[LCTp1-4L] Enhanced Utilization of Ambient Light by Optical Films Coupled to a Luminescent Waveguide
luminescent waveguide, optical film, ambient contrast ratio, liquid crystal
Ambient light is converted to photoluminescence photons in a luminescent waveguide. A reflector placed below increases the upward flux by a factor of 1.7. A lightdiffusing film attached to its bottom surface improves this factor to 2.2. The ambient light redirected by these films would narrow a color gamut.
