Polarizer devices and processes of manufacture

摘要

A simple and innovative process for manufacturing a high performance mechanical polarizing device is provided. The invention utilizes an inexpensive, high output production process where a transparent film substrate is coated with a non-transparent layer by deposition or other wet or dry method. Then a photoresist or a nano-imprint lithography process is used to overlay the non-transparent coated film with a pattern. The exposed non-transparent material is then removed by means of acid or base etching or the use of other mechanical or nano-technology removal methods. The photoresist is then removed and a protective layer may then be applied to the polarizer substrate. According to another embodiment, nano-imprinting techniques are used to prepare the polarizer substrate. The process may be automated in one or more embodiments, and lends itself to a high speed production manufacturing line, utilizing roll-to-roll, sheet fed or other methods of automated manufacturing.

主权项

1. A roll-fed or sheet-fed manufacturing process for producing a mechanical polarizer device comprising:
a) providing a first transparent layer; b) directly depositing a non-transparent layer onto the first transparent layer, and creating a pattern of non-transparent layer on the first transparent layer by one of:
i) removing a portion of the non-transparent layer to create a pattern of non-transparent layer on the first transparent layer; orii) directly depositing the non-transparent layer on the first transparent layer in a pre-determined pattern; c) removing a first protective film from a first side of a transparent adhesive layer; d) depositing the first side of the transparent adhesive layer onto the non-transparent layer; e) removing a second protective film from a second side of the transparent adhesive layer; and f) depositing a second transparent layer on top of the second side of the transparent adhesive layer to produce the mechanical polarizer device.
