Abstract
A polarized interference recycling backlight module for generating light with a single polarization state, which reduces the optical loss in light beam output, is suitable for mass production, and decreases manufacturing costs, is disclosed. The backlight is easily integrated with conventional electro-optical display devices and achieves high-quality polarization. The polarized interference recycling backlight module according to the present invention comprises an optical cavity and interference polar (I-Polar) composed of stacked layers. At least one layer of said I-Polar is optically anisotropic and is made by means of Cascade Crystallization Process, is 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 in the visible spectral range, and is formed by rodlike supramolecules representing at least one polycyclic organic compound with a conjugated π-system and ionogenic groups. Another aspect of the present invention is a liquid crystal display incorporating the polarized interference recycling backlight module.
