Abstract: An optical stack includes a reflective polarizer, an absorbing polarizer, and a half-wave retarder. The half-wave retarder is disposed between the reflective and absorbing polarizers. For substantially normally incident light and a first polarization state, the reflective polarizer reflects at least about 60% of the incident light for at least a first wavelength less than a cut-off wavelength and transmits at least about 50% of the incident light for at least a second wavelength greater than the cut-off wavelength. For substantially normally incident light, the half-wave retarder has a first retardance of less than about 250 nanometers (nm) at the first wavelength and a second retardance at the second wavelength. A deviation of the first retardance from a first half-wave retardance corresponding to the first wavelength is less than a deviation of the second retardance from a second half-wave retardance corresponding to the second wavelength.

Abstract: A reflective polarizer is such that for substantially normally incident light and for blue, green and red wavelengths, the reflective polarizer: has a transmission spectrum including a blue transmission stop band for the incident light polarized along a first direction; reflects at least about 50% of the incident light polarized along the first direction for the blue wavelength; transmits at least about 50% of the incident light polarized along an orthogonal second direction for each of the blue, green and red wavelengths; and transmits between about 50% and about 95% of the incident light polarized along the first direction for each of the green and red wavelengths. The blue transmission stop band has opposing first and second band edges having respective first and second slope magnitudes S1 and S2, where S1/S2≥2. A display system includes the reflective polarizer disposed on a display panel.

Abstract: A display system includes a display panel including a plurality light emitting pixels and a reflective polarizer disposed on the light emitting pixels. The reflective polarizer can have a reflection band having a lower overlap with an emission spectrum of red light emitting pixels for substantially normally incident light and a higher overlap with the emission spectrum of the red light emitting pixels for at least one incident angle greater than about 40 degrees. The reflective polarizer can have a reflection band overlapping an emission spectrum of blue light emitting pixels for substantially normally incident light.

Abstract: An optical system (200) includes an emissive display (220) and a reflective polarizer (100) disposed on the display (220). The display (220) includes a blue pixel (222b) emitting light having a peak at a wavelength λb. For substantially normally incident light: for the wavelength λb, the reflective polarizer (100) reflects at least 30% of the incident light having a first polarization state (b) and transmits at least 75% of the incident light having an orthogonal second polarization state(a); and for at least one wavelength λ1 greater than λb, λ1-λb≤50 nm, the reflective polarizer (100) transmits at least 75% of the incident light for each of the first and second polarization states. For the wavelength λb, the reflective polarizer (100) has a maximum optical transmittance Tmax for light incident at a first incident angle, and an optical transmittance Tmax/2 for light incident at a second incident angle greater than the first incident angle by less than about 50 degrees.

Abstract: An optical construction includes a lens film having an outermost structured first major surface and an opposing outermost substantially planar second major surface. The first major surface includes a plurality of microlenses. A radiation cured optically opaque mask layer is disposed on the second major surface of the lens film. The mask layer has an average thickness of less than about 10 microns and defines a plurality of laser-ablated through openings therein. The through openings are aligned to the microlenses in a one-to-one correspondence, such that for a light incident on the structured first major surface along an incident direction forming an incident angle with the second major surface, an optical transmittance of the optical construction as a function of a transmitted angle includes a first transmitted peak having a first peak transmittance T1≥40%. The first transmitted peak can be within about 10 degrees of the incident angle.
