Geometrically and optically corrected parallax barrier providing autostereoscopic viewing of a display

摘要

A apparatus and method of enabling autostereoscopic viewing of displays with a parallax barrier apparatus is provided. In one embodiment, the present invention employs a parallax barrier, comprising a plurality of opaque barrier lines, disposed on a flexible substrate that can adhere to an existing display. One application of the present invention is in enabling autostereoscopic viewing of a display that is not otherwise configured to display 3D images.

主权项

1. A parallax barrier for autostereoscopic viewing of a display with a plurality of columns of pixels, the parallax barrier comprising:
a substrate comprising a transparent material; a plurality of parallel barrier lines disposed on the substrate, wherein:
each parallel barrier line of the plurality of parallel barrier lines has a width and a height configured to, when the parallax barrier is coupled to the display, obstruct viewing of at least one column of pixels by one eye of a viewer of the display when the viewer is located at one of a plurality of viewing areas;the parallax barrier includes corrective adjustments such that, for each parallel barrier line of the plurality of parallel barrier lines, the width the parallel barrier line varies, the width being wider at the center of the parallel barrier than at either end of the parallel barrier; andthe total number of parallel barrier lines of the parallax barrier is configured to exceed half of the total number of columns of pixels of the display; and an adhesive layer enabling the removal and reapplication of the parallax barrier to a surface of the display.
