    • A convertible 2D/3D autostereoscopic display includes of an electronically controllable display screen for displaying two dimensional images thereon and a permanently mounted first lens sheet for projecting 3D autostereoscopic images in a region of space in front of the display. Another lens sheet is pivotally attached to the display to allow it to be swung into and out of physical optical engagement with the first lens sheet. The lens sheets each have complimentary physical structure and optical properties such that when the lens sheets are engaged, the combined lens sheets have a substantially negligible effect on the two dimensional screen image; while disengagement of the lens sheets resumes the display to the 3D autostereoscopic display mode. Complimentary alignment structure is also provided in corresponding non-lens regions of the lens sheets for aligning the respective lenslets when the sheets are engaged. Conventional latches are also provided to secure the lens sheets when they are engaged. In another embodiment, a lens sheet is selectively engageable with a 2D display to form 3D autostereoscopic images when in a closed position and allow 2D viewing when in an open position.
    • 可转换的2D / 3D自动立体显示器包括用于在其上显示二维图像的电子可控显示屏和用于在显示器前面的空间区域中投影3D自动立体图像的永久安装的第一透镜片。 另一个透镜片被可枢转地附接到显示器上,以允许其与第一透镜片物理光学接合摆放进去。 透镜片各自具有互补的物理结构和光学性质,使得当透镜片接合时,组合的透镜片对二维屏幕图像具有基本上可忽略的影响; 而透镜片的分离将使显示器恢复到3D自动立体显示模式。 在透镜片的相应非透镜区域中还提供免费对准结构,用于当片材接合时对准各个小透镜。 还提供传统的闩锁以在接合时固定透镜片。 在另一个实施例中,当处于关闭位置时,透镜片可选择性地与2D显示器接合以形成3D自动立体图像,并且当处于打开位置时允许2D观看。
