Abstract
A modulator and system used to display motion pictures is provided. The design comprises a sheet polarizer and a SMD electro-optical modulator configured to operate in a steady state (non-switching) mode. The modulator is formed from two substantially parallel relatively clear plates, such as glass, two coatings of a transparent conductor, such as indium tin oxide, located between the two substantially parallel relatively clear plates, two polyamide layers located between the two coatings of the transparent conductor, and a film of liquid crystal material located between the two polyamide layers.

9. A projection system, comprising:
-
a surface mode device (SMD) configured to create circular polarized light using a sheet polarizer in combination therewith;
a projection screen comprising projection screen binder materials; and
selection device eyewear wearable by a user and comprising at least one analyzer usable to view images projected using the SMD onto the projection screen;
wherein the SMD is configured to operate in a steady state mode that enables tuning the SMD to substantially the wavelength of each analyzer, thereby correcting for phase shifting resulting from birefringence produced by the projection screen binder materials. - View Dependent Claims (10, 11, 12, 13)
