摘要：
An optimization method was developed for improving the designs of broadband linear polarization converters using a twisted nematic liquid crystal film and two uniaxial compensation films. As compared to the Poincare Sphere approach, our optimization method takes the material dispersions into consideration and results in a broader bandwidth. Such a broadband half-wave film is particularly useful for enhancing the light efficiency of liquid crystal display devices.
