Abstract: An optical stack for reflecting and transmitting light in a predetermined wavelength range includes stacked first and second optical films, the predetermined wavelength range defining a first wavelength range and a remaining wavelength range. For normally incident light and for each wavelength in a first wavelength range, the first optical film substantially reflects light having a first polarization state, and substantially transmits light having a second polarization state. For each of the first and second polarization states, for wavelengths in the first wavelength range, the second optical film 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, where the second incident angle is greater than the first incident angle by less than about 50 degrees. For wavelengths in the remaining wavelength range, the second optical film reflects at least 80% of light.

Abstract: Polymeric multilayer optical films are described. More particularly, polymeric multilayer optical films having a first optical packet and a second optical packet are described. The second optical packet is disposed on the first optical packet. How the configuration of the layers of the optical packets affect hemispheric reflectivity of the overall film is also described. The polymeric multilayer optical film reflects more than 95% of light from 400 nm to 700 nm at normal incidence.

Abstract: An optical film including a thermoplastic birefringent multilayer optical film and a UV-cured layer disposed adjacent an outer layer of the multilayer optical film is described. The outer layer may a thickness in a range of about 0.3 micrometers to about 1.2 micrometers and the UV-cured layer includes a structured surface opposite the outer layer. The UV-cured layer may have a Tg less than about 30° C. and has a pencil hardness in a range of 2B to 2H.

Abstract: An optical system includes an extended illumination source configured to emit light from an extended emission surface thereof toward a display panel. The emitted light includes substantially distinct blue, green and red emission spectra having respective blue, green and red peaks at respective blue, green and red peak wavelengths, and corresponding blue, green and red full widths at half maxima (FWHMs). The blue FWHM extends from a smaller blue wavelength to a longer blue wavelength. The optical system further includes reflective polarizer disposed on the emission surface of the extended illumination source. The reflective polarizer includes a plurality of first polymeric layers. The optical system also includes an optical filter disposed between the reflective polarizer and the emission surface of the extended illumination source.

Abstract: A display system includes a light source configured to emit light from a light exit surface, the emitted light having an emitted wavelength. An optical filter is disposed on the light exit surface of the light source. One or more light converting films are disposed between the optical filter and the light exit surface of the light source. The one or more light converting films are configured to receive the emitted light from the light source and convert at least portions of the received emitted light to blue, green, and red lights having respective blue, green and red wavelengths. For a substantially normally incident light and for at least an in-plane first polarization state, the optical filter reflects more than about 80% of the incident light having the emitted wavelength, and transmits greater than about 60% of the incident light for each of the blue, green and red wavelengths.

Abstract: A backlight for an image forming device includes spaced-apart front and back optical reflectors defining an optical cavity therebetween, and at least one light source for emitting light into the optical cavity. The front optical reflector may be disposed between the image forming device and the back optical reflector.

The back optical reflector may reflect at least 70% of light for each wavelength in the first wavelength range, and may transmit at least 70% of light for each wavelength in the second wavelength range. The emitted light may have at least one wavelength in the first wavelength range and at least one wavelength in the second wavelength range.
