Claim 9:
10. A display device comprising:
a first light source comprising a first organic light emitting diode (OLED), a first micro-LED, or a first quantum dot LED (QLED) configured to emit a first light having a first peak wavelength;
a phosphor film configured to receive the first light and to emit a second light having a second peak wavelength that is different from the first peak wavelength;
a second light source comprising a second OLED, a second micro-LED, or a second QLED configured to emit a third light having a third peak wavelength; and
a non-phosphor film configured to receive the third light and to transmit a fourth light having a fourth peak wavelength that is different from the third peak wavelength, wherein the non-phosphor film comprises color filtering properties to filter the third light to thereby shift a peak wavelength from the third peak wavelength to the fourth peak wavelength.
