AI Technical Summary
Technical Problem
Optical laminates using dichroic organic dyes in polarizing films experience haze changes due to temperature variations, which affect the reliability and performance of thin lenses in image display devices.
Method used
An optical laminate is designed with a resin layer adjacent to a dichroic organic dye-based polarizing film, having an elastic modulus of 1.0×10⁶ Pa at 85°C, to stabilize haze levels by acting as a barrier against dye leakage.
Benefits of technology
The resin layer suppresses haze changes due to temperature fluctuations, ensuring excellent haze reliability and improved visibility in display systems.
