Embodiment Construction

[0013] Some examples are described more fully hereinafter with reference to the accompanying drawings that illustrate example embodiments. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. These aspects may, however, be embodied in many different forms and should not be construed as limitations to the embodiments presented herein.

[0014] Referring to FIG. 1 , a top view of certain components in a conventional autostereoscopic display device 100 is schematically shown. The conventional autostereoscopic display device 100 may include a screen (not shown), such as a glass cover, a pixel image source 102 arranged along a pixel plane 104, including a row of columns represented by arrows along an optical plane 108. lens element 106 of lens 122 , and processor 109 configured to condition the content of pixel image source 102 . The viewer's first eye 110 and second eye 112 are located on a viewing screen 114 , wh...

Abstract

An autostereoscopic display device includes a pixelated image source, a lenticular element and an optical splitting element. The pixelated image source includes a matrix of pixels and dark regions. The lenticular element includes a plurality of cylindrical lenses and is disposed adjacent the pixelated image source such that each of the cylindrical lenses extends over a substantially equal area of dark regions. The optical splitting element is configured such that a first eye sees first sub-pixels located along first parallel lines behind each of the cylindrical lenses with respect to the observer and a second eye sees second sub-pixels located along second parallel lines behind each of the cylindrical lenses. The first parallel lines and the second parallel lines are parallel with the cylindrical lenses. The first parallel lines extend over three neighboring sub-pixels within each of the rows. The second parallel lines extend over three neighboring sub-pixels within each of the rows.

Description

[0001] This application claims priority to US Patent Application No. 13 / 662635, filed October 29, 2012, the contents of which are hereby incorporated by reference in their entirety. technical field [0002] The present invention relates to autostereoscopic display devices, and, more particularly, to apparatus and methods for reducing visual defects present in autostereoscopic display devices. Background technique [0003] Autostereoscopic display devices can produce a three-dimensional (3D) effect when the viewer is not wearing special headgear or glasses. Although there are many methods for implementing autostereoscopic display devices, these methods usually cause visual defects that can be felt by the viewer, and make it difficult for the viewer to clearly see the image from different viewing angles or positions over a long period of time, etc. See 3D images with satisfactory quality. Therefore, it is necessary to improve the defects existing in the existing autostereosco...
