    • Displaying data private to a first user and data private to a second, collocated user on a single computer display is achieved by providing two pairs of stereoscopic glasses, one for each user, and modifying the glasses by swapping one of the lens from the first pair with one of the lens of the second pair so that the modified first pair of glasses allows viewing of the display in a first state and the modified second pair of glasses allows viewing of the display in a second state. The data private to the first user is displayed when the display is in the first state and the data private to the second user is displayed when the display is in the second state. The display is alternately switched between the first and second states many times per second, thereby providing private displays for each user. In one embodiment, the stereoscopic glasses are polarized glasses and the display includes a polarizing filter. In another embodiment, the stereoscopic glasses are shutter glasses. In yet another embodiment, the stereoscopic glasses are colored glasses for viewing a composite image of the data private to each, with specialized colors used to ensure privacy of the display.
    • 在单个计算机显示器上显示对第一用户私有的数据和对第二个并置用户私有的数据是通过提供两对立体眼镜来实现的,每对立体眼镜每个用户一个,并且通过从第一对交换一个透镜来修改眼镜 其中第二对的透镜中的一个使得经修改的第一对眼镜允许以第一状态观看显示器,并且经修改的第二对眼镜允许在第二状态下观看显示器。 当显示处于第一状态时显示第一用户私有的数据,并且当显示处于第二状态时,显示第二用户的私有数据。 显示器每秒多次在第一状态和第二状态之间交替切换,从而为每个用户提供私人显示。 在一个实施例中,立体眼镜是偏振眼镜,并且显示器包括偏振滤光器。 在另一个实施例中,立体眼镜是快门眼镜。 在另一个实施例中,立体眼镜是彩色眼镜,用于以专用的颜色来观看数据的合成图像,所述专用颜色用于确保显示器的隐私。

    • There is disclosed an optical beam deflection arrangement which may be used in an autostereoscopic display device. The arrangement comprises a substrate; a first layer, for example formed of an optically isotropic solid and having a curved surface facing towards the substrate; and a second layer, for example formed of a liquid crystal material confined between the substrate andthe first layer. An interface between the first and second layers may, for example, define an array of parallel lenticulars. A refractive index of the second layer, for light of a predetermined polarization, maybe switchable between a first value matching the refractive index of the first layer and a second value different to the refractive index of the first layer, to thereby selectably provide a beam deflectionfunction. The substrate is spaced from the first layer by a plurality of spacers which are extended from the substrate or from the first layer, the spacers making point or line contact with the other one of the substrate and the first layer. The spacers may comprise elongate spacers having a length direction parallel to the plane of the substrate.The substrate and the first layer may be formed offlexible plastics materials, in which case the arrangement may be manufactured using roll- to-roll processing techniques.
    • 公开了可用于自动立体显示设备中的光束偏转装置。 该装置包括衬底; 第一层,例如由光学各向同性固体形成并具有面向衬底的弯曲表面; 和第二层,例如由限制在基底和第一层之间的液晶材料形成。 例如,第一和第二层之间的界面可以限定平行透镜阵列。 对于预定偏振的光,第二层的折射率可以在与第一层的折射率匹配的第一值和不同于第一层的折射率的第二值之间切换,从而可选择地提供光束偏转函数 。 衬底通过从衬底或从第一层延伸的多个间隔物与第一层间隔开,间隔物使得点或线与衬底和第一层中的另一个接触。 间隔物可以包括具有平行于基底平面的长度方向的细长间隔物。基底和第一层可以形成不可弯曲的塑料材料,在这种情况下,该结构可以使用卷对卷处理技术来制造。
