Classification: CPC G | IPC G

Claim 14:
15. A display device comprising:
a light source configured to emit a first light having a first peak wavelength in a blue wavelength region of a visible spectrum;
a quantum dot film, positioned on the light source, configured to emit a second light having a second peak wavelength that is different from the first peak wavelength and is in a red or green wavelength region of the visible spectrum; and
a non-phosphor film, positioned on the array of light sources, configured to transmit a third light having a third peak wavelength that is different from the first peak wavelength and is in a blue wavelength region of the visible spectrum, wherein the non-phosphor film comprises color filtering properties to filter a portion of the first light to thereby shift the first peak wavelength to the third peak wavelength.
