    Abstract: A reflective polarizer has substantially distinct blue, green and red-infrared reflection bands for substantially normally incident light. A display system includes a display panel including blue, green and red light emitting pixels having respective blue, green and red peak wavelengths and respective blue, green and red FWHMs; and the reflective polarizer disposed on the light emitting pixels. The reflective polarizer: reflects at least about 60% of the incident light for each of the blue and green peak wavelengths and at least about 40% of the incident light for the red peak wavelength for a first polarization state; transmits at least about 60% of the incident light for each of the blue, green and red peak wavelengths for an orthogonal second polarization state; and has an absorption peak at a wavelength between the green and red FWHMs.

    Abstract: An optical stack (100) includes an optical diffuser (10) and a first reflective polarizer (40) disposed on the optical diffuser (10). For substantially normally incident light and for nonoverlapping first and second wavelength ranges, the optical diffuser (10) has a first scattering rate R1 for at least one wavelength in the first wavelength range, and a second scattering rate R2 for at least one wavelength in the second wavelength range, such that R1/R2 is greater than or equal to 2. The first reflective polarizer (40) may transmit at least 40% of light for a first polarization state for each wavelength in the first wavelength range, may reflect at least 70% of light for an orthogonal second polarization state for each wavelength in the first wavelength range, and transmit at least 40% of light for each of the first and second polarization states and for each wavelength in the second wavelength range.

    Abstract: Polarizer stacks are described. More particularly, polarizer stacks that include an absorbing polarizer and multiple reflective polarizers, including at least one collimating reflective polarizer are described. Such polarizer stacks are capable of emitted light that is both collimated and color neutral. Backlights incorporating such polarizer stacks are also described.
