OPTICAL PARTS FOR IMAGE DISPLAY

摘要

PURPOSE:To stereoscopically see all over a sheet and to widen the visual stereoscopic sight by letting the optical locus of the central axis of each lens which constitutes a lenticular sheet go through the middle of both eyes. CONSTITUTION:The optical loci (broken lines) of the central axis of each convex lens 11 which constitutes the lenticular sheet are different each other and every optical locus of the central axis is let go through the midpoint 9 of the both eyes 4-a and 4-b. As a result, even with a lens 11 which is outer than the both eyes a user can see stereoscopically. For instance, the display contents of a display element 6-1b for a left eye and that of a display element 6-1a for a right eye which are positioned ends enter into the left eye 4-b as a left eye beam 10b and the right eye 4-a as a right eye beam 10a, respectively and a user can see stereoscopically, so that an image region which can be seen stereoscopically can be widened.
