Publication number: 20120249968Abstract: A light beam projected from a projector passes through a microlens and then is focused on an extremely small region (hereinafter, will be called a deflection point). After that, the light beam is diverged as a directional light beam from the region serving as the deflection point. Thus, a viewer of a stereoscopic display perceives light beams as extremely small pixels. In reality, the deflection points are largely spaced, so that a rough image is perceived by a viewer who observes a screen. An autostereoscopic display including a two-dimensional image display device and an optical element, the optical element having a structure that simultaneously diffuses and deflects light emitted from the two-dimensional image display device, so that a stereoscopic image is displayed.Type: ApplicationFiled: November 9, 2011Publication date: October 4, 2012Applicant: HITACHI CONSUMER ELECTRONICS CO., LTD.Inventors: Takafumi Koike, Michio Oikawa, Masami Yamasaki
