Dual color guest-host polarizers and devices containing guest-host polarizers

摘要

A guest-host polarizer is disclosed that includes a host matrix, one or more first guest dyes disposed in the host matrix and oriented to absorb a first portion of visible light having a first polarization state, and one or more second guest dyes disposed in the host matrix and oriented to absorb a second portion of visible light having a second polarization state orthogonal to the first polarization state. Such guest-host polarizers can be used in various optical applications and display constructions.
