  • Roll-to-roll method for manufacturing a 2D/3D grating switch membrane
    Patent number: 10466544
    Abstract: A roll-to-roll method for manufacturing 2D/3D grating switch membrane is performed in such a way that: Step 1 and Step 2 are simultaneously performed, then Step 3 is performed, and finally Step 4 is performed: Step 1, subjecting a concave grating facing down to rubbing and liquid crystal dropping; Step 2, uniformly coating a PI liquid onto a surface layer of a mirror-face metal roller, and performing self-hating and rubbing; Step 3, making the concave grating rubbed and dropped with liquid crystals in Step 1 and PI layer coated and directionally-rubbed on the mirror-face metal roller in Step 2 attached to each other, forming a grating membrane, and rotating and pre-baking the grating membrane with the mirror-face metal roller; Step 4, curing the attached and baked grating membrane by the UV curing means and after stripping, collecting and winding through the 2D/3D grating switch membrane collecting roller.
