  • Backlighting for display systems
    Patent number: 11782310
    Abstract: A display system includes a light source configured to emit light from a light exit surface, the emitted light having an emitted wavelength. An optical filter is disposed on the light exit surface of the light source. One or more light converting films are disposed between the optical filter and the light exit surface of the light source. The one or more light converting films are configured to receive the emitted light from the light source and convert at least portions of the received emitted light to blue, green, and red lights having respective blue, green and red wavelengths. For a substantially normally incident light and for at least an in-plane first polarization state, the optical filter reflects more than about 80% of the incident light having the emitted wavelength, and transmits greater than about 60% of the incident light for each of the blue, green and red wavelengths.
