Abstract: Based on the latest development and technical characteristics of FPD technology, a method for producing seamless tiled FPD panels using optical image-shifting technology was put forward. Two image sections were displayed near the border of FPD panels by means of interlace frame display. The image sections were separated using polarizing rotation apparatus and polarizing beam splitter. The separated image section was moved by imageshifting prism to cover the border. The tiled seam width was reduced from 36 millimeters to three pieces of 0.5 millimeter wide prism seam. The seamless tiling of FPD panels was realized successfully with this technology.
