    Abstract: A multilayer partial mirror includes a plurality of alternating first a second polymeric layers numbering at least 50 in total, disposed between, and integrally formed with, opposing first and second polymeric skin layers. For a visible wavelength range extending from about 420 nm to about 680 nm and an incident light propagating in an incident plane that includes a x-direction, and for an s-polarized incident light, the multilayer partial mirror has an average reflectance Rs1 for a first incident angle of less than about 10 degrees, and an average reflectance Rs2 for a second incident angle of greater than about 45 degrees, and for a p-polarized incident light, the multilayer partial mirror has an average reflectance Rp1 for the first incident angle, and an average reflectance Rp2 for the second incident angle. Each of Rs2/Rs1 and Rp2/Rp1 is greater than about 1.15.

    Abstract: An optical construction includes a reflective polarizer having a structured major surface, and an optically diffusive layer conformably disposed on the structured major surface so that opposing first and second major surfaces of the optically diffusive layer substantially conform to the structured major surface. The optically diffusive layer includes a plurality of nanoparticles defining a plurality of voids therebetween. For normally incident light and visible and infrared wavelength ranges: in the visible wavelength range and for a first polarization state, the optical construction has an average total transmittance of greater than about 40% and an average specular transmittance Vs; in the visible wavelength range and for an orthogonal second polarization state, the optical construction has an average total reflectance of greater than about 80%; and in the infrared wavelength range, the optical construction has an average specular transmittance Is, Is/ Vs ≥ 2.5.

    Abstract: Modular displays and methods of assembling modular displays are disclosed. The displays include a display element and a base element. The base element includes a light source configured to inject light into the display element, and electronics to drive the display element when the display element is attached to the base element. The display element includes a lightguide and a display panel, such as a liquid crystal display (LCD) panel. The base element further includes a receptacle configured to accept the display element and couple the light source to the lightguide, and couple the electronics to the LCD panel. The display element and the base element can be removably attached to each other. The base element and the display element can each be configured so that different display elements can be attached to the same base element, providing flexibility of modular display design.

    Abstract: A backlight suitable for use in a display device includes an illumination device having at least one light source and a back reflector stack including a reflective layer and a transparent layer having substantially uniform refractive index and having a plurality of light-directing protrusions disposed in a matrix array. The transparent layer is disposed between the reflective layer and the illumination device with the plurality of light-directing protrusions facing away from the reflective layer. The plurality of light-directing protrusions are configured and disposed in a configuration that is not registered to any light source of the illumination device.

    Abstract: 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.
