Curved Lenses Configured to Decode Three-Dimensional Content
摘要:
Curved lenses configured to decode three dimensional content and method of fabricating the same. The lenses comprise a polyvinylalcohol polarizer film or similar type of material laminated with triacetate or similar type material on one or both sides, wherein the polarizer film has a polarizing efficiency equal to or exceeding 99% and a transmittance percentage equal to or exceeding 35% and a retarder film (e.g., norbornene copolymer resin) laminated on a front surface of the polyvinylalcohol polarizer film laminated with triacetate and aligned to produce a desired circular polarization responsive to specified retardation wavelengths. Thermoforming and press polishing techniques may be used to fabricate/curve the blanks into lenses. The lenses (optical elements) may be used in an injection molding process to add thickness.
