1. Light-Polarizing PL Polymers
Orientation Mechanism

2. Linear Polarization of Light
Introduction
Linearly polarized light is usually generated by the use of dichroic polarizers
Applications:
Liquid crystal displays, sunglasses, optical filters
Dichroic Polarizer:
Uniaxially oriented absorbing dyes, linearly polarized
absorption, efficiency < 45 %
Photoluminescent (PL) Polarizer:
Uniaxially oriented luminescent molecules, linearly polarized emission,
Combination of polarizer and ‘active’ color filter
