Patent number: 12535630Abstract: An optical construction includes a reflective polarizer and an optical film. The optical film includes a matrix and a plurality of first particles dispersed in the matrix. Each of the matrix and the plurality of first particles includes a silicone polyoxamide and an acrylate polymer. For substantially normally incident light and for at least a first wavelength in a first wavelength range, the reflective polarizer reflects about 60% for a first polarization state and transmits about 40% for an orthogonal second polarization state. For at least a second wavelength in a second wavelength range, each of the reflective polarizer and the optical film transmits about 60% of an incident light for each of the first and second polarization states. For at least the first wavelength, optical film has an optical haze and a depolarization ratio. A ratio of the depolarization ratio to the optical haze is less than 0.1.Type: GrantFiled: November 2, 2021Date of Patent: January 27, 2026Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Bharat R. Acharya, Brett J. Sitter, Robert D. Taylor, Zhicheng Tian, James P. DiZio, Quinn D. Sanford, Kent C. Hackbarth, Matthew E. Sousa
