METHOD FOR PREPARING POLARIZATION GRATING SCREEN, POLARIZATION GRATING SCREEN AND 3D DISPLAY DEVICE COMPRISING THE SAME

摘要

PURPOSE: A 3D image display comprised of the manufacturing method of the polarizing grating screen, and the polarizing grating screen and this. The adhesion between the material and the mask are considered. The uniformity of the patterning spacing is enhanced. CONSTITUTION: The polarizing grating screen(100) is composed of vertical patterns(111, 112). The vertical pattern adsorbs iodine in the polyvinyl alcohol film. Repetitively, it aligns. The other vertical pattern colors pattern and the iodine absorbed and originated between pattern. Repetitively, it is formed.
