摘要： An enhanced K-type polarizer includes a molecularly oriented sheet of polyvinylalcohol/polyvinylene block copolymer material having polyvinylene blocks formed by molecular dehydration of a sheet of polyvinylalcohol wherein the molecularly oriented sheet comprises light-polarizing molecules of polyvinylalcohol/polyvinylene block copolymer material varying in length, n, of conjugated repeating vinylene unit of the polyvinylene block, wherein an absorption concentration of each of the polyvinylene blocks in the range of n=19 to 25 is not less than approximately 65% of the absorption concentration of any of the polyvinylene blocks in the range of n=14 or 15, wherein the absorption concentration is determined by absorption of wavelengths from about 200 nm to about 700 nm by the polyvinylene blocks, and wherein the molecularly oriented sheet exhibits a photopic dichroic ratio, RD, of at least approximately 75.

摘要： A method for making a polarizer from a polymeric film having an original length and comprising a hydroxylated linear high polymer includes stretching the polymeric film to a stretched length of from about 3.5 times to about 7.0 times the original length, immersing the polymeric film in an aqueous dehydration catalyst, and heating the polymeric film and the catalyst to effect partial dehydration of the polymeric film, wherein light absorbing, vinylene block segments are formed.

摘要： A liquid crystal display structure includes a liquid crystal display cell having a front surface and a back surface. One or more intrinsic polarizers lacking protective coatings thereon, such as K-type polarizers and thin KE polarizer sheets, are disposed adjacent to the front and back surfaces of the liquid crystal display cell. Alternatively, thinly cladded or encased iodine polarizers are disposed adjacent to the front and back surfaces of the liquid crystal display cell. The liquid crystal display structure may be used in conjunction with other optical display elements to enhance the brightness and contrast of the liquid crystal display.

摘要： A polarizer is used with a liquid crystal display (LCD) cell whose liquid crystal molecules are switched in the plane of the cell. The LCD has birefringent properties that are different from other types of LCD cell and, unlike other types of LCD, the image contrast is maintained and there is little color shift in the dark state when a low birefringence polarizer is used with the SIP LCD cell. In one embodiment, the x-z retardation of the layers between the polarization-sensitive absorbing layer and the LCD is less than 20 nm. In another embodiment, the x-z birefringence is less than 0.0005. The low levels of retardation and birefringence may be achieved by omitting the commonly used cellulose triacetate layer between the polarization-sensitive absorbing layer and the LCD.
摘要翻译：偏振器与液晶显示器（LCD）单元一起使用，其液晶分子在单元的平面中被切换。 LCD具有与其他类型的LCD单元不同的双折射性质，并且与其它类型的LCD不同，保持了图像对比度，并且当与SIP LCD单元一起使用低双折射偏振器时，暗态中几乎没有颜色偏移。在一个实施例中，偏振敏感吸收层和LCD之间的层的x-z延迟小于20nm。在另一个实施方案中，x-z双折射小于0.0005。可以通过在偏振敏感吸收层和LCD之间省略常用的三乙酸纤维素层来实现低水平的延迟和双折射。
