Autostereoscopic display with illuminating lines, light valve and mask

摘要

A flat screen autostereoscopic display for bright wide angle stereoscopic images employs a flat screen on which are displayed a plurality of regularly spaced discrete, finite light emitting sites such as thin, vertical light emitting lines. A light valve located in front of the screen forms images by means of varying the transparency of individual pixels arranged in a raster pattern across its surface. A mask in front of the light valve completes the display unit to enhance the parallax effect obtained by the viewer. The screen and light valve are arranged in such a way that an observer sees the light emitting lines through one set of pixels with the left eye and the same lines through a different set of pixels with the right eye. The autostereoscopic effect is obtained when the viewer sees with the right eye and the left eye either alternating rows or alternating columns of pixels.
