sunglasses, and a pair of 3D glasses. Also, when the wearer of glasses views a 3D image, since it is unnecessary to wear two pairs of glasses, the user may view the 3D image in comfort.
