Abstract:
1. A method for fabricating lenticulars, comprising the acts of: applying a rubbing layer on a lenticular foil having lenticular cavities, wherein the lenticular foil is unattached to a plate having a coefficient of thermal expansion different from the lenticular foil; baking the rubbing layer on the lenticular foil in an unconstrained condition before installation of the lenticular foil on the plate; after baking, applying the lenticular foil to the plate; rubbing the rubbing layer; filling the lenticular cavities in the lenticular foil with liquid crystal material; applying a substrate with a second rubbing layer to seal the liquid crystal in the lenticular cavities to form lenticulars; forming electrodes adjacent to the lenticulars for altering an electric field to permit switching of the lenticulars, and providing a display portion to illuminate the switchable lenticulars using pixels and control switching operations of the lenticulars.
