“…6,8,9 However, especially in the first half of this century, attention was largely focused on dichroic polarizers, which were primarily used in applications such as antiglare sunglasses, photography filters, and optical instruments ͑microscopes͒. [10][11][12] Nowadays, these linear polarizers are also widely used in flat panel display applications such as twisted nematic ͑TN͒ and super twisted nematic ͑STN͒ displays, [13][14][15][16][17][18] were they serve a dual purpose; a first polarizer is used to generate linearly polarized light. The TN or STN cell contains a low molecular weight, liquid-crystalline material, which modulates the polarization direction of the polarized light dependent on the presence or absence of an electrical field.…”

Lett. 89, 051906 (2006); 10.1063/1.2234297 High performance Feussner-type polarizers based on stretched poly(ethylene-terephthalate) filmsHere, we present the results on the optical characteristics of polymeric, linear polarizers produced from oriented, two-component, polymer blends. By a proper selection of materials and drawing conditions, the refractive index of the dispersed phase of the blend is matched with the ordinary refractive index of the birefringent continuous phase while, at the same time, a large refractive index mismatch is generated in the perpendicular direction. The films are, therefore, transparent or opaque, dependent on the polarization direction of the incident light and act as linear polarizers with a high contrast ratio ͑Ϸ1000͒ between the transparent and opaque state. These polarizers are all-polymer-based linear polarizers that operate on the anisotropic scattering of light, instead of anisotropic absorption, which offers some unique features and advantages.

“…A polarizer had been developed with various applications, such as antiglare sunglasses, photography filters, and optical microscopes. [1][2][3] Nowadays, polarizers are essential optical devices in flat panel displays, particularly in liquid-crystal display (LCD) devices. The brightness of displays is adversely affected by the polarization filters, 4,5) which in the LCD system are commonly conventional dichroic polarizers [6][7][8] that are positioned on the light guide plate to selectively absorb the light component in the undesired polarization direction, and thus at least 50% of the incident light is lost by absorption.…”

A nonabsorbed-type polarizer consisting of aligned birefringent fiber/isotropic polymer composites was fabricated. By selecting a matrix polymer with the appropriate refractive index that was matched with the ordinary refractive index or extraordinary refractive index of the fiber, two different types of film were obtained. Both of these different types of film showed the polarization property due to the scattering and transmission depending on the polarization direction. Furthermore, taking advantage of these different optical characteristics between the two types of film, we fabricated an efficient polarizer by combining two films vertically, which was expected to achieve a high contrast ratio between two components of polarization light.
