Display unit, position adjusting pattern display program, recording medium, polarization glasses, and filter position adjusting method for display unit
First Claim
1. A display device which comprises an image display section for displaying image information at a first segment and a second segment, and which is used along with a divided wavelength plate filter for rotating polarized light from the image information at the first segment in a direction that is different from the direction of polarized light from the image information at the second segment, wherein the display device displays a position adjustment pattern having colors, figures, characters, symbols, diagrams, or designs or combinations thereof which differ from each other depending upon the segment when the relative positions of the image display section and the divided wavelength plate filter is to be adjusted.

Abstract
Even if a divided wavelength plate filter is mounted, it is possible to reliably display a three-dimensional image or perform a displaying operation on from one screen to a plurality of screens. In a display device, the relative positions of an image display section and a divided wavelength plate filter for rotating polarized light from image information at a first segment in a direction that is different from the direction of polarized light from image information at a second segment can be adjusted. At the time of positional adjustment, the display device displays a position adjustment pattern (112) having colors, figures, characters, symbols, diagrams, or designs, or combinations thereof which differ from each other depending on the segment.

13. A method of adjusting the position of a filter of a display device which comprises an image display section for displaying image information at a first segment and a second segment, wherein a position adjustment pattern having colors, figures, characters, symbols, diagrams, or designs or combinations thereof which differ from each other depending on the segment is displayed on the image display section through a divided wavelength plate filter for rotating polarized light from image information at the first segment of the image display section in a direction that is different from the direction of polarized light from image information at the second segment of the image display section;
- the positional shift between the position adjustment pattern and the divided wavelength plate filter is detected in accordance with the state of the position adjustment pattern through the divided wavelength plate filter; and
the relative positions of the image display section and the divided wavelength plate filter are adjusted in order to reduce the detected positional shift. - View Dependent Claims (14, 15)
