Claim 0:
1. A display device comprising:
a light source configured to emit a first light having a first peak wavelength; and
a liquid crystal display (LCD) module comprising:
a first sub-pixel comprising a phosphor film configured to receive a first portion of the first light and to emit a second light having a second peak wavelength that is different from the first peak wavelength; and
a second sub-pixel comprising a non-phosphor film configured to receive a second portion of the first light and to transmit a third light having a third peak wavelength that is different from the first peak wavelength, wherein the non-phosphor film comprises color filtering properties to filter the second portion of the first light to thereby shift the first peak wavelength to the third peak wavelength, and wherein the first and third peak wavelengths are in a blue wavelength spectrum of a visible spectrum.
