Abstract
A method of removing a Moire pattern in a 3D image display apparatus using complete parallax. The method of removing a Moire pattern in a 3D image displaying system with an image display device having an image display panel and a unit for providing complete parallax, by intersecting the image display panel and the unit with each other at a predetermined angle. The unit is an intersection lenticular plate or a micro lens array plate located at a front or rear of the image display panel.
Claims8
A method of adjusting a Moire pattern that appears when a first plate having a first pattern with a first period overlaps a second plate having a second pattern with a second period, the method comprising:
- orienting the first and second plates with respect to each other such that the first pattern forms an angle with the second pattern, and a period of the Moire pattern is smaller than a period that can be detected by a viewer;
- and
- setting the angle between 20 and 30 degrees such that a variation of a spatial frequency of the Moire pattern as a function of a viewing distance is minimized.
A method of modifying a Moire pattern in a 3D image displaying system with an image display device having an image display panel and a unit for providing complete parallax, the method comprising:
- orienting the image display panel and the unit with respect to each other such that a first pattern of the image display panel forms an angle with a second pattern of the unit, and a period of the Moire pattern is smaller than a period that can be detected by a viewer;
- and
- setting the angle between 20 and 30 degrees such that a variation of a spatial frequency of the Moire pattern as a function of a viewing distance is minimized.
