Abstract
An improved 2D/3D display is disclosed. In one embodiment, the display uses both an imaging LCD and a secondary LCD. The secondary LCD is a light line forming LCD which can be placed between a light line forming system and the imaging LCD for eliminating ghost images, or can be used as the light line forming system itself. Variations of a glass sandwich employing an imaging liquid crystal layer and a line forming liquid crystal layer are disclosed. Alternatively, the secondary LCD may comprise a liquid crystal layer and a series of polarizing strips. Displays in which a 2D or 3D window can be viewed within a 3D or 2D window, respectively, are disclosed using light line forming systems and alternatively using light line forming LCD's which have the opaque stripes divided into individually controllable areas. Movement of one window within another window is disclosed. Also disclosed is a strip diffuser for improving visual characteristics in 3D mode and movable elements for alternating between 2D and 3D mode.
