Abstract
A display system for stereoscopic displaying of images includes a pair of wide viewing angle displays arranged at an angle to each other, each display providing respective images formed by plane polarized light. A beam combiner is located between the displays such that the beam combiner transmits light from one display and reflects light from the other display, whereby the transmitted and reflected light are provided via the beam combiner in substantially the same direction. One of the wide viewing angle displays has a substantially vertical polarization and the other of the wide viewing angle displays has a substantially horizontal polarization. The display system provides for stereoscopic display of high-resolution images with wide horizontal and vertical viewing angles.
Claims81
A display system, comprising:
- a pair of wide viewing angle displays arranged at an angle to each other, each display providing respective images formed by plane polarized light;
- a beam combiner located between the displays such that the beam combiner transmits light from one display and reflects light from the other display, whereby the transmitted and reflected light are provided via the beam combiner in substantially the same direction;
- and
- wherein one of the wide viewing angle displays has a substantially vertical polarization and the other of the wide viewing angle displays has a substantially horizontal polarization.
A display system comprising:
- a pair of active matrix liquid crystal displays (AMLCDs) arranged at an angle to each other, the AMLCDs having the same relative orientation and producing images having orthogonal polarization;
- and
- a beam combiner disposed between the AMLCDs such that the beam combiner transmits light from one AMLCD and reflects light from the other AMLCD.
A method of displaying stereo images, comprising
- simultaneously displaying a left eye image on a first wide viewing angle display and a right eye image on a second wide viewing angle display such that the left eye and right eye images have optical polarization in orthogonal directions;
- using a beam combiner so positioned relative to the two wide viewing angle displays that one can be viewed directly through the beam combiner and the other can be viewed by reflected light from the beam combiner;
- and
- combining the left eye and right eye images in a common light path such that the optical polarization of the left eye image portion and the right eye image portion are different in such common light path such that the image portions can be separated based on optical polarization.
A method of providing a high-resolution wide viewing angle stereoscopic display system that includes a pair of high-resolution wide viewing angle displays, each of the high-resolution wide viewing angle displays having a relatively vertically oriented plane polarizer and a relatively horizontally oriented rear polarizer, one of the polarizers being at the front and the other of the polarizers being at the rear of the respective high-resolution wide viewing angle displays, the method comprising:
- re-orienting the front and rear polarizers on one of the high-resolution wide viewing angle displays by 90 degrees;
- and
- arranging the high-resolution wide viewing angle displays at an angle relative to one another, and positioning a beam combiner between the high-resolution wide viewing angle displays such that the beam combiner transmits light from one of the high-resolution wide viewing angle displays and reflects light from the other high-resolution wide viewing angle display in substantially the same direction such that light from the respective displays is orthogonally polarized.
A method of making a display system comprising:
- selecting a first liquid crystal display (LCD) having a pair of plane polarizers and optical material between the polarizers selectively operable to change the polarization direction of light;
- selecting a second LCD that is substantially the same as the first LCD;
- and
- repositioning the polarizers of the second LCD relative to the optical material thereof to be substantially orthogonal to the corresponding polarizers of the first LCD.
A method of preparing a liquid crystal display that has a liquid crystal cell and a pair of plane polarizers attached to opposite sides of the liquid crystal cell, the method comprising:
- removing the pair of plane polarizers from the liquid crystal cell and re-attaching the pair of plane polarizers to the opposite sides of the liquid crystal cell at 90 degrees relative to their original orientation.
A display system comprising:
- a pair of liquid crystal cells, the liquid crystal cells having liquid crystal alignment characteristics that provide a wide viewing angle;
- a beam combiner that combines images from the pair of liquid crystal cells;
- and
- each of the liquid crystal cells including a pair of plane polarizers, wherein the pair of plane polarizers corresponding to each liquid crystal cell is oriented such that the polarization direction of plane polarized light from one liquid crystal cell is parallel to the plane of the beam combiner and the polarization direction of plane polarized light from the other liquid crystal cell is relatively orthogonal to that of such one liquid crystal cell.
A display system, comprising:
- a pair of wide viewing angle displays arranged at an angle to each other, each display providing respective images formed by plane polarized light;
- a beam combiner located between the displays such that the beam combiner transmits light from one display and reflects light from the other display, whereby the transmitted and reflected light are provided via the beam combiner in substantially the same direction;
- and
- wherein light incident on the beam combiner from one of the wide viewing angle displays has substantially vertical polarization and light incident on the beam combiner from the other of the wide viewing angle displays has substantially horizontal polarization.
