SWITCHABLE LENTICULAR ARRAY FOR AUTOSTEREOSCOPIC VIDEO DISPLAYS

摘要

Lenticles of a lenticular array can be electronically controlled to be optically equivalent to either of two sets of v irtual lenticles having two distinct physical characteristics. Each of the lenticles is in sufficiently close proximity to one or more switchable prisms to optically combine with therewith. The switchable optical elements can be switchable columnar prisms for example. In a first state, the switchable prisms optically combine with the lenticles such that the combination is optically equivalent to a first set of virtual lenticles. In a second, different state, the switchable prisms optically combine with the lenticles such that the combination is optically equivalent to a second, different set of virtual lenticles. Accordingly, the lenticular array can switch between two distinct configurations with the flip of a switch.
