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

摘要

PURPOSE: A manufacturing method, a screen thereof, and a 3D image display device thereof are provided to improve the adhesive property between a mask and a polarized light device when the polarized light device is decolorized by using a formed pattern as a mask. CONSTITUTION: A polarizing grating screen(100) is composed of vertical patterns(111,112). The vertical pattern absorbs the iodine and aligns it. A different vertical pattern is formed by decolorizing the absorbed iodine. The vertical pattern shields the light of a back light. Different vertical pattern passes through light.
