Abstract
A display is provided. The display includes a plurality of light-emitting elements configured to emit a first light associated with a first predetermined wavelength band. The display also includes an optical assembly including a reflective polarizer, a color conversion layer, and a color filter layer. The optical assembly is configured to at least partially convert the first light associated with the first predetermined wavelength band into a second light associated with a second predetermined wavelength band, the second light being a polarized light of a predetermined polarization.
Claims19
A display, comprising:
- a plurality of light-emitting elements configured to emit a first light associated with a first predetermined wavelength band;
- and
- an optical assembly including a reflective polarizer, a color conversion layer, and a color filter layer, the optical assembly configured to at least partially convert the first light associated with the first predetermined wavelength band into a second light associated with a second predetermined wavelength band, the second light being a polarized light of a predetermined polarization,
- wherein the reflective polarizer is configured to selectively reflect or transmit a light depending on a polarization of the light when the light is associated with the first predetermined wavelength band, and transmit the light independent of the polarization of the light when the light is associated with a wavelength band outside of the first predetermined wavelength band.
