Autostereoscropic liquid crystal display apparatus

Abstract

A display apparatus includes an autosteroscopic liquid crystal display panel having a frame response time of less than 10 milliseconds, and a backlight positioned to provide light to the autosteroscopic liquid crystal display. The backlight includes a right eye solid state light source and a left eye solid state light source capable of being modulated between the right eye solid state light source and a left eye solid state light source at a rate of at least 90 Hertz.

What is claimed is: 
     
         1 . A display apparatus, comprising:
 an autosteroscopic liquid crystal display panel having a frame response time of less than 10 milliseconds; and   a backlight positioned to provide light to the autosteroscopic liquid crystal display panel, the backlight comprising a right eye solid state light source and a left eye solid state light source capable of being modulated between the right eye solid state light source and a left eye solid state light source at a rate of at least 90 Hertz.   
     
     
         2 . A display apparatus according to  claim 1 , further comprising a double sided prism film disposed between the autosteroscopic liquid crystal display panel and the backlight. 
     
     
         3 . A display apparatus according to  claim 1 , wherein the autosteroscopic liquid crystal display panel has a frame response time of less than 5 milliseconds. 
     
     
         4 . A display apparatus according to  claim 1 , wherein the backlight comprises a first light input end and an opposing second light input end and the right eye solid state light source is positioned to direct light into the first light input end and the left eye solid state light source is positioned to direct light into the second light input end. 
     
     
         5 . A display apparatus according to  claim 4 , further comprising a synchronization driving element that synchronizes activation and deactivation of the right eye solid state light source and the left eye solid state light source with image frames provided at a rate of 90 frames per second or greater to the autosteroscopic liquid crystal display panel to produce a flicker-free video or rendered computer graphics. 
     
     
         6 . A display apparatus according to  claim 5 , further comprising a video source capable of providing left eye and right eye video frames at a rate of 90 frames per second or greater to the autosteroscopic liquid crystal display panel. 
     
     
         7 . A display apparatus according to  claim 5 , further comprising a rendered computer graphics source capable of providing left eye and right eye video frames at a rate of 90 frames per second or greater to the autosteroscopic liquid crystal display panel.
