Abstract
Abstract A full color liquid crystal flat panel display having a step waveplate providing one-quarter and three-quarter wave phase retardation to alternating rows which provide left and right views. The result of right and left are circular polarized in opposite directions which two a viewer wearing circularly polarized glasses provides the left and right views to the appropriate eye such that the viewer is able to see full color three-dimensional images.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
125 words
A full color, three-dimensional flat panel display comprising: means for displaying a first image having a first polarization; means for displaying a second image having a first polarization; means for changing the first polarization of the first image to a second polarization; and means for changing the first polarization of the second image to a third polarization; and wherein: the first polarization is linear; the second polarization is circular having a first direction; the third polarization is circular having a second direction; said means for displaying a first image ia first plurality of display lines; said means for displaying a second image is a second plurality of display lines; and said first plurality of display lines is interlaced with said second plurality of display lines.
Claim 2
Dependent Claim
125 words
A full color, three-dimensional flat panel display comprising: means for displaying a first image having a first polarization; means for displaying a second image having a first polarization; means for changing the first polarization of the first image to a second polarization; and means for changing the first polarization of the second image to a third polarization; and wherein: the first polarization is linear; the second polarization is circular having a first direction; the third polarization is circular having a second direction; said means for displaying a first image ia first plurality of display lines; said means for displaying a second image is a second plurality of display lines; and said first plurality of display lines is interlaced with said second plurality of display lines.
Claim 3
Dependent Claim
26 words
Apparatus of claim 1 wherein each of said first plurality of display lines alternates with each of said second plurality of display lines, on said display.
Claim 4
Dependent Claim
70 words
Apparatus of claim 2 wherein said means for changing the first polarization of the first image to a second polarization and said means for changing the first polarization of the second image to a third polarization are a wave retarder proximate to said display, having a structure that applies one-quarter-wave retardation and three-quarter-wave retardation to said first plurality of display lines and to said second plurality of display lines, respectively.
Claim 5
Dependent Claim
38 words
Apparatus of claim 3 wherein said wave retarder is a waveplate having one-quarter wave and three-quarter wave steps etched in said waveplate in the form of lines that overlap the first and second pluralities of display lines, respectively.
Claim 6
Dependent Claim
80 words
Apparatus of claim 2 wherein said means for changing the first polarization of the first image to a second polarization and said means for changing the first polarization of the second image to a third polarization are a wave retarder proximate to said display, having a structure that imparts a clockwise rotation to the first polarization and a counterclockwise rotation to the second polarization of said first plurality of display lines and of said second plurality of display lines, respectively.
Claim 7
Dependent Claim
15 words
Apparatus of claim 5 wherein said wave retarder is a ferro-electric liquid crystal faraday rotator.
Claim 8
Dependent Claim
44 words
Apparatus of claim 2 wherein said flat panel display provides three-dimensional images to a viewer at a given level of resolution and provides two-dimensional images to the viewer at twice the given level of resolution, when the first and second images are the same.
Claim 9
Dependent Claim
118 words
A full color, three-dimensional flat panel display comprising: a first plurality of display lines for emitting light of a first image, having a first polarization; a second plurality of display lines for emitting light of a second image, having a first polarization; and an optical retarder, fixed on said display, for converting the light of the first image to a second polarization and the light of the second image to a thrid polarization, having areas of a fist thickness situated proximate to the first plurality of display lines and having areas of a second thickness situated proximate to the second plurality of display lines; and wherein he first an second images are capable of providing a three-dimensional image.
Claim 10
Dependent Claim
118 words
A full color, three-dimensional flat panel display comprising: a first plurality of display lines for emitting light of a first image, having a first polarization; a second plurality of display lines for emitting light of a second image, having a first polarization; and an optical retarder, fixed on said display, for converting the light of the first image to a second polarization and the light of the second image to a thrid polarization, having areas of a fist thickness situated proximate to the first plurality of display lines and having areas of a second thickness situated proximate to the second plurality of display lines; and wherein he first an second images are capable of providing a three-dimensional image.
