Abstract

A display includes a pixelated emission surface including a plurality of blue, green and red light emitting pixels having emission peaks at respective blue, green and red peak wavelengths. The display includes a plurality of blue light emitting sources aligned to the plurality of blue, green and red light emitting pixels in a one-to-one correspondence. An optical film is disposed between the emission surface and the plurality of blue light emitting sources. Each region of the optical film that is disposed between a blue light emitting source and the corresponding blue light emitting pixel transmits at least 70% of substantially normally incident light having the blue peak wavelength. Each region of the optical film that is disposed between a blue light emitting source and the corresponding green or red light emitting pixel reflects at least 50% of substantially normally incident light having the blue peak wavelength.
