Abstract
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.
