Patent ID: 8848119

Claim:
A polarization control device supplied with a first outgoing light of a right-eye image and a second outgoing light of a left-eye image, which are outgoing lights of parallax images for stereoscopic view from an external device in a time-divisional manner with a predetermined period, and adapted to convert polarization directions of the first outgoing light and the second outgoing light so as to be different from each other, and then emit the first outgoing light and the second outgoing light, the polarization control device comprising: a first polarizing liquid crystal panel adapted to convert polarization of the first outgoing light and the second outgoing light into a second polarization having a polarization direction different by 90° from a first polarization, and emit the first outgoing light and the second outgoing light during a specified time of time from a time point when the external device performs a process of switching from either one of the first outgoing light and the second outgoing light to the other in sync with the process of switching by the external device; a polarization plate having a transmission axis having a polarization direction coinciding with the first polarization; and a second polarizing liquid crystal panel adapted to convert the first polarization of each of the first outgoing light and the second outgoing light input through the polarization plate into third polarization and fourth polarization having respective polarization directions different from each other, and then emit the result in every predetermined period.
