Patent ID: 7450194

Claim:
A polarized interference recycling backlight module, comprising an optical cavity serving as a light source, and reflecting and randomizing light that is incident upon a front surface of said optical cavity, an I-Polar comprising stacked layers, wherein said I-polar is situated opposite the front surface of the optical cavity and ensures transmission of light with a predetermined polarization state and reflection of light with orthogonal polarization state in at least one region of the spectrum of light, and wherein at least one layer of said I-Polar is optically anisotropic, being made by means of Cascade Crystallization Process and characterized by a globally ordered biaxial crystalline structure with an intermolecular spacing of 3.4±0.3 Å in the direction of one of optical axes, is transparent throughout the visible spectral range, and is formed by rodlike supramolecules, which represent at least one polycyclic organic compound with a conjugated π-system and ionogenic groups.
