1results about How to "Small phase difference" patented technology

Examples relate to thin films, transparent laminates, applications as cover films, and multilayer electronic devices incorporating the thin film, which possess excellent optical properties such as refractive index, haze, and yellowness, as well as excellent mechanical properties. The thin film includes an elastic layer with a refractive index of 1.48 to 1.58 and a low-temperature damage index (the difference between tensile modulus and tensile strength at a specific temperature), wherein the low-temperature damage index of the elastic layer at -40°C is below 1300 MPa.
