10. A system of aligning a patterned retarder and a display panel of a three dimensional image display apparatus, the system comprising:
-
a first alignment stage that supports the patterned retarder including first and second patterns having different optical axes and calibrates a position of the patterned retarder; a first vision system that obtains images of the first and second patterns of the patterned retarder; a second alignment stage that supports the display panel and calibrates a position of the display panel; a second vision system that obtains images of alignment marks provided at edge portions of the display panel; and a drum that receives the patterned retarder from the first alignment stage and attaches the patterned retarder onto the display panel on the second alignment stage, wherein the first vision system comprises; a camera; a ½
wavelength plate arranged in front of a lens of the camera;a rotatable ¼
wavelength plate arranged in front of the ½
wavelength plate. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
