GLASSES-FREE 3D DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/026128
Kind Code:
A1
Abstract:
A glasses-free 3D display device that provides a wide viewing angle and can stably produce sharp images, whereby moiré patterns do not appear on the display surface and the images themselves do not degrade. Said glasses-free 3D display device (10) comprises: a display device (1) that displays images on a display surface (2); and a lenticular sheet (31) that has a lenticular lens array (32). Attaching the lenticular sheet (31) to the display surface (2) such that the direction (E-E) in which the lenticular lens array (32) extends is angled with respect to the vertical direction (Y) or horizontal direction (X) of the display surface (2) makes it possible to capture multi-view images from one-view images, i.e. normal video, using the aforementioned single lenticular sheet.
