Abstract:
A display (1000) including a display panel (130) and a polarizer (110) disposed to receive a light (150) output of the display panel (130) is described. The polarizer (150) may be a reflective polarizer (110) or a circular polarizer (100) incorporating a reflective polarizer (110). The display panel (130) includes a plurality of pixels and each pixel includes a plurality of subpixels. The reflective polarizer (110) has a first reflection band, wherein at normal incidence, the first reflection band has a long wavelength band edge wavelength between peak emission wavelengths of two subpixels in the plurality of subpixels. The reflective polarizer (110) may be disposed between an absorbing polarizer (106) and a retarder (108) in a circular polarizer (100). The reflective polarizer (110) may have substantially non-overlapping first, second, and third reflection bands.
