Latest Patents

David J McDaniel holds 1 patent for his invention related to optical film and optical stack. His patent describes an optical film that consists of alternating first and second polymeric layers. The first polymeric layers have a smaller average in-plane index of refraction compared to the second polymeric layers. Additionally, the first polymeric layers possess a glass transition temperature of at least 107 degrees Celsius. This optical film can function as a reflective polarizer. The optical stack includes a linear absorbing polarizer and the reflective polarizer, which is bonded to the absorbing polarizer. The reflective polarizer achieves an optical reflectance of at least 60% for a first polarization state and an optical transmittance of at least 60% for an orthogonal second polarization state. Notably, when subjected to heating at 105 degrees Celsius for 15 minutes, the difference in shrinkage between the reflective polarizer and the absorbing polarizer along the first and second polarization states is greater than about zero and 0.2%, respectively.
