Patent number: 9628782Abstract: A method of operating an autostereoscopic display, the autostereoscopic display device comprising a switchable aperture array and a screen, the method comprising: displaying a portion of an image on the screen for a first period of time; and using the switchable aperture array to restrict to a second period of time the time for which a portion of the image is wholly or partly visible; wherein the second period of time is less than the first period of time in order to increase the bandwidth of the autostereoscopic display.Type: GrantFiled: May 30, 2014Date of Patent: April 18, 2017Assignee: SETRED ASInventors: Christian Moller, Doug Patterson, Thomas Ericson

Patent number: 9618762Abstract: A three dimensional display apparatus comprising: a backlight to emit light from switchable apertures, the light being polarized; at least one light modulation panel with pixels that can be set to change the polarization of light; a polarizer that transmits light within a limited range of polarizations; where each light modulation panel can change the polarization such that the light passing through the polarizer can both increase and decrease irrespective of the polarization of light before passing the panel; and where the switching of the apertures are synchronized with the switching of the pixels on the at least one light modulation panel.Type: GrantFiled: May 17, 2012Date of Patent: April 11, 2017Assignee: SETRED ASInventors: Lars Thomas Kristian Ericson, Christian Nicolai Moller

Patent number: 8179424Abstract: A method and apparatus directed to the field of autostereoscopic displays. The method provided is for creating images or image data suitable for use with an autostereoscopic display. The method comprises a projection step and a transformation step for processing item coordinates representing at least one item in a 3D scene to provide images or image data. The transformation step comprises calculating a transformation dependent on the geometry of an autostereoscopic display. The projection step comprises calculating a projection dependent upon a projection plane constructed in the 3D scene. The apparatus comprises an array of apertures and an imaging portion, the imaging portion comprising a plurality of Digital Micromirror Devices.Type: GrantFiled: April 29, 2005Date of Patent: May 15, 2012Assignee: Setred ASInventor: Christian Nicolai Moller
